U.S. Navy captain, the famous NASA astronaut Mark Kelly, who set a record stay in space, took over as a U.S. senator from the state of Arizona. He took the place of the late John McCaine.
Kelly has made four space expeditions – shuttle Atlantis flight STS-124, the final flight of the shuttle Endeavour STS-134, as well as two flights to the ISS, during the latter he lived on the station for over a year. His twin brother Scott Kelly is also an astronaut, and they participated in a program to study the long-term effects of space on the human body.
The first astronaut to occupy the post in the US Congress was John Glenn, the first American to orbit around the Earth. He took the chair of Senator Ohio in 1974. Harrison Schmitt, the pilot of the lunar module of the Apollo 17 mission, was a Senator for New Mexico.
Kelly was elected as the deceased Senator John McCain, who was in turn re-elected in 2016. This means that the astronaut’s term of office will end in 2022.
