Buzz Aldrin "First on the Moon: The Untold Story", Aldrin told an interviewer that they saw an unidentified flying object. He told David Morrison, a NASA Astrobiology Institute senior scientist, in 2006 that the documentary makers omitted the crew's conclusion that they probably saw one of the four detached spacecraft adapter panels. Their S-IVB upper stage was away, but the four panels had been jettisoned before the separation maneuver so they would closely follow the Apollo 11 spacecraft until the first mid-course correction. When Aldrin appeared on "The Howard Stern Show" on August 15, 2007, Stern asked him about the supposed UFO
Space rendezvous maneuvering thrusters to adjust its orbit to match that of its twin. The initial separation distances were in the range of , and slowly diverged to thousands of kilometers (over a thousand miles) over the course of the missions. In 1963 Buzz Aldrin submitted his doctoral thesis titled, " Line-Of-Sight Guidance Techniques For Manned Orbital Rendezvous." As a NASA astronaut, Aldrin worked to "translate complex orbital mechanics into relatively simple flight plans for my colleagues." The first attempt at rendezvous was made on June 3, 1965, when US astronaut Jim McDivitt tried to maneuver his Gemini 4 craft to meet
