how fast would a ion propulsion spacecraft go?

Question

how fast would ion propulsion rocket be?
and how fast would you guess a fusion powered rocket be?

Answer 1

Speed is limited by the total momentum that can be imparted to the ions as they are expelled from the spacecraft. Figure out the mass of your spacecraft, the mass of ion material, and the velocity that the ions will be expelled. Then use conservation of momentum to figure out the rest. Of course, if you start to go a significant fraction of the speed of light, you will need to correct for relativistic effects.

Answer 2

An ion propulsion space craft is already traveling at something around 17,000 to 20,000 Miles Per Hour to
be out there in space and away from the Earth...Add to that the acceleration of the ion propulsion engine and you get what???

Depends upon how long the ion propulsion engine runs. The purpose of that kind of propulsion engine is to "add acceleration". So running it for one day might jack up velocity from 20,000 MPH to 20,050 MPH, run it another day and you might go to 20,100 MPH, etc., etc. Exact numbers will have to come to you from someone at NASA because these kinds of propulsion systems are not available off the shelf.

Speed of a fusion powered space craft is unknown because I don't think one has successfully made it off of the drawing board yet.

Answer 3

How long are you able to stay? What speed do you attain? A photograph voltaic sail could be ok out previous the orbit of Jupiter or according to probability Uranus, yet sometime after that the photograph voltaic wind does not have plenty tension and the sail could replace right into a criminal duty. the cost gained from an ion force relies upon on the thrust and the mass of the automobile being pushed, basically like all different rocket, (or railway locomotive for that count) and for the scale of time it operates. considering the fact which you have not offered those figures, the top result can't be calculated. however the superb speed stands out as the indispensable of acceleration over the years as calculated by Newton hundreds of years in the past.

Answer 4

The speed of any rocket is limited only by fuel and the time available for acceleration. As both of these require little fuel, if the voyage was long enough they could theoretically accelerate eventually to near the speed of light.

Answer 5

aliens know alot...they're using anti-gravity,advance propulsion and etc that can startled us...our minds are limited..:)

Answer 6

I don't know but ,I truly hope I am not standing anywhere close when it takes off.
