Time for the Stars

In Heinlein’s 1956 novel Time for the Stars, he described an experiment in which one identical twin was sent on a space mission while the other stayed at home. NASA has now announced that it will be using a set of twins to examine the effects of prolonged space flight on the human body. Astronaut Scott Kelly, veteran of two shuttle missions and a former ISS Commander, will spend a year aboard the ISS for NASA longest spaceflight ever. His brother, Mark Kelley, who flew four shuttle missions, including as commander of Endeavour‘s final flight, will remain on Earth as the control. Scott Kelly is scheduled to join the ISS crew in March 2014.
