ion powered space craft?

Answer 1

there is no question here

Answer 2

Yes, there is. Boeing makes two versions of ion propulsion thrusters: The Boeing 601HP and the Boeing 702. The Boeing 702 is the larger model.

Technically, both models still use matter as fuel - they both use xenon gas. They use an electrically powered ionization chamber to accelerate the xenon ions to incredibly high speed. Electrons are also ejected separately, but have such a small mass, they add little to the thrust. The primary reason for ejecting the electrons are so the xenon ions aren't attracted back toward the spacecraft.

All propulsion works on the principle of conservation of momentum. Momentum is equal to mass times velocity. If you eject mass out the back of the thruster at a certain velocity, the spacecraft will move the opposite direction (usually at a much slower speed, since the mass of the spacecraft is much larger than the matter ejected out the back of the thruster). If you can increase the speed that matter is ejected from the thruster, it reduces the amount of mass the matter has to have. That reduces the mass of the fuel, making the spacecraft much cheaper to launch.

Of course, since the ionization chamber takes a lot of electrical power, the reduced mass of the fuel is somewhat offset by needing larger solar array panels to supply the electrical power. Fortunately, solar arrays generally have a large area to mass ratio, making the trade pay off.

The other trade off is that XIPS thrusters (Xenon Ion Propulsion System) don't provide very powerful thrusts. Instead of firing in short, powerful bursts like normal thrusters, the thruster is virtually always 'firing' (a little like the difference between the tortoise and the hare).

The satellites used for XM radio use XIPS thrusters. A few other examples of satellites using XIPS thrusters are Europe's New Skies communication satellites, and the Galaxy XI communication satellite. There's several other programs that plan to use XIPS thrusters, with most being geostationary communication satellites.

Answer 3

Deep Space 1(DS1) had a Ion Propulsion System.It was launched aboard a Delta II rocket from Cape Canaveral Air Station,FL on October 24,1998.

Answer 4

what do you want to know?
yes there is such a thing, however few space missions have ever used it.
mostly because ion thrust provides a very low level thrust, usefull for long term missions, but nothing that requires high levels of thrust for short amounts of time.
here is the NASA FAQ for ion propulsion

Answer 5

there is such thing and there solar power,and hydrogen power
