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.

Mars 2020 rover concept sketch
This artist's sketch is based on the Curiosity rover in NASA's Mars Science Laboratory mission, with proposed modifications based on the science definition team's recommendations. Mission planners would potentially leverage aspects of Curiosity rover design for a Mars mission designed to launch in 2020.

Send the probe down into Hellas Basin, a place where liquid water can exist under Martian temperatures and pressure.
