STS-125 MCC Status Report #02
A busy day is ahead for the crew members of space shuttle Atlantis as they continue to close in on the Hubble Space Telescope. Today’s wake-up music was “Kryptonite” performed by 3 Doors Down. It was played for pilot Greg Johnson.

The STS-125 crew – Commander Scott Altman, Johnson and mission specialists Michael Good, Megan McArthur, John Grunsfeld, Mike Massimino and Andrew Feustel – will unberth the Orbiter Boom Sensor System with the shuttle’s robotic arm and use it to scan Atlantis’ thermal protection system and the leading edges of the wings. The photos captured by the OBSS will be downlinked to the ground team in Houston for analysis.

Altman and Grunsfeld also will prepare the Flight Support System (FSS) for berthing the telescope on Wednesday. The FSS is a maintenance platform in the aft part of the shuttle’s payload bay that can rotate and tilt the telescope to make access during the mission’s spacewalks easier.

Grunsfeld, Massimino, Good and Feustel will check out the Extravehicular Mobility Units (EMU), which are the spacesuits each of them will use during the mission’s five spacewalks. They will also take a look at the tools they will be using.

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 at the end of the crew’s day, or earlier if events warrant.
