Description
NASA has used aerobraking to reduce the fuel required to deliver an orbiter in its desired final orbit around a target planet or moon that has a significant atmosphere. IT does that by replacing part of the fuel that would be required to provide the desired orbit propulsively with aerodynamic drag, by having the spacecraft fly through the upper atmosphere of the target multiple times. By using the multiple pass approach, the dynamic pressure and thermal loads will remain within the nominal spacecraft design parameters. Aerobraking has been used four times by NASA, once at venus and 3 times at mars. While aerobraking reduces the required fuel required to reach the final orbit, IT does IT at the expense of time (typically 3-6 months), continuous deep space network (DSN) coverage, and a large ground staff. The DSN and staff are required to design the maneuvers that the spacecraft executes during aerobraking that both keeps the spacecraft safe and will provide the desired final orbit. The combination of long time, staff and continuous DSN coverage results in aerobraking being a very expensive operational phase of the mission. As aerobraking has evolved, the operations have matured to the point that much of the daily operations could be moved to the spacecraft, thus saving much of the cost required for the aerobraking phase. The objectives of the nesc autonomous aerobraking assessment are to develop the algorithms required for autonomous aerobraking; develop a high fidelity flight simulation that will be used to demonstrate the feasibility of autonomous aerobraking; and, use this simulation to establish the feasibility of autonomous aerobraking, and determine the potential for the reduction in DSN coverage, and staff that autonomous aerobraking could provide. The purpose of this task order is to conduct phase 2 of the autonomouns areobraking research of which phase 1
