• New Plasma Rocket Can Shorten Mars Trip To 39 Days
    75 replies, posted
I think people are neglecting that this rocket type is still quite a ways out in development. This is a 201kW (Kilowatt, 201,000watts). They said a 10->20MW,(10,000,000w->20,000,000w) is what they need to get, in order to get to mars in 39 days. The 201kw model will help the ISS cut it's fuel cost by A LOT. But it's the beginning technology. Like how the 4004 was the beginning of the PC. This would be the 8080. What we need is something like the AMD Athlon XP 64 (First dual core 64bit CPU) in order to be getting somewhere in a second. There is many more years, and much more technology to be had in order to be successfully voyage into space.
[QUOTE=_Kent_;24013552]This is what I heard too, plasma rockets require nothing but one reactant gas and electricity to burn, so it can burn for a much longer time while carrying a much smaller mass of fuel. This allows it to reach much higher speeds.[/QUOTE] Yeah, as far as I know these engines are actually known for having a very low acceleration, so G forces aren't really a problem. Their advantage is that the extremely low fuel consumption means that unlike other rockets you can just keep it turned on all the way to the destination, which when you consider the absolute lack of friction in space, leads to extreme high velocities.

I know this is old news for some, but this is new for me. Bad ass, really is.
Don't rate me dumb if I'm completely wrong,but the speed would probably make astronauts going there look kinda like this: [img]http://dl.dropbox.com/u/7643056/12750835037071.png[/img] Except wearing a space suit and all.Well,they would look like that BUT MORE when still near Earth.
Speed doesn't do that, G forces do.

[QUOTE=smurfy;24012705]"Plasma rocket" sounds like something out of Star Trek.[/QUOTE] In startrek, they use a controlled matter antimatter reaction to produce energy, which is 93% efficient. This is less than 5% iirc. Thing is, we can't produce the amount of antimatter in super colliders to even begin a reaction, let alone make it cost effective to produce. However, this is still amazing none-the-less and my mind has been thoroughly blown.

I expected Badage Boys. I'm pleasantly surprised. It brings us THIS closer to being able to send equipment to the Gas Giants' moons to see if there really is life on there.

Am I the only curious as to how much this would shorten another trip to the Moon? [B]EDIT:[/B] Never mind, Wolfram Alpha figured that out :v: [url]http://www.wolframalpha.com/input/?i=earth+to+moon+at+21+km%2Fs[/url] Approximately 4 hours from the Earth to the Moon. That's a cross-country plane ride.

It'd take a year to get to pluto. Awesome.
It amuses me how ignorant people give an engine a top speed. Seriously folks, the speed reached depends on stuff like how heavy you are(thus how fast you can accelerate) and how long you can accelerate. Also you seem to be forgetting that in space we can't just hit the brakes and stop in a moment. We actually have to turn around and decelerate EXACTLY as long as we accelerated. ALSO, in space you just don't just fly in a straight line from point A to point B. You follow orbits etc.
Yeah but you could jump the gun and launch in a straight line and get to where the planet will be in the future instead of following the planet.

I just really hope that this is actually used, it seems that all of the cool aerospace stuff recently has fallen victim to budget cuts.
