How are Satellites sent into space?

Answer 1

In order to orbit the Earth, an object must have a velocity which will carry it around the Earth as gravity tries to pull it down. The speed required is called the "escape velocity" and is at least 25,000 mph (11.2 km/sec). Artificial satellites are placed atop large rockets which when fired provide the energy to accelerate the satellite into orbit.

Answer 2

Usually they're put in the nose of whopping great rockets, which then carry the satellites into space.

If a satellite is launched at at least 17,000 mph to obtain orbit, any lower than this and it will fall straight back down to earth. if it is launched over/at 25,000 mph it will fly into space and drift off forever! Getting a satellite into space requires that it be lifted up there. But that's not all. Lift a rock up a thousand feet and drop it. It falls to earth. Lift it up five miles and drop it. It falls to earth. Lift it up a couple of hundred miles (into space) and let it go. It will fall back to earth. Surprised? Don't be. We need lift, but we need to accelerate the satellite in a direction perpendicular to the force of gravity to put it into orbit (to achieve orbital insertion). Stand on the north pole and the earth turns below you. It's like standing in the middle of a merry go round. If we launch from the north pole, we have to put in all that lateral energy. If we launch from some place closer to the equator (the closer, the better) we gain the benefit of the velocity we have because we are further from the axis of rotation of the earth (remember the merry go round). That means less energy is needed to place a given payload in a given orbit.

Answer 3

a micanical arm
There are two options. The shuttle can place a sat into space with its 50' manipulator are, or the sat can be ejected out of the cargo bay on its own.

Answer 4

Using multi-stage rockets.
