Aerobraking has been successfully used to lower the propulsive onV required toachieve a desired science orbit for a number of missions, but it requires significantresources for tracking, navigation, modeling and maneuver planning.NASA is now exploring the transition of the technology to a spacecraft environmentto enable autonomous aerobraking. This paper describes the modificationsto flight and testbed software from a prior interplanetary mission thatwere made to incorporate aerobraking and navigation algorithms. The flight architectureand algorithms are presented along with preliminary simulation resultsfor several typical orbits around Mars.
