Neil A. Armstrong, commander; David R. Scott, pilot
Each Gemini spacecraft launched 2 astronauts. 16 different astronauts flew a total of 10 Gemini flights. The last 4 Gemini flights (Gemini 9 through 12) were commanded by astronauts who had previously flown on an earlier Gemini flight.
Neil Armstrong and David Scott
4 astronauts
The astronauts on the flight were Thomas Stafford, Deke Slayton, and Vance Brand. Deke Slayton had just been restored to flight status after being grounded for numerous years. This was his first flight in space. Tom Stafford flew Gemini 6, Gemini 9, and Apollo 10. He was to command the Soyuz-Apollo flight. Vance Brand was a rookie, so this was his first flight, along with Deke Slayton.
The Gemini spacecraft carried two astronauts to the moon.
There were 2 astronauts on each Project Gemini mission.
All of the manned Gemini flights had two astronauts in them.
I assume you mean after his spaceflights, in which case the answer is the Pacific Ocean, both on his Gemini 8 flight and Apollo 11.
Live and work in space
The first docking in space was performed by Neil Armstrong and Dave Scott aboard Gemini 8 on March 16, 1966. The first docking was to occur during the Gemini 6 flight, but the Gemini 6 Agena docking module failed to reach orbit. Gemini 8 began a slow tumble shortly after docking. Per mission rules, Armstrong undocked from the Agena. When he did, their spacecraft began spinning about 1 revolution every second. The astronauts were on the verge of blacking out when Armstrong finally regained control of the vehicle and stopped the spinning. Had he not been able to gain control, both astronauts would have died in space. It was Armstrong's courage and the calmness with which he handled the situation that caused the NASA planners to choose him to command the first manned landing on the moon.
The Answer is: 10 hours, 41 minutes, and 26 seconds.
The Gemini III spacecraft, carrying Astronauts Gus Grissom (Command Pilot) and John Young, was the first NASA mission to carry 2 members on the same flight. Astronaut Gordon Cooper was the last American to go into Space alone.The Gemini I and II crafts were both test platforms prior to the Manned Flight orbits of the Gemini III.
