Flight Engineers Reid Wiseman (right) and Barry Wilmore spent most of the day on Tuesday, Oct. 14 completing preparations for their 6 ½-hour Oct. 15 spacewalk. The two astronauts set up their spacesuits and tools in the equipment lock of the Quest airlock. Flight Engineer Alexander Gerst of the European Space Agency, who is coordinating spacewalk activities from inside the station, joined Wiseman and Wilmore for a review of spacewalk procedures.
During today’s spacewalk, the astronauts will venture out to the starboard truss of the station to remove and replace a power regulator known as a sequential shunt unit, which failed back in mid-May. The two spacewalkers also will move TV and camera equipment in preparation for the relocation of the Leonardo Permanent Multipurpose Module to accommodate the installation of new docking adapters for future commercial crew vehicles.
