A new record for the most time spent by an American in space has been set by NASA astronaut Scott Kelly, commander of the International Space Station’s (ISS) Expedition 45 crew. He set the record while participating in a yearlong stay on the ISS along with Russian cosmonaut Mikhail Kornienko. The stay belongs to an experiment to do research on the effects of long term space travel on humans.
On October 13, Kelly broke the 2011 record of astronaut Mike Fincke. It was day 200 of his planned 342 days in orbit. The record of 381 days, 15 hours, and 11 minutes in space made by Fincke included 16 days on the past flight of the shuttle Endeavour and 2 long term stays on the ISS.
Kelly is going to set another record on October 29. It will be the record for the longest consecutive stay of an American on the ISS, 216 days. The record will break the one set by Expedition 14 commander Michael Lopez-Alegria, who stayed for 215 days in orbit in 2007.
With this Kelly is going to become the first astronaut, who holds the records for spending the longest time in space both on a single mission and cumulatively in different missions since Expedition 4 flight engineer Carl Walz.
Both these records were held by Walz in 2002 when he spent 196 days on a single mission and 230 days in space cumulatively.
