Interestingly, TWINS-B has reappeared on the MSDB manifest, and is sitting right next to L-26. I thought we'd seen the back of it when L-28 launched, but obviously that was not the case. Seeing as they are sitting next to each other on the manifest, and we know that TWINS-B is part of an NRO satellite, L-26 is the obvious candidate. If this is the case, however, it begs the question of the nature of L-26's mission. TWINS-B is going to Molniya orbit, but I am not aware of any NRO satellite classes which use this orbit and require a D-IVH to get there. All recent NRO launches to Molniya have used Medium EELVs (Atlas 401 for SDS, 411/DIVM+(4,2) for Trumpet). What could be big enough to need a D-IVH, if it is going to Molniya, if that is, indeed, where this is heading.

Perhaps NRO-26 is a satellite similar to the old Trumpet's USA 103-112-136.
Those satellites were all launched by Titan4-Centaur into Molniya orbit.

It is possible, but most people think that the role of those satellites is now filled by NRO L-22 and L-28, which where launched by D-IVM+(4,2) and AV-411 respectively.

The Launch Schedule shows this one for July 28 -- does it really take 3-4 months after the booster rolls out to the pad to get it ready to launch, or is this a case where there wasn't any better use for the pad and USA wanted to free up space in the HIF?

I am among them.
Hovever may be that, this sat, is not a new generation one, but as happened for DSP-23, the last in line of an old generation.
Substantially, may be that, they ordered three Delta IV to start the program, one for test, and two for old sats, diverted from Titan's.
Don't forget that these launches were delayed for years.

Post by: William Graham on 04/16/2008 04:35 PM
Okay. I've had another look at the mission patch, and I have noticed a few interesting features.

Firstly, the Statue of Liberty's crown could represent some form of dish or antenna - possibly a communication or radar reconnaissance satellite. Secondly, the differences between the mission patch on ebay, and the one on the tower suggest that there has been a change of circumstances surrounding what that star represents. There are 13 stars on the patch, 6 on the US flag, and 7 in the sky. This suggests that it may be the 7th or 13th satellite of a particular series.

I then compared it to several other NRO patches, from this, I was able to identify several similarities with the NRO L-21 payload patch.
Firstly, the group of five stars on the L-26 patch which contain the shooting star, are in a very similar pattern to the five stars on the left hand side of the L-21 patch. There are also 12 stars on the L-21 patch - one less than the L-26 patch. Sometimes the number of stars corresponds to a satellite's position in a series, and the fact that there is one more on the L-26 patch suggests that it could be the next in that series. This would also explain the shooting star - L-21 is now out of orbit, so the tail on the star in the patch was added to represent this (Antares' joke may not have been far from the truth) - possibly this was changed after the patch was painted onto the tower at LC-37, explaining the difference in patches - it will be interesting to see which version is painted on the rocket. There is also a similarity between details on the handle of the torch of the Statue of Liberty in the L-26 patch, and the Eagle's tongue in the L-21 patch, but I'm not sure what this could represent. Obviously L-21 was a lot smaller than L-26, but it is possible that it may be a new-generation satellite, and L-26 may be the last of an old series. Lacrosse 2 has been in orbit since 1991. Lacrosse 1, which was launched a little over two years previously, is long out of service. It was replaced during the second group of Lacrosse launches, but Lacrosse 2 was not replaced. I suspect that L-26 is it's replacement, and the last Lacrosse satellite before they are replaced by something a lot smaller. A launch to a 68° orbit, somewhere between 450-700km in altitude will confirm this. I would also expect a large payload fairing to be used (if different lengths are available).

I am disregarding what I said earlier about TWINS-B, as I don't think NASA know what is going on with it. NASA's Science Directorate seem to think that it was launched on 26 February (there was no launch on that date, although L-28 was scheduled for it, for a while). GSFC seem to think that is scheduled for a Delta IV from Vandenberg, in early 2008 (no such launch, although L-28 was transferred from Delta IV to Atlas). I think that L-28 carried TWINS-B, and the MSDB entry was a mistake. Anyway, according to the reported masses of the old Trumpet satellites, D-IVH would still be overkill, an M+(5,4) should be able to handle it, or even an M+(4,2) at a push.

I think this is either a big LEO satellite, or it is going directly to GSO. If I was a betting man, I would have money on Lacrosse.

I disagree with you there (morituri te salutant). Lacrosse 5 was launched from Canaveral as well (on a Titan). SLC-6 is not currently able to take D-IVH, and is closed for refurbishment anyway. Presumably if L2 is ageing, there will be some urgency to get a replacement up, so they can't wait for Vandenberg.

How could SLC-6 be closed for refurbishment?  The place was just modified for Delta IV a few years ago.  There have only been two Delta IV launches from Six.  

Are they prepping it to support Heavy?

As I understand it. I believe the next launch will be in December 2010. Lacrosse 2 will be approaching 20 years on-orbit by then, assuming it is still going - Lacrosse 1 only lasted 8 years. That is why I suspect it will be replaced soon by an east-coast launched satellite. I could be wrong, but that is my belief.

I don't know why they couldn't have done this when they built it.

Post by: William Graham on 05/01/2008 07:53 PM
Apparently, ULA have announced that it is a GSO launch. Much to my surprise this eliminates Lacrosse. If, as Faustod stated earlier, this satellite was originally scheduled for Titan IV, it is almost certain to be Advanced Orion. Otherwise, it could be a successor. I'm not sure whether the codename Prowler has been used in conjunction with such a programme.

Makes you wonder, doesn't it, what the heck is going on with that payload?  For this long a delay, it must be nearly as complex as Shuttle.  It must be a massive program, employing tens of thousands at least. 

It must cost billions, each year.  There must be cavernous satellite factories hidden beneath mountains somewhere.  It must be the secret weapon that will find Bin Laden.  Maybe it will solve the credit crises and the energy crises and global warming all at once.

LOL. Keep in mind this mission has been planned for Titan IV, ca. 2003. It can't solve the energy crises and global warming because both were not recognized as problems by then. Oh wait, they are redesigning the super satellite because of these new enemies. Now I have hope again.

How do you guys define "left over"?  The TIV program wasn't cancelled abruptly.  So were these payloads just planned before the program ended and the assumption was that they would fly on a Titan, or were they actually manifested on a Titan IV?
Title: Re: Delta IV Heavy: NRO L-26
Post by: Analyst on 10/05/2008 02:47 PM
Well, this is iffy. Its a payload

- from a satellite program,
- which consists of several (almost) identical satellites,
- and many or all of these satellites were launched by Titan IV as long as it was available.

Examples: DSP, ELINT and SIGNIT payloads. There were 10 DSP second generation satellites, 9 of them used an IUS and 8 of these a Titan IV (one used a Shuttle) The tenth, the leftover, used the second Delta IV.

I wouldn't call them "leftover"   EELV's replaced Titans IV/II, Atlas II and Delta II.  Just as there was DSCS, GPS, DMSP, etc that flew on EELV's, there are "other" payloads that will or did.  The EELV spec enveloped the largest Titan payload.  So when the EELV 's were given a go ahead in 1997, spacecraft programs could continue to design/build to the same requirements as they did before.
The same thing occurred during the transition from shuttle to T-IV.  The DSP-23 spacecraft could have flown on the Shuttle, Titan-IV or EELV (I say EELV, since it was light enough for an Atlas V too).  DSP-23 (and a few of its sisters) were probably procured after the transition from Shuttle to Titan-IV but it just a continuation of a production line vs a new design.

Also just a note for those who didn't read between the lines, EELV specs were ultimately driven by the shuttle

Wasn't there a Titan IV left over at the end of the programme? IIRC, it was just a core vehicle (no upper stage), which seems to suggest a LEO payload. DSP would have needed an IUS, and a GSO ELINT (which is what L-26 is believed to be) would require a Centaur. That suggests that there could be a leftover LEO bird waiting around. L-15's out of sequence designation suggests it has been delayed somewhat.

Makes you wonder, doesn't it, what the heck is going on with that payload?  For this long a delay, it must be nearly as complex as Shuttle.  It must be a massive program, employing tens of thousands at least. 

The string of delays causes me to lean more towards this being the first new-generation GSO ELINT satellite (Intruder), as opposed to the last current-generation satellite (Advanced Orion).

This year's results are, unfortunately, par for the course for the past five years or so.  Since 2004, inclusive, the U.S. has averaged only 16 orbital launch attempts per year.  Each year was preceded by seriously flawed predictions of many more launches.  I find it interesting that this collapse from previous launch totals (in the 20-35 per year range) has coincided with the "EELV Era".  One wonders if this isn't turning out to be the "DELV Era".

There's a conveniently preserved 2004-era EELV manifest here (http://spaceflightnow.com/tracking/eelv.html), and a summary of EELV flights to date here (http://space.skyrocket.de/index_frame.htm?http://www.skyrocket.de/space/doc/eelv.htm).

As of 2004, there were 25 EELV launches scheduled through the end of FY 2008.  Of these 25 payloads, 16 of them are still not ready for launch.  1 is currently delayed a few months due to LV issues, but was 3 years late before those issues arose.

When the USAF created the EELV program, they hoped to save money for government payloads by sharing fixed costs with commercial launches.  In a further attempt to save money, they included a clause saying that the USAF couldn't pay more than any commercial customer.  The anticipated flood of commercial launches never materialized, and the lowest-price guarantee made EELVs commercially uncompetitive.  This has put EELV into the typical procurement death spiral.  There was a chance for NASA to help break out of this spiral by buying 4-ish EELV launches a year to service ISS, but they went off to do Ares I and COTS instead.

So here we are.  Individual launch vehicles have very little to do with the current state of affairs, the main issues are programmatic and payload-related.

Yes, now.  If you went to ULA and said "I really want to buy a Delta IV" they'd sell you one.  They just realize that no non US Government customer would ever want to buy one, and so aren't going to keep around the marketing and business folks needed to try to sell them.

2) Yes, milspace is a disaster these days.  Yes, it's hard to assign blame accurately between the DoD and the big contractors.  No, the EELV program has not turned out as hoped.  But the EELVs actually exist.  They cost more than desired, and they have launch vehicle delays here and there, but a government agency with a satellite that's ready to fly can generally get it to orbit at a cost that's not completely outrageous.   By the standards of milspace procurements over the last decade, this is a stunning success.

You can argue "EELV is a failure because it costs way more than the Atlas/Delta/Titan that it's replacing".  You can argue "EELV is a failure because it didn't get a big share of the commercial launch market".  You could argue "EELV is a failure because it's less reliable than Atlas/Delta/Titan".  But arguing "EELV is a failure because it only flies four times a year", when there haven't been a bunch of payloads sitting around waiting for rides doesn't make sense, and if you draw the conclusion "EELV only flies four times a year, so we need a new rocket that will fly 8 times a year", you'll have been lead astraay.

EELV is a failure because it costs too much.  Since it costs too much, it cannot compete for commercial launch business.  Since it can't garner commercial launches, it rarely flies.  Since it rarely flies, it costs too much. 

(I would be happy to see four launches in a year.  EELV has actually only averaged about 3.5 launches per year since inception.  It cost more than $1.2 billion to perform two EELV launches this year.)

It should be noted that much of the delay in the EELV flight rate is due to issues outside the control of the rocket programs.

Payload issues are playing a role here, but so are RD-180 issues, and pyroshock testing issues, etc., on the launch vehicles themselves.

As for the payloads, why did the U.S. seemingly decide to redevelop all of its defense satellites at the same time that it brought new launch vehicles on-line?  This does not appear to have been a good idea! 

Quote
The net result is that the flight rate slows down, but that goes hand-in-hand with a greater degree of confidence that the rocket will get the job done. I'd much rather wait out the delays and fly my comsat on an Atlas than put the bird on that crap-shoot of a booster, the Proton.

Proton only appears slightly more risky than an EELV, so far.  23 of the 26 Proton M/Briz M missions have succeeded to date, compared to 20 of 22 EELV missions.  A Briz M failed earlier this year, but Proton M/Briz M has already flown four consecutive successful missions since then - matching the current Atlas V success streak.

EELV is a failure because it costs too much.

That's not a metric.  Relative to what?  EELV is cheaper per kilo than any preceding American rocket.

What kind of car do you drive?  EELV's are expensive on the world market for the same reason the big three are: American labor rates.  Wanna trade your national security and standard of living for a cheaper rocket?  I don't.

What's more (!): unlike American cars, EELVs are much more reliable than foreign rockets.  I don't count Heavy Demo or AV-8 as material failures.  Heavy Demo failed, but no expensive payload was lost.  AV-8 came up short, but the satellite survived and didn't lose much of its life - unlike recent foreign failures which have lost more life or been completely catastrophic.

I shrug.  You continually impugn EELV without providing any alternative, which there isn't.  They're the best rockets in existence (Falcon 9 not yet existing).

Post by: Analyst on 12/13/2008 02:11 PM
I see and understand your points. And my "feeling" indicates Proton and Zenit are a little less reliable than EELVs.

But you have to admit the following: The timescale for testing / fixing problems with US rockets (EELVs and Delta II) is simply to long: Delta II Star 48 problem > no launch since March, similar for Atlas V. Or the famous Delta II RS batteries. And this for problems which did not lead to a launch failure. Then there is a failure "recovery" times will grow even more, two STS groundings being the extreme.

These extremes are not observed with Ariane (IV or V), which is the closest to US launchers not only because of similar labor costs in western Europe. So let us compare the market share of EELVs vs. Ariane V.

 A rocket that's flown as long as Proton has should not have such an abysmal flight record. But, oh yeah, it's cheap (relatively) and I can fly my sat real soon.


I shared your perception of Proton reliability until I sat down and tallied up the actual results.  http://www.geocities.com/launchreport/reliability2008.txt

It turns out that Proton is pretty reliable for a GTO launcher.  Proton K/DM-2M, for example, ended up with a better record than any other existing commercial counterpart.  The second most-reliable big GTO launcher was Proton K/DM-2.  Ariane 5 ECA ranks third behind these two, but is actually first among actives now that Proton K has been retired.  Then come the EELVs, Zenit 3SL, China's CZ-3 series, and Russia's current Proton M/Briz M which is in the process of recovering (statistically) from two failures in two consecutive years.

As for Russian launch vehicle reliability, note that six of the 10 most reliable on this list are Russian/Ukrainian.  Only two are from the United States.  Russia has more failures (and more successes) because it flies two to three times more often than the U.S.. 

Which begs the question - if all of the money being spent on EELVs is supposed to buy extra reliability, where are the results?

This tends to always happen (in any area, not just RS or reliability), when things have gone really bad in the past. But they haven't: Last big trouble has been 1998/99. Well, maybe they haven't happened because of this regulation? I doubt it.

Again, thanks for your time explaining. I don't want to imply US launchers are worse than others, I only observe flight rate and commercial success and wonder why other launch companies / rocket builders / payload providers etc. do - right now - much better.

Dubious!!  You stack your list against American rockets.  Of your 47 on the list:
former Soviet are 24 (51%)
American are 9 (19%)
Oh look.  20% of the top ten are American, the same fraction as the overall list.  Plus, you skew the share of Eastern bloc rockets by separately counting 6 different flavors of Proton and 7 different flavors of Soyuz.

Which begs the question - if all of the money being spent on EELVs is supposed to buy extra reliability, where are the results?

Ed does make a good point on this one.  The EELV prime(s) can be blamed for bad supplier management.  USAF and NASA should make this a point of emphasis in future management meetings.

Pippin, yes, I agree.  I was not implying that we should relax reliability targets for launches, at least in this media environment.  If the business trade were there (cheaper missions even if 10-20% go in the water) and if public perception could be altered to accept such failures, then decreased reliability would be a rational strategy.

And to the community, as padrat and Analyst allude to, it is often the government oversight that delays flight resumption after finding bad hardware on the ground.  Usually the primes find the fault fairly quickly, solve it, but then have to justify the cause and corrective action to the government (including investigating some possible causes a proper weighing of risk would deem so non-credible that they should not be worthy of pursuit).  These delays are from both the mission assurance function of the customers and the public safety function of the Range.  In fairness, though, there are the occasional problems whose cause or corrective action vex both contractor and government engineers.

Three of the top five families are Russo/Ukrainian.

Taking an aggregate from the top 15 in this list
gives the following by-nation result.

Russia/CIS   2654/2831 = 0.94
USA            724/787 = 0.92
China          108/119 = 0.91
Europe           37/41 = 0.90
Japan            18/21 = 0.86

However you slice it, the history shows that
the former USSR orbital launchers are just as
reliable as any other nation's rockets, and
probably more so.

I think the problem of EELV launchers is a result from monopoly of ULA in U.S. government´s "market".

The problem still existed before ULA was formed.

Has nothing to do with ULA.  And it is unrelated to the other programs

EELV reliability doesn't seem bad for the amount of flight experience they have had. If they continue to fly I expect their reliability will improve.

However you slice it, the history shows that
the former USSR orbital launchers are just as
reliable as any other nation's rockets, and
probably more so.

 - Ed Kyle

One difference is that Western rockets tend to get more reliable when they fly a lot, while the reliability of Russian rockets stays about the same, no matter how much they have flown. For example the Delta II and the Ariane 4 are/were very reliable.
My guess is that when the EELV's and the Ariane 5 fly enough (a 100 times or so) and aren't redesigned drastically every 10 or 15 flights they will have a success rate of 92-95%.

I disagree. To give one example, Proton has become much more reliable since the 1960s - It failed every few launches, and I believe it took 61 launches before the Proton-K was accepted into service. In the last 10 years, there have only been three core vehicle failures.

I should hope so! They've had 40 years and 340 launches to get it right! The fact that they still have had recent booster problems (remember JCSat and the bad 1-2 sep?) could indicate QC problems (which I understand they're working on).

Proton is a pretty good LV, sure, but they've had a long time to work on it. It should be.

Let's compare Proton with Ariane 4, two launchers of the same class (Proton about 6 tons to GTO and Ariane 4 about 4 tons).
At Gunter's space page, there is nice list with the launch history of both rockets:
http://space.skyrocket.de/doc_lau/ariane.htm
http://space.skyrocket.de/doc_lau_fam/proton.htm
If we look at the last 74 flights of the Ariane 4, we see there wasn't a single failure anymore, while Proton had 2 total and 3 partial failures in its last 74 flights.
Ariane 4 was a real mature vehicle, while Proton now and then still encounters a problem.

Ariane 4 posted an excellent record, but keep in mind that Space Shuttle recorded 88 consecutive success before Columbia, the Soviet Union's R-7 series once posted 133 consecutive success before failing again, and so on.  Although the Proton series has suffered four failures so far this decade, it had suffered five at this point during the 1990s, seven during the 1980s, and so on.  The trend is improving, though I'm sure that Krunichev would like to see even better results.

Titan offers one counter-example of the idea that Western reliability improves with time.  The Titan series (all types) recorded better reliability during the 1980s than it did during the 1990s.  STS is another example, having done better during the 1990s than during this decade.

I think that people are failing to understand the proper idea of rockets in the east!
For example in NASA, a launch vehicle family tends to be retired after about 20-25 years max! And by that time they will be performing to their capability!
In the east, people tend to upgrade the existing launchers and keep the family for what, 40 years or something and keep upgrading them and retesting them! So the chances of failure will be higher. Take Proton for that matter, it flew first in 1965, same as the Saturn age. But Saturn was retired with the arrival of Titan family! While Proton was being upgraded with new technologies and being retested!
So we tend to forget that the present Proton Breeze M is almost completely different expect or some things. So, launched in 2007 the new Proton Breeze M is just like something new and can't be compared to a Proton of 1960s!
So it's just the fact that Russian mindset to keep upgrading old rocket designs  and constant retesting somewhat fails it!

These are several misconceptions:
* There are not that many NASA rocket families besides Saturn and Shuttle
* Why are the chances of failure higher, when you use a launch vehicle ober a longer period?
* The retirement of Saturn had exactly nothing to do with Titan
* The Proton-M of today is not so much away from the original Proton (e.g. the evolution of Thor to the Delta II of today (or even Delta III), which are really different)
* The russian practice is to use a rocket design unmodifed as long as it is possible and then only minor modifications are made. US practice is to upgrade old rocket designs over a long period  with rather extencive modifications (e.g. Thor -> Delta II, Titan I -> Titan IV, Atlas ICBM -> Atlas III)

I couldn't disagree more.
1) The more a system is used, the more chances there are to iron out major design flaws - if it isn't broken, don't fix it. A lot of recent Russian failures have been down to QC issues.
2) Up until EELV, the USA followed the same approach - Delta II is based on a design which first flew in 1957. Atlas II, which was only retired in 2004, was based on an equally old design. You state that Saturn was retired when Titan arrived, but Titan actually flew before Saturn.
3) The Atlas V upper stage is based on a design first flown in 1962. The same engine type is used by the Delta IV upper stage.

But the Shuttle is a special case, because with the failure of Columbia, the "rocket part" of the space shuttle worked, but damaged the "re-entry" part.
R7 too, because it has flown more than 1200 times, if the Ariane 4 series had flown 1200 times, who knows how many successful consecutive launches it could have achieved.
Proton's amount of failures decreased in the last three decades because they flew less every decade too. +60 this decade, 90 last decade and 110 the decade before.

Post by: johnxx9 on 12/15/2008 03:43 PM
See, a particular launch vehicle needs sometime from when it flies first, to reach its max ability! It may be 4-5 years or anything! But if you tinker with the rocket before it has its max capability, you'll end up having required to test the vehicle again ! Again, the vehicle will not be at it's best and you tinker with the design!

That's what has happened to Proton! Before a particular version reached its max capability, they started experimenting with the avionics, core engine, upper stage! When you do all these things together it'll be better, but every now and then if you keep making changes that are not so minor, it will result in decrease in the success rate ! 

The Proton Breeze-M is almost completely different from early versions expect for the air frame and design ! Many things have changed like avionics, fuel (early versions used kerosene), and also the stages themselves have gone through many major changes!

Heres the problem, instead of bringing all these changes at once into a new vehicle, they kept adding them on one-by-one onto Proton ! And every time the vehicle had to be tested and retested !!!!!
Title: Re: Delta IV Heavy: NRO L-26
Post by: Skyrocket on 12/15/2008 03:59 PM
Excuse me, but you have probably no knowledge of the development history of the Proton, which has pretty few versions compared to many other vehicles. The one-by-one development practice as you've critisized above was done on vehicle like Atlas, Delta, Thor, Titan. Often not two consecutivly launched vehicles were identical. But in general russian (or soviet) launch vehicle were rarely changed, as they are really as close to  "mass production" as a launch vehicle can get.

"The combined cost of the NROL-26 spacecraft and booster is upwards of $2 billion."

Makes me wonder where this ranks on the "most expensive space mission" scale.  Apollo missions must have cost substantially more than this.  Cassini cost more.  Hubble too, and surely several ISS missions if the cost of the station hardware was included.

Spaceflight Now is reporting this mission uses a 3-burn upperstage profile as did the two flights before. This strongly indicates a GEO mission. The long launch window indicates GEO too. So most likely a big SIGNIT/ELINT, like the two different types launched by Titan 4. Probably a (improved?) "leftover", as discussed before.

I still maintain that the leftover is more likely to be a Lacrosse on L-15. I think this is the first "Intruder" (IOSA) integrated ELINT/COMINT. There have been some news articles listing this as the "most expensive" NRO satellite programme ever (I don't know how reliable that is - isn't the budget classified), which would suggest it is something new.

Quite a lot of recent NRO high-orbit ELINT satellites seem to operate in threes (three Mentors, three Mercurys (including the failed one), three Trumpets (assuming 184 and 200 are Prowler), three Magnums, etc.)

Of course, it could be a replacement for the failed Mercury, but I still think it is more likely to be a new programme.

We should drop the term "leftover", it generates confusion. And yes, I am guilty of using it.

I wouldn't be surprised if the GEO and Molniya orbit satellites are the same design and program, specifically the only ones which used the 86 Titan Centaur shroud (Trumpet and Mercury).

Good afternoon, here is the launch forecast for tomorrow along with the official launch delay release if you have not seen it. Thanks, Mike

 

Launch Day Forecast:

 

Probability of violating weather constraints: 10% --

 

Primary Concerns:  Ground level (54 ft) winds --

 

24-Hour Delay Forecast:

 

Probability of violating weather constraints: 30% --

 

Primary Concerns:  Ground level (54 ft) winds --

 

 

Synoptic Discussion:  The front that stalled to the south of Cape Canaveral yesterday returned back over the area as a warm front this

morning.  An upper level trough will enter the Southeast US this evening, pushing the surface front though Central Florida again as a

cold front.  The front will cause thick layered clouds, precipitation, and windy conditions early this evening.  This weather will clear

overnight, and high pressure will build in from the west, bringing favorable weather for launch Wednesday evening.   There is only a slight

concern for a violation of the ground wind (54 ft) Launch Commit Criteria.

FOR IMMEDIATE RELEASE
 
DELAY OF DELTA IV-HEAVY LAUNCH
 

CAPE CANAVERAL AIR FORCE STATION, Fla. – The launch of a National Reconnaissance Office payload aboard a United Launch Alliance Delta IV Heavy scheduled for 7:49 p.m. tonight from Space Launch Complex 37 has been delayed 24 hours.

During final walk down inspections, some minor damage to the spray-on foam insulation for the interstage doors was discovered.  This insulation will be repaired prior to flight, but the work will not be completed in time to support the roll of the mobile service tower as planned for today.

The new launch time is now set for Jan. 14, 7:45 p.m. EST.

Media representatives interested in covering the launch from the Kennedy Space Center News Center must report to the parking lot at the new KSC Badging Station next to the KSC Visitor’s Complex on State Road #405 on January 14, at 6:15 pm for badging and escort.  Media with a permanent KSC badge will not require an escort and should drive directly to the KSC News Center, which is the press site for this launch.

Prowler: USA-184/200/TBD

Your 'Mentor'  sats are the ones I still call 'Advanced ORION' because I haven't seen convincing sources tie the MENTOR name to them. They are a continuation of the MAGNUM program under another name:
   RHYOLITE = AQUACADE  = MAGNUM = ORION = (?MENTOR)
 
Your 'Prowler' sats, I strongly doubt PROWLER is the right name for USA-184/200, but maybe you have a source that knows b etter. In any case, these sats are in the same series as TRUMPET (although a new generation of that series)
  JUMPSEAT = TRUMPET = (?Advanced TRUMPET)

And of course MERCURY is the series of GEO sigints whose earlier names were
    CANYON = CHALET = VORTEX = MERCURY

There are generation/block changes within these programs, but they don't necessarily coincide with the changes in BYEMAN-style codename, which happen e.g. whenever we outsiders figure one out.

Launch of Delta IV Heavy NROL-26 Scrubbed

 

Cape Canaveral Air Force Station, FL, Jan. 14, 2009 - The scheduled launch of a United Launch Alliance Delta IV Heavy with a National Reconnaissance payload was scrubbed for tonight.  Technicians are working to resolve a gaseous nitrogen valve issue in the ground support equipment.  The very dry gaseous nitrogen is used to evacuate the air from various compartments in the launch vehicle whenever cryogenic propellants are loaded, because the extremely cold temperatures of the propellants would cause water in the air to condense.  Without this piece of equipment working properly fueling of the vehicle could not take place and the issue could not be resolved in time to make tonight’s launch window.  The launch is rescheduled for Thursday, Jan. 15, at 7:41 pm.

The fairing looks like the Titan-derived aluminium one, rather than the composite one. That could add some weight to the arguments that the payload was transferred from a Titan IV.

Launch of Delta IV Heavy Postponed, New Launch Date to be Determined

Cape Canaveral Air Force Station, FL, (Jan. 15, 2009) – Mission managers have decided to postpone today’s launch of a United Launch Alliance Delta IV Heavy with a National Reconnaissance Office payload for two reasons.  First, work continues to resolve a gaseous nitrogen valve issue within the launch pad ground support equipment.   The very dry gaseous nitrogen is used to evacuate the air from various compartments in the launch vehicle whenever cryogenic propellants are loaded, because the extremely cold temperatures of the propellants would cause water in the air to condense.   Second, there is a probability that increasing winds due to an approaching cold front would violate vehicle exposure criteria tonight.  The Mobile Service Tower is being rolled back into position around the Delta IV Heavy this afternoon. Mission managers will convene this evening to determine the date for the next launch attempt. More information on a launch date and time will be released when available.

This is nothing. I remember the first few launches where there would be hold after hold as things went wrong with the vehicles - battery voltages, pressures, temps, actuators. The later ones seem to be quite a bit cleaner in that regard - there was only one non-weather hold in the past 4 flights.

I make it three. GOES-N scrubbed twice due to technical issues, and there was a short hold in the DSP-23 countdown, but this was resolved within the window.

Of course, that's not counting delays before the start of the countdown. This launch is already over three years behind schedule, and there hasn't been a Delta IV flight since 2007. Only one Delta IV has launched within a year of its scheduled launch date.

Delta IV Heavy Launch Rescheduled for Jan. 17

Cape Canaveral Air Force Station, FL, (Jan. 15, 2009) – The launch of a United Launch Alliance Delta IV Heavy with a National Reconnaissance Office payload has been rescheduled for Jan. 17, 7:33 p.m. EST.  The primary reason for rescheduling the launch on Saturday is the current weather forecast. The forecast for Friday predicts a 70 percent chance of high winds exceeding both Mobile Service Tower roll and launch criteria.  The forecast Saturday significantly improves to only a 20 percent chance of weather violating launch criteria. Concerning the gaseous nitrogen valve issue associated with the launch pad ground support equipment, mission managers state the valve will be fully repaired and mission capable to support this launch attempt.

Since it has now been moved to saturday anyone willing to hazard a guess based upon prior GSO flights how long after launch the third and final circularization burn will be if this is a GSO mission and if the third burn will be visible for us in north america?

Pile on enough warm layers and it would be great to sit up early sunday morning and see if one can catch it.

Of course, that's not counting delays before the start of the countdown. This launch is already over three years behind schedule, and there hasn't been a Delta IV flight since 2007. Only one Delta IV has launched within a year of its scheduled launch date.

I'm pretty sure GOES-N launched without any unplanned holds in the 2006 attempt. I don't count the 2005 scrubs. The DSP was the hold I was talking about, and I'm not even sure it was a vehicle issue (they said it was "data monitoring for composite ramp temps" which has to do with the PAF)

As for your other point, I already made a big long post about how if one launch is delayed, they all will be even if the next vehicles in the pipeline are clean in the DSP thread. I count the "scheduled" launch date as that announced around or after the last flight went off. It is unreasonable to (for example) expect them to launch one scheduled for June 7 when the previous one hasn't even gotten off the pad yet as of June 9!

Look at the NROL-22 launch. It took them a long time to prep that one for flight and that delayed the next flight (DMSP) for a while even though that vehicle was relatively clean and was only delayed about a month from the date announced after the NRO flight. There was NO way they could make DMSP fly any earlier when NROL hadn't flown. The flight order can't change and if one launch is delayed it will affect the rest even if there are no problems with the rest of them.

Therefore I count the original launch date (and thus the lateness of this flight) as whatever date was announced near or after DSP-23.

Yes, you should definitely be able to see it real well from anywhere near Orlando (further east the better).  Even by Disney, you can still see a nice size light in the sky.  Though, it all depends on the cloud cover.

If you have a car, you can get a really good view of the Pad from the *second* SR-528 causeway just as you enter Port Canaveral (check Google maps) roughly an hour down the road from where you are.   There will be hundreds of other spectators so you won't miss the crowd :)

I've never seen a launch of any kind and I happen to be in Orlando.  Will I be able to see much of anything?  Thanks.

If you have a car, you can get a really good view of the Pad from the *second* SR-528 causeway just as you enter Port Canaveral (check Google maps) roughly an hour down the road from where you are.   There will be hundreds of other spectators so you won't miss the crowd :)

You could spend the day at the Space Center and see all the sites there.

And the beach area is a nice place to visit anyway -- at least on warmer days than today!!! :)

With shuttle launches one can see all up and down the east coast, would that be possible for Delta IV?  I am in Virginia Beach right now, so was wondering if I could briefly glance her going by if the weather is right....

I would say it's highly unlikely.  You can see the shuttle launches because their on a 51degree inclination which takes them up the east coast.  Delta IV is going to a geostationary orbit which means they'll be launch due east.

Edit: typo on the ISS inclination

The SSP hasn't flown a 57° inclination mission since STS-99 in Feb. 2000! ISS resides in a 51.6° inclination orbit.

I remember seeing a Delta launch while standing in the carport at the Orlando Airport La Quinta sometime around 1990.  I didn't know exactly what it was at the time (other than a launch), but got some details in news reports later that evening.  There wasn't much to see -- just a contrail against a clear blue sky, but I was impressed by fact that I could see it at all.

I was somewhere in L.A. late one afternoon when I saw the classic contrail of a launch from Vandenberg, probably an ICBM test flight.  That' a good distance away too.  The trail got wildly warped by winds and dissipated slowly, just like a Shuttle launch.

Back in the 60's I was living north of Atlanta and could see barium clouds from sounding rockets launched somewhere (Eglin?) on the Gulf Coast.

It gives you an impression of great height and speed, especially if you're close enough to see the exhaust flame even as a tiny bright dot.

This one should be pretty visible from Orlando since it rises vertically longer than other rockets before pitching over.  These Delta IV heavies are slow risers, max Q is under 400 psf IIRC.

When I lived in Orlando, I got to see a few STS launches from there during clear days. Pretty neat. You can follow it with your eyes until SRB separation, then it becomes a very tiny bright dot without any trail.

Unfortunately I never got to see one closer :( , since the Columbia accident occured, and I moved away before flights resumed.

I saw the last Delta IV nightlaunch from all the way up in Jacksonville. If it's clear between Orlando and the down range, you should be able to see it. I watched the updates here on NSF and once I saw it had launched, I just walked outside and looked toward the cape. You could see it very well. I estimated the heading toward the pad and used google earth to figure the direction and then set that against local landmarks. When my Father in law came out and asked where it would be I pointed in that direction and the darned thing appeared right at the end of my finger!

I'm glued to NSF this evening.

---  CHAS

No.  On Delta IV Heavy flights, all three CBCs ignite on the pad. The core CBC engine throttles down to 60% about one minute after liftoff. The twin strap-on booster CBC units burn at full thrust until the 3.85 minute mark. At that point, the strap-on units throttle down to 60% and the core throttles up to 100%. The strap-on units burn out and separate after 4.3 minutes. The core CBC shuts down about one minute later.

No. The two side CBCs will be jettisoned first after which the center CBC burns for a while longer after which it too is shut down and jettisoned after which the upperstage ignites.

---  CHAS

No. The outer two are run at full power for their entire burn duration and so run out of fuel earlier. The center one throttles back to 58% a few seconds after liftoff. When the outer two run out, the center CBC (which still has fuel left) goes to full power and the outer two separate. The center CBC runs for a little bit longer until 1-2 sep.

If you go back and watch the video of the last D-IVH launch, you can actually see the center engine throttle down if you look closely. The flame gets a little smaller compared to the outers.

They (the strap-ons) are jettisoned earlier. The core CBC runs on lower throttle for much of the flight so saves more propellant for a longer burntime instead of expending part of its kick on boosting the other two boosters along.

Always looks rediculously danagerous with the flame riding up the stack at launch. Would that even be safe for a manned launch?

It's safe for a billion dollar (or whatever it cost) military satellite, one would assume it would be safe for Orion.

In the animation, the fairing seemed to have three pieces... I seem to recall Titans had these types of fairings, and since this launch is using one it may make sense. Is that so?

Great news, thanks Ford :)

Impressive beast, indeed. Too bad this is a night launch again. The maiden flight was spectacular daylight footage.

Good, I'm not the only one that prefers day launches then! :)

Well, of course daylight's better. You can't see where the rocket's going otherwise ;)

Is it just me or does anyone else get suspicious with 'delays' on classified payloads.  My inner conspiracy theorist thinks they are masking the true liftoff window.  I know it doesn't matter as liftoff time lets people track it.  But I figure those NRO spooks like to mess with people.

They wouldn't have announced the launch window if they wanted to keep it a secret.

I think the first problem they had was the Met (weather) console couldn't communicate and upload the wind ascent data to the Heavy, after reconfiguring and using a backup console, they are ready to support, however the newest problem is that the winds ascent data from the latest weather balloon, number 7 is missing some information from 25000 feet or so. They are relaunching another balloon, number 8 to get the required data, send that data to the Delta office in Denver where they will code this information into a computer file, send that file to the Cape to be uploaded by the Met console to the Heavy. If I am wrong, someone correct me.

Well, close...

The L7 balloon data was recovered.  Also, there will be no more uplinks unless required (i.e., balloon data shows the winds changed too much).

I think they said the centre CBC "stayed safe", but I'm not sure.

Presumably that means it failed to arm, resulting in the hold.

Neither, it was from shutting down LH2 replenishment.  The LH2 in the umbilicals and cross country lines has to go somewhere

That happens when they reopen the boiloff/relief valves (which are secured for launch).  You get a burst of GH2.

There used to be a video on the Boeing site, can't find it now though. :( Maybe you can go through web.archive.org and find it?

A lot of the charring on that first flight was because of the FRF. At shutdown the flame clung to the vehicle.

Not sure about 24 hours. I found a 15 hour one. Two others lasted 14 hours, one of which failed at T+26s, and the other exploded on the pad.

"The launch team appear to have a good understanding of the issue... again"

I'm not entirely sure about that.

The question -- and I think they are being unusually cagy about details on this launch -- is do they have a better understanding of the first issue or a good understanding of a second one?

I can see something like this "script abort" resulting from several different underlying problems.

Are all these small issues coming up due to the infrequency of Delta IV launches? They have only launched ~1 per year since the Delta IV became available. Not a very impressive flight rate.

Not enough attempts to work out all the bugs?

Next Delta IV will be GOES-O from CCAFS on April 28 (hopefully) on a M+(4,2). Since it's a Medium hopefully the launch won't be delayed as much and have so many cliffhanger holds. (fingers crossed, knock on every single piece of wood within arm's reach...)

Kepler is in March, not Feb. NOAA-N' is in early Feb.

Oh, man! Looking at this image I just remembered words of Soviet rocket engines designer Glushko: “ With a good engine even a fence will fly”. This Delta 4H sure looked liked a fence – three connected sticks - when it was rising in the beginning in the bright flame. :)
It looks great though.

This one lifted off only two hours 14 minutes late.  That's better than a lot of my airline passenger flights! 

I remember trying to watch Atlas Centaur launches during the 1980s.  Hold - recycle - hold - recycle.  Over and over again until the window closed, then back at it the next day.  They always flew finally.  Somehow, Atlas eventually turned into an on-time launcher.

As for this Delta IV launch that seems to have frustrated several on-line observers here tonight, this really wasn't too bad for a big hissing bottle of liquid hydrogen!

And thanks Chris for the coverage.  I noticed that some of the "other sites" couldn't keep with the visitor traffic load, but this one did.

Atlas V-H has my vote (because then we could add back in all of the Orion systems left in the parking lot, not to mention all but one box is redundant and a Cosmonaut-rated booster engine), as long as the culture doesn't become Titan-ic between now and then.

Again, it's not reasonable to expect your flight to take off when the other airplanes on the taxiway in front of you haven't taken off either...

I know the "three year delay" thing is a nice convenient way of bashing D-IV but it's really not accurate. I won't dispute they have a few kinks to work out though, as illustrated by tonight's launch...

Darn it... I live in NC and I checked a few minutes before the launch was supposed to happen (the first time tonight) and everything seemed to be a go. I went out to the beach to see if I could see it from here as I can with many shuttle launches, but didn't see anything. I didn't know that it was because of a delay. I've never looked for spy satellite launches from here, so I was going to use this as a sort of test to see if they were visible from the beach here. I guess next time I'm going to have to have a little crew for me... someone on the computer calling me on my cell phone and updating me  :D Really wish I had known. It was still a nice night, though.

ULA Presser (they are going to send a hi res launch photo shortly):

 First ULA Delta IV Heavy NRO Mission Successfully Lifts Off From Cape Canaveral

Cape Canaveral AFS, Fla., (Jan. 17, 2009) – United Launch Alliance’s Delta IV Heavy rocket  carrying a payload for the National Reconnaissance Office successfully lifted off from Space Launch Complex 37 at CCAFS at 9:47 p.m. EST today.  This was the first Delta IV Heavy mission for the NRO. Designated NROL-26, the mission is in support of national defense. This was the third Delta IV Heavy launch in Delta program history.  A Delta IV Heavy demonstration flight occurred in December 2004, and the first Air Force operational mission was launched in November 2007.

“This first Delta IV Heavy launch for the NRO is the culmination of years of hard work and dedication by the combined NRO, Air Force, supplier and ULA team,” said Jim Sponnick, ULA Vice President, Delta Product Line. “We appreciate the support from our mission partners in achieving this milestone.  ULA is pleased to contribute to our nation’s security, and to continue our strong partnership with the NRO.  We look forward to launching many more NRO missions on ULA’s Delta IV Medium, Delta IV Heavy and Atlas V vehicles.”

The ULA Delta IV Heavy vehicle featured a center common booster core with two strap-on common booster cores. Each common booster core was powered by the RS-68 cryogenic engine. An RL10B-2 cryogenic engine powered the second stage.  Both engines are built by Pratt & Whitney Rocketdyne.  The payload was encased by a 5-meter diameter (16.7-foot diameter) aluminum, tri-sector payload fairing. ULA constructed the Delta IV Heavy launch vehicle in Decatur, Ala.

This was the first launch for ULA in 2009.  ULA's next launch is NASA’s NOAA-N Prime mission currently scheduled for Feb. 4, aboard a Delta II from Space Launch Complex-2 at Vandenberg Air Force Base, Calif.

ULA program management, engineering, test and mission support functions are headquartered in Denver, Colo.  Manufacturing, assembly and integration operations are located at Decatur, Ala., Harlingen, Tex. and San Diego, Calif.  Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg AFB, Calif.

For more information on the ULA joint venture, visit the ULA Web site at www.ulalaunch.com, or call the ULA Launch Hotline at 1-877-ULA-4321 (852-4321).

I'm not anti-Delta IV, I just think they should have ironed out the bugs before they became dependent on the system (ie. by retiring Titan).

Don't believe you would have seen tonights launch of Delta 4 since it was being launched due east from Pad 37.
Shuttle is visible to you in N.C. and most east coast states because the shuttle flies in a north east trajectory.

Yeah, Delta IV Medium (no solids), that's even slower. Atlas V 401 (also no solids) is not exactly a hot rod either. The Ariane 4s without solid motors were pretty slow too. Some people call it "slow", I call it majestic. :)

Wow that looked like one great launch! Congrats to ULA and everyone that made this launch (finally) possible!

Great picture.  I noticed the charring from the fireball is not nearly so bad as on other flights.  Maybe that is just a function of the breeze direction at launch time?

It sure was cold waiting out there at the cruise terminals waiting for them to light the fuze.  Beautiful launch, though.
It was OK for the first cutoff, but the wind picked up a little after that where I was.  Regardless, the launch was definitely worth the wait.

THANK YOU PAT CORKERY!

Wow. Love those mach diamonds.
Question: Would that be an injector issue with the right engine? Running a little lean or rich perhaps? Just slightly brighter in the exhaust plume than the other two engines.

It seemed to take forever for the D IV-heavy to clear the tower this time... Are there any examples of rockets which clear the tower any slower? The Shuttle seems to jump off the pad in comparison...

Saturn V

Absolutely, Jim...the one Saturn 5 launch I was lucky enough to witness (Apollo 15) was from south of the complex by CCAFS Gate 1.
I remember very clearly how long it took to actually clear the exhaust plume that obstructed the vehicle upon ignition.

No, my little point-and-shoot wouldn't focus on the rocket.  next time, I hope to get some good pics with my new camera, especially if I can figure out how to connect it to my 100mm, 60x, spotting scope.  I'm going to work on that at this week's birding festival at Titusville BCC campus (when I'm not working with the panthers, alligators, snakes, etc.).

Saw this launch with psloss and SEDS-UCF and a whole bunch of other people from Kars Park about 7-miles from the pad. It was every bit worth the three delays and cold temperatures. The sound was INCREDIBLE. Almost indescribable. I'm working on getting some pics available from the video I took, which ended up being a little better that I thought it would be given the auto-focus of my camera.

I remember when I first saw that timelapse (dunno if that's the correct term, or is it over exposure? - anyway) type of photo with a shuttle launch in the 80s and it was the first time I realized (as a kid) that they didn't "go straight up" ;D

long exposure or time lapse; definitely not overexposure.

It's a beauty of a shot. :) Nice arc.

Any news on whether spacecraft separation has occurred?

None, and I'm wondering if there will be any official statements to that effect. 

There is this today - a press release from PWR. 

http://sev.prnewswire.com/aerospace-defense/20090118/NESU00218012009-1.html

It says that "The upper-stage RL10B-2 helped place the satellite into orbit."  I suspect that PWR wouldn't have issued this if something had gone wrong with the RS-68 or RL10B-2 engines on this flight.

The release also states that "This was the 716th launch of a Delta vehicle under Pratt & Whitney Rocketdyne's power."  Not strictly correct, of course, (there have only been 328 Thor-based Delta and 9 Delta IV launches) but it was the 716th flight of a Thor IRBM, Thor SLV, Thor-derived Delta, Thor-derived NASDA "N" or "H-1", or Delta IV. 

ULA is saying that it will not provide any further updates beyond the "successful liftoff" notice.

Is the jiggle (about even with that blue star trail) wind shear, strap-on jettison or ground jiggle?

I'm guessing tripod vibrating due to wind or rocket rumble.

Would they release information if there had been a problem? The lack of any negative updates would suggest all went to plan. Understand why the Americans don't release details, glad we got the coverage we were allowed.

They'll release what their customer allows. Got to respect that, and I know you do.

Amazing panoramas, very high-res! I particularly enjoyed the LRO composite, I'd never seen a fairing so close to "real life", with perspective and people around to give idea of its size. It almost appears as if you were in the clean room!

Thanks for the links. Is that NASATech site a new outreach official site, or just amateur?
