Now NASA has a concept for Mars that I am in was hoping China will be using on the moon. There I was hoping Chang'e 5 will have a rover and it will bring samples back to the base to be transported back to earth. In fact I was hoping the rover could be a Chang'e 4 mission where the samples could be collected and Chang'e 5 mission could bring back.

NASA has pivoted on a key design point for the Mars 2020 rover, the first of several missions required to return a martian surface sample to Earth.

Once thought of as a sample-caching mission, NASA now plans for Mars 2020 to extract several surface samples from each region it visits and leave them on the ground for a future rover to cache, Ken Farley, Mars 2020 project scientist at NASA’s Jet Propulsion Laboratory, told the Mars Exploration Program Analysis Group (MEPAG) during a Feb. 24 meeting in Pasadena, California.
