Velocity Requirements for Stopover Round Trips to Mars

Abstract

The velocity increments that are required to transfer a vehicle from an Earth parking orbit to a Mars parking orbit and return are presented for a range of departure dates during the time period from 1971 to 1977. The departure dates fall before and aer those for minimum-energy trajectories, i.e. , May 1971, July 1973, September 1975, and October 1977. The parking orbits are circular and are at an altitude of 100 n mi. The required velocity increments are presented primarily in graphic form. The individual and total velocity increments for one-way trips are given for transfer times ranging from 100 to 300 days, in 50-day increments.
