NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko returned safely to Earth following 340 days aboard the International Space Station (ISS). During what NASA has called “the year in space,” Kelly and Kornienko participated in scientific investigations designed to capture data on medical, psychological and biomedical challenges faced by astronauts during a long trip in space.
The one year crew mission is the latest step in the space station’s role as a spring board for deep space exploration. On a 30-month mission to Mars, astronauts can expect to experience psychological and physical strain in addition to radiation exposure. Research from the one year mission will shed new light on such issues that will help humans travel farther into space than ever before.
