Spacewalk continues prepping of ISS for new docking ports.

Working outside the International Space Station for the second time in four days, Expedition 42 Commander Barry Wilmore and Flight Engineer Terry Virts of NASA conducted a spacewalk Feb. 25 to continue rigging cables for the future installation of new docking ports that will greet U.S. commercial crew vehicles in the years ahead. Working around Pressurized Mating Adapter-2 at the forward end of the Harmony module, Wilmore and Virts completed the deployment of the final cables to provide power and data for the new docking adapters that will begin arriving at the station later this year.
