Each year during mid-July, space historians celebrate one of the most momentous events of the 20th Century. For the first time, humans left Earth to land on the Moon. Many nations around the world have extensively celebrated the mission of Apollo 11 on postage stamps. In the United States, the most iconic commemoratives include works of art by a father and son team – Paul and Chris Calle.
In the summer of 1961, NASA was ready to launch its second piloted spaceflight. It was the next step in Project Mercury’s program to study human capabilities during space travel. Two months earlier, Alan Shepard’s textbook sub-orbital mission made it look easy. But, the splashdown and recovery of the encore flight dramatically demonstrated it is a perilous endeavor requiring attention to detail and extensive preflight training.
In mid-1966, Gemini X continued advancing NASA’s capabilities for operating in space with a record-setting, three-day flight. Two astronauts completed rendezvous with two separate targets, retrieved an experiment package from one and set a new altitude record for human flight. All the objectives were designed as stepping stones in preparation for the Apollo Moon landings to follow.
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.
Jan. 27, 2017, marked the 50th anniversary of the loss of the crew of Apollo 1. A ceremony the day before honored Gus Grissom, Ed White and Roger Chaffee and included reflections on the lessons learned from the tragic event.
