To place a satellite at a height of 300 km, the launching velocity
should atleast be about 8.5 km s-1 or 30600 kmph. If this high velocity
is given to the rocket at the surface of the Earth, the rocket will be
burnt due to air friction. Moreover, such high velocities cannot be
developed by single rocket. Hence, multistage rockets are used.
To be placed in an orbit, a satellite must be raised to the desired
height and given the correct speed and direction by the launching rocket
At lift off, the rocket, with a manned or unmanned satellite on top,
is held down by clamps on the launching pad. Now the exhaust gases
built−up an upward thrust which exceeds the rocket's weight. The clamps
are then removed by remote control and the rocket accelerates upwards.
To penetrate the dense lower part of the atmosphere, initially the
rocket rises vertically and then tilted by a guidance system. The first stage
rocket, which may burn for about 2 minutes producing a speed of
3 km s-1, lifts the vehicle to a height of about 60 km and then separates
and falls back to the Earth.
The vehicle now goes to its orbital height, say 160 km, where it
moves horizontally for a moment. Then the second stage of the rocket
fires and increases the speed that is necessary for a circular orbit. By
firing small rockets with remote control system, the satellite is separated
from the second stage and made to revolve in its orbit.

^ length of a satellite 'launching vehicle' is roughly 300mts. Then how can a satellite be 77kms long?! Round figures : 5 x 5 mts
$51 million has been the average per-satellite launch cost between 1999 and 2009.

Actually, the US did not launch the first space satellite. The former USSR did, in 1957, launching Sputnik-I. The US followed in 1958 with Explorer 1, formally, Satellite 1958 Alpha. Dwight D. Eisenhower was president at that time.
it will take 1000 billion $ for launching a satellite in the space.
If the satellite stays on Earth, it would be quite useless.

Korea is not launching rockets at the US. North Korea just launched a satellite on a rocket into space.
