SHUTTLE DISCOVERY'S ROLL OFF LAUNCH PAD MOVES TO LATE TUESDAY

CAPE CANAVERAL, Fla. -- Space shuttle Discovery's roll from Launch Pad
39A to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space
Center in Florida on Tuesday, Dec. 21, now is targeted to start at 10
p.m. EST. Discovery is expected to be securely back in the VAB by 5
a.m. Wednesday.

As dates and times of this event are subject to change, updates are
available by calling 321-867-2525.

The move, known as rollback, was delayed early Tuesday morning to
allow technicians to resolve an issue with the leveling system on the
crawler transporter.

The media photo opportunity of the shuttle's move back into the VAB
has been cancelled due to the timing of the operation.

Images of the events will be posted Wednesday on Kennedy's Media
Gallery at:

Video highlights of the rollback will air on the NASA TV Video File
segment Wednesday morning.
