Hohmann Transfer Approach: is a very common orbital maneuver used by astrophysicists to send a spacecraft from a small circular orbit to a larger one.
A Hohmann Transfer is a two-impulse elliptical transfer between two co-planar circular orbits. The transfer itself consists of an elliptical orbit with a perigee (nearest point to Earth) at the inner orbit and an apogee (farthest point from Earth) at the outer orbit. The fundamental assumption behind the Hohmann transfer, is that there is only one body which exerts a gravitational force on the body of interest, such as a spacecraft. This is a good model for transferring a craft from earth’s orbit to the orbit of mars.
