System Engineer Space OPS
Why does a spacecraft transferring from an initial circular orbit to a larger circular orbit perform two maneuvers, both of which increase it's speed, but end up with a slower orbital velocity in the final orbit than it started with in the original orbit?
The Hohmann Transfer, which is an orbital maneuver, focuses on the way a spacecraft or satellite transfers from one circular orbit to another circular orbit where the orbits are of different radii. When a spacecraft moves from went a low orbit to a higher orbit, the craft needs to accelerate. When the velocity of the lower circular orbit is higher than velocity of the higher circular orbit, where there is acceleration then the craft moves up in the slower orbit (Sellers& Astore, 2007). In other words, at the lower orbit the forward velocity is higher than at a higher orbit. The instantaneous velocity changes (ΔVs) are tangent to the initial and final orbits (Sellers, & Astore, 2007).
