Flight 7 of the Masten Space Systems reusable launch vehicle demonstrator XA-0.1B-750. Here it was programmed to fly a square pattern around the center, and then do 45 degree rotation and back using RCS before landing. The flight was 30 seconds long, here played at 1/10th speed. This is the first bipropellant RLV to fly with an aluminum rocket engine, the second flight of the day with that engine, and the 7th flight of this vehicle.
