NASA International Space Station On-Orbit Status 19 August 2016.

Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins concluded their spacewalk at 2:02 EDT. During the five-hour and 58-minute spacewalk, the two NASA astronauts successfully installed the first of two international docking adapters (IDAs).

The IDAs will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft in development under NASA's Commercial Crew Program. Commercial crew flights from Florida's Space Coast to the International Space Station will restore America's human launch capability and increase the time U.S. crews can dedicate to scientific research, which is helping prepare astronauts for deep space missions, including the journey to Mars.

Space station crew members have conducted 194 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 1,210 hours and 46 minutes working outside the station.
