Question

why rockets are launched in space??

Answer 1

Spacecraft delivered into orbital trajectories become artificial satellites, which are used for many commercial purposes. Indeed, rockets remain the only way to launch spacecraft into orbit and beyond. They are also used to rapidly accelerate spacecraft when they change orbits or de-orbit for landing.

Sriharikota is ideal for eastward launches. SHAR's location on the east coast ensures that it gains an additional velocity of 0.4 km/s due to Earth's rotation to easily launch rockets. Most satellites are launched eastward.
