Lunar Lander Challenge Ends in Fire, Disappoinment 123
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."

Lately, they have been flying reliably, but then they had to change the graphite chambers suddenly because the company they bought them from had received a big order and could not supply them to Armadillo. Is that what caused the problems? In any case, making changes just before the big show is always an omen for troubles (not that they had a choice). That may have been it, though there has been some talk about the fuel mixture as well. I guess there's no "standard" for fuel mixtures, or at least, not the kind they use, and the supplier may have changed the mixture slightly? I'm sure John and the rest of the crew will dissect, diagnose, and post the findings..

Yeah, it looks like landing is definitely a tough one.. My guess is that the upward thrust, combined with the sudden outward forces induced when getting closer to the ground, causes some problems with the vertical landing. Seems that as they approach, the vehicle starts tilting a bit..
Hmm.. I thought that, as the vehicle touches the ground, you get a pivotal point and the rocket just tends to top over.
He sounded pretty disappointed... Went as far as saying that they felt worse than last year.. I think it was just a bad day.. Sure, improvement will definitely help, but there are always those days that nothing goes right.. That said, they did have some decent flights earlier.. And, the AST qualification flight went off without a hitch.. There's video here : http://media.armadilloaerospace.com/2007_10_21/modFreeFlight.mpg [armadilloaerospace.com]
That's understandable. They were ready. They had done dress rehearsals of the flights, and it went flawlessly. Everybody is certain it will work. Then they go on stage, and everything goes wrong. Suddenly all that confidence is gone. There's nothing as frustrating as that... I just hope they get over it quickly, and will be back next year - with a vengeance :).

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.

I think it was 83 seconds (7 seconds short!), but it's also worth noting that they did the return flight with a fist-sized hole in the graphite engine. John decided to try the return flight by flying it over really fast, then hovering above the ground a few meters so if the engine finally quit, it would only fall a short distance. Flying with that much damage is amazing enough, but I also find it interesting how easily the rocket is programmed to do whatever Carmack wants, with such control.

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.
