Astronauts Return From Year In Space

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko returned to Earth on March 2 after a 340-day mission aboard the International Space Station.

The nearly one-year mission is the longest amount of time an American astronaut has ever spent in space. (Four Russian cosmonauts have stayed in space longer.)

An important purpose of the mission was to study the effects of long-term space flights on humans. This will help NASA prepare astronauts to travel to Mars some day.

Researchers studied things like how the human body adjusts to weightlessness, isolation, stress and radiation during a long space flight.

Kelly’s twin brother Mark, who is a former astronaut, participated in the same studies here on Earth so scientists could compare their results.

Kelly said he believes it will be possible for astronauts to travel to Mars, even if it takes more than two years to get there. He said he could have stayed in space longer if necessary.

The astronauts carried out about 400 investigations during the mission. One of them was to test Microsoft’s HoloLens – a holographic computer that is worn like a visor and projects images onto the wearer’s environment. On space missions, it can allow people at Mission Control to see what an astronaut sees and guide him or her through a task. It can also project animated illustrations on top of objects that an astronaut is looking at, which may help to explain how to use them.

It can even be used for fun. In their free time, Kelly and his crew mates played a HoloLens videogame that let them fight off a virtual alien invasion.
