The Advanced Space Propulsion Laboratory (ASPL) is a new installation at the Lyndon B. Johnson Space Center, NASA. This new facility is investigating the application of magnetically vectored and RF heated plasmas to space propulsion. The central experimental device is a small versatile tandem mirror configured system. The total length of the device is 3.2 m, the central plasma radius is approximately 0.1 m, the mirror magnetic field is up to 2.0 T and the central cell field is up to 0.2 T. The experiment generates and heats the plasma using ECRH and ICRH. A 2 kW, 14 GHz klystron and a 200 kW, 1-10 MHz RF transmitter are being brought into operation. Methods for efficiently heating and preferentially exhausting the plasma out of a hybrid magnetic nozzle at one end of the mirror device are emphasized. The advantages of this novel concept are: electrodeless operation and variable thrust/specific impulse at constant power (200 - 30 N / 5000 - 30,000 seconds at 10 MW with 60thrust operation that is optimized for either minimum flight time or high payload. Examples of flights to Mars are presented where 90 day transit times can be accomplished.
