Design integration of aerocapture and aeromaneuver vehicles for a Mars sample return mission

The concept of using an aerocapture vehicle for Mars and other planetary missions is a technology that yields significant fuel savings. This concept uses the planet's atmosphere to dissipate excess velocity of the entry vehicle allowing it to go into orbit. A conceptual design integration study of two configurations of aerocapture vehicles which can make an aerodynamically controlled entry has been made. The first configuration contains the existing Viking type Lander and an Orbiter. The second spacecraft is more general in payload and could be used to place an Orbiter and a Lander on other planets with a single aeroshell.
