Two NASA spacewalkers ventured outside the International Space Station on Wednesday for some heavy-duty orbital remodeling.
NASA astronauts Reid Wiseman and Barry Wilmore began the spacewalk at 8:16 a.m. ET, and are expected to be on the job for six and a half hours. You can watch NASA's coverage of the spacewalk live via Space.com. This is Wiseman's second spacewalk and Wilmore's first.
The agenda for the operation includes removing and replacing a power regulator on the station's starboard truss, NASA said in a statement. That component, known as a sequential shunt unit, failed 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,' NASA said.
Wiseman performed his first spacewalk on Oct. 7 with European Space Agency astronaut Alexander Gerst. The two spacewalks this month are part of a series of extravehicular activities that will help prepare the space station for the arrival of private astronaut taxis that could start flying to the space laboratory by 2017.
Wiseman, Gerst and Wilmore are joined on the space station by three Russian cosmonauts: Maxim Suraev, Alexander Samokutyaev and Elena Serova. The six spacefliers compose the station's Expedition 41 crew.
