Expedition 46 Commander Scott Kelly of NASA and cosmonauts Sergey Volkov and Mikhail Kornienko of Roscosmos landed safely in Kazakhstan on March 2. The landing wrapped up a 340 day mission aboard the International Space Station for Kelly and Kornienko, during which they gathered valuable biomedical data on the long duration effects of weightlessness on the human body that will be used to formulate a human mission to Mars.
NASA officially is beginning work on an astrophysics mission designed to help unlock the secrets of the universe -- the Wide Field Infrared Survey Telescope (WFIRST).

NASA's Orion spacecraft is another step closer to launching on its first mission to deep space atop the agency’s Space Launch System (SLS) rocket. On Jan. 13, 2016, technicians at Michoud Assembly Facility in New Orleans finished welding together the primary structure of the Orion spacecraft destined for deep space, marking another important step on the journey to Mars.
NASA's Lunar Reconnaissance Orbiter (LRO) recently captured a unique view of Earth from the spacecraft's vantage point in orbit around the moon.
A Dec. 2 event with the House of Representatives Committee on Science, Space and Technology, featured a live chat with NASA’s Scott Kelly and Kjell Lindgren from onboard the International Space Station. Kelly and Lindgren answered questions from Texas Representative and Chairperson Lamar Smith and other committee members, about life on the station and the research on the orbital laboratory.
New observations from NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission is providing insight into how Earth is responding to rising levels of heat-trapping gases in the atmosphere, and what this means for our future climate. Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future.
On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance.
