  • AR-22 engine fired 10 times in as many days

    Jason RhianJuly 12th, 2018

    Boeing's Phantom Express had its AR-22 rocket engine put through its paces over the course of more than a week via tests to ensure the engine's ability to accomplish the space plane's objectives. It is hoped these tests will pave the way for the spacecraft to carry out missions to space with a pace similar to that aircraft currently carry out today.

  • Lucky 113: NASA tests RS-25 engine at highest-ever power level
