ROCKET OF DOOM
Armadillo Aerospace, led by videogame programming whiz John Carmack, plans to launch a manned suborbital rocket by the end of next year. Unfortunately for us, Carmack left his spaceship-in-progress back home in the shop. He did, however, show an early Armadillo design for a stainless-steel, hydrogen-peroxide-powered rocket engine [left]. In addition, he brought his aluminum, liquid-oxygen-and-ethanol engine that will power the suborbital ship [right]. Armadillo welder James Bauer [center] holds the engine design used by the small-scale Armadillo rocket flown at the X Prize Cup.
