space craft of a launching pad
As far as we know, it didn't. But if you can launch something harmless into orbit, you can also launch something dangerous into orbit, which was a big part of the fear caused by the Sputnik launch.
sure. there no problem int when it launch
satellite =)
It has to get up to 7km a second to get out of earth's orbit, then it orbits around earth.
Explorer 1 was in orbit for 111 days after launch on January 2 1958. I make that to be May 4, 1958.
To date rockets are the only method that can be used to put something or someone into orbit.
A nation that can launch something into orbit is a nation that can drop anything from orbit onto any other part of the world. Unless you trust the nation with orbital capacity, this can be a scary thought.
[Current cost to launch material just into earth orbit: about $10,000 per pound.]

We have sent probes from Earth to orbit Jupiter, and to fly by, but nothing has landed there.
Launch him high enough so that he goes out of the earth's orbit.
1957
Normally satellites are placed on top of rockets and carried into space, then they are released/pushed out of the rocket once it reaches space. It is first pushed out (injected) into an orbit close to earth called a "transfer orbit," meaning an orbit used to move it from the release location to the primary/intended orbit. Sometimes a booster motor is used to move it into the transfer orbit. After the transfer orbit moves it to the correct location another motor changes it's direction/motion into the final/primary orbit. Sometimes a satellite is carried into space by the Space Shuttle, and then released. After that it moves into a transfer orbit that carries it to the final orbit like other satellites.
