Aerocapture is the technique of using planetary atmospheres to decelerate aspacecraft in a single pass to achieve nearly fuel-free orbit insertion.Aerocapture has been extensively studied since the 1980s but has never beenflown yet. The entry conditions encountered during aerocapture are stronglydestination dependent, and performance benefit offered by aerocapture is alsodestination dependent. Aerocapture is applicable to all atmosphere-bearingdestinations with the exception of Jupiter and Saturn, whose extreme entryconditions make aerocapture infeasible. A recent study by the NASA ScienceMission Directorate highlighted the need for baseline design referencemissions, as a starting point for system level architecture studies. Thepresent study uses the Aerocapture Mission Analysis Tool (AMAT) to compile alist of design reference missions at Venus, Earth, Mars, Titan, Uranus, andNeptune. These reference missions can provide an initial assessment of thefeasibility of aerocapture for a proposed mission, and provide intial baselinevalues for more detailed system studies. The reference mission set provides aquick estimate of the entry conditions, control requirements, and aero-thermalloads for architectural level studies.
