Kelly`s time in space has been split between four missions. He is currently in the middle of a nearly yearlong stay aboard the International Space Station, according to the www.cbsnews.com.
When he lands on March 3, 2016, he will have tallied up a total of 522 days, setting the bar very high for the next American record.
On Twitter, Kelly expressed a mix of humility, humor and hope for the space agency's goal to explore deep space.
He`ll break yet another record in just a couple weeks when, on Oct. 29, he reaches his 216th consecutive day in orbit.
"Each additional day in orbit as part of the one-year mission along with cosmonaut Mikhail Kornienko, Kelly will continue to add to his record and to our understanding of the effects of long-duration spaceflight," NASA said in a statement.
The duo`s extended stay is providing crucial data on the effects of space travel on the human body to help prepare for an eventual journey to Mars, in the 2030s.
