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.
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.
