The main goals of the AEROFAST project are, to design an AEROCAPTURE vehicle and to improve the AEROCAPTURE technology. An important step, to allow for human exploration of the solar system, is to develop advanced transportation systems to move humans and cargo between GEO and LEO, or to return them from the Moon of from Mars. Typically such a vehicle must rely on AEROCAPTURE to be mass efficient: using atmospheric drag to slow space vehicles is regarded as one of the largest contributors to making both lunar and Martian missions affordable. In the coming decades, AEROCAPTURE will become one of the core capabilities for efficient planetary transportation. This technology allows for a large amount of mass saving (up to 30%) at launch, and it is well adapted for large weight missions (Sample return missions and manned missions). For an insertion into a low Mars orbit with propulsion, 41% of the initial mass is put on final orbit whereas with an aerocapture manoeuvre 82% of the initial mass is put into final orbit. Today the technology readiness level, in Europe, of such an aerocapture mission is roughly 2 to 3. AEROFAST's goal is to prepare for a flight demonstration on a planet with an atmosphere (earth or even more attractively Mars) and to reach TRL 3 to 4 in the frame of this FP7 first call.
