The Mars Exploration Rover mission was declared complete on February 13, 2019.  On the very next day, MER Project Manager John Callas and Deputy Project Scientist Abigail Fraeman came to Planetary Society headquarters for an extended and emotional conversation with Mat Kaplan and Emily Lakdawalla. They talked about the beloved rovers and the women and men of the team that has guided them for so many years. What’s Up offers another opportunity to win a coveted rubber asteroid as we learn about the night sky and more.
