Gemini 10: NASA's Epic 1st Double Rendezvous Mission in Photos

Meet the Gemini 10 Crew


Launched on July 18, 1966, the purpose of NASA's Gemini 10 mission was to conduct a double rendezvous and docking test with a two-person crew in orbit. Astronaut John Young (left) was the command pilot, joined by pilot Michael Collins (right). During one of two spacewalks of the three-day mission, Collins became the first person to visit another spacecraft in orbit. The mission also set a new altitude record for human spaceflight.

Altitude Chamber Tests


At the McDonnell Aircraft Corporation's 30-feet altitude chamber in St. Louis, Missouri, the Gemini 10 astronauts get ready for a flight simulation on April 14, 1966.

Ready for the Finale


Onboard the NASA Motor Vessel Retriever, astronaut Michael Collins, the Gemini 10 prime crew pilot, sits in Static Article #5 (SA-5), a water egress trainer, on June 18, 1966. Collins and astronaut John Young, command pilot, were placed in the water inside the SA-5 to practice exiting the craft as well as water survival techniques.

Walking the Ramp


On July 18, 1966, astronaut John Young, command pilot, leads Michael Collins, pilot, as they walk up the Pad 19 ramp. After leaving the Launch Complex 19 suiting trailer during the prelaunch countdown, the Gemini 10 prime crew rode the elevator up to the white room, where the entered their spacecraft before launch.

Successful Launch


NASA's Titan II GLV rocket lifted off on July 18, 1966 at 5:20 p.m. EST (0920 GMT), toting the Gemini 10 spacecraft with astronauts John Young and Michael Collins on board.
