Genesis Capsule Crashes; Chutes Blamed 656

Cyclotron_Boy writes "The Genesis probe (reported here) has crashed to the ground, near a road in the Utah desert. The stunt chopper pilots were not to blame, though. The drogue chute didn't open on re-entry. NASA TV is covering it currently. The choppers have landed near the probe, but no word yet as to the condition of the space dust." Many readers have also pointed to CNN's coverage. Update: 09/08 16:39 GMT by J : MSNBC has more coverage and a sad photo of the half-buried capsule: "The capsule broke open on impact. It was not yet clear whether the $260 million Genesis mission was ruined."

    Here are some relevant quotes from the Spaceflight Now play-by-play [spaceflightnow.com]. It looks like there were a number of things that could have gone wrong. Let's say it again, class... "Space Ain't Easy."

    * Starting about 1045 GMT, the spacecraft spins itself up to 10 revolutions per minute. The spinning will provide the unguided sample return capsule with additional stability during entry. The spacecraft then rotates to the proper orientation for release and spins up to 15 revolutions per minute.

    * Genesis will be stabilize with its nose down because of the location of its center of gravity, its spin rate and its aerodynamic shape.

    * About 45 seconds after entry interface, the capsule will be exposed to a deceleration force three times the force of Earth gravity, or 3 G's. This arms a timer that is started when the deceleration force passes back down through 3 G's. All of the parachute releases are initiated from this timer.

    * After one minute of atmospheric descent, the capsule should be at an altitude of 197,000 feet [...] Slightly over 10 seconds later, the capsule will be exposed to about 30 G's, the greatest deceleration it will endure during Earth entry.

    * 1554 GMT (11:54 a.m. EDT)
    The capsule has been spotted high over the planet!

    * 1557 GMT (11:57 a.m. EDT)
    The capsule appears to be tumbling!

    * 1557 GMT (11:57 a.m. EDT)
    The Genesis sample return capule is rapidly tumbling with no chute.

    * 1558 GMT (11:58 a.m. EDT)
    IMPACT! The capsule has slammed into the Utah desert after failing to deploy its chutes and parafoil.

    * 1604 GMT (12:04 p.m. EDT)
    Mission control says without the drogue chute and subsequent parafoil, the capsule would hit the ground at about 100 mph.

    * 1610 GMT (12:10 p.m. EDT)
    Recovery forces are moving toward the capsule, which has made a very spectacular crater.

    (Disclaimer: I posted this in the pre-impact discussion as well.)

      A crash landing, even at the capsule's relatively slow speed of 9 mph, could ruin some of the data collected during the mission. from CNN piece

      A very likely cause is that the tumbling cause the decelleration sensor to be incorrectly oriented. The trigger for the parachute sequence is almost certainly a single-axis accelerometer, and if the capsule is not aligned properly, it will never see the proper acceleration, and this never trigger the sequence.

      There is absolutely no indication that the sequence ever started. The heat shield is still attached, and none of the recovery system covers separated before impact.

        I thought it was interesting that the acceleration has to go past 3 gees to *arm* the device, then back below three gees to actually *deploy* it. Miss #1 and you don't get armed, and you leave a crater. Miss #2 and you get armed, leave a crater, *and* a little surprise for the recovery crew. Is this a new design, I wonder, or is this a tried-and-true method that's worked better than anything else so far?

          That sort of sequence is not uncommon (assuming you consider that there haven't been a lot of automated, unmanned planetary entries since the 60's). It ensures the various parts deploy based on external conditions, not on a pre-set timeline (which could be off by minutes). High G's = reentry has started, reduced G's = dynamic pressure is low enough to safely deploy the drogue. Then deploy the main based on either the tension on the drogue chute line, or time.

            Makes perfect sense, but also makes you wonder just how difficult it would have been to install an "Oh Shit" remote trigger, just in case. I mean, a 200+ million dollar project might need a little manual intervention.

            The stunt team could have hit a big red button, causing the probe's parachute to deploy, then swoop down for the capture. The whole mission seemed kinda wacky in the first place, with the helicopter and all. I wonder who sat down and decided it'd be a good idea.

            Also you have to wonder HOW the damn thing hit land to begin with. Isn't 70% of the Earth's surface covered with water? You have a 3 in 10 chance of hitting land if this is true.

              Because they aimed.

              It's not as though we just deorbit stuff and pray like hell that it lands somewhere reasonable. This is why we had ships hanging around where our early capsules landed, why the Russians could get their capsules to land in Russia, and why the Shuttle, when not exploding, lands safely at any of a few predictable locations.

              We certainly don't have a worldwide sky of helicopters, so they'd better well have aimed this thing towards the few (or one) copters they had to capture it.

              It's not that hard.

              It's only when we're not carefully controlling things -- like meteors, Skylabs and such, that they land all over the place. And even then we can make some guesses.

                Only during a very short period of time while you pass through the ionosphere. It's called an ionization blackout and is caused by hot, ionized gasses in the upper atmosphere. If you stand outside at night and see the aurora borealis... same thing, basically.

                Once you have passed into an area of denser atmopsphere, radio communication becomes possible again. The Apollo, if we use that as a guide for where parachutes would typically be deployed, deployed its chute at about 25,000 feet (about 7.6 km). The ionosphere starts at about 260,000 feet (about 80 km). Now I'm not saying that parachutes wouldn't be deployed higher for something trying to land on land, but not ten times higher....

          The guided missile I worked on used a S and A Safety and Arming, device not unlike what is described. The "warhead" is only armed after the missile achieves a classified amount of acceleration for a period of time. This is needed to insure that the "warhead" doesn't detonated at an unsafe distance from the launcher.
          It is preferable to have a spacecraft auger into the dirt, than have a parchute deploy on launch and possibly pulled the launch vehicle into a populated area.

      Interestingly, when I was watching this live over the internet, they appeared to go to a picture of the capsule underneath a canopy, in a very grainy b/w sequence that lasted just a few seconds, then they switched to another camera, and later said they didn't yet have visual on any chutes.

      BTW, I did catch the LAT/LON, they said it was 40 07 40 and 113 30 29, that would actually show up in China. If you say -113 instead of +113, you get a location in the Deseret Test Center. Here's a Mapquest map [mapquest.com]. They also said it was "just north of the road." Of course, they could have accidentally or deliberately been a bit off on their coordinates, but this is what they said.

The spacecraft then rotates to the proper orientation for release and spins up to 15 revolutions per minute.

      When I was watching the thing via the long-range camera on NASA TV, it looked to me that, even when the capsule was just a bright dot with changing luminosity, it was spinning at much higher than 15 rpm. More like 60 - 80 rpm. At that point, I figured what I'd see next...

        If it were spinning the way it was supposed to, you wouldn't have been able to see it: it was supposed to spin neatly around its axis, for stability. (Like a flying saucer spinning)

        Instead, it lost aerodynamic stability altogether, and started tumbling randomly in all directions, which is what you saw. I think once it started tumbling, all hope was lost, since the G-forces of re-entry were jolting the insides in all different directions as it tumbled. Some of those forces might have been even higher than what it encountered on impact.

        (i.e. you don't want to be spinning in different directions as you're doing a 30-G descent) :(

      RobertB: You are so right about these projects not at all being easy.

      They are at the cutting-edge of cutting-edge technology.

      I noticed one poster joking about NASA having a 0.500 batting average. You know, when you consider what kind of game NASA is playing and the complexity of the playing field, 0.500 sounds damn good to even me, and they have been doing a helluva lot better than that.

      I think you must have worked in the arena in the technical area to have had the insight on just how complex the issues are. Very few can appreciate the job JPL/NASA have done until they have been intimately involved in it. Once someone comes to term with the complexity and the unforgiving realities of natural laws governing mission success or failure, one understands why engineers and scientists cannot always be the obedient underlings the Dan Goldin types would like us to be.

      Even with our best work, we cannot guarantee success - all we can do is get the statistical weights of success more in our favor. Even with our utmost care and attention, there are still so many things that can possibly go wrong.

      Like anything else though, even if the thing we worked on failed, we still learn a helluva lot on how to do it better next time.

      To me, the greatest tragedy is when we lose one of our guys, through accident, layoff, or retirement, because that represents a total loss of all the accumulated experience of that individual. Everything else can be replaced, but the experience and knowledge gained from it is priceless.

        It's because of Apollo.

        Even without considering the technology difference between now and 1960's, this is a relative cakewalk to the miracles they performed in getting Men to and from the moon several times without a single fatality.

        And when you consider the difference in materials and instrumentation, it's an even worse comparison.

        NASA maybe be underfunded, but they are still screwing up on the things they are doing. We are beyond the point at which bringing an unmanned satellite down from orbit should be troublesome.

    I'd much rather NASA send up three cheaper/faster/riskier missions of which one crashes and two succeed, than send up one bullet-proof mission. So don't jump all over NASA for screwing up. If they didn't screw up now and again (on this type of mission), then they were clearly playing it too safe.

    ...the helicopter pilot would have seen the problem, matched courses with the probe, and sent his chopper into a 100 MPH dive parallelling the probe. Someone on board would have tied a rope around his waist and leaped out, freefalling, and grabbed the probe. All the time the pilot would have been shouting out the altimeter readings... 10000 feet! 9000 feet! 8000 feet!

    They would have gotten the probe on board just in time for the pilot to pull out of the dive one foot above land. Then as soon as they brought the probe back to base and got it out of the copter the charge would have gone off and the chutes would blast into the air, leaving the scientist member of the team covered with soot, while everyone laughed.

    FYI, there's going to be a press conference at 2:00PM EST. I know at least CNN will be covering it, for those of us who don't get NASA TV.

    We were watching it live in the NASA cafeteria (GSFC) at lunch time on the tvs.. silence.. camera follows, follows, follows.. then the best collective "OH SHIT!" ive heard yelled in years. Then the cooks came out to watch and gave the best "Damn y'all dun fucked up huh?" look ive seen in years.

    According to NASA's NSSDC master catalog:

    There was some concern that the sample return capsule battery would fail, jeopardizing the re-entry. The battery was overheating, but ground tests have shown that the battery should be unaffected by the amount of heating it has endured, and should operate to deploy the parachute on reentry.

    Damnit, I must have misplaced a decimal point or something. I always do that I always mess up some mundane detail.

    Oh, this is not a mundane detail, Michael!!

    From TF CNN A:

    This daring retrieval method will protect the samples and sensitive instruments during reentry. A crash landing, even at the capsule's relatively slow speed of 9 mph, could ruin some of the data collected during the mission.

    Considering the fact that it hit the ground at about a 100mph, when a crash landing at even 9mph was considered dangerous, it is very likely that most of the instrumentation and data is ruined.

    Hopefully the canisters (or the like) containing the samples survived the ride. The helicopter "snatch" strategy sounded hit-and-go to me anyway, but then I'm just an ignorant computer scientist.

    I'm admittedly largely ignorant of the Genesis project and the issues recovering it, but...

    Couldn't they have possibly gotten that probe into an orbit that a shuttle could have matched, and recover the probe that way?

    Granted, it could be a while before a shuttle could be tasked to such a recovery, but one could think they could put the probe into a reasonably stable orbit to wait until that time.
    • Couldn't they have possibly gotten that probe into an orbit that a shuttle could have matched, and recover the probe that way?

      Of course, but then the cost would have been closer to $1B instead of $260M.

      I'm sure their second attempt (total cost including $260M attempt still under $600M) will be better.

    This from MSNBC: "It picked up speed rapidly as Earth's gravitational pull brought it closer, reaching velocities of 25,000 mph or 11 kilometers per second. The capsule's descent was then slowed somewhat by atmospheric re-entry." They then forgot to mention that it hit at only 100mph. I'd say hitting the ground at 100mph was just barely a "slowed somewhat". No one could ever accuse the media of overexagerating the facts!

    In the old days before video spy satellites, film canisters were recovered by helicopter snatching of parachutes. Its a well-tried technology.

    The reports that the re-entry vehicle was seen to be tumbling rather than spinning properly makes me wonder if sloppy thinking about rigid body kinematics [csuchico.edu] came into play yet again? Spinning objects often behave in tricky, counterintuitive ways, and even in a mission of this scale it would not be too surprising to find that the spacecraft tumbled when the engineers intended it to spin smoothly.


    If true, it would not be the first time -- by a long shot -- that the strange behavior of spinning objects caused trouble for a spacecraft. Some of the early three-axis-stabilized satellites were made into inadvertent spinners after their launch stabilization spin made them flip upside down (so that their de-spin rockets made them go faster instead of slowing them down!). SOHO [nasa.gov] was nearly lost in 1998, in part because rotational precession rotated the craft so that the solar panels were in long-term twilight.


    Here's hoping there's something left for the team to analyze. Three years in space plus ten years of planning and lobbying is a long time to wait.

    Beagle cratered.
    Beagle2 cratered.
    Spirit captured the flag!
    Opportunity captured the flag!
    Genesis cratered.

    I think NASA is still in the lead. :)

    From the medial package:

    "Lockheed Martin Space Systems, Denver, Colo., designed, built and operates the spacecraft, and is overseeing the capture and return of the Genesos sample capsule."

    I say that, since we're all about accountablity, that Lockheed Martin pony up the cash they lost through insufficient engineering. It doesn't matter whether is shipped on time, in budget, with purple wings, whatever - the fact is that it failed. If we pay L-M, it will be an indication that the Federal Government is simply handing checks over to corporations.

    On a side note, I happen to know both Alphonzo Diaz and Orlando Figueroa, though I was sufficiently separated from them by management layers that I'm sure they don't remember me. They were both pretty nice guys. It's a shame this didn't work out for them.

Sentient plasmoids are a gas.
