After hurling through space for 7 months, NASA's Perseverance rover landed on the Martian surface less than a month ago. Now what? In this class, we will uncover why scientists believe that Mars potentially had life and how the rovers Perseverance and Curiosity help further the search for life by collecting and analyzing biosignatures. We will also delve into the implications of these missions in terms of future space exploration and our understanding of the world.
