Astronauts Whitson and Tani are outside the ISS this morning, working on a failed solar array part. NASA reports:

U.S. spacewalkers Peggy Whitson, station commander, and Dan Tani, flight engineer, began a spacewalk from the Quest airlock of the International Space Station at 4:56 a.m. EST. Spacewalk tasks include moving to the starboard of the truss structure, removing and replacing a Bearing Motor Roll Ring Module (BMRRM) and inspecting a Solar Alpha Rotary Joint (SARJ). Today’s spacewalk is planned to last 6.5 hours.

Just after 7 a.m. the spacewalkers removed and replaced the BMRRM. The BMRRM, called the “broom”, drives the solar arrays as they tilt towards the sun maximizing power generation. The BMRRM experienced electrical failures in early December.
The spacewalkers are examining the SARJ today after video inspections took place over the weekend providing data for engineers on the ground. The SARJ experienced electrical spikes last year and previous inspections revealed contamination and debris.
