NASA to Test Plasma Rocket at International Space Station
Posted by Adam Frucci at 12:30 AM on August 9, 2008
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]

Can we make the radio waves that propel the ship jam to Jimmy Hendrix? Spread the love across the universe while exploring.

Well, as long as they have a working warp core by 2063, it's all gravy, baby.

You had me at 'plasma rocket' and 'space', but then you went and added 'nozzles made of magnetic fields' and 'nuclear reactor'. I need to go change my pants.

Is he flowing because he was melted by the plasma?

They should strap a few of these to the international space station itself and put IT in lunar orbit. Use it as a stepping off point for lunar exploration/colonization.

I'm quite sure that involving properties of black holes will be absolutely safe. *Sarcasm*

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.

It took Apollo three days to get to Lunar orbit and this marvel of new technology will get a ship there in six months?

Hope there's a backup ion propulsion with that plasma too. Don't want to be stuck in space without some redundancy cuz it's going to be a while before rescue arrives. Personally, I'll wait till the warp engine gets back online and operational.

@velvetwoodstock: @Hiphopopotamus: I've actually read up a bit on plasma rockets/been talked to about them by someone working on them (VASIMR). It's not like they haven't already done test firings of the principle. I got to see the machine that they used for testing, though it was at the time running the pump to bring it back to a vacuum (the buggers only work in relative vacuums, or else things get explode-y pretty fast).
I've no idea how any of it relates to black holes, however...

@Log1c:
Last I read, is that plasma engines provide almost no thrust.... but since the can be lit and run constantly, speed builds up in space fairly quick due to the lack of drag.
Just think that if you were able to push 1 G for a year you could be nearly at the speed of light!

Too bad they didn't think about linking the black holes created by the LHC and the plasma engine. They could throw M&M's into space, from europe.

Too bad they didn't think far enough ahead to have the blank holes link and just throw stuff through the LHC black hole and have it show up in space.

Yes. On nothing but solar power. Re-usable up to 6 times. (which I take to mean it can make the round trip 6 times before the catalyst or whatever the radio waves react with is defunct.)
If they add a power source greater than just solar, like a reactor, they can do it in 39 days.

@tomholiday: Yep. It's slow because it's designed to be CHEAP. It's a tug boat.
I think the "black hole" reference is pure hyperbole: this uses plasma jets. Black holes can also create plasma jets. Of course, there are probably electrical discharges within materials falling into a black hole, so I guess a light bulb also uses black hole physics.

"follow the same principles that scientists believe govern black holes. "
I'm pretty sure that gravity governs black holes. Actually I'm pretty sure that gravity is the King God Emperor of black holes. Not sure how gravity govern plasma rockets?

people miss the point speed isnt everything ... fuel is the biggie... we cant go to MARS on f*cking rocketfuel, we'd need a tank the size of the moon to get their (sarcasm) ....
hence the idea currently for slower but more effective nearly limitless sources, such as this and the solar sail ideas....
also this is based off solar generation not a massive nuclear reactor that would get us their 100x faster using the same technology.
personall i dont care if it takes 6 months, as long as the first shipment back is 1 ton of HELIUM-3 to power the f*cking world... i mean jesus christ the moon has enough helium-3 to power the earth for well... forever probably yet, we havent gone their to get any, i mean we already know earth has barely hence why its not feasible as a clean, safe source of energy for the world, but hell if you can have 6 month regular shipments of the stuff from the moon of a ton or so then screw the big "energy crysis" just start prepping for helium3 usage and get the damn supply route ready to the moon!

Correct me if I'm wrong, but isn't plasma the liquid component of blood? If the rocket propels itself through plasma harvested during flight, isn't there the danger of overly anemic astronauts unable to complete their mission?

@phantam: There's some debate about the actual effectiveness of Helium-3 as a supposedly clean fusion fuel. I mean, it might work fine, but as with most things, it probably also wouldn't live up to the hype in any case- especially since it'll probably still produce a fair amount of neutron-soaked reactor shielding to dispose of, even if its not as much as some of the other processes. And even if you did get the fuel, you notice we're having a lot of trouble producing a sustained and stable fusion reaction, much less a reactor that even makes break-even.
Anyway, in regards to the plasma thrusters, I understand that high efficiency space thrusters are the key to making space economical for industrial and other civilian uses, but the 12 year old wannabe Space Ranger inside of me still finds it hard to get very excited about any space engine that wouldn't potentially allow me to cruise between the planets with 3 Gs of constant acceleration strapped to my ass.

What about ion rockets? Is ion propulsion more advanced and sophisticated then plasma rockets? All this talk about ion propulsion I thought that it would have been the next step for interstellar travel.

um what if this works too well. Shouldn't they not test it out on the INTERNATIONAL space station. I mean what if this thing blows the station out of orbit.

Wow! This is truly amazing to me. I'm glad to hear some good news like this.
I always wondered why we had nuclear power subs, but no nuclear power space ships. So its good to see were finally catching up in that sense.
I look forward to the second generation. Generation 1 sounds like it needs to be skipped. Actually G1 sounds like it would be beneficial in the long term.
