A rocket or a launch vehicle is of 2 types: single stage and multi stage.
In single stage rocket, the fuel is contained in a single container. While in multi stage rocket, there are several containers placed above one another.
Such rockets keep dropping the fuel containers once they get emptied, reducing the overall weight and efforts needed to propel the rocket.
All the advanced rocket are normally multi-stage launch vehicle.
If you want to establish a satellite into the earth's orbit, the launch is orbital.
It tests the capacity of the rocket to see if it is capable - or still needs some improvement - of putting satellites into the orbit.
A sub-orbital launch is a bit like a mock test before the actual exam of an orbital launch.
As a result it doesn't reach out of the space and begin to return to the earth having attained a particular height in the space.
A sub-orbital rocket doesn't reach escape velocity.
A cryogenic engine provides more force with each kilogram of cryogenic propellant it uses compared to other propellants.
What is a Cryogenic Engine?
Cryogenic means low temperature. An engine that uses liquid fuel and oxidizer such as liquid oxygen and hydrogen stored at extremely low temperatures for combustion is called a Cryogenic Engine.
On the contrary, a regular jet engine burns its fuel (solid, liquid, or both) with the help of air sucked in from the atmosphere.
Cryogenic Engine Rocket - like GSLV - are a must to put heavy payload successfully into the earth's orbit.
Its way more efficient and powerful as compared to regular engine.
