NASA-457M


NASA Cleveland electric/xenon rocket engine. Isp=2326s. 50 kW Hall thruster developed 2001-on.

In 2001, Aerojet Redmond Rocket Center was competitively selected to design a 50 kW Hall thruster as a complementary effort to NASA GRC's in-house development of the NASA-457M thruster. In FY04, following testing of the Aerojet design, the high-power Hall thruster development was refocused on the NASA-457M, 50 kW Hall thruster.

Electrical Input Power: 50.00 kW.

Specific impulse: 2,326 s.
First Launch: 2000-2004.
