On Jan. 8, 2020, NASA astronaut Christina Koch became the first woman from any nation to pass the milestone of 300 days on a single spaceflight. Koch eclipsed the previous record of time in space for a woman, 289 days, on Dec. 28, 2019. NASA’s Peggy Whitson set the mark between Nov. 17, 2016 and Sept. 3, 2017.
American astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko participated in a one-year mission aboard the International Space Station (ISS). Twice as long as a typical crew, the effort was to learn more about the effects of microgravity on the human body.
During the summer of 1965, the United States began to pull even in the space race with the Soviet Union. The eight-day Gemini V endurance mission doubled America’s spaceflight record set two months earlier. It also tested technology that would help make longer missions possible in the future.
In an address to Congress in 1961, President John F. Kennedy challenged the nation to “land a man on the Moon and return him safely to Earth” before the end of the decade. With the flight of Apollo 12, 50 years ago, NASA achieved that goal a second time.
NASA recently marked the 50th anniversary of Apollo 10, the mission that served as the “dress rehearsal” for the first lunar landing two months later. The crew descended to within 47,000 feet of the Moon ensuring all was working as designed prior to making the actual touchdown.
On Dec. 21, 1968, NASA’s Mission Control gave the crew of Apollo 8 approval for TLI — trans-lunar injection — permission to become the first humans to leave Earth orbit. Their destination, 234,000 miles away, was the Moon.
