Title: LIVE: Ares I-X Countdown and Launch ATTEMPT 2 Updates
Post by: Chris Bergin on 10/28/2009 04:12 am
LIVE interactive coverage for Ares I-X launch countdown (and launch).

This is interactive, but will remain focused on updates. Use the other threads for items such as viewing the launch, weather and general woo hooing cheerleading posts. The site will get very busy as we get closer to launch, so please appreciate the thread needs to run on updates, not random posts.

A _lot_ of lightning last night, just after 10pm local time. Several strikes within 1/2mi of the pad. Almost every rain gauge at KSC picked up some sort of drops - some up to an inch... The sensors on either side of Pad B had the most at 0.90" on one side and 0.81" on the other.

So if the "five hole sensor" is clogged due to water and ice, and stops working....aren't there over 700 sensors on the vehicle that can help the Ares team get the data they need anyway?

Edit: if the five hole sensor doesn't work during the prelaunch test, is that an automatic scrub condition now?  That's kind of what I'm getting at.

Second launch attempt article: http://www.nasaspaceflight.com/2009/10/live-ares-i-x-second-launch-attempt/

Mulled over what to do with this one (not short on info thanks to L2, but wanted an angle). Decided to go with the parachute recovery system - so there's I-X/Ares I JDTV and the failure on STS-128 covered in the above.

Just feel it's more interesting than going on about the weather (sorry Rob! ;D) - which most of the other sites seem to have made the basis of their second attempt article.

Just finished reading all the posts in the first launch attempt. Thanks to all the posters for their reports. Launch time is 10:30pm ACDT here in Adelaide, South Australia. Its been awhile since I watched a live launch, but I think this is an historic flight so I want to see it go live. Stayed up to 2am last night for the first attempt. Hope today's attempt has better luck!

George Diller's discussing the need to take a "more deliberate" approach to powering up the electrical systems due to last night's lightning strike.  They've started NASA TV live coverage.

RSS retraction at 6 am Eastern, Upper stage access arm retraction between 5:30-5:45 Eastern, as of right now.  Ready to launch another weather balloon.

Looking at liftoff between 8:15-8:30 am.  Development flight instrumentation powered up.

Discussion of the five hole probe.  They tested a spare probe and placed it in the rain, taking it to the lab now.  Likely to see degraded data but they will try to compensate it and calibrate it with the spare probe data.

Maybe whilst we're in the hold, someone who knows could say how the big clock is operated.  Is it manually controlled from launch control or elsewhere? Or is it automatic and tied into the coundown autosequencer?

Late RSS retraction

To repeat. They are red triboelectrification. Should be getting better for about 8:30, but they have to follow their count proceedures and won't be ready. They are also checking the lightning data from overnight.

Triboelectrification, it´s a possible interaction between the vehicle and the clouds than can create RF interference and prevent the range from using the flight termination system.

Flight team is going through all the systems to make sure that the vehicle is ready from the effects of last night's thunderstorm.  "Targeting NET 9am EDT for launch" (but expect 9:30am EDT if all goes well).  Nothing has come up so far that has become a constraint or a concern, which is good.

Jon Cowart: "Only red due to weather.. T-38s flying to get a way around this triboelectrification.  Heading to 10:30am as our best launch time right now.  If there is something that pops up beforehand, we can always pull the launch time back in, but the best T-0 for right now is 10:30am EDT.  That's the target.  Lightning last night, had 154 strikes within 5 miles.  Had to verify that the rocket was good to fly, which leads to a few waivers that we have to process.. but all the data shows everything is good.  Instrumentation in the CWS didn't detect the strikes, nor the lightning towers.  Nearest strike to the rocket was 700 yards away, which led to a field strength of 20% of the point of where we would be concerned.  Rocket is fine."

Post by: Retired Downrange on 10/28/2009 12:13 pm
The weather aircraft observing limits of the thin cirrus cloud deck causing the concern says the edge is 45 miles out on the 290 radial from pad. (This clearing is moving toward the pad.) From that point he says the sky looks clear as far as they can see to the north.

[edit - add below]
The edge of this clearing is oriented along a NW to SE line, so if you check due north of the pad, the clear area is only 20 miles from the pad, and the cloud deck appears to be dissipating along the edge.

"According to the 45th Weather Squadron of the Air Force – the Squadron responsible for monitoring all launch weather rules – Triboelectrification is defined as: “triboelectric charging observed to put aircraft and space vehicles into corona when they fly through clouds containing ice or precipitation in either phase.

“The corona generates radio signals known as P-static (Precipitation static). P-static can degrade the signal to noise ratio of critical communications to the vehicle, especially including the range destruct command link.

“In all, the triboelectrification Flight Rule is one that NASA has not concerned itself with for several years, as the Space Shuttle is not susceptible to this phenomenon and most EELVs (Enhanced Expendable Launch Vehicles) are coated to protect against it.

According to the 45th Weather Squadron of the Air Force – the Squadron responsible for monitoring all launch weather rules – Triboelectrification is defined as: “triboelectric charging observed to put aircraft and space vehicles into corona when they fly through clouds containing ice or precipitation in either phase.

“The corona generates radio signals known as P-static (Precipitation static). P-static can degrade the signal to noise ratio of critical communications to the vehicle, especially including the range destruct command link.

“The triboelectrification rule is designed to protect those critical communications links.”

The triboelectrification Flight Rule can come into effect under cloud cover conditions of 5/8 or greater when the clouds are “above the 14 deg F level up to the altitude at which the vehicle’s velocity exceeds 3000 ft/sec,” notes the I-X Weather Launch Commit Criteria."

What I don't understand is if T/E was a known issue, why didn't the 1-X get the same coating that most EELV's do? If the reason was cost, how much do all these delays cost?

Launchpad911, as I understand it, the triboelectrification issue is unique to Ares I-X. Or at least unique enough not to bother with avoiding it on other launches.

Pad 39B looks like crap with  the two old Tail Service Mats still there awkwardly but the FSS tower is only about half as tall as the spacecraft...not to mention those unsightly lightning masts towers they built around the pad.  I am just HOPING that this is still a work in progress and the pad will be modified and configured to look like a decent launch pad by the time they are ready to send astronauts on Ares.  Right now it looks like crap.

Not that it will ever be an issue due to possible cancellation, but I can see the triboelctrification issue being REALLY annoying (delay after delay) with future Ares I launch attempts when and if we do ever get to manned flights.

Again, it was noted in previous posts that Ares I would not have this issue, as there would be tests to ensure that triboelectrification would not be an issue.

Just to clarify. The actual Ares-I system will not suffer from the triboelectrification constraint.

With regards to the lightning masts, they are there to stay (at least for Constellation).

Info on future pad changes and construction issues can be found elsewhere on the site.

I think I remember reading that the FSS and RSS on both LC-39 pads were suffering from corrosion problems, partly caused by exhaust products from the SRBs.  Consequently, both will need to be replaced no matter what system replaces the shuttle.

Well said! You're hurting padrat's feeling with that talk!! :)

I think the pad is actually looking pretty good with the masts, and the short FSS makes the rocket look vastly more impressive than it is!

Lets not forget, this is the 3rd tallest rocket ever, and the taller rockets have not flown for decades!

There was a 6 year gap between ASTP mission and STS-1.  The pads had already been converted to shuttle as well as the MLPs.  It would basically have been impossible other than as a public relations gimmick to have done something like that.  And they would have had to stack a Saturn that would never have flown.

They were moving back and forth yesterday, so that's a fair question....but they are sticking with a 11am T-0.

Given the calls being made right now, they must need to go through an amount of proceedures prior to coming out of the hold - thus the launch time.

Bottom line - Mr Mango knows best.

I remember looking at the Saturn V on its side by the VAB, then looking at STS-1 on the pad same day. You could see both the pad and the VAB from the press site, but I can't clearly remember if I could see that Saturn from where I was standing by the countdown clock. However, I did dig up a couple of photographs I took from the press site that appear to be from somewhere near the ditch to the "left" of the press site (left, if you're facing that pad). One clearly shows the pad, the other shows the VAB (and a lot of people in sloppy 1981-style clothing). Behind the VAB is a red Apollo-era MLP, and you can glimpse what appears to be a segement of the Saturn on the ground. I didn't think to take a 360-pan, sad to say.

The launch rules are so stringent that it's virtually impossible to book the range in advance and then expect absolutely perfect cloudless weather and no other impediments.

If they don't go today while they own the range, they might wait 'forever'.

15:08 Zulu is the new T-0.

They will likely bump this down by 5 to 10 minutes a time if no go for each attempt. Got to get off in the next 60 minutes.

Why was tribo never an issue with Saturn?  They launched through cirrus layers, and I don't recall any mention of coatings.

That's an understatement.  Apollo 12 actually got hit with a lightning bolt, temporarily lost the Command Module computer and had to complete ascent on the LV's avionics only.

I just think they are being extra careful with Ares-I-X because, in the end, 45th SW really doesn't like it and suspects that it could go runaway with little or no warning.  They don't want to lose the ability to blow it even for a second if they can avoid it.

There wouldn't be one. The tribo-electirification could cause communications problems. The main concern is with the FTS (Flight Termination System). The Range folks need to be totally sure they can terminate the rocket should something go wrong. I dont' see there is any leeway on this.

Sorry for saying this: Even with this being a one time test launch, the restrictive rules are really extreme. And I am not saying this because I can't wait to see this vehicle flying. :) Really. I mean, Shuttle is restrictive (TAL, RTLS, rain, crosswinds ...). But todays weather is as best as you can hope for in humid Florida. 20kts winds maximum also are very restrictive.

You pay in operations your failures in development.

That was one issue that they were worried about on this launch. Worried that it might contact the tower, but looked like it cleared. Interested to see how much damage there was with the tower getting more of the direct blast from the SRB.

Have to hear about stage contact and rates later, and maybe not "supposed" to tumble, but as said, it's unguided -- it will eventually develop rates.

It was figured that it would tumble eventually, but can't say that the booster didn't "accelerate" that process. And everyone remember, this is a TEST flight. If there's a time for problems to develop, this is it. So please don't be so quick to label this as a failure. If you'd like the human space program to continue we don't need snap judgements that can accelerate quite quickly.

At hypersonic velocities, it does. One little instability and it goes off. Again, the final Ares I will have ullage motors...

Read your response to my statement.  You can't define a term using itself.  :-\

And hypersonic has nothing to do with it - if an object is stable, it's stable.  If it's dynamically stable, the rates will null as the center of pressure and location of the the shock(s) change with motion.

So again, "unguided" does not equal "unstable."

Or so I learned in MY engineering curricula (including subsonic, supersonic, and hypersonic aerodynamics and compressible flow theory).  Your mileage may vary. :)

Yeah, they will have to be significant ullage motors. *sigh* Well, that was nice. Now we can go ahead and try Jupiter 130/24x, Ares V-lite, Not-Shuttle-C, or EELVs. And, time to watch Masten Space!!! Their clock for the NGLLC starts in like 5 minutes!!! They will have a web stream going.

Right.  I don't see contact.  I see the sep motors fire at the base of the SRB, then the tumble motors as planned.  The SRB tumbles because it was purposely sent into a tumble at that point.

I don't know -- rocking the video back and forth, they both begin to slowly tumble, then the 1st stage seems to bump "upward" and the USS begins spinning at a much faster rate.

Does not look like there was contact, could just be airflow disrupion or the USS just does not fly well on its own :)

This is the only time where the structural constraints are the same.  The forcing function would be the same as Shuttle, but the resulting acceleration oscillation is more Ares-like than Shuttle.

Even if there wasn't recontact.. it appeared to stay in contact long after the Separation event.  Ullage motors are a must.. and this may tell them if they've planned for large enough motors

Ares I-X Using a 4-seg is not as high at sep and there may be more aerodynamic pressure on US than there will be at burnout for Ares I using a 5-seg Solid... although with 5-seg you'll also be moving faster at burnout..  Not sure what which case will be worse.

Something definitely looked fishy about the separation. The NASA animations released before the flight showed a much longer delay between the separation motors and the induced rotation.

The way the US started spinning made it look like *something* was still holding the stages together.

WAS THE USS SUPPOSED TO TUMBLE AFTER SRB SEP??

Yes, it's an unguided lump of metal.

"Unguided" doesn't necessarily mean "unstable."

The question stands.

The primary mission objective for separation (P4) was to "demonstrate First Stage separation sequencing" and is silent about what the upper stage does afterward.  I'd say that they'd demonstrated the separation sequenceing.
You're right. I got really scared when I saw the USS tumbling 'below' the first stage.

Anyhow, I thought the BSM would separate both USS and RSRM before the BTM fired. in this context the USS shouldn't have tumbled.

They ullage can give a little kick, and perhaps put some "retros" on the aft skirt to help slow it down.  Have to be gentle however, dont want to make it worse.

Just seemed to me the yaw move was much quicker.  The cams on the stages will really tell the tale.

The thing is they need to make sure there is NO contact with a live 2nd stage with a J2X in it, that could ruin your whole day.

But it was a good flight, much smoother than I was expecting, just did not know how an Shuttle SRB would do solo.  Had a quite pronounced "lets make sure we dont hit the tower" maneuver, and very fast.

Also did not notice much in the way of "rotation" at all really.

I am sure the final flight vehicle, if it ever is built, will include ullage motors.  The Saturns did and not only for pushing the upper stage away but also to settle the propellant in the upper stage as mentioned.  I believe this second stage had no such active component so the odd separation really doesn't seem to be that odd to me.  Also remember the recent SpaceX failure due to impact between stages at separation.

Yes. The ullage motors are for settling fuel - and they are not gimballed - they have no ability to keep the vehicle pointy end forward. They are not very powerful. I can't recall offhand if there are attitude control jets on second stage - that might help normally. On a real flight, the second stage J2 will not fire immediately (and will not be able to control the stage), so the second stage will need to be stable or stabilized for a few seconds after sep. Also, the J2 nozzle will be sticking out back and recontact with that will have to be avoided. It was expected that eventually for this test the upper stage would tumble, but it wasn't supposed to do what it did.

1.) Ares I-X flew straight as an arrow during ascent

2.) The first and upper stages will not separate at the same location on Ares I as on I-X

2.) The REAL upper stage on Ares I will still be moving forward (on its OWN propulsion) once the first stage separates from it.  Also, if artist concepts and online videos are anything to go by, the upper stage will have its own separation motors to help push it away from the FS after SRB burnout.

The public and Congress should see this flight as MORE of a success than a failure.

Although ullage motors are mostly for fuel settling, they'll have to be used to avoid recontact since SRMs so often (always?) have residual thrust after "burn-out." Of course, people have thought of this before today.

The 1st stage will (and did today) have booster separation motors -- essentially retro-rockets at the base of the aft skirt.

Don't know if they ever said *what* specifically would happen to the upper stage after separation (besides fall into the ocean). 

*After* seeing the launch, I suspect it saw enough of the tumble motor exhaust to start a quick tumble, with no significant airstream at that altitude to counteract the force of the exhaust.  I'll wait for the analysis, though...

 Even worse was the separation......

This separation was as expected.  The USS didn't have any live thrusters, so it entered a tumble.  The booster fired its sep motors, followed immediately by its tumble motors *as planned*.  That sent it into a tumble *as planned*. 

We're just not used to seeing a test like this.

The flight was stable in pitch, yaw, and roll.  The sep was clean.  The stage appears to have parachuted to recovery.

It looks like a very successful test flight, assuming the telemetry flowed well for data downlink.

I've been taking notes from the briefing, since the forum seems to have been down.

Doug Cooke: How cool was Ares 1-X?  It was triboelectrifying!  Can't say enough about this team.  Went from concept to flying in 3 years.  Learned a lot just getting to this point.  Vehicle flew well, and we will learn a lot from the data.

Jeff Hanley: Do not want to hear triboelectrified stuff from now on!  Team is tired, but extremely satisfied.  Couldn't be prouder of the teams.  I was not even sure we were gonna launch because of the lightning strikes.  But the team worked through that issue well to get to the launch.  Very proud of the result

Bob Ess:  Spectacular day.  Vehicle flew better than expected.  Saw the flyaway maneuver at the pad, may have looked strange, but flew perfectly - right down the line.  RoCS fired only 3 times... very benign flight.  Dynamics on the upper stage, working to understand that.  Booster is back in the water... so the parachutes are assumed to have worked well.

Ed Mango:  Fantastic day.  The team really excelled.  We had a great team and a great vehicle.  We just had to wait for mother nature.  Developmental flight stuff is a lot of fun!  We had some challenges getting off the ground.  It's a new rocket... it was our first time working with it.  No problems with the rocket... just learning on our part.  Probe cover was a bit of a challenge, but we were able to get it off.  Weather didn't cooperate after that, so came back today.  Lightning struck last night near pad.  Worked through vehicle step-by-step to build flight rationale.  That was only issue other than weather.  We found a hole in the clouds, and took off through it.

Questions:


Q: Why no visual on chute deploy?  With a test as smooth as this, what are your thoughts on "selling" this rocket.

A: We saw drogues come out, then lost video.  SRB ships saw parachute splashdown, on their way to pick it up.  We are working from Augustine report.  Have been instructed to continue on current path.  This test will be valuable no matter what happens in the future.  We can see how valid our models were.

Q: Been 37 years since we left earth orbit. There is a push for commercial spaceflight, without background experience.  This demonstration was 207th successful flight of SRB.  How will you respond to Augustine report?

A:  Bolden and NASA are looking at the facts from the report.  We are interested in helping commercial ventures through COTS, etc.  They are making progress.  You are seeing experience, but also a streamlined NASA team.  We are learning to do this from the beginning, since we haven't done this in a while.

Q: How successful would you classify this flight?  Have you got any prelim data.

A: Completely met, and blew away our criteria for success.  All onboard data systems worked well.  It will take us a while to look at all the telemetry and collect data from sensors in the booster.  Separation seemed different from predicted, we will need to look at that.

Q: Why are you having a difficult time selling to outsiders that you are "on-time" with this project?

A: I don't know of any data about issues like TO, didn't see any.  We are keeping our heads down and pushing forward with the project.  We had Orion PDR successful.  And a successful 5 seg booster test.  I can't speak for others.  Challenged from budget perspective.  Opinions of others vary, and we still need to understand Augustine report's suggestions.

To update (added some news to the article as the news site was still working).

Still want to see the video for the sep. Had some dynamics on the USS. Didn't use the word recontact at any point.

I have sources saying FS splashed down with two parachutes, with a third failing.

Q: ChrisG!: The probe cover... would it have hindered the flight had it not come off?

A:  We figured we should pull as much as we could before trying anyting else.  We have simulated flying with the cover on.  When it happened we knew what to expect.  Can't say whether we would have flown or not, though.

Q: Did stages contact?

A: Hard to tell.  We need to look at the data.  We know the booster sep motors fired as planned, but don't know if any other conditions affected it.  It was interesting, though.

Q: Did you ever want to shake your fist at the weather gods?

A:  I wish Kathy Winters was here.  She did a tremendous job searching for the right conditions to launch.  We would have liked more chances, but I was happy that we didn't go yesterday, since we would have lost it in the clouds.

I lost video briefly during the separation dynamics, so hopefully will get to see this better...

Sorry if this was already covered in thread, still catching up.  The NASA TV feed (over satellite) had trouble right after separation, for about 20 seconds.  I'll be checking my recordings to see what the deal was, but there was definitely a problem there.  Internet may have been fine, but cable would definitely have seen the problem.

For the record, the NASA TV outage was indeed 20 seconds long.  On the two SD feeds, the bug (logo in upper right corner) persisted, which implies a camera or master control problem.  On the HD feed, the bug disappeared, which implies a master control or distribution problem.

Therefore, I think NASA TV's master control crashed at this point, and I'm glad it waited until sep to do so!

Glad to see that NSF is back up :)  ChrisB, you should have posted something to your Twitter account about the NSF outage ...

I'm not even gonna cover the question about the additional plume and such.  ;)

Q: How significant was roll torque?

A: We saw roll control do 3 firings today.  Sims showed 20-25 times fired.  Much less than expected.  It is another data point showing that this roll torque is very small.  Flight tests like this help reduce uncertainties.

Yes indeed, kudos to him for asking.  I really enjoyed the quip of "it was designed to tumble," after the long detailed answer Bob (I believe it was) gave.

I wonder how different sep would have been for a full 5-seg instead of the dummy 5th stage.

Edit: Adjusted punctuation.

Atlas and Delta have unpowered separations

Sorry Jim, i'm being ambiguous in my haste. I mean of vehicles that have actual powered upper stages..rather than dummy simulators.

I meant powered in that respect, as in real rather than dummy. 

Dynamics are not different

I watched the launch from all the available views and noticed a few things that I hope the experts on here can comment about.

1.  At SRB ignition I noticed the vehicle appeared to "pitch", by that I mean that from the side view the SRB base moved slightly to the left and the Escape Tower appeared to move slightly right less than 2 seconds after ignition.  Is this what it was supposed to do.  I am only talking about a .5 degree or 1 degree pitch.

2.  At SRB separation the booster appeared stable, where the upper stage did not appear to separate cleanly and began to tumble emmediately.  In the CGI sim the opposite was true, where the booster tumbled and the dummy upper stage fired separatioin motors and proceeded straight and true.

Overall it appeared to be a very stable flight with none of the violent rolling and instability that was predicted by some, let alone the G forces staying very close to 3gs for the duration of the flight.

I look forward to responses.

Q: From watching a lot of countdowns, the internal comms seemed a little rocky... is that a fair assessment?

A:  Comms is different than shuttle launches.  Prime launch team did outstanding.  Communications areas will be improved through more flight tests.  This was a learning experience.  We will take lessons from it.  Range and weather communications and support were outstanding.

Q:  What messages do you want the test flight to send to the next generation?

A:  This is fun fun stuff!  This is the time to come join us.  This is the sort of thing that inspired us.  There is interest in going beyond LEO, so this is an exciting time.  This is about people, discovery, and learning things for society and our country.  It proves that anything is possible.  NASA and the space program can do anything and this helps prove anything is possible.  But it is the people that make it happen.

 Even worse was the separation......

This separation was as expected. The USS didn't have any live thrusters, so it entered a tumble.  The booster fired its sep motors, followed immediately by its tumble motors *as planned*.  That sent it into a tumble *as planned*. 

 - Ed Kyle

I think you misunderstood the statement.  The sep did _not_ go completely as expected. The question is not whether the first stage tumbled - everyone knows that was supposed to happen as a planned part of the recovery process. At the press conference just completed it was specifically stated that the immediate second stage tumble was unexpected. That's what was being referred to. It could be a lot of things, aerodynamic effects, proximity aero, recontact, etc.

Q:  Current direction is to keep moving forward. What are big upcoming milestones?  Ares 1-Y?

A:  Next thing is Pad Abort 1.  Test of LAS on Orion.  Capsule is boilerplate, and is at White Sands. Parachutes and abort motor are being installed, and will be fired in the spring.  Beyond that, is Ares 1-Y.  Schedule is always changing, but is planned for March 2014.  Was to be sub-orbital test of 5-seg 1st stage and high-altitude abort.  We want to see if we can attach an engine to the upper stage, we continue to review that.  We are paced by budget for long-lead parts.  Puts pressure on our program towards critical design review.  J-2X engine in being designed and prepped for PDR.  Orion is is being worked on, a ground test article is being built.  Successful PDR in August, now working toward CDR next year.  Orion is largely ready for assembly... just waiting for parts.  ML is under construction.  VAB designs are complete.

I think I might be missing something on the recontact thing. I just watched the HD version and I can't see any recontact. It looks like the initial sep motor firing takes place while the vehicle is behind a cloud, and then the camera changes angles and you can see a big dark blotch on the base of the US that I assume is the hole in the frustrum. Then the tumble motor on the SRM fires and the "nose" of the SRM swings around past that dark section, eclipsing it. THEN the US starts to tumble. So when did the two recontact?

Q:  How much would a funding increase help in speeding up the process?  How much does a good test today increase confidence?

A: More money, sooner is good.  Systems take about 3 years to build, from the time the order is put in.  This includes parts.  So design needs to get done first.  And this puts us in the 2014 range.  Flat nature to our funding curve through this FY, then it jumps after Shuttle retires.  We would like to fly sooner, but funding hasn't materialized.  We need to adjust schedule accordingly.

Bob Ess said that the separation looked good, clean, but that there were some surprises on the upper stage "dynamics" (i.e. tumble rate).  He also said that a tumble like this had been seen in some simulations, the result of slightly off axis but not out of spec positioning at sep, which would mean that it was not completely "unexpected".

It was interesting, but not a big deal.

Q:  Triboelectrification... what would it have taken to certify vehicle?

A:  It's not so much an issue of certification.  You can coat the vehicle to dissipate charge.  Or you can show vehicle is not sensitive to the effect. Shuttle does not have this rule.  It is more a rule for a brand new vehicle.  Our analysis shows Ares 1-X was probably not susceptible to it, but didn't want to take the chance.  You learn from these experiences.

Q:  How many launch times did you set over the last 2 days?  ;)

A:  I don't look at it as a comedy, but it beats any reality show.  There was a bet on how many we would do today.  In reality I would say only 2 times yesterday and once today...  including the time when we got below T-4:00 yesterday, and today when we launched.  You have to set a resume time for this hardware... not exactly like shuttle where you can just pick up the count.  The team did very well working through issues, including the lightning strike.
Title: Re: LIVE: Ares I-X Countdown and Launch ATTEMPT 2 Updates
Post by: vanoord on 10/28/2009 05:22 pm
Looking at that HD version of separation, the upper stage seems to be given a shove from the lower stage which starts the tumbling.

The first two half-rotations for the upper stage take around 6 seconds each, with the next half-rotation (which is cut off just about halfway through) looking as if it's going to take a second or two longer - that would imply (to me) that the impulse which started the tumbling was not aerodynamic forces, but contact from the lower stage.

The issue (presumably) is made worse by the lower stage tumble motors firing whilst the upper stage is in too close a proximity to the upper stage - the cure for this would be slightly later firing of the tumble motors and possibly some method of slightly retarding the lower stage?

That can't be correct??

I know this must have been a slip of the tongue, but they can't go by a 'report; at all, only whet they have been directed to do so far.

I do agree on the value of the test data however...

I will issue congrats to the teams who have worked on getting this rocket to fly, because it did, and you should be proud of that.

Q: Do you regret saying not to read too much into the results from Triboelectrification and from the results from this flight in general?

A:  If this launch had slipped, we had been collecting data to go to the range about waiving the Triboelectrification issue.  Will not be an issue in the future. 

Actual data from the flight will be very valuable.  Regardless of what happens with Ares, this flight will be valuable.  We learned a lot even before launching.  Performance data is a bonus.

Just ask yourself.... With that liftoff tilt and that separation - even with separation motors - Do you think people should fly on that?
This test has almost no resemblance to Ares-I, thus nothing about it would affect my decision to fly on Ares-I or not.
If this test had no resembalance to Ares I, what was the test for?
Since people keep asking this, I guess a basic explanation is in order:

When you design a new vehicle, you build computer models. Lots of analysis is done on the computer models (structural analysis, computational fluid dynamics, thermal analysis, etc.) because it is cheaper, safer, faster, more convenient and therefore allows the study of various changes and options. This analysis is good, but not fully grounded in the real world. At some point, designers generally settle on a subset of their designs and build one or more wind tunnel models which are then put into a tunnel and tested as actual physical objects in actual moving air. Data gathered from the wind tunnel can then be folded back into the computer models to make them more accurate. A wind tunnel model is still not the "real thing" and is not operating in the actual flight environment, so the first full-scale vehicles of a given design are often instrumented to gather better data (Columbia was a good example of this) so that later production flight articles can be further optimized. Ares I-X was, in effect, a full-scale wind tunnel model for the study of first stage flight dynamics. Data from this first full-scale instrumented flight should provide data the shuttle designers did not have until STS-1 flew. It does not matter that I-X was not just like an Ares I; what matters is that it is just like the computer models and wind tunnel models of the I-X. The result will be to improve the models, which will then permit Ares I models to more closely match a future Ares I. The overall shape (engineers call it the "outer mold line" or "OML") of an Ares I should be close enough to that of the Ares, that the corrections to the I-X models will inform the Ares I models.

In addition, they probably generated a great deal of great strain gauge data, acoustics, data, etc.

Well done, to the entire Ares I-X team.

One of the folks brought up a good point about the launch - had it gone off yesterday, we would have lost it in the clouds and the way onboard video kept dropping out we wouldn't even know there was anything "interesting" happening at staging.

Q:  Took several days to launch Alan Sheppard... you guys were fast compared to that!  Ares 1, if cancelled, you need a year to lay plans, then 80 months to get to that.  How soon can we fly astronauts with Ares 1?

A:  Late 2016, early 2017, like Augustine said.  That timeframe is in reach.  2015 is still very achievable.

Q:  What would you say with "Ares V light"?

A: 80 months is typical development based on history.  It would take probably that long... 2017, 2018, 2019.

Looking at that HD version of separation, the upper stage seems to be given a shove from the lower stage which starts the tumbling.

The first two half-rotations for the upper stage take around 6 seconds each, with the next half-rotation (which is cut off just about halfway through) looking as if it's going to take a second or two longer - that would imply (to me) that the impulse which started the tumbling was not aerodynamic forces, but contact from the lower stage.

The issue (presumably) is made worse by the lower stage tumble motors firing whilst the upper stage is in too close a proximity to the upper stage - the cure for this would be slightly later firing of the tumble motors and possibly some method of slightly retarding the lower stage?

But the upper stage simulator doesn't start tumbling until about a second AFTER the first stage has swung past it. The separation motor fires at 2:03, I saw the tumble motor fire at 2:06, and given the angle I'd say the top of the lower stage goes past the base of the upper stage at about 2:07. The upper stage doesn't start tumbling until about a second later, in the 2:08-2:09 range.

RELEASE: 09-252

NASA'S ARES I-X ROCKET COMPLETES SUCCESSFUL FLIGHT TEST

CAPE CANAVERAL, Fla. - NASA's Ares I-X test rocket lifted off at 11:30
a.m. EDT Wednesday from NASA's Kennedy Space Center in Florida for a
two-minute powered flight. The test flight lasted about six minutes
from its launch from the newly modified Launch Complex 39B until
splash down of the rocket's booster stage nearly 150 miles down
range.

"This is a huge step forward for NASA's exploration goals," said Doug
Cooke, associate administrator for the Exploration Systems Mission
Directorate at NASA Headquarters in Washington. "Ares I-X provides
NASA with an enormous amount of data that will be used to improve the
design and safety of the next generation of American spaceflight
vehicles -- vehicles that could again take humans beyond low Earth
orbit."

The 327-foot tall Ares I-X test vehicle produced 2.6 million pounds of
thrust to accelerate the rocket to nearly 3 g's and Mach 4.76, just
shy of hypersonic speed. It capped its easterly flight at a
suborbital altitude of 150,000 feet after the separation of its first
stage, a four-segment solid rocket booster.

Parachutes deployed for recovery of the booster and the solid rocket
motor will be recovered at sea for later inspection. The simulated
upper stage, Orion crew module, and launch abort system will not be
recovered.

"The most valuable learning is through experience and observation,"
said Bob Ess, Ares I-X mission manager. "Tests such as this -- from
paper to flight -- are vital in gaining a deeper understanding of the
vehicle, from design to development."

Wednesday's flight offered an early opportunity to test and prove
hardware, facilities, and ground operations - important data for
future space vehicles. During the flight, a range of performance data
was relayed to the ground and also stored in the onboard flight data
recorder. The 700 sensors mounted on the vehicle provide flight test
engineering data to correlate with computer models and analysis. The
rocket's sensors gathered information in several areas, including
assembly and launch operations, separation of the vehicle's first and
second stages, controllability and aerodynamics, the re-entry and
recovery of the first stage and new vehicle design techniques.

The Ares I-X efforts are led by the Ares I-X mission management office
of the Constellation Program, based at NASA's Johnson Space Center in
Houston, and NASA's Exploration Systems Mission Directorate in
Washington. NASA's Glenn Research Center in Cleveland designed and
built the vehicle's upper stage mass simulator. NASA's Langley
Research Center in Hampton, Va., provided aerodynamic
characterization, flight test vehicle integration and the crew
module/launch abort system mass simulator. NASA's Marshall Space
Flight Center in Huntsville, Ala., with contractor support, provided
management for the development of Ares I-X avionics, roll control,
and first stage systems. The Kennedy Space Center provided operations
and associated ground activities and launch operations.

Contractors for Ares I-X include Alliant Techsystems, or ATK, of Salt
Lake City for the first stage solid rocket booster and Teledyne Brown
Engineering of Huntsville for the roll control system. Jacobs
Engineering of Tullahoma, Tenn., supported by Lockheed Martin of
Denver, provided the avionics systems. United Space Alliance of
Houston and ATK Launch Systems support the ground systems and launch
operations.

Since people keep asking this, I guess a basic explanation is in order:

When you design a new vehicle, you build computer models. Lots of analysis is done on the computer models (structural analysis, computational fluid dynamics, thermal analysis, etc.) because it is cheaper, safer, faster, more convenient and therefore allows the study of various changes and options. This analysis is good, but not fully grounded in the real world. At some point, designers generally settle on a subset of their designs and build one or more wind tunnel models which are then put into a tunnel and tested as actual physical objects in actual moving air. Data gathered from the wind tunnel can then be folded back into the computer models to make them more accurate. A wind tunnel model is still not the "real thing" and is not operating in the actual flight environment, so the first full-scale vehicles of a given design are often instrumented to gather better data (Columbia was a good example of this) so that later production flight articles can be further optimized. Ares I-X was, in effect, a full-scale wind tunnel model for the study of first stage flight dynamics. Data from this first full-scale instrumented flight should provide data the shuttle designers did not have until STS-1 flew. It does not matter that I-X was not just like an Ares I; what matters is that it is just like the computer models and wind tunnel models of the I-X. The result will be to improve the models, which will then permit Ares I models to more closely match a future Ares I. The overall shape (engineers call it the "outer mold line" or "OML") of an Ares I should be close enough to that of the Ares, that the corrections to the I-X models will inform the Ares I models.

In addition, they probably generated a great deal of great strain gauge data, acoustics, data, etc.

Well done, to the entire Ares I-X team.
Thanks, I would agree that this is a good explanation for the rationale behind the test. Since it seems likely Ares I will be dropped or at least modified, I think the test becomes even more of a success. NASA have proven for the first time that an SRB can be used as an unassisted 1st stage (ie without SSME assistance).

Another interesting point (at least to me) in the Q&A was about the differences in the launch countdown procedures for picking up the clock out of an open-ended hold...Atlas doesn't have the WX rule for "the T-word," so the significance of setting a time for resuming at T-4 didn't sink in as much as for this launch.  And as was pointed out I believe by Ed Mango, Shuttle count resumes are different.  (Something like a bit more than three seconds (http://forum.nasaspaceflight.com/index.php?topic=2078.msg51752#msg51752).)

First, I congratulate the entire 1-X team, lot of hard work paid off today.

However, I do have questions and will look forward to seeing the answers as the analysis comes out.

1.  At launch, the vehicle clearly has a tilt and the nozzle essentially kicks out toward the FSS.  For a second, I thought it was going to just keep going.  Obviously even with all that thrust behind you, the vehicle speed is till relatively small and other forces, such as wind, can have a large affect until those alphas and betas begin to converge.  Was that expected from either the GNC system or a wind loads perspective?

2.  The weather.  Were the LCC limitations intentionally strict due to it being a test flight or for other engineering concerns?  The shuttle could have launched and for all the billing of this rocket being simpler and safer, if the launch restrictions are tighter, than it will be ultimately more difficult. 

3.  Stage separation.  While the upper stage had "dynamics" that does not really mean much if separation occurred as designed since it was just going into the drink anyway.  It does look like there was some recontact and has the thrust transient at separation versus where the engine bell would be versus J-2 start time been evaluated and will this have any impacts on that?

Which begs the question, if they didn't need it for a more complex vehicle like the shuttle, why would they need it now and more importantly, spend 1/2 billion dollars on it.  The data is not worth that.  That is the cost of a planetary mission which would provide much more valuable data.

See, p. 69 (70 on adobe):

"While launch of the Orion on the Delta IV HLV was found
to be technically feasible, it requires some modification
of the current launcher, and was comparable in cost and
schedule to simply continuing with the development of
the Ares I. When the Committee factored in the carrying
cost of the NASA infrastructure that would be maintained
if any NASA-heritage heavy launcher would eventually
be developed (Ares V in any variant or a more directly
Shuttle-derived heavy launcher), any cost savings that
might have occurred due to using an EELV to launch the
Orion were lost. Using the EELV for launch of Orion
would only make sense if it were coupled with the development
of an EELV-heritage super-heavy vehicle for
cargo launch. Except in this case, this analysis closed out
the second option."

But the upper stage simulator doesn't start tumbling until about a second AFTER the first stage has swung past it. The separation motor fires at 2:03, I saw the tumble motor fire at 2:06, and given the angle I'd say the top of the lower stage goes past the base of the upper stage at about 2:07. The upper stage doesn't start tumbling until about a second later, in the 2:08-2:09 range.

I've spliced together a few images - http://i37.tinypic.com/s0vak1.jpg (http://i37.tinypic.com/s0vak1.jpg)

There's (limited) tumble of the USS from 2.06, which increases pretty rapidly to 2.09.

It may be the angle, but to my eye, it appears that the lower stage instigates the tumble of the USS.

What seems remarkable co-incidental is that the tumble of the two parts is perfectly co-ordinated in exactly the same way it would be as if there was contact.

Still, it's a pretty minor issue, which shouldn't detract from the overall massive success of the launch ;)

Very true, and something we all must keep in mind.

The driver says you'll get where you're going in an hour.  The traffic authority's consultant says you'll get there in 80 minutes.  There's still a lot of uncertainty in how bumpy the route is.  Every 10 minutes the traffic authority adds more fuel to the tank, but it may not be as much as they said they were going to add 10 minutes ago.  So maybe 80 minutes isn't even right.

Meanwhile, there's another bus in the barn, whose route is already paved.  Hell, it's electric - it consumes so little fuel comparatively.  It's only still in the barn because the traffic authority won't let it out.  There are even others who are willing to ride this bus and help decrease the fare.

In this case, I want the efficient bus with the paved road.  Spend the gas on the 18-wheeler that's moving my house so that I've got something to live in when I get to the end of the route.

There was some talk earlier about it tumbling but iirc there is an ares I animation showing an Ares I firing small side rockets near the base to intentionally swing away from the second stage.

I dont know if this one was set up for that but it looked like the animation Ive seen.

It could be that the SRB stage did NOT re-contact the USS, could just be from our POV it appeared that way, and the USS was just not stable enough to fly on its own.

Even if there wasn't recontact.. it appeared to stay in contact long after the Separation event.  Ullage motors are a must.. and this may tell them if they've planned for large enough motors

Ares I-X Using a 4-seg is not as high at sep and there may be more aerodynamic pressure on US than there will be at burnout for Ares I using a 5-seg Solid... although with 5-seg you'll also be moving faster at burnout..  Not sure what which case will be worse.

Is it not worth considering that the live upper stage on Ares 1 would have light off its own J-2x engine, and have GNC of its own? This would mean that the real vehicle would not suffer in this way?

AFAIK the J-2X engine will not fire immediately at separation, so any induced rotation on the US could be very problematic.

Remaining agnostic about the larger picture, but I'm glad the launch itself went well.

One short comment about the micro scrutiny evinced by the last 36 pages though. Can you imagine what it would have been like during the fraught testing of the early Deltas, Atlases and Titans in the 50s if a huge tribe of Nasaspaceflight fans were watching, in real time, every move? :)

I suspect that rocket testing remains the same, its the media technologies, and the audience's expectations, that have really changed.

Q:  Took several days to launch Alan Sheppard... you guys were fast compared to that!  Ares 1, if cancelled, you need a year to lay plans, then 80 months to get to that.  How soon can we fly astronauts with Ares 1?

A:  Late 2016, early 2017, like Augustine said.  That timeframe is in reach.  2015 is still very achievable.

Q:  What would you say with "Ares V light"?

A: 80 months is typical development based on history.  It would take probably that long... 2017, 2018, 2019.

I case anybody missed this...

I believe this is the FIRST 'OFFICIAL' announcement by NASA that their Ares-I schedule will definitely slip.

I'd hate to think how much money they honestly believe is required to improve Ares I & Orion development to make 2015.

As for their Ares V lite comment, 'history' of Ares-I alone would discount that timeline.

Forget the 50s -- there were Shuttle launch countdowns like this in the 80s and 90s.  I'm sure we would have examined ourselves a little too closely if the technology existed back then.

First, I congratulate the entire 1-X team, lot of hard work paid off today.

However, I do have questions and will look forward to seeing the answers as the analysis comes out.

1.  At launch, the vehicle clearly has a tilt and the nozzle essentially kicks out toward the FSS.  For a second, I thought it was going to just keep going.  Obviously even with all that thrust behind you, the vehicle speed is till relatively small and other forces, such as wind, can have a large affect until those alphas and betas begin to converge.  Was that expected from either the GNC system or a wind loads perspective?

Yes.  It was an avoidance maneuver designed to minimize pad damage and add clearance margin.  It looked aggressive because the rocket is nearly 100 meters tall.
Quote
2.  The weather.  Were the LCC limitations intentionally strict due to it being a test flight or for other engineering concerns?  The shuttle could have launched and for all the billing of this rocket being simpler and safer, if the launch restrictions are tighter, than it will be ultimately more difficult. 
Limits were due to range safety RF requirements for this vehicle alone.  It was a one-time deal.
Quote
3.  Stage separation.  While the upper stage had "dynamics" that does not really mean much if separation occurred as designed since it was just going into the drink anyway.  It does look like there was some recontact and has the thrust transient at separation versus where the engine bell would be versus J-2 start time been evaluated and will this have any impacts on that?

Ares I would have a different staging setup.  It would even separate at a different point. 

I think that the "recontact" claimed by some is an optical illusion caused in part by the extreme magnification of the tracking camera.  The fact that the first stage rotated past the upper stage simulator with no obvious change in the speed of either part supports no contact.  I also think that the successfully recovered first stage shows that it did not have contact.  If they recover the forward skirt extension (attached to the drogue chute) they will know for sure.  I'm not sure if that recovery is planned.

There was an oxidizer leak from one of the large flexhoses on the RSS hinge column that got smoked pretty good. We sent in a SCAPE team to fix it. Haven't been in there yet but the guys who went in said there was quite a bit more damage than a typical shuttle launch, and they've only seen up to the 95' level. Initial re-entry teams are in the pad now doing a walkdown.

Yes.  It was an avoidance maneuver designed to minimize pad damage and add clearance margin.  It looked aggressive because the rocket is nearly 100 meters tall.
Going back and looking at the west-pointing perimeter camera replay -- in which that maneuver is hard to see -- another interesting contrast is watching the booster track more or less straight up the FSS.  Versus Shuttles, which very distinctly translate north.  (Or left to right from the point of view of the same camera.)

With respect to the flex hose leak, I wonder if the Shuttle's normal "avoidance maneuver" helps reduce some damage to areas like that on the hinge line...

The Ares I-X flight looks like it performed, at the very least, to (most of?) the predicted simulations.  Very impressed with the flight. 

Minimal conclusion must be 'further development may make this (first stage SRB) an option for space flight'.

Watch it again in HD.  The USS doesn't begin to tumble until the yawing first stage swings to the right, after which it begins to yaw itself to the left at the same rate as might be expected by contact with something on the right side of its aft end.

It appears to me, that the separation event occurs, the stages begin to separate - cleanly, I will add - and drag on the USS causes it to begin slowing at the same time that tail-off from the first stage continues to impart a small residual acceleration.  Meanwhile, the first stage tumble motors impart the yaw, which then strikes the USS, causing it to begin tumbling in turn.

If the USS has accelerometer data I imagine whether this actually occurred will be discovered in short order.

Interesting info on L2 will follow I am sure. :)

Which begs the question, if they didn't need it for a more complex vehicle like the shuttle, why would they need it now and more importantly, spend 1/2 billion dollars on it.  The data is not worth that.  That is the cost of a planetary mission which would provide much more valuable data. 

I would imagine the data they were seeking with Ares I-X is probably not related to interplanetary unmanned spacecraft missions.

And yet the money spent on it could have financed one such mission.

I figure a lot of the data they were seeking in the I-X flight could have been extrapolated from Taurus.
http://www.orbital.com/SpaceLaunch/Taurus/

Though on a side note since Ares I-X did not CATO at max Q it might convince the congress critters to give them more money.

Though if they want to go with this vehicle they'll have to be more aggressive with their testing schedule and accept the fact a few will end up in the Atlantic.
The 2016 date might not be acceptable.

My point was that if the money that bought Ares I-X was spent on an interplanetary mission, then we would still be in need of a test launch. It may have been expensive, but it was needed. I can't see how it makes sense to argue both in favor of manned exploration, and spending the Ares I-X cash on an interplanetary mission. NASA is already doing interplanetary missions and has plenty going on. Before today, NASA never had an Ares test launch. IMHO, spending the cash to fly Ares I-X was wise, under the Constellation Programme architecture (whether or not Constellation itself is a wise choice notwithstanding).

This will be one of the video stills to examine closely in HD, to see if any impact damage is apparent.

I'm still not seeing it (impact).  These are two massive, heavy objects, hurtling through the upper atmosphere.  If they had smashed into one another, I would have expected debris of some type flying off from an impact of that size, etc.

It doesn't quite look like recontact to me - more like the stages had not completely separated as the thruster fired to start the rotation. To my eye it seemed like the leftover thrust from the SRB was still stronger than the retro's, so the retro's were not as effective as they should have been.

With the two having low relative velocities, maybe it's possible they can hit without making a mess? Just sort of bump and gently shove each other?

ATK's First Stage Successfully Launches NASA's Ares I-X Flight Test
Culminating Four Years of Progress, Historic Test Demonstrates Long-Term Strategic Architecture, Unmatched Crew Safety
Flight Test Critical First Step to Launching NASA's Future in Human Spaceflight

MINNEAPOLIS, Oct. 28 /PRNewswire-FirstCall/ -- Alliant Techsystems' (NYSE: ATK) first stage ignited today at 11:30 a.m., launching the Ares I-X flight test for NASA and igniting the next generation in American spaceflight. The Ares I is designed to be the safest rocket ever developed to deliver humans to space.

"The successful launch of the Ares I-X continues to demonstrate decades of flawless performance and the progress ATK and NASA have made to develop the most reliable and affordable family of solid rocket motors ever produced," said Blake Larson, ATK Space Systems president. "This flight provides critical data that can be tested only in a flight environment and will be a key building block for maturing the design of Ares I and developing Ares V."

The 177-foot-tall, 12-foot diameter first stage produced 3.3 million pounds of thrust to propel the vehicle from liftoff to stage separation 124 seconds into the flight. At 130,000 feet, the first stage parachutes deployed, enabling the spent booster to slow its descent prior to splashing down into the ocean where it will be recovered for reuse.

"This flight test is the culmination of four years of progress and is the critical first step to launching America beyond low earth orbit, signifying the beginning of a new era for the American space program," said Mike Kahn, ATK Space Systems executive vice president. "The Ares I architecture provides unmatched crew safety and performance for payload capacity, all while utilizing existing infrastructure."

The primary test objectives for the Ares I-X flight included demonstrating vehicle proof of concept, and vital flight performance early in design of the Ares I program. It also demonstrated effective vehicle integration, ground processing and launch operations.

The flight test of the Ares I-X brings America one step closer to the goals of sending humans beyond low Earth orbit for sustained exploration of multiple destinations throughout the Solar System. The launch is a critical milestone in the development of NASA's Constellation Program, which will also support missions to the International Space Station.

The Ares I-X First Stage is comprised of a four-segment Reusable Solid Rocket Motor (RSRM) originally produced for the Space Shuttle Program, and newly designed hardware including the frustum, forward skirt extension, forward skirt and a simulator representing the fifth segment that will fly on the Ares I vehicle. The solid rocket motor cases used for Ares I-X have collectively flown on 30 previous shuttle missions and will continue to be reused for the Ares program. The solid rocket motors were produced at ATK's facility in Promontory, Utah, and the new hardware was manufactured by Major Tool and Machine Inc. in Indianapolis, Ind., under a contract to ATK.

ATK and NASA have continually improved their techniques and processes to increase the safety and mission reliability of the RSRMs. These motors have undergone countless subscale material characterization tests that tie together complex analyses with hard data. They have also undergone 27 full-scale ground tests, including a successful test of the Ares I first stage five-segment development motor conducted last month.

ATK is the prime contractor for the first stage five-segment solid rocket motor and provides the main abort motor and attitude control motor for Orion's Launch Abort system.

I have to think a Falcon 1 flt 2-class recontact wouldn't create much debris. Flt 3's recontact might have been more benign if they could have stopped the second stage engine from starting.  Not that that would've done any good. I have to say, despite my general antipathy to Ares I, this launch looked very cool. Wish I could have seen it in person!

Yeah, that's why it's called recontact and not resmash  ;)
Not saying I believe there was any contact, but not dismissing it either.

All these camera angles are only just tentatively suggestive. I wish there was a more sideways look angle from one of them chase planes if only they were used... what were they, WB-57?

That was my thought.  To me it looked like what I'd imagine if a cord or cable was still attached between them, or if the releasing system did not finish the seperation when the thruster fired, whipping the USS around.

I have a question about the separation event - Let's say the two stages DID recontact one another.  If this had been an actual Ares I launch, what would have happened?  Would the J2-X abort operation and could the LAS save the crew if the upper stage started tumbling like that?

Congrats to NASA on their launch of Ares 1-X!  I watched it this morning on NASA TV and it was one of the most spectacular launches I have watched.  I got nervous when the rocket appeared to lean quite a bit as it lifted off but she flew very well once airborne. 

I agree that there was definitely some funny business going on during stage separation.  I'm curious what NASA will conclude after reviewing the footage and data.

For number 1, I would like to see that documentation, because everything I have seen shows that "event" not taking place.  I have seen estimates for when umbilicals will separate, the hold down posts will break, first expected motion, roll but nothing about this "planned maneuver"

For number 2, I would like to see that documentation as well.

For number 3, I would like to see that documentation as well.  It very well may but certainly recontact was considered in this conops.

Aren't there only two more test flights scheduled?  (I-Y and Orion 1)

Wasn't I-Y cancelled? 

In fact, in the news conference Handley (I think -- I was just listening to the sound) said something about possibly adding a J-2X to the Ares I-Y flight...
I could not find it on NASA's site but yes indeed Handley worked up a mitigation schedule listing a number of Orion and Ares program requirements that could be dropped to buy some of the gap back. One of those were to forgo Ares 1Y and move straight to a complete integrated launch including an Orion and working LAS. (unmanned)

Since Ares 1x staged at a lower altitude with more atmosphere, is it possible that yes indeed the retro rockets were not powerful enough but that there was no actual contact made between the FS and USS but rather when the FS swung around it was so close that it washed out the USS? Actually moved enough surrounding atmosphere to kick USS's orientation?

Apologies if this is completely out of the question.

1.  My point was that if the money that bought Ares I-X was spent on an interplanetary mission, then we would still be in need of a test launch. It may have been expensive, but it was needed.

2.   I can't see how it makes sense to argue both in favor of manned exploration, and spending the Ares I-X cash on an interplanetary mission. NASA is already doing interplanetary missions and has plenty going on.

1.  no, the point is that a test launch wasn't required.  Especially at this cost and the marginal data.  The shuttle didn't need a test launch.

2.  No, Constellation has been taking away from the unmanned program.  There are no east coast unmanned launches in 2010

Would the J2-X abort operation and could the LAS save the crew if the upper stage started tumbling like that?

The LAS would have gone off after the stage went out of limits within 5-20 degrees

It could be that the SRB stage did NOT re-contact the USS, could just be from our POV it appeared that way, and the USS was just not stable enough to fly on its own.

Even if there wasn't recontact.. it appeared to stay in contact long after the Separation event.  Ullage motors are a must.. and this may tell them if they've planned for large enough motors

Ares I-X Using a 4-seg is not as high at sep and there may be more aerodynamic pressure on US than there will be at burnout for Ares I using a 5-seg Solid... although with 5-seg you'll also be moving faster at burnout..  Not sure what which case will be worse.

Is it not worth considering that the live upper stage on Ares 1 would have light off its own J-2x engine, and have GNC of its own? This would mean that the real vehicle would not suffer in this way?

I pointed that out earlier...but people here need to find SOMETHING to nitpick about on an otherwise successful flight. ;)

A number of the same posters also nitpicked the last SpaceX flight...

First, I congratulate the entire 1-X team, lot of hard work paid off today.

However, I do have questions and will look forward to seeing the answers as the analysis comes out.

1.  At launch, the vehicle clearly has a tilt and the nozzle essentially kicks out toward the FSS.  For a second, I thought it was going to just keep going.  Obviously even with all that thrust behind you, the vehicle speed is till relatively small and other forces, such as wind, can have a large affect until those alphas and betas begin to converge.  Was that expected from either the GNC system or a wind loads perspective?

Yes.  It was an avoidance maneuver designed to minimize pad damage and add clearance margin.  It looked aggressive because the rocket is nearly 100 meters tall.
Quote

Ares I would have a different staging setup.  It would even separate at a different point. 

I think that the "recontact" claimed by some is an optical illusion caused in part by the extreme magnification of the tracking camera.  The fact that the first stage rotated past the upper stage simulator with no obvious change in the speed of either part supports no contact.  I also think that the successfully recovered first stage shows that it did not have contact.  If they recover the forward skirt extension (attached to the drogue chute) they will know for sure.  I'm not sure if that recovery is planned.

 - Ed Kyle

The tilt in the beginning wasn't to minimize pad damage it was to prevent contact with the tower. If anything it was the best trajectory to maximize pad damage. I can't wait until the SCAPE guys hose it down so we can go out and look.

We are trying to get them to fly the other way on ARES I to minimize pad damage. Aiming the dangerous end at the tower the first 5 seconds doesn't make us GSE guys happy.

And a good number of people here are actual engineers.  Looking for things that went wrong (or just "less right") is part of the job.  It's not personal, and it's not gloating over someone else's failures. 

Picking over the available data for things to learn is just good engineering and a sign of a skeptical, engaged mind.

IMO. :)

I'm going to reply to several things here, all piled together, NSF needs multiquote capability :)

All these camera angles are only just tentatively suggestive. I wish there was a more sideways look angle from one of them chase planes if only they were used... what were they, WB-57?

This question came up in one of the pre-flight pressers, and I'm trying to remember the exact answer.  I think it was that they would be only looking for parachutes, not separation event.

(and hello ugordan, I'm a big fan of your imagery work at UMSF!)

"Since Ares 1x staged at a lower altitude with more atmosphere, is it possible that yes indeed the retro rockets were not powerful enough but that there was no actual contact made between the FS and USS but rather when the FS swung around it was so close that it washed out the USS? Actually moved enough surrounding atmosphere to kick USS's orientation?

Indeed, hours ago someone suggested here that it could be "proximity aero", which is the best idea I've heard yet.

"In fact, in the news conference Handley (I think -- I was just listening to the sound) said something about possibly adding a J-2X to the Ares I-Y flight...

Hanley said this in one of the pre-flight pressers too.  Several Ares folks have been saying publicly for a while now that they do want to get a real engine on Ares 1-Y, it's "just" a matter of getting the J-2X and 1-Y schedules to line up.

AND THAT is just what I gathered in the past three days of catching up with the HSF business.  Been busy with non-space stuff.  (gasp!)

The tilt in the beginning wasn't to minimize pad damage it was to prevent contact with the tower. If anything it was the best trajectory to maximize pad damage. I can't wait until the SCAPE guys hose it down so we can go out and look.  We are trying to get them to fly the other way on ARES I to minimize pad damage.

Very interesting, thanks for the insight!

Agreed.  While I see the reference to this being a planned maneuver, this seems like it could be bad practice to have your launch vehicle thrust semi-directly at your launch infrastructure every time you launch it.  Certainly will drive up maintenance costs and presumably this would be something that would be considered on any operational vehicle like Ares 1, regardless of what the tower looks like then or where it located relative to the vehicle.

In addition, if I were a crew member, not sure how I would feel about such a long and skinny vehicle doing this intentionally with such low amount of foward momentum.

Yes.  It was an avoidance maneuver designed to minimize pad damage and add clearance margin.  It looked aggressive because the rocket is nearly 100 meters tall.

For number 1, I would like to see that documentation, because everything I have seen shows that "event" not taking place.  I have seen estimates for when umbilicals will separate, the hold down posts will break, first expected motion, roll but nothing about this "planned maneuver"

While I've seen no *internal* documentation, the tower avoidance maneuver was reported in the press at the time of rollout:

http://spaceflightnow.com/ares1x/091020pad/

"We've designed a flyaway maneuver for the nozzle to cant over ever so slightly -- 1 degree -- not that much to us, but with 2 million pounds of thrust, that's going to take the vehicle and help it to fly away from the pad," Stelzer said.

Stover said engineers predict there will be about 15 feet of clearance between the pad and the rocket at liftoff, so there is no threat of physical contact. Officials are only concerned about the affects of the booster's plume.

2.  The weather.  Were the LCC limitations intentionally strict due to it being a test flight or for other engineering concerns?  The shuttle could have launched and for all the billing of this rocket being simpler and safer, if the launch restrictions are tighter, than it will be ultimately more difficult.
Limits were due to range safety RF requirements for this vehicle alone.  It was a one-time deal.

For number 2, I would like to see that documentation as well.

Again, while I've seen no internal documentation, this was discussed at today's press conference. Ares I-X has triboelectrification restrictions because NASA decided that the efforts to mitigate it weren't worth it for a one-off vehicle.

5-segment SRB will be higher (therefore lower q) at separation than the 4-segment SRB used for Ares I-X.

Ares I upper stage will have ullage motors that the Ares I-X upper stage simulator lacked. These motors are used to assist separation as well as settle the propellants.

http://spacefellowship.com/2009/07/01/atk-awarded-contract-for-ares-i-upper-stage-ullage-motor/

While neither of those guarantees no recontact, it does mean the conditions will be different at sep.

It's a tradeoff. Without a tower avoidance maneuver, the allowable winds at liftoff would have to be reduced.

Also keep in mind that the shuttle legacy FSS/RSS won't be there by the time Ares I flies. The FSS was "hardened" for Ares I-X but only a limited amount of hardening makes sense for a structure that's going to be demolished anyway. The Ares I ML can be hardened with the tower avoidance maneuver in mind.

In addition, if I were a crew member, not sure how I would feel about such a long and skinny vehicle doing this intentionally with such low amount of foward momentum. 

The Apollo astronauts would tell you to man-up. The Saturn V also performed a tower avoidance maneuver and it also lifted off very slowly. It is not obvious in many launch photos due to camera placement but it shows up really well in some of them:

On May 5, 1961, Alan Shepard was launched suborbitally to an altitude of over 116 miles, 303 statute miles down range from Cape Canaveral. His 15 minute 28 second flight achieved a velocity of 5,134 miles per hour and pulled a maximum of 11G's.2

Glad I got to see the launch before going to bed in the middle of the day....

Congratulations to the team.  Good work. 

That second stage separation didn't look right, but we'll see what the engineers say about that.  Where did the USS land?  And did the dent on the nozzle that OV-106 talked about come from a hard landing (one parachute failed?) or striking something on the MLP/pad?

When the bird launched and went off to the right I thought "uh oh" but turns out that was the planned tower avoidance manuever.  Flight looked spectacular.

And thanks to the two Chris's and everyone else for the coverage.

From what I've gathered from the damage reports it seems that the area around the hinge column took the brunt of it. Majority of damage and debris is from that area. Alot of damage such as loose/damaged grating on the 95' level, but that level always looks like a train wreck after every launch. Catches all of the blast deflected from the MLP zero level. Incidentally the damaged hyper flexhoses were on that level of the hinge column.

Don't like the fact that the avoidance maneuver directed alot of blast at the tower, but I'll take some tower damage over a destroyed vehicle/tower anyday.

A "normal" upper stage doesn't get to be on its own until it's well out of the atmosphere.  Because Ares-I's first stage is so weak, it's upper stage gets to fly while there still is significant q.  If there was no recontact, doesn't the performance of the upper stage simulator indicate that's it's pretty severely aerodynamically unstable?  If so, could it gain some fins to assure the upper stage guidance has both sufficient authority and sufficient time to use that authority after separation?

Depends on how much and how soon the money flows. Still some decomissioning/safing and spares removal to get done. MLP 1 is supposed to be scrapped, but again, if the money is there.

Now, whenever the funding shows up, rollercoaster construction can begin, remove the slidewires and bunker, finish the lightning protection, start dismantling the FSS/RSS, (hopefully a refurbishment/mod period for LH2?), and many other jobs/construction that I can't think of right now.

Geesh, I actually agree with Jim on this one, go figure LoL!)
But at least a real launch has more of a WoW factor for the general public to it than some silly moon bombing thing!

Wondering about a few things if anybody cares to enlighten:

-Does the seperation "glitch" give more credence to the 45th's original preliminary assertion about crew survivability & that it's still unproven in apparently the models as well as this "wind tunnel" test (wasn't that the whole justification for the Ares design)?

-Read somewhere of a report that the recovery ship found a gash in the 1st stage? Also, differing reports about whether 2 or 3 chutes deployed - there seemed to be enough aircraft & ships around viewing - shouldn't there be some pics released?

-Pad leak & damage, will pics & repair costs be released? Or doesn't it matter because of need to reconfigure anyway?

-The lightening strikes - what, if anything, did the new lightening towers contribute (i.e. worked better or worse than the old system)?

-Seemed like a lot of unusual comm/data drops - any indications of root cause forthcoming?

Thanks!

No, at least not yet.  Last I heard was that it's scheduled for September 2012, but according to information listed earlier today, changes to the test objectives could push it two years to the right.

From what I've gathered from the damage reports it seems that the area around the hinge column took the brunt of it. Majority of damage and debris is from that area. Alot of damage such as loose/damaged grating on the 95' level, but that level always looks like a train wreck after every launch. Catches all of the blast deflected from the MLP zero level. Incidentally the damaged hyper flexhoses were on that level of the hinge column.

Don't like the fact that the avoidance maneuver directed alot of blast at the tower, but I'll take some tower damage over a destroyed vehicle/tower anyday.

I'm guessing that the "hinge column" is the pivot point on the tower for the RSS?  just curious

OK.. attempting to defuse this.....

I get your point. I should have clarified myself. I was not trying to imply that this is NASA's finest moment, or in the top 10, 20, 100, whatever.. I was just getting a little frustrated at the number of posts on here, like the majority of yours have been today, that hint to today being a total failure and a complete waste of money. You've made it quite clear in the past that you are not an Ares fan and I understand that. And to reiterate what I'VE said in the past, I'm not a huge Ares fan myself. But I will give credit where it is due and NASA proved today that there is some credibility to the Ares I design, as close as I-X could have been to the actual Ares I. Were there problems, yes. Did the rocket brush the tower, possibly. Did the two stages bump/collide, possibly. Did a chute fail, possibly. (I'm saying possibly because I haven't heard anything concrete yet.) Did this flight show problems that need to be addressed, sure. But, as I've said earlier today, this is a TEST FLIGHT! If problems are going to manifest themselves, this is the time and place for it. Yes, computer modeling is a wonderful thing, but sometimes it just helps to have real world data.
   Now would I have rather seen the money used for other things, of course. But when the money was spent, contracts were finalized and the ship was built, I would have rather seen it flown than scrapped. Will it come to be that this was a complete waste of time/money? Of course that's possible. For all we know this could be the only flight Ares makes. But I do also think it may have been a good idea to kind of put NASA back on the radar of certain individuals that seem to always have other things to attend to. I happen to love my job and love what I do. I would work here for half of what I make now. And I would still happily work here if it was on shuttle, Ares I, Direct, EELV, HLLV, Shuttle C, "Not" Shuttle C, Ares V, Ares V "lite", Ares IV, etc. I don't care. I would just like SOMEONE to make a decision so I know if I might have a job in two years. So if this was a PR stunt like some think, so be it. I hope it has the effect that we need right now. Rant complete.

P.S. Jim, give me a hug man, you know you want to...

Will it come to be that this was a complete waste of time/money? Of course that's possible.

The analysis of the staging deviance from modelling will be applicable to any future new NASA rocket design. TO/Acoustics data will be useful for any SDLV. Roll Torque data will help any future commercial SRB first stage designs like Athena variants. So it might be possible it's a complete waste of time and money but extremely unlikely ;). The other thing is credibility, it gives NASA very visible post-Shuttle credibility with the public and politicians and that can only help with getting more funds from the President and Congress. Jim just has to look at the bigger picture and see that his section too will ultimately benefit from association with this.

Lee Jay, I suspect you might be right, especially after checking out klausd's video above.  Like most people, my initial reaction at separation was recontact had caused the 2nd stage to tumble, but now on further review I'm not so sure.  One thing is for sure, if Ares does fly again the 2nd stage aerodynamics are gonna need some refining...

In a related thought, would it be possible to get relevant data from a 1/8th or even 1/4 scale replica, perhaps baloon launched to get to altitude?  You would think it would be many times more cost effective at maybe just a few mil per copy so you could fly quite a few trials for a lot less expense.  It might be a reasonable way to look at separation dynamics.  Heck, you could even call it Ares 1/X...:)

I have been waiting for months for the event you can admire in the video and nothing till now. People who claimed to have built that strange rocket is keeping delaying the launch. I suppose they will never launch the rocket.

Post by: Zoomer30 on 10/29/2009 03:17 am
I really doubt the rocket hit the tower, cant see how it could have and still flown stable, or at least not without taking a good chunk of the tower with it.  The "fly away" move should have taken the tower out of the equation.  As for the stage sep, I dont think there was contact, from our odd angle of view it may have looked like it, more than likely just aerodynamics.  Sorta like two NASACAR racers in a tight draft, when the front one pulls away it gets hit with more turbulence. 

Hopefully on the full Ares I they will have the umbilical hook up either in the very front or very back, so all the arm has to do is swing away, so even if the rocket came back towards the tower and still would not hit the arms.

The program wont be scrapped, that much is clear, its here to stay.  The fact that they are spending all this time and money building a new MLP and LUT should make that clear to even the most jaded among us.

"I think it was September 2013 originally...but 2014 is the more likely date as you mentioned "

After today's launch I find myself wondering when the next Ares launch will be and oddly looking forward to it though I have eagerly followed the shuttle since I was a kid, and haven't been thrilled about the stick's problems (schedule slips, taking stuff out of Orion, etc.).  5 years is a long time to wait.  I remember seeing something on this forum about an "Ares I-X Prime" with a full 5 segment booster and a LAS abort test, could the program work that in for 2011-12 (I know depending on money)?  And would the current SRB being retrieved in the Atlantic be refurbished and sent back for the next Ares launch, if the program lives?

They could even use this vehicle to launch re-supply vehicles (like Progress or like that thing Japan has).  It has a lot of uses and uses stuff that they have been working with for 30 years (the J2X is basically a J2 and the SRB is old hat to them)

All I can say is from reading this board today its a good thing we did not have the Internet or the Web in the 60s, NASA would have gave up on the Moon if they had to take grief for every test flight they ran.

We need this system, ironically the shuttle is too expensive to use for what was its PRIMARY mission when developed:  Fly to a space station (in fact one of the first STS missions was going to be a Skylab rescue mission). 

We need something like the Russians have, a good cheap ship that gets us for point A to point B and back.  No sense in driving the Porsche down to the local store for food when the Citation will do just find.

A "normal" upper stage doesn't get to be on its own until it's well out of the atmosphere.  Because Ares-I's first stage is so weak, it's upper stage gets to fly while there still is significant q.  If there was no recontact, doesn't the performance of the upper stage simulator indicate that's it's pretty severely aerodynamically unstable? 

The Ares I-X staging altitude was about the same as a Proton's first stage jettison altitude (40 km versus 42.5 km).  The staging velocity is in the same ballpark (1,488 m/s versus 1,797 m/s).  Proton is considered "normal" enough.  It's flown 348 times, and more times this year than any other commercial comsat launcher.

Ares I will stage higher (nearly 60 km) and faster (~2,000 m/s) than either Ares I-X or Proton.  (Ares I staging will occur at roughly the same altitude as Saturn IB - a rocket that worked pretty well.)  The Ares I first stage will also produce 1.25 times more total impulse than a Proton first stage, and 1.6 times more than a Saturn IB booster stage.  Hardly "weak".

Anyways, back to topic.  It's an understatement to say that the U.S. needs something that's efficient (and simple?) like the Soyuz.  Ares doesn't look as elegant as the shuttle, but judging from today's launch, making the right refinements to the design here and there and receiving proper funding should give the U.S. a vehicle that's on the same level of reliability as the Russian's launch system.

Not to state the total obvious.

Orion was not designed to do what Soyuz does (LEO taxi work for three Cosmonauts).  It was designed to go to the Moon while carrying more than three astronauts.  Building nothing but a micro-LEO crew ship like Soyuz would keep the U.S. in LEO indefinitely.  It would mean not going to the Moon.

The customer considers AV-9 a success.  It's not a vehicle, it's a culture.  The Shuttle culture knows sustaining and cost-plus bloat where you can't even have a conversation about cost v. safety to send back a costly solution for an equally safe but cheaper one.

According to this table:
http://en.wikipedia.org/wiki/Comparison_of_mid-heavy_lift_launch_systems

An ATLAS V rocket can place a payload of 20 000 kg in LEO for a cost of 164 mil dollars.

A cargo moon craft with the total mass of 40 000 kg would cost 328 mil + the cost of the spaceship itself.

A Soyuz capsule launched in LEO with a crew of three could be 100 mil $, fully equipped. A lunar lander and return to moon orbit could be 300 mil $.

That cargo ship of 40 000 kg could cost 300 million itself (only the part that does not constitute lander)

So if we add all the costs, a moon mission might cost:

328 mil $ - to lift to orbit 40 000 kg of payload
300 mil $ - the payload itself (without the lander)
100 mil $ - the crew capsule
300 mil $ - the lander (the mass of the lander is included in those 40 tonnes of payload)
-----------------------------
1028 mil $ - a Moon mission!

Will such a mission be cheaper using ARES?

Well, with some additional funding and luck, we might just have that. Before Ares-1 flies, even. And quite a bit cheaper.

I am referring to the other (commercial) capsule in development right now.

I'm sure NASA can get the Ares I to work. The question is if it will be worth the expense.

Aren't bow shocks generated in front of an object traveling supersonically? I.e. a higher pressure region *some distance* in front of the front end of the SRB? If so, what if one side of the USS aft end dipped into this region? Don't know much about fluid dynamics, just wondering if that's possible here.

Either way, looking at klausd's video at 50% speed it's pretty clear the booster deceleration motors didn't give enough kick to the SRB because they only made it clear the USS by a finite distance at which point I assume residual thrust nulled out the separation rate and the two stayed at about the same fixed distance (or worse, started approaching each other).

Post by: MKremer on 10/29/2009 09:02 am
We'll have to wait to know for sure - if the forward SRB section shows anything, and the data verifies any contact.

Right now, though, having seen a number of HD and slow motion video replays of the separation, I don't believe there was any contact.

It looked to me like there may have been some off-center forces from the separation event, and once the US started rotating from that, aerodynamic forces quickly took over and rapidly accelerated the rotation. It was just coincidence that the booster stage rotation happened to match almost identically while they were still relatively close to each other.

Which of course means that if you're flying vertically (as is the case after liftoff) you in fact need and average T/W ratio of 2.1 G.

Either way, looking at klausd's video at 50% speed it's pretty clear the booster deceleration motors didn't give enough kick to the SRB because they only made it clear the USS by a finite distance
You were expecting the FS to be separated from the USS by an infinite distance?  ;)

We need this system, ironically the shuttle is too expensive to use for what was its PRIMARY mission when developed:  Fly to a space station (in fact one of the first STS missions was going to be a Skylab rescue mission). 

We need something like the Russians have, a good cheap ship that gets us for point A to point B and back.  No sense in driving the Porsche down to the local store for food when the Citation will do just find.

How cheap is Soyuz (LV and capsule) really? If the US had proceeded with the original Saturn I (with the kerolox second stage), and had flown something like a Big Gemini on top of it, how cheap would it be now?

The program wont be scrapped, that much is clear, its here to stay.  The fact that they are spending all this time and money building a new MLP and LUT should make that clear to even the most jaded among us.


That is not true.  It will likely be scrapped if the President acts per Augustine Commission.

As for building hardware, that doesn't mean anything, see X-33.

They could even use this vehicle to launch re-supply vehicles (like Progress or like that thing Japan has).  It has a lot of uses and uses stuff that they have been working with for 30 years (the J2X is basically a J2 and the SRB is old hat to them)


No, EELV's would be cheaper.  Ares I has one use only, to launch Orion.

Ares I will stage higher (nearly 60 km) and faster (~2,000 m/s) than either Ares I-X or Proton.  (Ares I staging will occur at roughly the same altitude as Saturn IB - a rocket that worked pretty well.)  The Ares I first stage will also produce 1.25 times more total impulse than a Proton first stage, and 1.6 times more than a Saturn IB booster stage.  Hardly "weak".


It still doesn't matter, the delta V split for Ares I is not optimal.

Nor would the split be optimal for an EELV, unless a higher thrust upper stage were developed.

No it isn't.  It would require a development effort that wouldn't necessarily be cheap, but I guess that's a relative term if it cost us $400+ million to get to yesterday's launch.  It would be a lot less than that to re-establish the dual engine capability on Atlas/Centaur.

Vehicle Cam 1 proved no good for staging, lost signal right at staging.

Interesting trick there, I would say! One transmitter for 2 cameras.

What we see as "Cam 1" is in fact video signal from two different cameras.

Before staging, video came from the camera on the frustum, looking down.

After staging, video auto switched to the camera on 5SS (fifth segment simulator), looking up.

Let's also note that it took billions to get to this point, not just $400 million.  $445 or so is just for costs associated with launching this specific hardware, which as we all know shares almost no commonality with Ares I other than exterior dimensions.  Ares I has churned up billions and will continue to churn of tens of billions more if we choose to let it.

A "normal" upper stage doesn't get to be on its own until it's well out of the atmosphere.  Because Ares-I's first stage is so weak, it's upper stage gets to fly while there still is significant q.  If there was no recontact, doesn't the performance of the upper stage simulator indicate that's it's pretty severely aerodynamically unstable? 

The Ares I-X staging altitude was about the same as a Proton's first stage jettison altitude (40 km versus 42.5 km).  The staging velocity is in the same ballpark (1,488 m/s versus 1,797 m/s).  Proton is considered "normal" enough.  It's flown 348 times, and more times this year than any other commercial comsat launcher.

Ares I will stage higher (nearly 60 km) and faster (~2,000 m/s) than either Ares I-X or Proton.  (Ares I staging will occur at roughly the same altitude as Saturn IB - a rocket that worked pretty well.)  The Ares I first stage will also produce 1.25 times more total impulse than a Proton first stage, and 1.6 times more than a Saturn IB booster stage.  Hardly "weak".

Thanks Ed for answering a good question?

I have worked on numerous NASA GSFC missions.
Developed UARS for STS-48 launch and a 15 year mission.
The UARS program  -- $750,000,000
  under budget and on schedule.

NASA doesn't have unlimited funds!!

Please,  it NOT nonsense!!!!




$450,000,000  for this test
Can someone show me the pieces that added up to the total?

If this is "Nothing like Ares-1" (for manned flight) then what is it for?

 Will there be an all up unmanned launch of Ares-1?
 What will that cost?

This is cheaper than STS flights?



On May 5, 1961, Alan Shepard was launched suborbitally to an altitude of over 116 miles, 303 statute miles down range from Cape Canaveral. His 15 minute 28 second flight achieved a velocity of 5,134 miles per hour and pulled a maximum of 11G's.2

The UNMANNED 327-foot tall Ares I-X test vehicle produced 2.6 million pounds of thrust to accelerate the rocket to nearly 3 g's and Mach 4.76. It capped its easterly flight at a sub-orbital altitude of 150,000 feet after the separation of its first stage and splashed down nearly 150 miles down range.

Seems little progress has been made in 48 years

Nonsense.  Please.  Just stop.

It's an understatement to say that the U.S. needs something that's efficient (and simple?) like the Soyuz.  Ares doesn't look as elegant as the shuttle, but judging from today's launch, making the right refinements to the design here and there

What exactly did you judge from today's launch? I only saw the proof of the already known aerospace truth that if you push anything hard enough, it will fly.

and receiving proper funding should give the U.S. a vehicle that's on the same level of reliability as the Russian's launch system.

That would most likely be from the the impact with the pad that looks like happened from the "tilt" question I posed earlier.  In addition I hear the nozzle has a dent. 

How would they know if the nozzle has a dent? The SRB nozzle extension is separated just prior to splashdown and is not recovered.

NASA have proven for the first time that an SRB can be used as an unassisted 1st stage (ie without SSME assistance).

Well, actually the Minuteman ICBM, first flown in the early 1960s, has an unassisted SRM for the first, second and third stages.  Granted, at 60 feet, it's rather much smaller than ARES, but it's still no slouch of a rocket.

The last 1B put 16,700 kg into a 140 mile orbit.  (sorry to mix systems there)  Ares is supposed to put 25,000 kg into LEO, and I assume that means to the ISS which would make the power difference even more remarkable.  (sorry if my figure for Ares mass to the ISS is off, I don't have a mind for the minutia like some here do.)

Not something that has to be broken down into its constituent parts and essentially remanufactured between flights.

I like Soyuz a lot, and Saturn even more, but while the 1B was (is) much more powerful than the Soyuz, and the planed upgrades (single F-1/F-1A on the LS, reducing the tanks from 9 to 2, dropping the 8 fins, and using the J-2S on the upper stage) would have made it even more powerful, the Ares is supposed to be yet even more powerful for the same (or even less?  Hmmmm) cost as Soyuz.  And that's about the most gracious thing I've ever said about da stick. 

The last 1B put 16,700 kg into a 140 mile orbit.  (sorry to mix systems there)  Ares is supposed to put 25,000 kg into LEO, and I assume that means to the ISS which would make the power difference even more remarkable.  (sorry if my figure for Ares mass to the ISS is off, I don't have a mind for the minutia like some here do.)
I have been thinking on this some as well.  The Ares I, when built, will have a re-usable first stage.  Not too bad an idea, actually.  if we had a way to re-use the 2nd and crew stage, would be a full RLV.

I wasn't talking about 1B, I was talking about original Saturn 1, which had 6x RL-10 upper stage, and particularly the unbuilt original proposal, with a kerolox upper stage. I also have some question about calling the RSRM "reusable." When we talk about RLVs, we generally talk about something that essentially needs some repair, followed by refueling, to be reused. Not something that has to be broken down into its constituent parts and essentially remanufactured between flights.

I only cited the 1B as a way of making the point that these early class of rockets - the Soyuz and the comparable Saturn I - and the much, much more powerful Saturn 1B are still not in the power class of the Ares I. 

But I guess that's the $10 billion ($40 billion?) question.  How much power does one really need?  Clearly, just to get three bodies to the ISS all you need is Soyuz. 

But, IMO, if a new motor were to be invested in, then the five seg SRM is a dud and dead end.  I'd echo the comments of Larry Williams of SpaceX:

Quote from: Larry Williams
“If we had the F-1 back, that would be a game-changer, in my opinion, in terms of cost of access to space.” That could be done, he said, for “a relatively small investment” spread across several agencies.

And that would allow a series of rockets with many varieties of capabilities, instead of the fixed capacity the Ares I locks NASA into.

The same pictures and two more are also in Todd Halvorson's (FloridaToday) last "Flametrench" post. He's also referring to internal E-Mails that he obtained, which indicate that only one of the three parachutes deployed properly (http://www.floridatoday.com/content/blogs/space/).

This is my first post, so please advise me if anything is amiss ...

It is a recoverable first stage, that has to go through extensive refurbishment and rebuilding.

I haven't been following Ares I development that closely, but I seem to recall that first stage reusability was at risk of being dropped.  Also, is the Orion vehicle still expected to be reusable, or is that TBD at this point?

It seems that the success that ARES I-X had determined some people to start thinking of a modified version called ARCARES (http://forum.nasaspaceflight.com/index.php?topic=19261.0)
http://forum.nasaspaceflight.com/index.php?topic=19261.0

What about the ISP of that rocket? Is it greater than the ISP of a similar space vehicle which uses an ordinary solid fuel booster?

Are there any remotely likely scenarios where they would have to press 39-B back into service to finish the Shuttle Program?

Obviously, 39-A would have to be seriously unusable and yet at the same time the Shuttle it last launched would have to safely complete its mission.  I don't see Shuttle flights ever resuming in the aftermath of a third Shuttle disaster.

Perhaps in a case where serious foundation damage on the pad or significant RSS/FSS corrosion were discovered?  Structural collapse imminent.

To get 39B back in service, my understanding is that the 39B Payload Changeout Mechanism would have to be re certified.  (Or could the 39A PCM be relocated to 39B?) The LO2 vent hood and crew access arm would have to be re-installed.

Could all of this even be possible in time to support finishing out the STS manifest?


I would say it is pretty certain that 39B will never launch another shuttle. The amount and type of mods that were done for Ares I-X pretty much sealed the deal. Obviously the GOX vent hood and OAA would have to be replaced, however the OAA mounts have been removed, not to mention the large VSS platform in the way now. Not sure how much of the PCR has been cannabilized. pretty soon we are going to start safing and inerting the hyper system, then start pulling components off of the structure. Plus other issues that have been found that need to be addressed just from age and corrosion. 39B has seen it's last launch for quite some time.

A "normal" upper stage doesn't get to be on its own until it's well out of the atmosphere.  Because Ares-I's first stage is so weak, it's upper stage gets to fly while there still is significant q.  If there was no recontact, doesn't the performance of the upper stage simulator indicate that's it's pretty severely aerodynamically unstable? 

The Ares I-X staging altitude was about the same as a Proton's first stage jettison altitude (40 km versus 42.5 km).  The staging velocity is in the same ballpark (1,488 m/s versus 1,797 m/s).  Proton is considered "normal" enough.  It's flown 348 times, and more times this year than any other commercial comsat launcher.

Ares I will stage higher (nearly 60 km) and faster (~2,000 m/s) than either Ares I-X or Proton.  (Ares I staging will occur at roughly the same altitude as Saturn IB - a rocket that worked pretty well.)  The Ares I first stage will also produce 1.25 times more total impulse than a Proton first stage, and 1.6 times more than a Saturn IB booster stage.  Hardly "weak".

I didn't realize Proton was a 2-stage.   :D

Of course it isn't.  It uses lower energy propellants in its upper stages.  What is your point?

That was posted yesterday - keep an eye on the NASA.gov homepage for many more imagery.

I just saw a picture via e-mail of a lovely, large dent in the side of the motor. No missing paint or displaced metal, so it likely was due to simple water impact. Location is right about the aft center/aft segment field joint.

Has this kind of thing been seen before?

Stupid question: Is it even conceivable that this could have happened at ignition?


I was wondering if, with the mention of paint bubbling, the high heat of the casing caused it to buckle from the impact into the cold Atlantic (if it impacted straight down and the water couldn't fill up inside the case).

The paint bubbling is from entry and is standard

Most 2-stage rockets have a more even delta-V split than Ares-I.

Most 2-stage rockets have a more even delta-V split than Ares-I.

There aren't many purely two-stage rockets.  There have been 61 orbital launch attempts so far this year, for example.  Only 8 were two-stage rockets and only 6 of those were LEO-bound. 

At least half of those 6 flights were performed by rockets with a substantially less than even delta-v split.  The other half were relatively limited in payload capacity.

Examples of two stage rockets with less than even delta-v split for LEO include Atlas 5-401, Delta 4 Medium, Taurus 2, KSLV-1, etc.  Zenit 2, Saturn IB, and Ares I all have/had less than even delta-v splits as well.

Real rockets are constrained by available propulsion, etc.  Perfect delta-v splits only happen on spreadsheets.

As for Ares I, it is attempting to do with two stages (payload mass-wise) something that no other two-stage rocket can, or ever has, done.  One might argue that it should have been a three-stage rocket, though at greater operational cost.  That it isn't "perfect", given the limited choices in U.S. high-thrust propulsion, is not surprising.

So what does that say for Ares I first stage reusability... I remember reading on here considerable concern about the heating of the first stage as it reenters, since the "real" Ares I stages considerably higher and faster... which means a faster, hotter reentry...

At what point does the entry heating do bad things to the strength of the casing (like heat annealing)??  Thanks!  OL JR :)

Isn't Ares-1 essentially a three stage vehicle, with the second stage intentionally leaving Orion in an "orbit" that intersects the atmosphere?  Or is that delta-V split insignificant?  Where is the line usually drawn?

And why would a "three stage vehicle" have "greater operational cost" than a Ares-1 with its solid motor, and cryogenic and hypergolic engines?

Who says perfect delta-v splits are even desirable? Given that 1st stage engines have to work at sea level pressure, but the majority of flight is in near vacuum, and (especially LH2) upper stages have higher Isp, asymmetric delta-v split should be the norm, not the exception.

Umm, Saturn INT-21?  I think it orbited just a little more mass than Ares I could.  By about 50 tonnes! And that was still way less than it's maximum of 118 tonnes.
