After 340 days in space astronauts Scott Kelly and Mikhail Kornienko safely returned to Earth early today. Now the real research begins. Because Kelly has an identical twin, Mark Kelly, who is also a former astronaut, researchers will be able to gain a great deal of knowledge comparing the differences in how their bodies changed over the nearly full year, with one in weightlessness and the other on Earth. However, what I want is longer missions, two or three years long, thus far exceeding what it would take to travel to and from Mars. Only then can we find out if humans will be able to make the journey safely. http://behindtheblack.com/behind-the-black/points-of-information/astronauts-return-after-340-days-on-iss/
