WEBSTER, Texas (Ad Astra Rocket Co. PR) — Ad  Astra Rocket Company’s VASIMR® VX-200SS  Plasma Rocket has completed 88 hours of  continuous operation at 80 kW at the company’s  Texas laboratory near Houston. In doing so, the  company establishes a new high-power world endurance record in electric propulsion. The test  also demonstrates the maturity of the VASIMR® engine technology as a competitive option for  high-power in-space electric propulsion with  either solar or nuclear electric power. Electric  rockets operating above 50 kW/thruster are  considered “high-power.” 

WEBSTER, Texas USA and HALIFAX, NS, Canada – A new generation radio-frequency (RF) Power Processing Unit (PPU) for the VASIMR engine, built by Aethera Technologies Ltd. of Canada, has completed a series of full power acceptance tests at Ad Astra Rocket Company’s Texas facility near Houston. The unit completed these tests on August 12 by operating in a thermal steady-state with no anomalies at its full power rating of 120 kW.

The RF PPU is now ready to be incorporated into Ad Astra’s vacuum facility so that it can be tested with the VX- 200SS VASIMR prototype. These tests are part of Ad Astra’s ongoing program under the NASA NextSTEP partnership contract.
