From the mid-1990s until her death, Ride led two public-outreach programs for NASA—the ISS EarthKAM and GRAIL MoonKAM projects, in cooperation with NASA's Jet Propulsion Laboratory and UCSD. The programs allowed middle school students to request images of the Earth and the Moon. Ride bought a house in La Jolla, California, and O'Shaughnessy moved in after taking up a teaching position at San Diego Mesa College. She turned down offers from President Bill Clinton to become NASA Administrator, not wanting to leave California, but did agree to serve on the President's Committee of Advisors on Science and Technology (PCAST). This involved flying to Washington, D.C., every few months for studies and presentations. Due to the experience at CISAC, Clinton appointed her to a PCAST panel chaired by John Holdren to assess the risk of fissile materials being stolen in Russia and ending up in the hands of terrorists.
