Armadillo Aerospace's Tube Rocket undergoes its first test firing, and the concrete pad is just bursting with excitement. This is a longer burn at lower final pressure than the vehicle will see in a flight to altitude, but it was a good test of the systems, as well as a good heating test of the bottom of the rocket. The tube rocket, named Stig, is a LOX/alcohol reusable sounding rocket. It will test our high altitude systems and operations, and to carry payloads to the edge of space.
