STENNIS SPACE CENTER, Miss. (AP) Triggering a massive cloud of vapor and a roar, officials on Monday test fired a rocket engine designed to be part of a reusable spacecraft that can launch into space repeatedly with a quick turnaround time. The AR-22 engine will power an experimental spacecraft called the Phantom Express that's a collaboration between the Defense Advanced Research Projects Agency, Boeing and Aerojet Rocketdyne. Engineers are currently testing the engine over a 10-day period by firing it up for 100 seconds and then doing it again 24 hours later. Monday's was the sixth of what is anticipated to be 10 test fires.
