This paper considers joint optimization of trajectory and configuration in determining a minimum-mass vehicle for aeroassisted capture of a payload to a specific orbit at Mars. Aerocapture by a vehicle with a blunt aeroshell is assumed, supplemented by either chemical or nuclear thermal rocket impulses within the planet's sphere of influence. Optimal combinations of aeroshell size and exoatmospheric impulses are calculated for a range of entry velocities and constraints on integrated convective heating.
