Float. Because there is no force or gravity to support them.

Presumably the most important force on an accelerating space shuttle is the force of the rocket engines (thrusters). Certainly other forces are present, including gravity and air friction.
The primary function of a space shuttle is to take notes on what happens in space. Countries from around the world use space shuttles to study details of other planet, moons, stars, and other objects in space.

Yes, it affects all objects in space (and all objects have a gravity of their own, that grows with size/"weight"). The reason why people talk about "zero gravity" in the space station and shuttle is because both the shuttle and the people inside it are affected by the same amount of gravity, so relatively they are falling at the same rate. Hence people inside the shuttle will not be moving towards the edge of the shuttle due to gravity. Take a football (the shuttle) and a tennis ball (some people) and hold them at the same distance from the ground and then release them (withuot adding any force, just let go). You will see that both objects will be affected by gravity, but relatively the tennis ball and the football are moving at the same speed. Now imagine that the tennis ball was inside the football and voilá, you have the shuttle scenario. Obviously the space shuttle is not falling directly towards the earth, it is actually "falling past it" - something that scientists call "orbit".
No Gravity.

UFO's: as of yet unidentified flying objects.

almost as much as the shuttle's weight on Earth's surface

Well they are used because without them the space shuttle would not be able to have enough force to escape the earths gravity when it was being launched.
it dosent, its very hard to get a space shuttle off the ground it uses thaousands of pounds of force to lift it.
