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.
Astronauts' poop is sealed in bags on the International Space Station and stored until it is trashed in a spacecraft or cargo vehicle that burns up upon re-entry into Earth's atmosphere. Some missions have experimented with recycling waste into useful resources.
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.
because hydrogen is in the fuel cell. hydrogen is useful in many things including spacecrafts. please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true. I know for sure that hydrogen is used for rocket fuel because it is on the sheet. By Georgina thank you 4 going on wikianswers.com
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!!
Space Shuttles have people inside then but Sputnik don't The two have just about nothing in common....they were both launched by rockets - although very different ones. It would be useful to check out the links to the left to see the huge difference.
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.

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.
