I think the 2020 Mars Rover should be named Perspective. As with previous rovers, the name should have to do with giving humanity something new. The Opportunity rover gave us the first opportunity to explore Mars, while Curiosity represented the curiosity of the human race about exploring beyond our home planet. Naming the 2020 rover Perspective would continue this pattern, giving us a new perspective on possible signs of life on Mars. In the 2020 mission, one of the main goals is to look back at ancient Mars, and what it might have been like, while another is to look at the future of the planet, and what we might be able to do there. The name Perspective exemplifies this act of looking far through time in both directions, giving us new perspectives on the Red Planet.
