The final launch of a Saturn rocket came on July 15, 1975 as part of the Apollo-Soyuz Test Project. Earlier that day, a Russian Soyuz spacecraft lifted off its launch pad at a Soviet launch site carrying three cosmonauts. Seven and one-half hours later, the U.S. Apollo spacecraft was launched with its crew of American astronauts. Rendezvous and docking of the two ships were accomplished on July 17. The two ships remained docked for two days, conducting joint experiments and exchanging national mementos. In this photograph, astronauts Donald Slayton and Thomas Stafford chat with cosmonaut Alexei Leonov during their visit to the Soyuz Orbital Module.

Slayton (right front) reviews lunar charts with Apollo 11 astronauts Michael Collins (left), Neil Armstrong, and Edwin Aldrin (next to Slayton) during breakfast a short time before the three men launched for the first Moon landing mission. Sharing breakfast with the crew was William Anders (left rear), Lunar Module pilot for the Apollo 8 lunar orbit mission. The Apollo 11 mission launched from the NASA Kennedy Space Center (KSC) in Florida via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. 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.

The original seven Mercury astronauts during training at NASA Langley Research Center Project Mercury. The original seven astronauts trained at NASA Langley Research Center. Chosen from among hundreds of applicants, the seven men were all test pilots. Standing in front of the U.S. Air Force Convair F-106B aircraft, the astronauts are, from left, Lt. M. Scott Carpenter, Capt. Gordon Cooper, Col. John H. Glenn Jr., Capt. Virgil "Gus" Grissom, Lt. Comdr. Walter Schirra, Lt. Comdr. Alan B. Shepard Jr. and Capt. Donald K. "Deke" Slayton. While familiarizing the astronauts with the Mercury set-up, Langley employees helped them to specialize in the technical areas crucial to the overall success of Project Mercury. Langley people also guided and monitored the astronauts activities through the many spaceflight simulators and other training devices built at the Center expressly for the manned space program. In less than three years, Project Mercury proved that men could be sent into space and returned safely to Earth, setting the stage for the longer duration Gemini flights and the Apollo lunar landings.

Mercury astronaut John Glenn and his wife, Annie, pose during a luncheon Feb. 17, 2012, celebrating 50 years of Americans in orbit, an era which began with Glenn's Mercury mission MA-6, on Feb. 20, 1962. Glenn's launch aboard an Atlas rocket took with it the hopes of an entire nation and ushered in a new era of space travel that eventually led to Americans walking on the moon by the end of the 1960s. Glenn soon was followed into orbit by Scott Carpenter, Walter Schirra and Gordon Cooper. Their fellow Mercury astronauts Alan Shepard and Virgil "Gus" Grissom flew earlier suborbital flights. Deke Slayton, a member of NASA's original Mercury 7 astronauts, was grounded by a medical condition until the Apollo-Soyuz Test Project in 1975.
