Expedition 47 Commander Tim Kopra of NASA captured this night image of Chicago on April 5, 2016, from the International Space Station. Expedition 47 began March 1, 2016, and ends June 5, 2016, with no spacewalks currently planned.
During Expedition 47, researchers will investigate spaceflight's effect on the musculoskeletal system, the ability of tablets to dissolve in microgravity and how robotics can make exercise equipment smaller to leave more room for crew during a long-duration mission. Such investigations hope to demonstrate how space station crews can help advance NASA's future manned journeys to Mars.
