If little or no resistance then yes, speed is the cae.
Ahhh....nm....so engines get a probe going, and the ion thruster makes it faster or for bad situations (ex: 1000 mile wide asteroid coming at probe).....Key word is "thruster"....(sighhh)
So if there's no interference in the gravity or air (like space), then it goes very fast?
Neither actually. I just love all kinds of nuclear reactor :)
i think this save was probably either inspired by the kerbal space program, or mars direct...
i would not like to be Mark Watney...
RTG's and ion thrusters.... who else here has read 'the martian' (for the noobs who answer no, it is NOT a book about little green men, or any aliens at all)
Ion thrusters are often used to manouver space probes and satelites. They us quite a lot of power, for very little thrust. However, they run entirely on electricity and ionisable gas, eg argon. Argon is a noble gas, hence nble (noble) can be ionised in game. Ion thrusters do have a very fast final speed, so say, a space probe is going to mars. The ion thruster won't be able to get it out of earth's orbit, but when it is, it will slowly accelerated up to possible a couple of thousand miles an hour, or faster. Most ion thrusters use either electromagnetic or electrostatic forces to push the ion (normally plasma) out the back. They were (I think) first thought up in he 1920s. Some modern designs use the hall effect, which means they don't need electromagnets for propulsion (I think).
Not to sound dumb but what is and ion thruster exactly?
