LaJolla's (now U.C. San Diego) Harold C. Urey. Other members of the panel who appear in the film are Gerard de Vaucouleurs and Nicholas Christofilos. The panel was assembled prior to the start of the Ranger Missions, so likely early 1960 or 1961. The Ranger program was a series of unmanned space missions by the United States in the 1960s whose objective was to obtain the first close-up images of the surface of the Moon. The Ranger spacecraft were designed to collide with the lunar surface, returning imagery until they were destroyed upon impact. Robert Jastrow (September 7, 1925 – February 8, 2008) was an American astronomer and planetary physicist. He was a NASA scientist, populist author and futurist. Thomas Gold (also known as Tommy Gold), born on May 22, 1920, died on June 22, 2004 was an Austrian-born astrophysicist, a professor of astronomy at Cornell University, a member of the U.S. National Academy of Sciences, and a Fellow of the Royal Society (London). Gold was one of three young Cambridge scientists who in 1948 proposed the now mostly abandoned "steady state" hypothesis of the universe. Gold's work crossed academic and scientific boundaries, into biophysics, astronomy, aerospace engineering, and geophysics. Gérard Henri de Vaucouleurs (25 April 1918 – 7 October 1995) was a French astronomer. Nicholas Constantine Christofilos (Greek: Νικόλαος Χριστοφίλου; December 16, 1916 – September 24, 1972) was a Greek physicist. The Christofilos effect, a type of electromagnetic shielding, is named after him. Harold Clayton Urey (April 29, 1893 – January 5, 1981) was an American physical chemist whose pioneering work on isotopes earned him the Nobel Prize in Chemistry in 1934 for the discovery of deuterium. He played a significant role in the development of the atom bomb, as well as contributing to theories on the development of organic life from non-living matter.
