The sad part was the lander was seemingly doomed from the start.
Armadillo Aerospace, led by gaming legend John Carmack of id Software fame,
tried valiantly to win
the X-Prize as the sole competitor in the field.
The X-Prize, a long standing competition, aims to provide monetary rewards to design teams who successfully complete a space or space-related challenge, as well as other challenges that aim to benefit mankind. It is run by the X-Prize Foundation.
The most famous X-Prize event has been the Ansari X Prize event, which gave a $10 million USD prize to the first team to complete a successful suborbital flight. The award was eventually won in 2004 by the SpaceShipOne team led by Burt Rutan and financed by Microsoft co-founder Paul Allen. This team would go on to found Virgin Galactic with billionaire Sir Richard Branson.
Armadillo Aerospace, which also competed unsuccessfully in the Ansari X Prize, aimed to win the new Lunar Lander Challenge. The challenge was sponsored by Northrop Grumman.
At stake was a $350,000 USD purse, for the Level 1 challenge, which as the sole competitor was theirs to win or lose.
The Level 1 challenge required the team to launch a rocket from a designated launch area, reach an altitude of 150 feet (50 meters) and then hover for 90 seconds while landing precisely on a landing pad nearly 330 feet (100 meters) away. The flight then would be repeated in reverse - and both flights, along with all of the necessary preparation for each, had to take place within a two and a half hour period.
Originally four teams had planned to compete,
, but the other teams were not able to produce working crafts for the launch.
Over two days of attempts, Carmack's crew struggled with many difficulties. They made six flight attempts, two of which looked very successful. One of the other attempts lasted 83 seconds, even with a crack in its combustion chamber, a sign that the Armadillo Team is improving upon its designs.
On Saturday, the craft was poised to capture victory, but the multi-legged lander self-aborted and tipped over upon touching down. Then on Sunday came the worst disaster which doomed any future launch attempts. The craft was undergoing ignition and preparing to launch when a boom rocked the desert landscape and flames sprung up, engulfing the craft. The engine fire was very destructive to the craft and caused pieces to fall off and disconnected its cabling.
Peter Diamandis, Chairman and Chief Executive Officer of the X Prize Foundation, was quick to react with a pre-scripted response scenario. He elaborates, "From the field, we heard a little bit of a boom and there was a hard start on the engine of some type."
Pete Worden, one of the Lunar Lander Challenge judges and director of NASA's Ames Research Center, had consoling words for the Armadillo Aerospace team afterwards. "It's over for them for this X Prize Cup. I do think they are getting there...it's a robust design. I think they'll make it. Once again, it proves that rocket science is hard."
Carmack's team was not available for immediate comment, but they decided not to try for another nighttime attempt, on account of the massive damage. They will likely be back next year though with a refined design.
If Carmack's team eventually succeeds, they can set their aim to the Level 2 challenge. The Level 2 Challenge is far more difficult and requires the rocket to hover for twice as long before landing precisely on a simulated lunar surface, packed with craters and boulders to mimic actual lunar terrain. The hover times are calculated so that the Level 2 mission closely simulates the power needed to perform a real lunar mission.
The total prize for completing the Level 1 and Level 2 challenges is $1.35 million USD.
With that kind of motivation and a legend like Carmack at their helm Armadillo Aerospace seems poised to one day overcome their demons and win this challenge, despite this setback.

I had a project at work a few years ago that required high speed air flow to remove a build-up of metal shavings and oil from an automatic grinding machine(can you say "fire"?). I found that the application was going to require velocities in excess of mach 1 and started working on a nozzle to complete the project. The superintendent of the area wasn't happy with the slow progress I was making so he called me and my boss into his office and started to complain. I argued that it was a difficult project and it would take some time to complete. After a while the superintendent got fed up and screamed "C'mon guys! It's not rocket science!" To which my boss replied, "Umm, actually it is rocket science. In order to move air faster than the speed of sound you must use a well designed nozzle of the type used on most rockets." He left me alone to complete it on my timeline after that.

I should note that I was not attempting to be overly critical of the work of Aerospace Engineers, Engineering Physicists or other related fields. Working in the industry myself I have a lot of respect for those who tackle the complexities of what many consider 'Rocket Science'. The work can be very hard, but most reasonably intelligent people can perform 'Rocket Science' with enough dedication and perseverance to develop their technical skills and related knowledge based on experience.
I have nothing but respect for my fellow Engineers, especially since I ended up passing on the thermodynamics and instead develop military Aircraft avionics for a living. I just don't like it when the term Rocket Science is used as some sort of elite and unattainable status symbol or barrier.
People are capable of great things when they remain dedicated to the pursuit of knowledge.
