Most of the movement, the orbiting of the shuttle around Earth, comes from the launch which gets the shuttle up to over 17,000 miles per hour. While in orbit, astronauts use the the shuttle's reaction control system to make adjustments to the shuttles orbit. The main engines are used again at the end of the mission to slow the shuttle down allowing the Earth's gravity to the rest of the work to bring the shuttle and astronauts back to the ground.
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 main difference is that a manned Mars mission is a great deal longer.
The first functional shuttle ever to be produced was the Columbia in the year 1981. This shuttle was designed and invented by NASA and not by any single person. Plans to invent the Space Shuttle began even before the Apollo Lunar Missions in the year 1969.The main concerns at that point were logistics; how much the shuttle would cost and how it was to be built. Hope this helps.
The three main parts of a space shuttle is the orbiter, the cone, and the wings.
The main mission of the space shuttle program was to provide transportation for both astronauts and supplies, to and from the international space station. There were several other missions as well.
Reusablility, longer missions, larger crew, and larger payloads.

Astronauts are in a continuous free fall the whole time they are in orbit. You may now ask though, why don't they hit the ground? They never hit the ground because they are traveling fast enough laterally that they miss the earth. In a sense, yes gravity does affect them, that's how they stay in orbit, but they do not feel the affects of it because they are always falling. If you were to sky dive or jump off of a high surface, you would experience the sensation of zero G, you just do not experience the no friction/ airless environment that they do. A quick factoid, when astronauts come home from shuttle missions, from being in the weightless environment for that amount of time, they actually loose some of their muscle mass, in some cases the loss is so great that some astronauts will not be able to walk away from the shuttle once it is back on earth. This is the main concern on future Mars Missions. Being out of earths influence of gravity for months on the trip to Mars can be fatal.
UUUHH...it's called a "space shuttle" main engine...why do you think?

The main advantage of the space shuttle is its ability to be re-used. This provides for quick turnarounds for launches.
There are 9 main story missions.
