NASA to Test Plasma Rocket at International Space Station

Plasma rockets are the rockets of the future. They use the same stuff that makes up the sun and stars, and follow the same principles that scientists believe govern black holes. And now, NASA is ready to harness that energy for their own devices. They're planning to test a plasma rocket at the International Space Station.


So what, exactly, is a plasma rocket?

Rather than heating chemicals and directing the resulting gases through high-temperature metal nozzles, VASIMR uses radio waves to create and speed up free-flying, electrically charged particles known as plasma. The concoction is then herded through nozzles made of magnetic fields, not metals like traditional rocket engines.

Designed by a former astronaut who's flown in the shuttle seven times, the plasma rocket will use solar power to produce energy to convert into radio waves. This makes it reusable, and the plan is to have it haul things from low-Earth orbit to low-Lunar orbit, a trip that would take about six months to haul one ton of equipment, and it could be reused six or more times.

They hope to launch the engine up to space in 2011 or 2012. And while this engine isn't going to be suitable for transporting people, NASA is already thinking about the next generation of this design: one powered by a nuclear reactor, cutting the trip time down from nine months to 39 days. Awesome. [New Launches via Discovery News]


The Hadron Collider creates a worm-hole on Earth and then the Plasma Rocket creates a black-hole in space, causing a anti-matter field that will finally solve the universal problem of bad hair day. I can't wait.

This sounds like a great concept, but I admit that it reads more like a Star Trek TNG episode to me.
