Plasma Rocket Occult

NASA spinoff firm the Ad Astra Rocket Company has announced a key milestone in ground testing of its prototype plasma drive technology, Variable Specific Impulse Magnetoplasma Rocket (VASIMR).

The VASIMR first stage jet fires up, 22 Oct 2008The electric rocket turns on.

The VASIMR “helicon first stage” – which generates the plasma for acceleration by the rest of the drive – has achieved its full rated power of 30 kilowatts using Argon propellant, according to the company. This paves the way for further trials in which in which the ion-cyclotron second stage will get to strut its stuff, boosting the helicon plasma stream to the target power of 200 kW.

The successful first-stage fire-up was a collaborative effort between Ad Astra and Nautel of Canada.

“We are elated with this achievement and exceptionally proud of the Ad Astra-Nautel team whose diligence and dedication made it possible, in spite of the disruption caused by the [recent] hurricane,” said Franklin Chang Díaz, Ad Astra’s chairman and CEO.

The idea of the plasma drives is to use electric power to blast reaction mass (in this case Argon) from its rocket nozzles at a much higher speed than regular chemical rockets can achieve. This means that the carrying spacecraft gets a lot more poke from a given amount of fuel, and so can make interplanetary journeys in much shorter times. Another potential application seen for VASIMR is maintaining the orbit of the international space station (ISS) without the need to burn large amounts of chemical rocket fuel.

VASIMR is the brainchild of Mr Chang-Díaz, MIT plasma physicist and former NASA astronaut with seven Shuttle flights and 1600 hours in space. Chang-Díaz nowadays develops VASIMR at the Ad Astra Rocket Company. He believes that VASIMR – or some kind of more fuel-efficient propulsion, anyway – must be developed, or travel beyond Earth orbit will never become a serious activity.

For now, Ad Astra is in negotiations to put a VASIMR test unit aboard the ISS, to help in maintaining station orbit and simultaneously prove the plasma drive tech in space. NASA seems unwilling to find room for VASIMR on any of the remaining planned Shuttle flights to the ISS, but there have been hints that it might travel on a commercial-off-the-shelf lift (for instance aboard a Falcon rocket from Elon Musk’s SpaceX venture) – if any of these actually come into service soon.

No surprise there, NASA has been nothing but a front for the Pentagon for fifty years.

But on the plus side, NASA and the military ( GE, Boeing, Lockhead-Martin, etc.) doesn’t seem interested in blocking anything Branson, Musk, Beson and the others are attempting to do.

I’m not sure if that’s a good or bad thing.
