22 May 1969, 21:30:43 UTC: Just over 100 hours after launch from Kennedy Space Center, Snoopy, the Lunar Module for the Apollo 10 mission came within 47,400 feet (14,447.5 meters) of the Lunar surface during a full dress rehearsal for the upcoming Apollo 11 landing. Mission Commander Thomas P. Stafford and Lunar Module Pilot Eugene A. Cernan rode Snoopy toward the surface and back, while John W. Young remained in orbit around the Moon aboard the Command and Service Module, Charlie Brown.
Thomas P. Stafford had flown two previous missions in the Gemini Program, Gemini 6 and Gemini 9. Apollo 10 was his third space flight.
John Watts Young flew six space missions: Gemini 3 and Gemini 10, Apollo 10 and Apollo 16, and Space Shuttle missions STS-1 and STS-9. He was to command STS-61J when the space shuttle fleet was grounded following the loss of Challenger. Young has flown 34 days, 19 hours, 39 seconds in space. He made 3 EVAs with a total of 20 hours, 14 minutes, 14 seconds outside his spacecraft.
Eugene A. Cernan had flown Gemini 9 with Stafford. He would later fly Apollo 17 back to the Moon. On 13 December 1972, Gene Cernan was the last man to stand on the surface of the Moon.
