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.
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.
Launched unpiloted on May 14, 1973, Skylab was a complex orbiting scientific laboratory that set the stage for the International Space Station of today and long-duration missions to the Moon and Mars in the future. Three crews of astronauts performed microgravity experiments for up to three months in a shirtsleeve environment.
NASA’s Gemini IX mission was another step in developing technology for future spaceflights from Apollo to the agency’s upcoming Artemis Program designed to return astronauts to the Moon followed by exploration of Mars. But, this 1966 mission included developing alternate plans when faced with the unexpected.
The International Space Station has been in operation with research ongoing since Nov. 2, 2000. America’s first space station was Skylab. Launched 48 years ago, it was a complex orbiting scientific laboratory that helped pave the way for permanent operations in low-Earth orbit. It was a program of unparalleled scientific scope that continues to yield highly valuable information about the universe and life within it.
According to an ancient Chinese proverb, “A journey of a thousand miles must begin with a single step.” NASA is preparing to return astronauts to the Moon followed by exploration of Mars, a planet that is 121 million miles from Earth. Those journeys began 60 years ago with a single, 116-mile “step” into space by Alan Shepard on May 5, 1961.
After 168 days in space, NASA astronauts Mike Hopkins, Victor Glover and Shannon Walker, along with Soichi Noguchi of the Japan Aerospace Exploration Agency, or JAXA, returned to Earth landing in pre-dawn darkness at 2:56 a.m. EDT on May 2, 2021 completing the Crew-1 mission. Liftoff atop a SpaceX Falcon 9 rocket took place Nov. 15, 2021, from the agency’s Kennedy Space Center.
A SpaceX Falcon 9 streaked into the early morning sky from NASA’s Kennedy Space Center launching four astronauts to the International Space Station. The Crew-2 mission is the first to fly two astronauts from other nations as part of the agency’s Commercial Crew Program. Liftoff of the Falcon 9 rocket took place at 5:49 a.m. EDT April 23, 2021.
The dream of breaking the “chains of gravity” and traveling through space was realized six decades ago on April 12, 1961. At age 27, Soviet cosmonaut Yuri Gagarin launched into a one-orbit mission around the Earth becoming the first person to venture into the cosmos. While it was another volley in the Cold War with the United States, it marked a historic achievement hailed around the world.
