List of Gemini Astronauts
Gemini III, Molly Brown March 23, 1965 Virgil I. Grissom, John W. Young
4 hours, 52 minutes 31 seconds First manned Gemini flight, three orbits.
Gemini IV June 03-07, 1965 James A. McDivitt, Edward H. White II
4 days 1 hour 56 minutes 12 seconds Included first extravehicular activity (EVA) by an American; White's "space walk" was a 22 minute EVA exercise.
Gemini V August 21-29, 1965 L. Gordon Cooper, Jr., Charles Conrad, Jr.
7 days 22 hours 55 minutes 14 seconds First use of fuel cells for electrical power; evaluated guidance and navigation system for future rendezvous missions. Completed 120 orbits.
Gemini VII December 04-18, 1965 Frank Borman, James A. Lovell, Jr.
13 days, 18 hours, 35 minutes 1 seconds When the Gemini VI mission was scrubbed because its Agena target for rendezvous and docking failed, Gemini VII was used for the rendezvous instead. Primary objective was to determine whether humans could live in space for 14 days.
Gemini VI-A December 15-16, 1965 Walter M. Schirra, Jr., Thomas P. Stafford
1 Day 1 hour 51 minutes 24 seconds First space rendezvous accomplished with Gemini VII, station-keeping for over five hours at distances from 0.3 to 90 m (1 to 295 ft).
Gemini VIII March 16, 1966 Neil A. Armstrong, David R. Scott
10 hours 41 minutes 26 seconds Accomplished first docking with another space vehicle, an unmanned Agena stage. A malfunction caused uncontrollable spinning of the craft; the crew undocked and effected the first emergency landing of a manned U.S. space mission.
Gemini IX-A June 03-06, 1966 Thomas P. Stafford, Eugene A. Cernan
3 days 21 hours Rescheduled from May to rendezvous and dock with augmented target docking adapter (ATDA) after original Agena target vehicle failed to orbit. ATDA shroud did not completely separate, making docking impossible. Three different types of rendezvous, two hours of EVA, and 44 orbits were completed.
Gemini X July 18-21, 1966 John W. Young, Michael Collins
2 days 22 hours 46 minutes 39 seconds First use of Agena target vehicle's propulsion systems. Spacecraft also rendezvoused with Gemini VIII target vehicle. Collins had 49 minutes of EVA standing in the hatch and 39 minutes of EVA to retrieve experiment from Agena stage. 43 orbits completed.
Gemini XI September 12-15, 1966 Charles Conrad, Jr., Richard F. Gordon, Jr.
2 days 23 hours 17 min 8 seconds Gemini record altitude, 1,189.3 km (739.2 mi) reached using Agena propulsion system after first orbit rendezvous and docking. Gordon made 33-minute EVA and two-hour standup EVA. 44 orbits.
Gemini XII November 11-15, 1966 James A. Lovell, Jr., Edwin E. Aldrin, Jr.
3 days 22 hours 34 minutes 31 seconds Final Gemini flight. Rendezvoused and docked with its target Agena and kept station with it during EVA. Aldrin set an EVA record of 5 hours, 30 minutes for one space walk and two stand-up exercises.
