Atlantis continued to move steadily closer to the Hubble Space Telescope
today, and its crew made good use of the time to perform a thorough
inspection of the shuttle's heat shield.

Over the course of the day, five members of the seven-person crew took part
in that survey, which lasted more than seven hours. Commander Scott Altman,
Pilot Gregory C. Johnson, and Mission Specialists Michael Good, Megan
McArthur and Mike Massimino all used the shuttle's 50-foot orbiter boom
sensor system, attached to the shuttle's 49-foot robotic arm, at one point
or another to get an up close look at the surface of the shuttle's belly and
its wing-leading edges and nose cap. The data was sent to the ground, where
it will be carefully analyzed to make sure that the shuttle didn't sustain
any serious damage during Monday's launch.

During that inspection, mission managers noted one area of damage on the
forward part of the spacecraft where the wing blends into the fuselage.
Initially it appears to be very minor and of no concern for the mission,
however the standard expert analysis is underway.

Meanwhile, Mission Specialists John Grunsfeld and Andrew Feustel, with help
from Massimino, checked out the four spacesuits that they and Good will wear
for the mission's five spacewalks.

Before the crew begins their sleep period for the night, Good and Feustel
will be checking out the tools they'll use tomorrow as they rendezvous with
the Hubble, and Altman and Johnson will fire the shuttle's engines to
perfect its course to the telescope.

Rendezvous operations will begin at 6:41 a.m. Central on Wednesday, with the
actual grapple of the telescope using the shuttle's robotic arm scheduled
for 11:54 a.m.

The STS-125 crew will begin its sleep period at 8:01 p.m. and awaken at 4:01
a.m. Wednesday. The next shuttle status report will be issued after that
wake up call or earlier if events warrant.
