NASA has approved the Mars Sample Return (MSR) initiative for advancement to Phase A, including planning to get the sample back from the Red Planet.

The Mars sample collection program is part of a larger, decade-long Mars project under which NASA and ESA seek to explore the Martian planet and check any traces of existence that could once occur on the planet. 

This, the agencies conclude, will bring us further to grasp the origins of existence on Earth itself. Rock samples were obtained from our neighboring world for this research and carried down to Earth.
