Detail design of Mars transfer orbit
Abstract
An overview of interplanetary transfer orbit simulations and orbit injections is presented. The process for setting initial values (injection date and orbit elements at the orbit injection) was developed from the values obtained by the conceptual study. The following design concerns are considered: the velocity vector at injection; a transfer orbit that neglects the earth's gravity; the velocity vector upon reaching Mars--neglecting Mars's gravity; velocity increments necessary at perigee and apogee; and and flight time. Necessary speed increments and the Mars true anomaly at the transfer orbit injection were used to determine the transfer orbit injection date.
