A space shuttle mission to deliver a key component that will
enable astronauts to conduct spacewalks on the Earth-orbiting
International Space Station will be the subject of briefings
on Monday, June 25, from NASA’s Johnson Space Center,
Houston.

Designated mission STS-104, Space Shuttle Atlantis is
scheduled for launch no earlier than July 12 to carry a 6.5-
ton Joint Airlock to the station. The airlock will permit
astronauts to perform spacewalks using either American or
Russian spacesuits without the presence of a visiting space
shuttle.

During three spacewalks, shuttle crewmembers will install the
airlock along with four high-pressure oxygen and nitrogen
tanks. This shuttle mission will be the 10th assembly mission
to the International Space Station and will mark the
completion of the second phase of the construction of the
growing complex.

The briefings will begin with an overview of the space
station program at 9 a.m. EDT, concluding with the space
shuttle crew news conference beginning at 3 p.m. EDT.

Round-robin interviews with all five crew members will follow
the joint crew conference, for reporters in attendance at
Johnson, and by phone for those who make advance
arrangements. The round-robin interviews will not be
televised. Space may be limited. Reporters planning to attend
the briefings and participate in the round-robin interviews
must contact the Johnson Space Center newsroom at 281/483-
5111 by close of business Friday, June 22, 2001.

NASA Television is available on GE-2, Transponder 9C, at 85
degrees West longitude, vertical polarization, with a
frequency of 3880 MHz, and audio of 6.8 MHz.
