Think running a marathon is a challenge? Spare a thought for British astronaut Tim Peake, who not only ran this weekend's 26.2 mile London Marathon, but he did the grueling feat strapped to a treadmill 250 miles above Earth.
A Russian Soyuz rocket launched a joint U.S.-Russian crew to the International Space Station Friday (March 18), a space team that includes an astronaut aiming to break an American spaceflight record recently set by NASA's year-in-space astronaut Scott Kelly.
Kelly is retiring after spending nearly a year in space and setting a record for the most cumulative days in space of any American.
His muscles are sore, his joints ache, he’s fatigued and his skin is super-sensitive, the first U.S. astronaut to spend almost a year in space told reporters Friday.
Scott Kelly and Mikhail Kornienko, the first astronaut and cosmonaut to log a year on the International Space Station, left a little bit — or rather a little version — of themselves on the orbital outpost before returning to Earth.
The first-ever yearlong mission aboard the International Space Station ends tonight, and you can watch its final moments live.
More than 18,300 people have applied for 14 or fewer spots in NASA's next astronaut class, shattering the 1978 record of 8,000 applicants.
Although he's almost 250 miles above the ground, NASA Astronaut Scott Kelly still managed to capture a fleeting glimpse of yesterday's Super Bowl matchup.
