When the White House proposed deep cuts to NASA’s Science Mission Directorate, we launched our most ambitious advocacy campaign ever. The House fully funded Planetary Science and Astrophysics. The Society’s advocacy work is funded by its members — your gifts pay for the staff, infrastructure, and credibility that made it possible. What was the specific mission or moment that first inspired you to join The Planetary Society? I was 19 when I received an invitation from Carl Sagan to join the Planetary Society in late 1980 or early 1981.
