The space shuttle is different from all other space crafts ever built because it is the only vehicle that NASA has to fly astronauts to orbit and back that can be used again. The space shuttle is almost 100 percent reusable. the only part that needs replacing is the large external tank. After every flight a new one needs to be made.
Manned spacecraft are very useful because it is easier to see and do things first hand than relying on only readouts from machines and senors.
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
Robots are very limited, very inflexible. They are only useful for dealing with the known; they cannot improvise. The Apollo astronauts returned over 840 pounds of moon rock. It would have taken hundreds or even thousands of robot missions to do as much.
they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells Because fuel cells do actually fart it's well documented. And they do a poo when they get tired! < SOOO TRUE!!
NASA or whichever company it is send a shuttle out into space and the have a little device on it that snaps photos of objects it passes by. Example: a shuttle launched from earth could take photos of the weather so people can study the patterns. Or the shuttle can take photos of the surface of a different planet so we can learn about the planet's surface.
They supply power to the spacecraft during missions.
The space shuttle is useful because it was the first reusable spacecraft. It is also capable of carrying satellites and other items into space. It is capable of repairing damaged items in space as well.
it lifts up the spacecraft
Without fuel, the spacecraft cannot launch.
Manned spacecraft are very useful because it is easier to see and do things first hand than relying on only readouts from machines and senors.
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
Because they do a lot of the missions that others can't do.

corn, fruit vegetables, anything that was useful to eat.
Whenever you were trying to reach high speeds or conduct exact experiments where friction would slow something down or cause heat. For example, friction is extreamly "unuseful" when spaceshuttles are re-entering the atmosphere because the friction of the spacecraft and the air create incredibly height temperatures. Special heat plates were invented to absorb this heat. If they fail, like in the re-entry of the Columbia Space Shuttle, the shuttle will be completely destroyed.
