Space station power upgrade spacewalks
Expedition 50 astronauts will venture outside the International Space
Station at 7 a.m. EST Jan. 6 and 13 to perform a complex upgrade to the
orbital outpostâ€™s power system. Coverage of the spacewalks will begin at
5:30 a.m. on NASA Television and the agencyâ€™s website
On Wednesday, Jan. 4, NASA TV will air a briefing at 2 p.m. from the
agencyâ€™s Johnson Space Center in Houston to preview the spacewalk
activities. The briefing participants are:
- Kenneth Todd, International Space Station Operations Integration
- Jud Frieling, flight director for Jan. 6 spacewalk
- Gary Horlacher, flight director for Jan. 13 spacewalk
- Troy McCracken, lead battery replacement robotics officer
- Kieth Johnson, lead spacewalk officer
Working on the right side truss of the space station, the crew members will
install adapter plates and hook up electrical connections for six new
lithium-ion batteries that were delivered to the station in December.
Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson
of NASA will perform the first spacewalk Jan. 6. The work will continue
Jan. 13 during the second spacewalk, which will be conducted by Kimbrough
and Flight Engineer Thomas Pesquet of ESA (European Space Agency).
Prior to each spacewalk, the new batteries will be robotically extracted
from a pallet to replace 12 older nickel-hydrogen batteries through a
series of robotic operations. Nine of the older batteries will be stowed in
a cargo resupply craft for later disposal, while three will remain on the
stationâ€™s truss, disconnected from the power grid. The robotic operations
will not air on NASA TV.
This will be the 196th and 197th spacewalks in support of space station
assembly and maintenance. Kimbrough will be designated extravehicular crew
member 1 (EV 1), wearing the suit bearing red stripes for both spacewalks,
the third and fourth of his career.
Whitson will be making the seventh spacewalk of her career and match the
record of NASAâ€™s Suni Williams, for most spacewalks by a woman. She will be
designated extravehicular crew member 2 (EV 2), wearing the suit with no
stripes for the first spacewalk.
Pesquet, who will be making the first spacewalk of his career, will be
extravehicular crew member 2 for the second spacewalk, also wearing a suit
with no stripes.
