High program cost has been a major reason that Mars Sample Return missions have not yet occurred. A low cost Mars Sample Return mission is proposed that can be launched in the 2005/2007 timeframe. This mission concept minimizes the total energy required by avoiding capture of the Earth Return Vehicle, ERV, at Mars. Deep Space Rendezvous, DSR, with a Martian sample offers significant cost savings over Mars Orbital rendezvous. The ERV rendezvous with the sample sphere is significantly simpler than under orbital conditions. The ERV propulsion system can use a simple monoprop design. The ERV carries a Sample Return Capsule (SRC) and the design is derived from the spacecraft for the Stardust comet sample return Discovery Mission. Many of the other hardware elements are derived from previous MSR project and concept studies by JPL and LMA.
