NASA and Ad Astra team up to test VASIMR plasma rocket in space
Plasma propulsion may very well be our ticket to visit those little green men on Mars, which is why NASA is becoming besties with Ad Astra, makers of the VASIMR VX-200 plasma rocket. After successful terrestrial testing, the next step is to try out a VF-200 flight model in space -- and a new agreement gives NASA engineers access to VASIMR while letting Ad Astra leverage NASA's spacecraft expertise to get it into orbit. The plasma rocket was assumed to be destined for use on the International Space Station because it requires far less fuel than conventional boosters -- making it better suited than the propellant-hungry thrusters keeping the station in orbit today -- and can take advantage of the ISS's considerable electrical power (250kW) to fully test VASIMR's 200kW output. Plasma rockets produce sustained thrust, as opposed to the quick bursts of its chemical cousin, which makes it the preferred means of propulsion for space travel as well. NASA hasn't fully committed to either use -- but if Marvin and his fellow Red Planet denizens know what's good for them, they'll be watching VASIMR's development with great interest.
NASA might bring plasma rocket to ISS for testing
Ad Astra's VASIMR plasma rocket is about ready for testing, only problem is it requires the vacuum of space to do it in. NASA is now considering taking the rocket up to the International Space Station, clipping it on and firing her up -- perhaps even using it to reposition the station. Formerly of NASA, Franklin Chang Diaz left to form Ad Astra and perfect his plasma rocket, which he hopes will be able to take space vehicles from low-earth orbit to the moon. The rocket draws its own power from solar cells, and then uses radio waves to heat argon into plasma, and directs that plasma using magnets. Pretty fancy stuff, and since the rocket is reusable and can propel payloads double the size of equivalent chemical engines, there could be cost savings in the long run. Right now it seems the main hang ups for NASA are where to attach the rocket to the ISS where it won't be interfered with, and how to get it into space after the space shuttle is retired in 2010[Via Newlaunches.com]
