spaceship facts?

Question

does anyone have facts about spaceships

Answer 1

There are a variety of spaceship designs and propulsion systems. Chemical rockets are used to boost space ships out beyond earth's gravity because combustion rockets combine safety with the greatest thrust. Nuclear powered rockets are considered to be a bit more dangerous.

Once in space, one defect of chemical rockets is that fuel tends to be exhausted quickly. An ion drive provides very little thrust, but you can turn the engine on and let it run for years with a small fuel mass. The acceleration is small, but it adds up over time.

Another spacecraft drive would be solar sails. The first ship launched to use a solar sail--the sail did not properly deploy, and that ship failed. Solar sails work by capturing light pressure and the solar wind--energetic particles streaming from the sun.

One nuclear powered design would be the detonation of a series of low yield fission devices to provide impulse thrust. Fallout is a "dirty" byproduct of this design.

Another design would be to mount rail guns or particle accelerators along the sides or central axis of a ship, and fire matter backwards. For every action there is an opposite and equal reaction--Isaac Newton. The drawback for this design is again the exhaust. Molecules (chemical exhaust) travelling at high speed do not pose a significant risk, but heavier masses might.

To boost an object (payload) to orbit from earth's surface, most of a spaceship's mass is fuel.

Answer 2

They suck, and likely will not get you to mars any time soon because you would be dead from radiation by the time you got there. Not to mention micro meteorite bombardment eventually ripping open the coca cola can.

Those are some space ship facts.

The source is about the NASA space shuttle.
