rockets that carry satellites, robotic spacecraft
and manned spacecraft in to the space are known
as Launch vehicles or boosters.
Launch vehicle consists of three or four stages.
These stages are assembled on top of one another,
sometime a cluster of rockets called “Strap-On
Motors” encircle the first stage of a launch
After lifting off from the surface of the earth
a launch vehicle takes anywhere between ten to
thirty minutes to place a satellite / spacecraft
in its required orbit
