Is single-stage-to-orbit possible?

A single-stage-to-orbit (or SSTO) vehicle reaches orbit from the surface of a body using only propellants and fluids and without expending tanks, engines, or other major hardware. It is considered to be marginally possible to launch a single-stage-to-orbit chemically-fueled spacecraft from Earth.

What does a rocket need to be successful?

Attaining space flight speeds requires the rocket engine to achieve the greatest action force possible in the shortest time. In other words, the engine must burn a large mass of fuel and push the resulting gas out of the engine as rapidly as possible.

How does a rocket achieve orbit?

To get rockets into orbit, they need much more thrust than the amount that will get them up to the required altitude. At this speed, an object at that height will stay in orbit around the Earth. If speed is less than this, an object will fall back to the Earth.

What is single stage rocket?

A single stage rocket uses a single rocket motor or a cluster of motors to lift its payload to the desired altitude, and most low altitude sounding rockets are of the single stage type.

Why single stage rocket is not used for the projection of satellite?

This velocity is determined by no altitude of the satellite. Hence, a minimum two-stage rocket is necessary to launch a satellite into an orbit around the Earth. Therefore, a single-stage rocket is of no use.

Why is rocket staging important?

Because the amount of fuel it takes to launch a rocket is so high, modern rockets use a staging system. Once a stage has emptied out all its fuel, it detaches and returns to Earth so that the second stage can keep going without having to drag along the extra weight of the empty fuel tanks.

Why do we need multistage rocket?

We use a multi-stage rocket for launching a satellite to reach the desired height and gain velocity for the rocket. This helps in attaining a desired direction and increase in height and velocity. When the fuel for this stage is burnt completely the last stage gives the desired height and velocity to the rocket.
