Shuttle Processing Note: NASA managers today chose Wednesday, June 5, as the
next opportunity to launch Space Shuttle Endeavour on Mission STS-111/UF2 to
the International Space Station.

Mission managers met Sunday morning to assess the progress of changing a
regulator in the left Orbital Maneuvering System pod aboard Endeavour. This
gaseous nitrogen pressure regulator is the same component that showed
pressure differentials during the launch count last Thursday. Because of
the uniqueness of the change out and the work to build a test fixture
required, launch of Endeavour on the STS-111/UF2 mission to the
International Space Station has been moved to Wednesday between 4 and 8 p.m.
Eastern time. A launch advisory will be issued at approximately 5 p.m. EDT
Tuesday providing the preferred launch time for Wednesday.

NASA Television coverage of the launch will begin at 2 p.m. Eastern.

The long-range weather forecast for Wednesday shows some improvement in what
has been seen over the last several days near the time of launch, but still
indicates the chance of afternoon and evening thunderstorms and rain
showers.

The four shuttle astronauts and three Expedition Five crewmembers spent the
weekend relaxing and reviewing their flight plan to be executed once on
orbit.

Aboard the ISS, the Expedition Four crew was notified of the additional
delay shortly after the meeting by Mission Control and took the news in
stride.
