A Mars sample return mission (MSR) would be a spaceflight mission to collect rock and dust samples from Mars and to return them to Earth for analysis. One particular proposal, a joint project between NASA and ESA, would launch in 2018 with the sample return itself expected in the 2020-2022 time frame.
