On Sept. 14, 1966, NASA's Gemini 11 mission set an all-time spaceflight record with the highest altitude ever achieved by a crewed, non-lunar mission, at 850 miles.

On Sept. 14, 1966, NASA's Gemini 11 mission set an all-time spaceflight altitude record when two astronauts reached an orbit of 850 miles (1,368 kilometers) above the Earth. This remains the highest altitude ever achieved by a crewed, non-lunar mission.

Gemini 11 command pilot Pete Conrad and pilot Dick Gordon spent three days orbiting the Earth in their cramped Gemini spacecraft. After launch, they performed the first-ever direct-ascent rendezvous with an Agena target vehicle. 

Once the two spacecraft were adjoined, they used the rocket on the Agena target vehicle to ascend to their record-breaking altitude. They also created a little bit of artificial gravity while in orbit by using their thrusters to rotate the combined spacecraft.

    Just so you know, the X-15 took off from Edwards AFB under the wing of a B-52 & was airdropped over Delamar Dry Lake, Nevada. The flight to the altitude record wasn't planned, but the rocket engine burned for two seconds longer than expected. The test flight was scheduled to peak at 280,000', but actually reached 314, 750' due to the extra rocket burn time.

    Misleading wording. Bob White did not set the world altitude record on July 17th, 1962. Four Astronauts and two cosmonauts had flown higher prior to his flight. One could say it was the highest manned flight of a winged craft. But that's not the wording that was used.

    On this date in 1969, I was part of NASA Apollo Team

    Contributed to Experiments in orbit and on Surface of Moon (ALSEP) etc.also trained astronauts

    Studied containation on and ouside Spacecraft.

    The Moon gave me employment to work for 5 Years on exciting Human Space flight Programs Skylab, Planning of Space Station and Space Shuttle

    "Allegedly, the moon turns green because of its close proximity to Uranus"

    I'm sorry about that. I hear they have been investigating x-rays from the same source. I had no idea. I'll get a doctor to check into it.

    Sorry everyone.

    Sorry...
