Saturn Apollo Program

The instrument unit for the Saturn V launch vehicle, AS-506, used to propel the Apollo 11 lunar landing mission, is lowered into place atop the third (S-IVB) stage in the vehicle assembly building at the NASA Kennedy Space Center (KSC). Designed by the NASA Marshall Space Flight Center (MSFC), the instrument unit served as the Saturn’s “nerve center” providing guidance and control, command and sequence of vehicle functions, telemetry, and environmental control. The Apollo 11 mission launched from KSC in Florida via the MSFC developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Astronauts onboard included Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin, Jr., Lunar Module (LM) pilot. The CM, “Columbia”, piloted by Collins, remained in a parking orbit around the Moon while the LM, “Eagle’’, carrying astronauts Armstrong and Aldrin, landed on the Moon. On July 20, 1969, Armstrong was the first human to ever stand on the lunar surface, followed by Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished
