BRIEFING SET TO PREVIEW TWO SPACEWALKS FROM SPACE STATION

WASHINGTON -- NASA will preview a pair of spacewalks involving U.S.,
Russian and Japanese crew members aboard the International Space
Station at 2 p.m. EDT Tuesday, Aug. 14. The briefing will be
broadcast on NASA Television from the agency's Johnson Space Center
in Houston with media questions taken from other participating NASA
locations.

The briefers are:
-- Dina Contella, Expedition 32 lead flight director
-- Kieth Johnson, lead U.S. spacewalk officer

Expedition 32 Commander Gennady Padalka and Flight Engineer Yuri
Malenchenko of the Russian Federal Space Agency have a combined 12
spacewalks between them. They are scheduled to venture outside the
Pirs airlock Monday, Aug. 20, for a six-hour spacewalk. The duo will
install debris shields on the Zvezda service module and move a
telescoping cargo crane from Pirs to the Zarya module.

Flight Engineer Sunita Williams of NASA, a veteran of four spacewalks
on a previous station mission, and Flight Engineer Akihiko Hoshide of
the Japan Aerospace Exploration Agency are scheduled to conduct a 6
1/2-hour spacewalk Thursday, Aug. 30. The spacewalk will focus on
replacing a faulty power routing unit on the station's truss and
running cables for an upcoming Russian laboratory module. Hoshide's
first spacewalk will be the third for Japanese astronauts. This
spacewalk will be the first based from the Quest airlock since July
2011.

To participate in the briefings by telephone, media representatives
must call the Johnson newsroom 15 minutes before each briefing.
Priority will be given to journalists participating in person;
questions by phone will be taken as time permits.
