In the 20 months following the first piloted Gemini mission, NASA astronauts demonstrated the ability to change orbits, perform rendezvous and docking, along with spending up to two weeks in space. Spacewalking, on the other hand, remained an enigma. With only one more Gemini flight on the schedule, solving the problems of working outside a spacecraft would be the primary goal for Gemini XII.
“I tell ya from up here the world is round. It is spectacular. It’s fantastic,” said Gemini XI command pilot Pete Conrad as he and pilot Dick Gordon looked down from their lofty vantage point. Their record-shattering altitude of 850 miles above the Earth was only one highlight of a demanding, three-day mission in September 1966 – 55 years ago.
During the summer of 1971, 50 years ago, three astronauts made the most of three days on the Moon’s surface and in lunar orbit. With the opportunity for more detailed exploration and the addition of “dune buggy”-like transportation, Apollo 15 was the most complex flight to date.
NASA’s Space Shuttle Endeavour first arrived at her home spaceport, NASA’s Kennedy Space Center, on May 7, 1991. Following exactly one year of completing assembly, rigorous tests and processing, the newest orbiter “set sail”into the skies over the Atlantic Ocean. The maiden voyage marked one of the most dramatic examples of the value of humans in spaceflight.
Building on the success of the first piloted Gemini mission, NASA prepared to launch its most ambitions flight to date – Gemini IV. During June 1965, two astronauts would not only stay in orbit four days, one would attempt America’s first spacewalk. It was another example of advancing technology enabling new avenues of exploration.
