Sally Ride changed the world. We are very sorry to hear of her recent death after a nearly two-year battle with cancer. Dr. Ride was an excellent astronaut, a remarkable educator, and a longtime Planetary Society friend and adviser. Her particular passion was to get girls excited about science. She did just that. Her Sally Ride Science programs, which include camps, academies, educator institutes, and festivals will carry her legacy into the future. I encourage everyone to take a moment over the next few days and honor Sally Ride by giving a young person a reminder that she or he could pursue a career in science and change the world just as Sally did. She will be missed.
