Question

how can we launch satellites into the orbit

Answer 1

All satellites today get into orbit by riding on a rocket. Many used to hitch a ride in the cargo bay of the space shuttle. Several countries and businesses have rocket launch capabilities, and satellites as large as several tons make it into orbit regularly and safely.

Answer 2

placing a satelite into orbit require a enormous amout of energy. the launch process are divided into two phases...
1.the launch phases
2.the orbit injection phases..

1.the launch phases
during the launch phase the launch vehicle places the satellite and transfer into orbit..an elliptical orbit have farthest point from the earth
2.the orbit injection phases
the energy require to move the satellite. from the elliptical transfer orbit into geosynchronous orbit is supplied by the satellite apogee kick motor thos is know as orbit injection phase
