Lunar Lander Challenge Ends in Fire, Disappoinment 123

Posted by CmdrTaco from the fire-go-boom-boom dept.
mikesd81 writes "The rocketeers at Armadillo Aerospace, thwarted by engine problems and other mechanical failures, left this year's X Prize Cup empty-handed after their spacecraft burst into flames on liftoff Sunday. An attempt on Sunday to hop from launch and landing pads ended with the MOD craft bursting in flames shortly after engine ignition. This is the team's second attempt at the challenge in New Mexico, they were the only entrant in last year's event, which they also lost. Brett Alexander, Executive Director of Space Prizes and the X Prize Cup relayed a comment from John Carmack, leader of the Armadillo team: "Today is officially a bad day when it comes to our vehicle." The last attempt to win the $350,000 Level 1 prize on Sunday ended when the MOD vehicle had an engine fire, with pieces coming off, including disconnected cabling. Clearly, there was a fire on the pad that burned for a while — but then went out. The Armadillo team called a safety emergency, requesting fire truck assistance, Alexander said."

        FYI, the Soyuz flight where the three cosmonauts died on re-entry was due to a mechanical malfunction of a valve that connected the re-entry capsule to the rest of the Soyuz spacecraft. It was not an error on the crew's part. In fact, one of the crewmen actually had just enough time to unbuckle, crawl beneath the seat and close the valve halfway before passing out. Rather tragic.

        The Soviet space program is as full of accidents or more so than our own. It really is tough business:

        Yuri Gagarin's Vostok 1 capsule remained inadvertantly connected to it's service module during re-entry due to a bundle of wires (I assume a pyro failed to fire). It caused the spacecraft to wobble marginally out-of-control until the wires burned through.

        After a series of problems in-flight led to a decision to delay the Soyuz 2 launch (probably fortuitiously, since 2 would've had the same issues), the Soyuz 1 main chute didn't deploy and the backup chute tangled. The cosmonaut died when the capsule hit the ground. Interestingly, it launched under political pressure, and Gagarin had tried to get himself scheduled for the flight, believing the politburo would then listen to the engineer's concerns rather than risk losing a national hero.

        All four N-1's (the Soviet's planned moon rocket) exploded during launch (unmanned).

        A Cosmos rocket exploded on the pad in 1973, killing 9 engineers.

        In 1975, Soyuz 18a went out of control 5 minutes into launch, causing the launch escape system to activate. This saved the crew, but barely. They experienced accellerations up to 21 g's, and the capsule landed in the mountains in NW China. One article claims the capsule would've tumbled off a cliff if the chute hadn't snagged on a tree, but I haven't seen that verified.

        Soyuz 23 in 1976 crashed through a frozen lake and sank with the crew inside. Remarkably, the crew was saved after considerable effort when a diver attached a cable that allowed a helicopter to lift the capsule out.

        A 1980 explosion of an unmanned Vostok rocket on the pad killed 48 people on the ground.

        In 1983, Soyuz T-10 caught fire on the pad. Ground control triggered the launch escape system, pulling the two men and their capsule clear. The rocket exploded two seconds later, but the cosmonauts survived.

        There was a fire aboard the Mir in 1997. The same year, a Progress cargo ship collided with the station and punctured one of the modules. The crew had to rush to close the hatch to the module.

        In 2002, an unmanned Soyuz rocket exploded, killing a Russian soldier.

        One thing few people realize is there have been nearly as many close-calls in the US space program. Everyone knows about Apollo 13, but the first shuttle launch had a near burn-through due to tiles that fell off during launch. Another shuttle flight had an engine shutdown due to a short circuit that left it in a low orbit. Apollo 12 was hit by lightning. One of the Gemini flights went out of control and tumbled violently, nearly killing Neil Armstrong and David Scott. The Mercury 4 capsule had a hatch blow prematurely on splash down and sank as Gus Grissom scrambled to escape.

        All of these guys, US, Russian, and Chinese alike have a lot of guts.

While the race teams strive to get the cars as fast as possible, NASCAR's engineering (at the circuit level) appears to be dedicated to "making the race more competitive." That means SLOWER cars (see "restrictor plate," "aero package,") and rigid specifications on how the cars can be engineered and set-up.

            Contrast this with something like F1 where it really is all about the technology, and it's downright silly to describe NASCAR as the apex of automotive engineering.

      Hey,

      I went to Alamogordo to watch the competition. As a graduate student in Albuquerque, the 3.5 hour drive was worth it. As the previous poster commented, the Saturday flight was ALMOST successful. The first transition from pad to pad did not have any problems at all. The hovering lander was a very interesting sight to see above the desert. Due to safety issues, the viewing area was too far away to get a good look when the lander was close to the ground. However, a large video screen broadcast the images.

      When I was standing there, watching, it was unclear what actually caused them to fail to meet the objectives. I thought the lander actually made the time limit on the return trip but did not land successfully. I thought it tipped over, or something broke off when it came down. However, I was unable to clearly see and my experience was based on a what people were saying over a loud speaker and the images of lander in a dusty cloud on a giant screen. It is interesting to read that they actually did not meet the time limit. I wasn't able to see the Sunday launch.

      Overall, I will probably continue to support the competitions. Many people in New Mexico are excited about developing a consumer space industry, myself included. The air show had about the same excitement pattern as a baseball game, very exciting for a small portion of the time and a lot of waiting. I hope that the guys at Armadillo Aerospace know that everyone is rooting for them.

    Pete Worden, a Lunar Lander Challenge judge - and director of NASA's Ames Research Center, told SPACE.com that the engine blew up, with the rocket's engine chamber tossing out pieces onto the pad. "It's over for them for this X Prize Cup," Worden said. But he added: "I do think they are getting there...it's a robust design.

    That's one exciting definition of robust :-)

      Well, to be fair - they team didn't have the engine they wanted and the parts were sub-quality. They went ahead with the challenge knowing this. Their previous attempts have shown very impressive engineering - but had software glitches in the abort system. Testing that system is incredibly difficult - as you only get to test it when something goes really bad.

      • Why don't they just make a solid engine burning APC? I will never understand the fascination with complicated liquid fuel systems.

        I am not a rocket engineer, but I believe the answer to that is restart capability. Solid boosters go off once. If you're trying to start and stop the craft, it's a problem.

        • I don't see much starting and stopping going on to get to the moon. Granted you will need some throttling capability but on a much smaller scale.

          • Solid engines can't throttle. They've got two settings: off, and full power. And once they're lit, they're at full power basically until they run out of fuel to burn. There's a few things you can do to throttle them, but all of them are really hairy and complex. Basically, solid rockets are good for getting you up, not so good for getting you back down in a controlled manner.

      • While at first I hesitated to reply to "P3NIS_CLEAVER", there are a few reasons why:

        1. the competition is to launch up, pitch over and translate, and land on another pad. Refuel and repeat. Good luck getting a solid engine to throttle nicely. Yes, the Army does it with pintle engines. But it is a far cry from uncomplicated.
        2. Mechanics of a solid: thrust is (for a zeroth order analysis) proportional to the surface area burning. While you can make a flat burning solid (by having a cylinder with a moon or

    Inevitably, some "real" engineers will comment on this story and make snide armchair hindsight comments, with the overall point that it really does take a billion dollars to do rocketry.

    Some points:

    1) These are R&D vehicles. They are not production vehicles. Don't judge what production reliability will be like based on R&D.

    2) They may not have made it over the finish line, but they are the only ones who entered the race among ten or so teams. Many of the teams said they were "close" last year, yet still couldn't make it work a year later.

    The real measure of how successful Armadillo is going is the how easy they're making it look in their videos. But it's not easy, and the fact that they're the only one that's flying hoverable rockets on a weekly basis proves it.

    One of the things that bugs me the most is when Aerospace engineers tear down what they're doing, implying they could do it better, if they only had Armadillo's money. Lots of people have money, but lots of people are also not making Armadillo's progress -- with volunteers, working two days a week.

      uhh this is /., everyone here gives Carmack his due props. and im not saying anything bad about the guy but as ive been saying for the past few months, i think he was overly zealous in regards to implementing quad damage as such a early stage in development.
    • I agree. Just imagine the steps it would have taken to get from Goddard's rocket experiments to the Titan/Atlas if we didn't take advantage of a sudden influx of German rocket scientists and technology after WWII.

      Their problem is that they are (mostly) a bunch of software guys that think they can cobble some hardware together and make it work with a complete lack of engineering rigor. You can't deny their persistence and the amount of success they have earned over the years. If you take a look through their weblog, though, you will see tons of shoddy workmanship, even on elementary, low-tech stuff like wiring. They've got the engines themselves to a reasonably advanced stage of development but everything else is cra

      There's a local (Colorado) team that has a vehicle and they felt it ready to enter, but (per the newspaper report) couldn't get the requisite FAA flight approval. (Sorry, don't recall whether it was Paragon or Micro-Space).

      • Well, as I understand it each of the vehicles would have needed an FAA waiver to do free flights over a certain altitude or duration anywhere in the US. (I don't recall the limits, but I think it's in the Armadillo news archive somewhere.) So if they didn't have an FAA waiver, that (presumably) means they had never done a free flight of anything close to LLC1 parameters.

        That makes it seem pretty unlikely (to me) that they stood a realistic chance of a prizewinning day at the XPC, or that the paperwork was t
