WATCH: Commander Scott Kelly Returns to Earth Following Year In Space
After a historic 340 day mission on the International Space Station, NASA astronaut and Expedition 46 Commander Scott Kelly and his Russian counterpart Mikhail Kornienko returned to Earth Tuesday, safely landing in Kazakhstan.
During this record-setting One-Year mission, the station crew conducted almost 400 experiments to not only advance NASA’s mission but to benefit all of humanity too. They conducted a number of studies to advance NASA’s Journey to Mars, including research into how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight.
One of the most engaging parts of the mission allowed the crew to take advantage of the space station’s unique vantage point. With an orbit that covers more than 90 percent of our population, they were able to monitor and capture amazing images of Earth.
While Scott Kelly flew the mission in space, his identical twin brother, former NASA astronaut Mark Kelly, participated in a twin study here on Earth to help scientists compare the effects of space on the body and mind all the way down to the cellular level and Mark talked about his role in the mission.
And as the mission reached an end, Mark knew his brother was preparing to come home.
After the Soyuz capsule left the ISS, the ride back to Earth was successful, the crew landed safely and after a little recuperation time, Scott commented about his historic mission, and the year in space.
With the end of this mission, Scott Kelly has spent 520 days in space, more than any other U.S. astronaut and now back home the twin study will continue to help us prepare for our first trip to Mars.
