I think the best name for the Mars 2020 rover is Examiner, here are three reasons why. The first reason is because when it collects the samples from Mars it examines them before being sent back to Earth.

The next reason is because it examines everything it sees and same goes for NASA'S new little helicopter.

The third reason is because it represents Earth by examining things from mars. Those things will be brought back to earth and to the science lab where scientists study the rocks and find out if there was life on mars.

The last reason is because when the rocks are brought back to earth and transferred to the science lab, scientists would examine them and find clues to an ending if there was life on Mars or, there would be.

In conclusion, scientists should examine to find out if there was life on Mars.
