NASA's rover touched down on Mars this Thursday, February 18, after a seven-month trip through space and an even more terrifying seven-minute descent through the planet's atmosphere. Perseverance's primary goal is to search for evidence of alien life from a time when Mars resembled a young Earth - about 4 billion years ago. But the rover will also test new technology that could one day help Mars colonists terraform the planet's environment to our advantage.
