WHAT WE WILL LEARN FROM SCOTT KELLY'S 340 DAYS IN SPACE

After 340 days aboard the International Space Station, astronaut Scott Kelly landed safely in Kazakhstan Tuesday. This is the longest an American has ever traveled in space. Here is a list of how the research obtained by scientists will impact the future of space exploration: http://cbsn.ws/1QM9O7O
  1. What happens to the human body after living in space for a year
    "It's not necessarily uncomfortable, but it is a harsh environment."
  2. Mars exploration
    If the impacts of being in space for 340 days are harsh, imagine a 3-year mission to reach the "Red Planet" and back.
  3. Kelly's genetic structure changes
    Meet Mark Kelly, a former astronaut and Scott Kelly's identical twin brother. Scientists will compare data from both Kellys for a look at long-lasting changes in body, genetic structure.
