After trying to develop our 'Dual-Pulse" motor for a number of years we are taking a more conventional route with a 2-stage vehicle.
We have successfully fired our prototype sustainer and yesterday successfully fired for the second time our booster motor. We had help with mounting the motor on the static test stand by friends from both SpaceX and XCOR...what a bunch of great guys to work with. We will do one additional static test and if successful the motor will be then be flown for the first time.
