A series of press briefings, beginning at 9 a.m. EST
March 21, will preview the Space Shuttle Atlantis mission to
the International Space Station set for liftoff no earlier
than April 4 to deliver the first segment of an external truss
structure. All briefings will be conducted from NASA’s Johnson
Space Center, Houston, and broadcast on NASA Television.

Atlantis will deliver the 43-foot long S0 (S Zero) station
truss — the first of nine truss sections that will support
additional power and cooling systems for future international
laboratories. The STS-110/8A flight will include four
spacewalks by Atlantis’ astronauts to be conducted out of the
station’s Quest Airlock.

Following the crew news conference, round-robin interviews
with the astronauts will be available to reporters at Johnson
and those who make prior phone arrangements by calling
Johnson’s newsroom by 5 p.m. EST Tuesday, March 19. The round-
robin interviews will not be broadcast on NASA TV.

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.
