Plasma Exhaust From The VASIMR VX-200i, HD

This is one test firing in a series of experiments with the VASIMR VX-200 plasma rocket prototype. The rocket's 1st stage (a Helicon plasma source) was fired at 30 kW using a state-of-the-art solid state RF power supply, and the rocket's 2nd stage was fired at 109 kW using a second solid state RF power supply. Argon gas was used as the propellant, and gives a distinctive purple/blue/UV glow. The second half of the video is slowed down to 1/10 speed during the firing of the second stage.

The plasma diagnostics that can be seen in this video are situated on an x-y motion stage capable of moving side to side 200cm and in an out 500cm with 0.5mm precision. Because of the extreme temperatures and heating within the plasma exhaust, the diagnostics are all constructed out of refractory metals, high temperature ceramics, or graphite (or all three). The rocket and everything else seen in this video is located within a vacuum chamber, used to simulate the vacuum environment of space. Two cameras mounted within the vacuum chamber record a simultaneous top view and side of the VX-200 plasma exhaust.

The VX-200 is the precursor to the VF-200, a flight demonstration unit that is intended to fly on the International Space Station (ISS). http://www.nasa.gov/home/hqnews/2008/dec/HQ_08-332_VASMIR_engine.html

32 years in the making, trip to Mars 39 days according to Astronaut Chang-Diaz.

The only reason why i look forward to VASIMR is that a trip to the moon with it would be over in a matter of minutes/seconds (too lazy to count) AND a lot cheaper.

This would be a perfect opportunity to set up that moobase you always wanted, NASA.

Unlikely since the current plan is to use Argon as the fuel. Hydrogen is hard to keep liquid on long journeys.

Is the VF-200 going to be fueled with excess H2 from the ISS?
