# 1966 in spaceflight

The year 1966 saw the peak and the end of the Gemini program. The program proved that docking in space and human EVA's could be done safely. It saw the first launch of the Saturn IB rocket, an important step in the Apollo program, and the launch of Luna 9, the first spacecraft to make a soft landing on a celestial object (the Moon).

## EVAs

| Start Date/Time | Duration | End Time | Spacecraft | Crew | Remarks |
| 5 June 15:02 | 2 hours 7 minutes | 17:09 | Gemini IX-A | Eugene Cernan | A complex EVA was planned. Cernan expended four to five times the expected effort, raising his pulse as high as 180 beats per minute. Excess heat and respiration completely fogged visor, causing the EVA to be cut short. Cernan also had difficulty returning to spacecraft and closing the hatch. |
| 19 July 21:44 | 49 Minutes | 22:33 | Gemini X | Michael Collins | Collins performed a stand-up EVA. Instead of climbing completely out of the spacecraft, Collins extended his torso outside the spacecraft to take photos before and after capsule sunrise. Color photography after sunrise was only partly completed due to severe eye irritation of both Collins and Command Pilot Young. Handling the camera proved difficult due to stiffness of spacesuit gloves. |
| 20 July 23:01 | 39 minutes | 23:40 | Gemini X | Michael Collins | Umbilical EVA; with more difficulty than expected, Collins collected the micrometeorite collection package from the outside of Gemini. Then, using the Hand Held Maneuvering Unit, he pushed to the nearby Agena-8 to collect its micrometeorite collection package. Collins then pulled on the umbilical cord to return and re-enter the spacecraft. |
| 13 September 14:44 | 33 minutes | 15:17 | Gemini XI | Richard F. Gordon Jr. | Gordon attached a tether between Gemini and Agena 11 for later orbital mechanics testing. While making the attachment, his work load exceeded the spacesuit cooling system, and his vision became obscured by a fogged visor and sweat in his eyes. Planned activities were curtailed by Command Pilot Conrad and Gordon returned to the spacecraft. |
| 14 September 12:49 | 2 hours 8 minutes | 14:57 | Gemini XI | Richard F. Gordon Jr. | Gordon performed a stand-up EVA. He extended through the hatch to take astronomical photos. Conrad reported the spacewalk was so relaxing they both fell asleep for a moment after sunrise. |
| 12 November 16:15 | 2 hours 29 minutes | 18:44 | Gemini XII | Buzz Aldrin | Aldrin performed a stand-up EVA. Aldrin stood, took UV still photos and 16 mm color movie pictures, collected external experimental samples, and conducted a light exercise routine. |
| 13 November 15:34 | 2 hours 6 minutes | 17:40 | Gemini XII | Buzz Aldrin | First completely successful umbilical EVA, with all objectives achieved. Aldrin was able to control his movements and restrict his work load using techniques developed using underwater zero gravity simulations. He also benefited from experiences of the previous American EVAs and was able to move around the outside of the craft, deploy and recover various experimental packages, install and remove cameras, and practice work techniques using a ratchet-type wrench. |
| 14 November 14:52 | 55 minutes | 15:47 | Gemini XII | Buzz Aldrin | Aldrin performed a second stand-up EVA. He again extended outside the hatch to take photographs and repeat the light exercise experiment. Exertion levels during exercise were comparable to preflight simulations. Equipment and waste food containers not needed for reentry were jettisoned from the spacecraft. |
