Shuttle Processing Note: NASA managers today chose Tuesday, June 4, as the
next opportunity to launch Space Shuttle Endeavour on Mission STS-111/UF2 to
the International Space Station.

Overnight Friday, technicians detected a problem with a regulator on the
left Orbital Maneuvering System pod aboard Endeavour. Managers met Saturday
and elected to replace the component, which moves the launch of STS-111 to
no earlier than Tuesday.

Launch Tuesday will take place during a period extending from 4 – 8 p.m. EDT
and a launch advisory will be issued at approximately 5 p.m. EDT Monday
providing the planned launch time for Tuesday. NASA Television coverage of
the launch will begin at 2:30 p.m. Eastern.

The gaseous nitrogen pressure regulator in the left Orbital Maneuvering
System pod on Endeavour is the same component that showed pressure
differentials during the launch count last Thursday.

The preliminary launch weather forecast for Tuesday shows some improvement
in what has been seen over the last several days, but still indicates the
chance of afternoon and evening thunderstorms and rain showers.

The four shuttle astronauts and three Expedition Five crewmembers will
remain at the Kennedy Space Center until the next launch attempt.
