After 383 cumulative days in space (and counting!), NASA astronaut Scott Kelly has broken the record for the longest time spent in space by an American.

"Records are meant to be broken. Look fwd to one of my colleagues surpassing my end 500+ days on our #JourneyToMars!" Kelly said in a tweet regarding his accomplishment.

Kelly's time in space spans four missions. He first traveled into space in December 1999. During the 8-day STS-103 mission, Kelly and his colleagues serviced the Hubble Space Telescope.

In August 2007, he returned to space for 12 days aboard the Space Shuttle Endeavor as the commander of STS-118, a mission to service the International Space Station.

Three years later, he returned to the International Space Station as an Expedition 25 flight engineer. During a stint that totaled 159 days, Kelly eventually assumed control of the ISS during Expedition 26.

Presently, Kelly and Russian cosmonaut Mikhail Korniyenko are spending a year in space as part of a mission to study the long-term impacts of spaceflight on the human body.

The previous record for longest time spent in space by an American was held by astronaut Mike Fincke, who spent 382 days in space over three missions. Russian cosmonaut Gennady Padalka has spent more days in space -- 879 -- than any other human.
