ISS Space Walk Briefing

NASA’s Johnson Space Center in Houston will host
a briefing at 2 p.m. EST (1 p.m. CST) on Tuesday, Jan. 12, to preview the tasks
and preparation for a spacewalk by astronauts living aboard the International
Space Station (ISS).

The briefing and spacewalk will air live on NASA
Television, and be streamed on NASA’s website. Coverage of the spacewalk will
begin at 6:30 a.m. on Friday, Jan. 15, with the spacewalk scheduled to begin at
7:55 a.m.

Expedition 46 flight engineers Tim Kopra of NASA
and Tim Peake of ESA (European Space Agency) will venture outside the space
station’s Quest airlock to replace a failed voltage regulator that compromised
one of the station’s eight power channels last November. The Jan. 15 spacewalk
will be the third in Kopra’s career and the first for Peake, and the 192nd for
maintenance of the space station.

The participants for the Jan. 12 briefing will
include:

·        
Kenneth Todd, ISS
operations integration manager

·        
Royce Renfrew, ISS
spacewalk flight director

·        
Paul Dum, lead spacewalk
officer

Reporters may attend the briefing at Johnson and
other participating NASA centers. Reporters interested in attending by phone
must call the Johnson newsroom at 281-483-5111 no later than 1:45 p.m. on the
day of the briefing.

This will be the 35th spacewalk using the U.S.
Quest airlock, and will focus on replacing a voltage regulator called a
Sequential Shunt Unit that failed Nov. 13, 2015. Additional tasks include
deploying cables for the future installation of an International Docking
Adapter that will accommodate U.S. commercial crew vehicles, and retrieving a
broken light from a truss camera.
