Scientific paper

Attention is given to the comparative merits of two options for the return to earth of Mars round-trip sampling probe missions. The first option makes use of an onboard propulsion system to place the returning vehicle into a highly elliptical orbit around the earth. An orbital transfer vehicle (OTV) or OTV/orbital maneuvering vehicle combination retrieves the sample from the return vehicle. The second option uses aerocapture to place the return vehicle in earth orbit; this maneuver imposes no greater weight penalty for proceeding to a low orbit than remaining at one that is high. The second option delivers the sample to a Space Station-compatible orbit for pickup.
