Virtually all types of spacecraft and launch vehicles are made of aluminum or titanium alloy and a fiberglass/composite material.
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.
The fuel used by the Apollo 15 spacecraft as well as all the Apollo spacecrafts , was a mixture of oxygen and nitrogen gases.
Aircraft are driven by air breathing engines whether combustion or jet. All spacecraft must be propelled by rocket or something else that needs no air to perform
Spacecraft use either liquid or solid fuel. All rockets operate on a combination of a fuel and an oxidizer to help the fuel burn. Russian rockets use liquid fuel, a combination of Liquid Oxygen (also called LOX) and a highly refined form of kerosene (also called RP-1). American and other rockets and spacecraft use a combination of liquid fuel as above and solid fuel. Solid rocket fuel is composed of fuel like charcoal, metals such as alumnium or zinc, or even sugar along with potassium nitrate as an oxidizer all combined in a binder such as rubber or forms of plastics. An additive such as sulfur can also be added to help stabilize the burn. Once in orbit, hypergolic fuels are used. 2 chemicals are used which, when combined explode. This allows rockets to be used without any ignition source.
NASA's Apollo and Space Shuttle spacecraft all launched from Cape Canaveral, Florida.

All spacecraft for NASA's Mercury program were designed and built by McDonnell Aircraft of St. Louis, Missouri, using over 600 subcontractors and numerous design modifications from NASA scientists and the NASA astronauts themselves.

The Voyager probe/spacecraft lauched in 1977,has gone beyond our solar system and is headed for the next closest one although most NASA scientists believe even if it arrives there undamaged it will not have enough power to transmit back to Earth to confirm its location/existance.
The program was named after the Greek god of light, music, and the sun by NASA manager Abe Silverstein, who later said that "I was naming the spacecraft like I'd name my baby."
The Space Shuttle. It is almost all reusable except for the huge red fuel tank that pushes it up off the ground
Several advantages; mainly:A human needs food, air, and protection. An unmanned craft needs none of these; its use of energy and other "extras" is much less than for a human.An unmanned craft can be sacrificed; there is no moral obligation to return it safely to Earth.In summary, all this makes an unmanned spacecraft much cheaper than a manned spacecraft.

No spacecraft has visited all the planets.
