A rather relaxed presser. Teams will be sporting mutton chops, mohawk hair styles and holding trinkets.

Currently 100,000 miles from Mars, closing in at 8,000 miles per hour.

No need to take the final course correction (contingency) opportunity.

One more op to update parameters to the onboard knowledge, if required. Don't expect it to be required.

Over the course of today we'll see if there is motion in the navigation. EDL update parameter 4 will come six hours out, where we might update MSL.

Midnight Eastern for live commentary.

I still don't feel well-enough prepared to interpret telemetry clues to potential PARTIAL landing failure -- too hard, bad attitude, whatever. I remember Viking-2's landing -- comm problems kept us in suspense. I give the mission 90% chance of safe landing but I think it's a lot more likely, too, that initial telemetry will be surprising and baffling, or even entirely absent - NOT a total indicator of failure, but worrisome. So I'll be on line here, watching and wondering -- and wowing.

An attempt @ illustrating the landing site as viewed from over 34k miles out. The landing site itself is still hidden behind the horizon but will come into view as MSL gets closer to EI.

 In exactly four hours from now, MSL will rest on the Martian surface - but for now, we're still 33400 miles out going 8432 mph. Puts things in perspective for sure.

Not sure if this already came up, but I'll post because it is awesome.

If anyone wants to see those neat computer animation shots in real time, it is the NASA JPL "Eyes on the Solar System" tool.  Open access to all.

http://eyes.nasa.gov (http://eyes.nasa.gov)
I've just run this tool in fullscreen with my nVidia Vision 3D glasses on - that's amazing!!!

I hate to be a spoil-sport but we shouldn't be cheering just yet IMO. Wait until Curiosity has confirmed its functuality. Would really suck to have gone through such a complicated landing sequence sucessfully only to have the mission fail on some technical glitch in the MSL. After the Hubble debacle i'm always a bit on edge about these things...

Gotta admit that that EDL system scared the hell out of me, despite all the really smart people behind it who know what they're doing. But it went like clockwork! I haven't felt this excited about a mission in a while...

(And I'm happy that Opportunity is still around to welcome Curiosity to Mars. I can't believe it's still going after all these years...)

I still am stunned that it actually worked, and that it worked with basically NO ERRORS!

I love when they called out a trajectory error of only 5.9 meters (out of 1.5 AU)!

Also, John Holdren has apparently never heard of Venera and Lunakhod.  ::)

Never pass up an opportunity to insult the Russians when they are flying our astronauts to the ISS.

Rep. Schiff Cheers Curiosity Landing at JPL Tonight, Renews Call to Fully Fund Mars Program


Pasadena, CA – Tonight, Rep. Adam Schiff (D-CA) released the following statement after the Mars Science Laboratory (MSL), known as Curiosity, successfully touched down on Mars and began its extraordinary mission:

"The landing of Curiosity is a remarkable engineering achievement and the culmination of nearly a decade of work by thousands of people here and around the world. In the coming weeks and months, Curiosity will answer many of the vital questions about Mars’ past and whether it ever had conditions suitable for life. But tonight we celebrate the genius of humankind.

“This success must reinvigorate our efforts to restore funding for planetary science and future Mars missions. While we have restored some of the funding –- almost $100 million so far –- much work remains to return the Mars Program to health. Without the certainty of future missions and support, we will find it impossible to maintain the most specialized workforce on earth –- the brilliant engineers and scientists who made this mission possible.”

Roughly 2 km. And the ellipse was almost due east-west, so they are either 2 km west or east of the target point. Either way, MSL is right in between the walls and central peak of Gale Crater.

No word on that yet, and I might have heard it wrong, but I think there was a call out shortly before backshell separation estimating the cruise balance weights would hit 1.5 km or so downrange from the rover. I think that means about 90 degrees off from the planned direction of travel, but I'm half guessing there.

It's been reported previously that they will not examine the descent stage up close due to risk of contaminating SAM with hydrazine vapors.

Roughly 2 km. And the ellipse was almost due east-west, so they are either 2 km west or east of the target point. Either way, MSL is right in between the walls and central peak of Gale Crater.

That's in the neighborhood of the accuracy you need for a human mission to Mars.

1.4 kg of fuel left onboard


I heard it as 140.6 kg

It was 1.4Kg, can't be 140Kg- too much.

Jim

Yeah, I figured that number was too high. They must have mis-reported it.



I'm sure I heard 140.6kg. Remember the descent stage started out with 390kg propellant aboard so seems a good number to me, given a smooth descent without complications.

You did hear 140.6, as I did. That's right. Going from memory, 4 thrusters at 800 lbs each (3200 lbs) and hydrazine Isp at 230 gives about 14 lbs/sec (6.4 Kg/sec). So, they had about ten seconds of propellant left. Seems about right. Certainly NOT 1.4 kg.

There is a margin, but I didn't think it was that big.

There's an update to this paper (this one is 2006), but I can't find it at the moment:

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090007730_2009006430.pdf

Page 13 says the +/- 3 sigma fuel consumption should be between 284.2 kg and 312.8 kg. That should have left 77.2 kg to 105.8 kg to spare.

Yes, I know but... (shrugs). I was shooting for humor - Opportunity has run the greatest planetary marathon ever. I know the prospects for MSL lasting as long as Spirit & Oppy is very poor. Perhaps as a cost cutting measure in future, NASA could send more small-ish solar powered Rovers with large, tilting and wiper-blade equipped arrays? ;)

It will be throttled down, not max rated thrust. The touchdown descent rate is constant velocity, so thrust should be right around m*g (750 lbs rover + weight of descent stage that I don't know).

If JPL expected no more than 105 kg back in 2006, and mass went up a bit since (I think), I really can't imagine they'd have ended up with more than that.

I agree though. 1.4 kg seems implausibly low. Maybe that was relative to a nominal remaining?

Good point - they were probably throttled back somewhere around 50%, plus or minus. And, yeah IF they said 1.4 (which I don't think they did) maybe it was a delta off what was expected to be remaining. For all that it matters. :-)

Will be very interesting if they can image the descent stage and see how far away it landed. What a great engineering accomplishment.

Looking forward to possible snapshots of MSL during descent from HiRISE, and to the HD descent images.

Craig (American Space): tell us about the landing

-Looked extremely clean
-Touchdown in the more benign side of our nominal expectation
-Very nominal
-Remarkably good navigation error (low side)
-Powered flight appears to be good
-(confirmation) landed with 140 kg fuel reserves (of 400 kg)

Notice the nationalistic hype at the conference... Bolden referencing the "four nations" that have been to Mars, but it was the US that made those nation's missions possible.... Later the reference that only the US has successfully landed on Mars... Not that I have a problem with it... Just found it a little odd... Could be because of the Olympics....

I counted... Not only are we the only nation to successfully land... But we did it SEVEN times! Is that count correct? Viking 1, Viking 2, Pathfinder, MER-1, MER-2, Polar Lander, Curiosity

The nasatv coverage showed a projected video with "MSL EDL LIVE telemetry visualization", that at first said "waiting for odyssey" and then showed computer graphics of the landing, with 38 stages listed on the left of the screen. On the bottom of the screen, it has drawn analog gauges of fuel, velocity, mach, acceleration and altitude. The nasatv cameras showed it intermittently.

Does anyone know if a video recording of that screen from start to finish exists? I would like to see the whole thing, instead of cutting from that to views of the people and back. Maybe do a split screen view or something.

During the webcast you could clearly hear a flight controller reading off the landing coordinates to 5 decimal places, so that is likely the source of the UMSF report.

Odyssey is the main relay? Aren't the other orbiters relaying data? Odyssey is 11 years old now... I would expect the newer orbiters to have better relay abilities....

Odyssey is the main relay for EDL, which I think from reading between the lines is due to its antenna configuration:
http://mars.jpl.nasa.gov/odyssey/news/whatsnew/index.cfm?FuseAction=ShowNews&NewsID=1265

Relay during the science mission will depend largely on which spacecraft is best positioned and not otherwise occupied. MRO is capable of the highest data rates.

MRO passed Gale Crater nearly overhead during Curiosity EDL, so distance to Curiosity is less (not looking to the side), more of a overhead shot, I'd expect.  Minimum range to target is about 275km.

With the fuel remaining and the 45 degree pitch, am I right in assuming the descent stage, relieved of Curiosity's weight, could have crash landed a long way off?  Potentially Kilometers away?  That will be interesting to find out.

If they get MRO images of the landing site, I would expect it will be in one of the images.  An MRO image of the MSL descent is supposed to be released today, so I am confident there will be others later.

I haven't heard any statements from the Prez. I wonder if he's awake and watching it or if he's sleeping...

They would have woken him up if they had found martians. But otherwise, he was sleeping.

Thanks to all for keeping the thread ticking over. Really top work from our community for this event.

El Presidente is awake:

For Immediate Release August 06, 2012
Statement by the President on Curiosity Landing on Mars

Tonight, on the planet Mars, the United States of America made history.

The successful landing of Curiosity – the most sophisticated roving laboratory ever to land on another planet – marks an unprecedented feat of technology that will stand as a point of national pride far into the future.  It proves that even the longest of odds are no match for our unique blend of ingenuity and determination.

Tonight’s success, delivered by NASA, parallels our major steps forward towards a vision for a new partnership with American companies to send American astronauts into space on American spacecraft. That partnership will save taxpayer dollars while allowing NASA to do what it has always done best – push the very boundaries of human knowledge. And tonight’s success reminds us that our preeminence – not just in space, but here on Earth – depends on continuing to invest wisely in the innovation, technology, and basic research that has always made our economy the envy of the world.

I congratulate and thank all the men and women of NASA who made this remarkable accomplishment a reality – and I eagerly await what Curiosity has yet to discover.

I was thinking the same thing. Bill Harwood reports that there were 140 kg. of fuel reserves after landing which would probably have translated to about 15-20 seconds of flight after disconnection. I would think that would power the crane quite a fair distance.

Rear hazcam: some dust on lens but otherwise alright and survived pyro event. A ridge on the horizon (crater rim?), looking into sun causing some saturation on the image.
Would that lens dust be from blowing the cover too early, or just the blowing itself?

  It proves that even the longest of odds are no match for our unique blend of ingenuity and determination. 

I heard Holdren say much the same thing last night, 'gutsy determination' overcoming 'long odds', with skill.

I'm not sure they understand what 'long odds' means.

In the 1990s, NASA was directed to use determination and sincerity to make difficult missions easier. It was one disaster after another.

You use insight and intelligence to REDUCE the long odds to much BETTER odds, and then when you launch, the odds are on your side, not AGAINST you.

You 'stack the deck' and 'load the dice'. You do NOT wish hard, cross your fingers, squeeze your eyes shut, and jump. Or if you do, you will fail, and you will deserve it.

I'm probably over sensitive to this loose wording, since I've been up close and very, VERY personal to the hideous costs of relying on enthusiasm and self esteem to overcome Mother Nature.

So I'll just shrug it off as meaningless political phrase-making, which is not inappropriate at this joyous time. And I'll jump up and down and wear a silly hat, for a proper celebratory interval, as the success warrents.

United Launch Alliance Congratulates NASA on Flawless Mars Landing

 

ULA’s Atlas V Successfully Launched Mars Science Lab November 2011

 

Centennial, Colo., (Aug. 6, 2012) – United Launch Alliance (ULA) congratulates NASA on the flawless landing of the Mars Science Lab (MSL) on the surface of Mars after a nearly nine-month journey to the red planet.

"ULA applauds NASA’s MSL team on the remarkable technical achievements witnessed today as MSL touched down to begin its science mission on the Martian surface,” said Jim Sponnick, ULA vice president, Mission Operations. “We could not be more proud of our role in safely and accurately delivering MSL and the Curiosity rover to orbit and look forward to the tremendous science that Curiosity will collect along with the yet unknown discoveries it will make.”

            Officials at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif., had prepared for a possible course-correction maneuver 15 days after launch, but navigators determined the trajectory was spot-on and did not need the maneuver.

            "This was among the most accurate interplanetary injections ever," said Louis D'Amario, mission design and navigation manager for Mars Science Lab during an interview in December 2011.

In celebration of MSL’s landing, ULA hosted an event for 300 school-age children where future rocket scientists conducted simulated launch countdowns and MSL mission landings to learn about the importance of this science mission, as well as to generate excitement about pursuing science, technology and engineering careers.

The MSL mission was launched from Cape Canaveral Air Force Station in Florida Nov. 26, 2011 aboard an Evolved Expendable Launch Vehicle (EELV) Atlas V 541 configuration vehicle, which includes a 5-meter diameter RUAG Space payload fairing along with four Aerojet solid rocket motors attached to the Atlas booster. The Atlas booster was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by a single Pratt & Whitney Rocketdyne RL10A engine.

“This was an impressive launch on the Atlas V,” said Amanda Mitskevich, program manager of NASA’s Launch Services Program. “The teamwork between NASA’s Launch Services Program, ULA and JPL made for an almost seamless integration and perfect launch of this historic mission."

Developed by the United States Air Force to provide assured access to space for Department of Defense and other government payloads, the commercially developed EELV Program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems. 

ULA's next launch from Cape Canaveral Air Force Station in Florida is the Atlas V Radiation Belt Storm Probes (RBSP) mission for NASA scheduled August 23 from Space Launch Complex-41.

Commercial Spaceflight Federation Congratulates the Mars Science Laboratory Team


Washington D.C. - The Commercial Spaceflight Federation applauds the team of explorers from the Jet Propulsion Laboratory, industry, and throughout NASA, that has successfully delivered the Curiosity rover to the surface of Mars. The Mars Science Laboratory (MSL) landed on the Martian surface at 1:31AM ET today after launching from Cape Canaveral in November.

“Curiosity is NASA’s next great explorer, a technological wonder that will bring Mars into laboratories and living rooms across the country,” said Michael Lopez-Alegria, President of the Commercial Spaceflight Federation. “Thousands of people designed, developed, built and delivered Curiosity, and they all deserve our acclaim. Congratulations, in particular, to the scientists and engineers of the Jet Propulsion Laboratory, who have led their team to such an inspiring achievement.”

Many CSF companies were involved in the successful delivery of MSL to Mars. Back in November, MSL began its journey atop a United Launch Alliance Atlas V rocket. Sierra Nevada Corporation and Aerojet worked on key components of the rover such as the descent brake and descent engines, respectively, among others. And Planetary Resources was a JPL contractor that assisted with various aspects of the MSL program.

Doesn't look like pyros to me.

If pyros look like pyros, they're probably oversized. The animation clearly shows a spring on the cover, but it was likely restrained by some sort of catch severed by a pyro. It could alternatively have been solenoid released like a pop-up flash on a camera, but usually a pyro is the lightest, simplest, and most reliable way. It could be as simple as thin wire coated in a little bit of powder that creates enough gas pressure to push a pin out of a slot or burns through a severable link.

Sorry for being late, but could anybody link me to info about the rover I'm particularly interested about how it is being powered.

There's a really good 2 page (PDF) description of the RTG here:
http://www.ne.doe.gov/pdfFiles/MMRTG_Jan2008.pdf

The RTG charges a small set of batteries that give engineers more flexibility in using the energy generated, similar to a hybrid car.

Lander module was told to go to the north, no idea where it landed though. If HiRISE takes an image that would be the only way they can find it.

They will be taking images of landing site (maybe in the next day but that would be a little hazy.) Best images 6- and 12-days from now, and in those images they can probably find where other components landing.

If they do find impact craters, they will try to avoid due to hydrazine. If they come across they will take a look, but will not go there intentionally. That's why they flew it north because they didn't plan on exploring north.

If they can find ballast that might be another story, but those are pretty far down the track.

From the presser (late getting to it):

Science instruments are still being tested.

MRO to be used to image rover, to provide updated traverse paths (in case of new dust hazards, ect).

The relay satellites can easily handle the data handling of both rovers since they are in two completely different sites

Q: What will be in the first color image? A: I don't know, but we can find out. Hopefully Mount Sharp & Crater Rim

Q: The team is working on the Mars 90 Sols & why?
A: For the team to be efficient to work on a real Mars day. 400 scientists on the mission & 300 engineers. We need to get to know each other really well and know the systems. Essentially immersion training (like a foreign language).

This is an amazing image!  I've always wished for external images of missions; they're rare.  I think video of the entire landing sequence could have been possible too: just before landing (a min. or so?) shoot out a small camera that embeds or otherwise lands into the soil.  Then it tracks and records video--imagine seeing the whole thing in HD.  Would have been incredible, not to mention extremely useful for capturing general public interest...

Not sure the camera would make it down before the lander, nor would it have a good focused shot, plus it'd be tough to find it afterwards and retrieve and then download the data.

RTG operates as a 'trickle charger'. We run off the bateries during the day but recharge the batteries at night. The heat from the RTG gets pumped around the rover to keep everything warm.

If the hydrazine was going to be a possible issue why didn't they just pre-command the descent stage to expend all prop and crash ballistically?

My guess is there is always residual... Plus as mentioned afterwards - they have no intention of sending the rover north, so that's where they sent the stage.

That appears to be essentially what they did, and there would still be residual hydrazine in the wreckage.

Rear hazcam: some dust on lens but otherwise alright and survived pyro event. A ridge on the horizon (crater rim?), looking into sun causing some saturation on the image.
Would that lens dust be from blowing the cover too early, or just the blowing itself?

Quote
If pyros look like pyros, they're probably oversized. The animation clearly shows a spring on the cover, but it was likely restrained by some sort of catch severed by a pyro. It could alternatively have been solenoid released like a pop-up flash on a camera, but usually a pyro is the lightest, simplest, and most reliable way. It could be as simple as thin wire coated in a little bit of powder that creates enough gas pressure to push a pin out of a slot or burns through a severable link.

Well, since I was the cognizant engineer on these now-world-famous dust covers, I guess I can stop lurking and talk about them a little bit.

The covers are indeed are restrained by a metal rod, which was cut by a dual NSI pyro cable cutter.  The cutter is massive overkill for the job, but....

These dust covers were one of the last things added to the rover.  The MSL HazCams are build-to-print copies of the MER HazCams.  On MER, the cameras were protected inside the lander, and in over 10 rover-years on the ground they haven't seen dust building up enough to be worrysome.  The Skycrane system was supposed to reduce the plume ground pressure during landing to the point where dust wouldn't be an issue for MSL.

But after Phoenix landed and everyone saw the pictures of pebbles *on top of* the pads on the bottom of the lander legs, and the legs themselves coated with a sticky looking layer of dust, some concerned folks looked at the issue more closely.  It turned out there is a core flow in the Mars Lander Engines on the descent stage that stays strong all the way to the surface, even hanging at the end of the skycrane.  And that can kick up a lot of dust+reaction products during the skycrane maneuver, some of which would go back towards the rover.  There was a review of hardware in danger of being coated with "sticky" dust; everything was determined to be dust tolerant *except* the HazCams.

Oh, but the HazCams were already done, and so were their mounting interfaces onto the rover, and the mounting hardware was already built....

I was given the task of working around all the geometric constraints of were the cameras needed to be to do their job, carving out a volume for the covers to open, making sure they end up above the belly pan of the rover so they don't impede mobility after they are open, etc (just finding room for the covers to swing with the vehicle design where it was in late 2009 was....fun).  The covers were a "do no harm" best effort - the idea was not to impact the existing HazCams.  Some of the constraints in that area meant they couldn't be 100% sealed, hence the dust particles that got past them.  But the front images from last night especially showed a LOT of caked-on dust blocking a significant amount of the images - and that's what we were really trying to protect against - caked on dust or impacts from small pebbles damaging the coating on the cameras.

Another consequence of being a late addition to the design was that we didn't have time to procure a custom mini-cable-cutter, and we had to fire something with the same electrical characteristics as a NASA Standard Initiator.  The cutters I used had been ordered for another part of MSL and then went unused because of a design change in that other subsystem.

The cover flips open (in 10-20ms depending on if it's the front or the rear) into a honeycomb energy absorber that bring it to stop with a constant deceleration.  The honeycomb absorbers I used had been fabricated 10 years ago as flight spares for the TES mission and kept in their purge/baked out bags with all the certifications by the engineer who built them.  I went to review my absorber design with him one day, showed him the size and shape, and he said - "I already built that, I have 60 flight certified units in storage". Once the covers are open, the spring force from the torsion springs holds it in place against ever moving again.  Because the springs are oversized to meet design practices for moving mechanism torque margins, they have plenty of torque to simply hold the covers open forever.  No latches or other mechanism needed.

Also, I've moved on from JPL to another company, and when I left my understanding was the the first images *uplinked* would be with the covers open, and the images with the covers closed would be taken but uplinked later, much like the MARDI images.

I guess with the communications window from Odyssey being so tight, they decided to bin down and grab the images with closed covers right away, because the opening sequence might not have completed before the end of the comm window...  So I had no idea my hardware was going to be so famous.  They even made that cool press-release quality animation for the final pre-landing press conference yesterday.

This is an amazing image!  I've always wished for external images of missions; they're rare.  I think video of the entire landing sequence could have been possible too: just before landing (a min. or so?) shoot out a small camera that embeds or otherwise lands into the soil.  Then it tracks and records video--imagine seeing the whole thing in HD.  Would have been incredible, not to mention extremely useful for capturing general public interest...

Not feasible.  The camera would be a lander itself and would require many services.

If the hydrazine was going to be a possible issue why didn't they just pre-command the descent stage to expend all prop and crash ballistically?
That appears to be essentially what they did, and there would still be residual hydrazine in the wreckage.

Not to beat a dead horse here but I am not so sure. The data in hand suggest they had nearly 120kg of Hydrazine remaining nearly 1/4 of margin from the total. That seems like it would provide an awful lot of deltaV especially with out roughly 1 ton rover attached?

The purpose of my inquiry is that a question was asked how far afield the descent stage might have landed and with the extra hydrazine on board is there a contamination issue.

If it did deplete the prop and then crash both of these concerns would be essentially moot but I didn't here Miguel dispel it that in any way. What I heard was that we just tried to get is as far away as possible 100m or so.

In short if anyone has confirmation that the descent stage was commanded to fly until prop depletion I would love to know that. I am with the reporter that asked the original question; seems to me that leaking hydrazine would present a significant concern to the science?

marsman2020, thanks for that great explanation about the covers. Answers my question about why some dust managed to sneak past the covers anyway.

Do you (by any chance) know how well-protected the scientific cameras are?

The cameras on the Remote Sensing Mast (4x engineering NavCams, MastCams, and ChemCam are protected by features in the interface between the stowed RSM and the rover top deck.  The Mars Hand Lens Imager on the turret has its own dust cover with a motor that can open and close it throughout the mission, so it is protected as well.

The main challenge with the HazCams is that they are right at the lower outer edged of the rover chassis, directly in the path of any reflected flow and its associated excavated material from the landing engines during touchdown.  The 4 front cameras are in two interleaved pairs (ABAB) at the center of the front panel of the chassis; the rears are 1 pair on each side of the RTG (AA  ||| BB).  From the pictures it looks like the front covers got hit pretty good with the caked on material, and the rears received a good dusting.

The NavCams can stand in for the HazCams during autonomous navigation if needed, but because they are a different focal length and multiple pictures have to be taken and processed it slows down driving to the point where with NavCams alone, the minimum mission success criteria wouldn't be met.  Also the front HazCams are used to image the workspace of the robotic arm/turret for the operation of the sampling system.  All that payed into the decision to protect the HazCams as best we could.  (I didn't actually make that decision, I just made it happen.)

When the RSM deploys it will take a panorama "self portrait" of the rover and we will have a better idea of what the dust situation is.

The descent stage did not burn until depletion. It just throttled up the four canted thrusters to 100% for 6 seconds, then sent due north and then cut-off the thrusters and then flew on a ballistic trajectory and impacted the surface.

Even just having the covers there and making them clear so we could assess what hit them gives useful information for future rovers.  It was still an open question among some members of the MSL team if they were really "needed" or not.  Even after I built the hardware and tested it many times with an EM HazCam, there was some consternation about putting a pyro so close to the cameras.  This is a good example of high quality systems engineering - taking the lessons learned from another mission (Phoenix) and applying them into MSL within months, even though it caused a lot of heartburn and added cost - because it was the right thing to do to ensure the success of the mission.

Oh, I forgot to add - in the pictures with the covers closed, there are pan head bolts with washers under them that hold the clear Lexan in place with "just enough" force that it can still slide with respect to the aluminum cover structure during thermal expansion/contraction.  One of those is a small Belleville disc spring....that I bought from McMaster-Carr.  It was one of their items that has a materials/lot certification to the relevant AMS spec included, and we did additional materials and force:deflection testing on samples of the lot so my materials engineer would let me fly it.  Since we had those testing facilities in-house, it was less costly and faster to qualify an the off the shelf part (for a low-risk application) vs having a custom run of parts made.

Understood but in this case wouldn't it be safe to assume that a longer burn or maximum burn would have only moved that dispersion farther afield? I can't imagine a scenario where it burns so long and so squirrel-ly that it actually returns "closer" to the landing site?

I recall hearing at one point that the descent stage has a very limited computer capability, so the sequence that it could run after the bridal separation had to be deliberately simple.

The design on MSL was to use the rover computer for everything....  So a more complex sequence for a burn to depletion might not have been an option.

Call it a "concern." It's still a legitimate reason to avoid the descent stage. I haven't heard if they might look for the backshell, heat shield, or cruise balance weights. They also can "scuff" the soil with the wheels to get shallow trenches to examine.

The criteria here is basically better safe than sorry. SAM contains several very sensitive instruments...far more so than anything on the MER's. The value of that sensitivity is compromised if you detect something that just as easily could be from the descent stage as from Mars itself.

Then what was the purpose of that video?

He was joking. We'll see it in a few days. It provides local context of the landscape around the lander. This will help the science team plan the initial drives based on what appears interesting or challenging in higher resolution than what can be seen from orbital images.

Very informative post. Thanks!

I think I found a spec sheet for the NSI:
www.hstc.com/Download.aspx?ResourceId=28223

There's actually not much propellant in it - almost all of the volume of the NSI is the housing and the electrical connector.

In your application does it cut by mechanical overload, or burning through the pin?

Oh, but the HazCams were already done, and so were their mounting interfaces onto the rover, and the mounting hardware was already built....

I was given the task of working around all the geometric constraints of were the cameras needed to be to do their job, carving out a volume for the covers to open, making sure they end up above the belly pan of the rover so they don't impede mobility after they are open, etc (just finding room for the covers to swing with the vehicle design where it was in late 2009 was....fun).  The covers were a "do no harm" best effort - the idea was not to impact the existing HazCams.  Some of the constraints in that area meant they couldn't be 100% sealed, hence the dust particles that got past them.  But the front images from last night especially showed a LOT of caked-on dust blocking a significant amount of the images - and that's what we were really trying to protect against - caked on dust or impacts from small pebbles damaging the coating on the cameras.

Another consequence of being a late addition to the design was that we didn't have time to procure a custom mini-cable-cutter, and we had to fire something with the same electrical characteristics as a NASA Standard Initiator.  The cutters I used had been ordered for another part of MSL and then went unused because of a design change in that other subsystem.

The cover flips open (in 10-20ms depending on if it's the front or the rear) into a honeycomb energy absorber that bring it to stop with a constant deceleration.  The honeycomb absorbers I used had been fabricated 10 years ago as flight spares for the TES mission and kept in their purge/baked out bags with all the certifications by the engineer who built them.  I went to review my absorber design with him one day, showed him the size and shape, and he said - "I already built that, I have 60 flight certified units in storage". Once the covers are open, the spring force from the torsion springs holds it in place against ever moving again.  Because the springs are oversized to meet design practices for moving mechanism torque margins, they have plenty of torque to simply hold the covers open forever.  No latches or other mechanism needed.


Excellent explanation and thank you for "covering" us.

This is an amazing image!  I've always wished for external images of missions; they're rare.  I think video of the entire landing sequence could have been possible too: just before landing (a min. or so?) shoot out a small camera that embeds or otherwise lands into the soil.  Then it tracks and records video--imagine seeing the whole thing in HD.  Would have been incredible, not to mention extremely useful for capturing general public interest...

Not feasible.  The camera would be a lander itself and would require many services.

Fair enough, but I'm thinking to keep it very small and simple since it's not mission-critical.  All we need is a way to eject it safely, and then perhaps its own engine fires it down into the ground, so it hits before the rover.  Think of a model rocket. 

So if it's a tube then, it just drives itself into the ground, with the camera left sticking out at the end.  This should be easy to refine and test on Earth, and the entire thing is self-sufficient with battery power.  Then much later as time permits, it transmits its data back to the rover.  It would be also invaluable I would think, to have external video of the rover driving around, from say 200' away!  Of course then it will drive up and say hello.  :)

I was personally happy to see all the live coverage, images+ photo of the landing from orbit. I came to realization (well, I always knew about that, but hm.. never actually thought about it) that new technology is really advanced. This skycrane looks crazy and suspicious, but it's much more elegant than past landing systems like the one of Mars 3 employing plastic foam for landing cushion.

Expansion on the night-time operations response while robertross keeps up with the Q/A:

The response was basically that it takes more energy to operate at night due to need to turn on heaters to various system, so operations are best done during daytime to keep within the 2080 Watt-hour per day constraint.

As they characterize the RTG performance on-location, they may be able to start budgeting more than 2080 Watt-hours per day, but not right away.

So if it's a tube then, it just drives itself into the ground, with the camera left sticking out at the end.  This should be easy to refine and test on Earth, and the entire thing is self-sufficient with battery power.  Then much later as time permits, it transmits its data back to the rover.  It would be also invaluable I would think, to have external video of the rover driving around, from say 200' away!  Of course then it will drive up and say hello.  :)

No, it wouldn't be that simple.
a.  It would still need to be a "lander" even to stick in the ground.  Would need a rugged camera.
b.  how is it going to track the lander?  there is no GPS on Mars and still how is it to find the lander?
c.  Now you are adding more weight,  systems and resources to the rover by adding a receiver, in addition to the camera system
d.  There is no value much less invaluable to have external video.  It serves no useful service with only more cost.

No, this is not a good idea

Well, since I was the cognizant engineer on these now-world-famous dust covers, I guess I can stop lurking and talk about them a little bit.


I found a cool video showing your cover opening. I'm sure you're very familiar with this particular video.

http://mars.jpl.nasa.gov/multimedia/videos/movies/hazcamatlo20120803/hazcamatlo20120803-1280.mov

I've actually moved on from JPL to another company now, so the first time I saw it was yesterday morning with everyone else at the pre-landing briefing.  They missed one solid body in the animation (there is a "base" to the covers that surrounds the lenses on the HazCams) but it was really cool to see that they made a press-quality video of it!  The 10+ minute MSL Mission animation was made using an in-development version of my CAD models, and doesn't show the covers deploying.

It's a lot more impressive at 4000 fps.   ;)  We did several videos of that to check that my estimates of mechanism friction were correct by measuring the time for the covers to open. 

Well, since I was the cognizant engineer on these now-world-famous dust covers, I guess I can stop lurking and talk about them a little bit.

The covers are indeed are restrained by a metal rod, which was cut by a dual NSI pyro cable cutter.  The cutter is massive overkill for the job, but....

Very informative post. Thanks!

I think I found a spec sheet for the NSI:
www.hstc.com/Download.aspx?ResourceId=28223

There's actually not much propellant in it - almost all of the volume of the NSI is the housing and the electrical connector.

In your application does it cut by mechanical overload, or burning through the pin?

If you look at this paper on MER - http://articles.adsabs.harvard.edu//full/2003ESASP.524..387B/0000388.000.html - it shows in Figure 2 a 'Y' cable cutter (I believe the first version was used on Surveyor, or so my Pyro Engineer said).  That's basically what I used.  The 2 NSIs create hot gas which pushes a blade forward, cutting the target, and striking an anvil.  In most applications this is used as a cable cutter with a stainless aircraft cable, but I used a solid rod made of the same material as the covers and cover base so that the rod would expand/contract the same amount as the cover assembly over the wide temperature range we had to design for on MSL.  My pyro engineer found reference to the same cutter being used on Pathfinder to cut a solid rod of the appropriate material, with the associated qual testing, so we used that cross sectional area for the rod on the covers and carried forward the work that others had done already.

This is an amazing image!  I've always wished for external images of missions; they're rare.  I think video of the entire landing sequence could have been possible too: just before landing (a min. or so?) shoot out a small camera that embeds or otherwise lands into the soil.  Then it tracks and records video--imagine seeing the whole thing in HD.  Would have been incredible, not to mention extremely useful for capturing general public interest...

Not feasible.  The camera would be a lander itself and would require many services.

Fair enough, but I'm thinking to keep it very small and simple since it's not mission-critical.  All we need is a way to eject it safely, and then perhaps its own engine fires it down into the ground, so it hits before the rover.  Think of a model rocket. 

So if it's a tube then, it just drives itself into the ground, with the camera left sticking out at the end.  This should be easy to refine and test on Earth, and the entire thing is self-sufficient with battery power.  Then much later as time permits, it transmits its data back to the rover.  It would be also invaluable I would think, to have external video of the rover driving around, from say 200' away!  Of course then it will drive up and say hello.  :)

That sounds like Deep Space 2. (http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=DEEPSP2)
Let's stick with astounding success, and remember better is the mortal enemy of good enough.
Please add my congratulations to those already heaped on the JPL team.
And now back to updates and downloads.

Congrats to the JPL team and the folks here for a great thread on a marvelous achievement. I have nothing really to add here except for one comment: In celebrating this great achievement JPL and NASA have to find a way to leverage its success politically.  Part of that work includes changing how projects like this are planned for, budgeted, and sold to Congress. 

MER was full of controversy for years before launch because the low-ball budget for the mission from JPL/NASA got accepted by the Congress, then the cost of the project grew almost as fast as Kudzu grass. There was a lot of discussion about killing the whole project IIRC. The rapidly inflating cost of the rover and it's unique way of doing things ran into many hurdles, including the nuclear power generator it has.

For great projects like this to continue happening, and to rescue things like the Webb Space Telescope from the budget knife, NASA has to get its act together and find a way to sell people on what it can do, if given time, money, flexibility, and by earning trust by being honest about programs like this. the alternatives are either no programs, or trying to work with 4 or 5 five other entities on projects like this, which won't work to save money in the long run (contra Adm. Bolden's remarks at the press conference). NASA can still do great things if its allowed to do them. 

Thanks for the coverage, and congrats to NASA! Can't wait to see we find out there.

You know, if you gave them realtime video feed, they'd be complaining about getting it 14 minutes later than folks on the other side ;)

If the hydrazine was going to be a possible issue why didn't they just pre-command the descent stage to expend all prop and crash ballistically?

They wanted to do a known maneuver and not worry about dispersion.

Understood but in this case wouldn't it be safe to assume that a longer burn or maximum burn would have only moved that dispersion farther afield? I can't imagine a scenario where it burns so long and so squirrel-ly that it actually returns "closer" to the landing site?

There are four engines - where will it end up if they don't all burnout at the same moment?

Eight engines in four pairs.

But your point stands.  :)

The flight computer remained on the rover.  The engine management computer did the fly-away, so it had to be kept as simple as possible.  Don't worry about how much fuel is left, or what altitude you're at, just tilt north and give 6 seconds of omph. Ther'll be no time to get far enough off course to need any steering.  Elegant and simple.

Considering the dust we've already seen I think the skycrane was a good choice.  With humans at least they could clean the dust off the instruments.

The skycrane didn't replace rockets....  it just made the lander land at a height of 21' above ground level, avoiding backwash (easier to control) and dust (keeping things cleaner), and simplified the separation of the motors and tanks (to save roving weight) to a single cut of a tether.

The tanks are expected to burst, I presume?  I quite realize that early missions need not conform to "EPA" standards, nor am I claiming that they should have in this mission.  Still, I would have rather seen it land upright, in a controlled and predictable fashion.

That data would have been far more informative for future missions.

In the larger picture of HSF and even unmanned exploration, we've continued to dispose of hardware, while wondering at the incredible unsustainability of all space exploration, manned and unmanned.  If we never "start thinking" about re-usability, it will never happen.

The truth is, as I see it, after forty years of putzing around in space we don't even attempt re-usability.  It is not the case that we can't do this, due to some law of physics.  It is not the case that re-usability will be "easy".  It is the case that reusability will be necessary for humanity to maintain a permanent presence in space.  The time to start thinking about this is now.

It was an honest question which you didn't even attempt to answer but also snarkily pointed at JWST. It's very easy to sit here and contemplate such feature creep. Everything costs money. Armchair engineering is the easiest.

You can argue semantics if you want. Trying to levy a reusability requirement on a Mars lander at this point, when each additional kilogram of mass delivered there costs millions is ludicrous, IMO.

Think about what you were asking for:
Still, I would have rather seen it land upright, in a controlled and predictable fashion.

Prior to this, guided entry on Mars was undemonstrated. The parachute as the biggest supersonic parachute ever and it couldn't have been tested at the specified Mach number on Earth. The skycrane maneuver was undemonstrated. Among all that, you'd also love to have the descent stage do a nice flyaway and a soft landing? Who pays for that capability and for what purpose on this particular EDL?

It should be clear that I'm not levying a new requirement on the vehicle, I'm talking about the larger issue of re-usability, in general, while using this vehicle as a convenient case in point, because of its topicality.  My larger point holds.  At least Mr. Musk agrees with my thinking about re-usabilty.

Prior to this, guided entry on Mars was undemonstrated. ... Among all that, you'd also love to have the descent stage do a nice flyaway and a soft landing? Who pays for that capability and for what purpose on this particular EDL?

Yeah, it would have been a "nice to have".  But I didn't invent that budgetarily expensive and mission creepy phrase.  Even so, the purpose would have been pretty clear: Demonstrate a controlled landing.  Clearly a useful demonstration that will have to be made in due course.

Excuse me for a minute tho.  I gotta adjust my armchair.
