In another U.S. and Russian joint mission, American Astronaut Scott Kelly and Russian Cosmonaut Mikhail Kornienko will spend 12 months on the International Space Station starting this March, confirms NASA.
During their one year stay in the ISS, Kelly and Kornienko will perform seven research experiments to aid scientists gather significant knowledge on the biomedical, psychological and medical challenges faced by astronauts in long-term space flight.
Among other things, scientists will study differences in vision, functionality, mental health, metabolic processes and physical performance separately from behavioral changes and motor performance.
Another set of tests will be conducted on Kelly and Astronaut Mark Kelly, Scott Kelly's twin brother and also an astronaut who will stay on Earth.
"These investigations will provide broader insight into the subtle effects and changes that may occur in spaceflight as compared to Earth by studying two individuals who have the same genetics, but are in different environments for one year," NASA said in a statement.
Mark Kelly's experience includes piloting Space Transportation System 108 (Endeavour), STS-124 (Discovery Commander) and STS-134 (Endeavour Commander).
Scott Kelly was a crewman of STS-103 in 1999; STS-118 in 2007 and a 159-day stay on the ISS starting on October 7, 2010.
It's going to be a strangely extensive space mission since a typical NASA mission to the ISS lasts no more than six months.
