Mars 2020 EVOLUTION OF A ROVER

摘要

This summer, the Mars Perseverance rover will set out to join Curiosity on the Red Planet. The two rovers, both built by JPL (which Caltech manages for NASA), share many design features but play different roles in the ongoing exploration of Mars and the search for ancient life. They also differ in important mission-specific ways: while Curiosity has identified and continues to study environments where ancient microbes could have lived, Perseverance will seek direct signs of ancient life and prepare geological samples that a future mission could bring back to Earth.
