Why a multi stage rocket can reach escape velocity more easily than a single stage rocket?
The delta v required to reach low Earth orbit (or the required velocity of a sufficiently heavy suborbital payload) requires a wet to dry mass ratio larger than can realistically be achieved in a single rocket stage. The multistage rocket overcomes this limit by splitting the delta-v into fractions.
How fast do you have to go to reach orbital velocity?
This really depends on what you mean by “into space.” If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour.
Why are two stage rockets used to launch satellites?
For the projection of an artificial satellite, it is necessary for the satellite to have a certain velocity. Hence, a minimum two-stage rocket, one to raise the satellite to the desired height and another to provide the required horizontal velocity, is necessary for launching of a satellite.
Do all planets orbit at the same speed?
No. Orbital speed is determined by the mass of the object you are orbiting and your distance from it. All of the planets are orbiting the sun, so the mass is the same, but the distance is different. The further away they are, the slower they go.
Why are rockets staged?
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.
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.
