Heliocentric Velocity - an overview ScienceDirect Topics
WebThere are three primary results of the calculation of the heliocentric trajectory: The required spacecraft velocity at the edge of the initial planet’s sphere of influence, such that it is placed on the appropriate transfer trajectory. The spacecraft velocity at arrival to the final planet’s orbit around the Sun. The timing of the transfer ...
