Astronaut Scott Kelly returns to Earth after nearly year-long mission in space
Kelly landed back on solid ground in Kazakhstan late Tuesday after spending 340 consecutive days in space, more than any other American. Scientists are eager to study Kelly to examine the effects lengthy space time has on the human body. His twin brother, retired astronaut Mark Kelly, will also be analyzed. In all, Scott Kelly has spent 520 days in orbit across four missions. Ref. USAToday.
Not exacty, the cosmonauts have a very heavy excercise program while on missions. The low gravity is toxic to our bodies and can result up to organ failures. The immediate problems are the degeneration of bone density that lead to osteoporosis.
