This is an update for the Mars for Less mission. It includes a spacecraft3 configuration file for the biconic Earth Return Vehicle (ERV) which adds thruster flames and realistic aerodynamics. Also included is an alternative ERV that consists of a habitat and an Apollo type capsule to be used by the returning astronauts to descend to the surface of Earth. The aerodynamics of the capsule are based on some virtual wind tunnel work. It is modelled as a flying wing with numbers from a lift coefficient vs angle of attack curve included in the spacecraft3 configuration file. This gives quite realistic flight behaviour. Documentation is included describing the theoretical side of things.
