The 2020 Mars Rover may be years away, but determining where it will land is already a hot topic among scientists and engineers. Many of the former gathered in early August for a site selection workshop. We talk with Co-Chair and Mars veteran Matt Golombek, JPL astrobiologist Lindsay Hays, and Ken Edgett of Malin Space Science Systems. Emily Lakdawalla tells us how Curiosity takes those beautiful selfies, and there’s another LightSail patch and Planetary Radio t-shirt to win in the What’s Up space trivia contest.
