MSR Lander Mission

The Mars Sample Return (MSR) concept is a campaign of three missions: a sample acquisition/caching rover mission, a lander mission to fetch the cache and deliver it to Mars orbit via a rocket, and an orbiter mission that would capture the orbiting sample (OS) container and deliver it to Earth via an Earth Entry Vehicle (EEV). A fourth component is the Mars Returned Sample Handling (MRSH) element that would include a sample receiving facility (SRF) and a curation facility.
