NASA's Johnson Space Center Oral History Project lists Silver's involvement as follows:    Silver's work with the Apollo Program has been recounted in Andrew Chaikin's "A Man on the Moon" (1994). The book became a TV mini-series in 1998, with David Clennon portraying Professor Silver in the HBO docu-drama series "From The Earth To The Moon". In the series' Episode 10 "Galileo Was Right", Silver is shown teaching the Apollo 15 astronauts field geology, and participating from Houston's Mission Control in their lunar extra-vehicular activities (Moonwalks). Silver was interviewed about the episode and he felt that it "romanticized" the experience, and had minor historical inaccuracies, but otherwise liked it and showed it at a lecture in 1999. In 2002, Apollo 15 Commander Dave Scott devoted a section of his co-authored book "Two Sides of the Moon" to the training and instruction that Scott and other Apollo astronauts received from Silver. Silver is a board member of the Caswell Silver Foundation at the University of New Mexico. The Foundation was created in 1980 through an endowment by Caswell Silver, an alumnus of the Department of Geology, independent oilman, and Leon Silver's brother. The Foundation supports education and research at the Department of Earth and Planetary Sciences at the University of New Mexico. His grandnephew is statistician and journalist Nate Silver. For his significant scientific achievements in the development of highly precise isotopic compositions of uranium and lead in minerals and the applications of the age determination procedures in the analyses of lunar material. While diligently conducting these laboratory investigations of lunar material, he provided a major contribution by training the astronauts in geological sciences which, through his enthusiasm, leadership and guidance, has led to the successful exploration of the moon.
