Armadillo Areospace

With all the political attention that Spaceport America has received following the resignation of the executive director of the New Mexico Spaceport Authority, Rick Homans, I felt it was necessary to shed some light on one of the lesser known companies that plans on using the facility when it becomes operational this year, Armadillo Aerospace.



Armadillo is headed by a rich geek with a dream (much like other private space companies that are popping up) named John Carmack, who developed notable video games like Doom, Wolfenstein, and Quake. Using his money and his enthusiasm for rocketry, Cormack founded Armadillo Aerospace as sort of an ultra science fair winning powerhouse. Using low cost, rapid build rockets, his group of engineers and enthusiasts have done well in several X-Prize competitions as well as the NASA Lunar Lander Competition. With these successes, Armadillo has set it's sights on suborbital space tourism and eventually orbital space travel.



What makes this company exciting is their ability to think outside the box when it comes to developing unique rockets. They have experimented with a variety of cheap fuels that dramatically lower the cost of lift off, and have demonstrated vertical ascent and descent. This fall, they will launch their Super-Mod vehicle to an altitude of nine miles, and bring it back vertically. This winter, they will aim for a 25 mile ascent.

It can be agreed on that the one major factor that is limiting space exploration is the high cost of breaking from from Low Earth Orbit. With this relatively low cost system, it will be interesting to see how this company helps pave the road for the next Renaissance into space.

Particles Found Inside Hayabusa

Last week Japanese scientists unloaded the sample return probe Hayabusa and were delighted to find particles within the spaceship. These could be the remnants of a deep space mission to the asteroid Itokawa that were scooped up several years ago. The Japanese are being very careful to not jump the gun on announcing the material is indeed from an interplanetary origin. They will announce in a few months if it indeed space dust from the asteroid or Earth material from Hayabusa's violent impact when they know for sure.

Asteroid seeking probe encounters system failure- not Hayabusa


Recently a probe was launched to explore a distant asteroid. Along the way it encountered system failures which could possibly disrupt it's course. Sound like the JAXA Hayabusa mission to you? Actually this is what is currently happening to NASA's Dawn probe. The probe was launched in 2007 and is heading for the asteroids Vesta and Ceres. The problem has to deal with part of its attitude control system shutting down unexpectedly. NASA scientists do not believe that this problem will affect the outcome of the mission.

Oh science jokes

James Breitmeyer, Yiannis Karavas, and Brigitte Berman during their training for recording the reentry of Hayabusa.

A science teacher from Massachusettes gave his class a problem 6months ago about a hypothetical space object penetrating the atmosphere. Turns out, the problem was real all along, and he and three of his students got to ride along on the NASA DC-8 that filmed the Hayabusa's return to Earth. Best teacher ever!

Hayabusa relatively unharmed


The Hayabusa spacecraft which crash landed into the Australian outback this past week after a seven year mission to the asteroid Itokawa looks to be in pretty good shape. Great job!
