New NASA Record Holder For Cumulative Days in Space.

New NASA Record Holder For Cumulative Days in Space.

On August 24, 2016, Station Commander Jeff Williams passed astronaut Scott Kelly, also a former station commander, for most cumulative days living and working in space by a NASA astronaut (520 days and counting). Williams is scheduled to land Sept. 6, 2016, for a record total of 534 days in space. In this photograph taken on June 30, 2016, Williams monitors bowling ball-sized internal satellites known as SPHERES (Synchronized Position Hold, Engage, Reorient, Experimental Satellites) during a maintenance run in the International Space Station's Japanese Kibo Laboratory Module.
