Powerful Space Station Spacewalk Previewed.

During a Jan. 12 news conference at the Johnson Space Center in Houston, NASA managers previewed the spacewalk scheduled to take place on Jan. 15 aboard the International Space Station (ISS). During that excursion, Expedition 46 flight engineers Tim Kopra of NASA and Tim Peake of ESA (European Space Agency) will primarily perform work to replace a voltage regulator that compromised one of the station’s eight power channels when it failed last November. Coverage of the spacewalk on NASA TV and the agency’s website, www.nasa.gov, will begin at 6:30 a.m. on Friday, Jan. 15, with the spacewalk scheduled to begin at 7:55 a.m. The spacewalk will be the third in Kopra’s career and the first for Peake.
