Flight Day 5

STS-125 Mission Specialist Megan McArthur is positioned to provide heavy support for Atlantis' second session of extravehicular activity from the aft side of the crew cabin, where controls for the remote manipulator system arm, among other important elements, are located.

Via this vantage point she also can maintain visual contact with the two space walkers as they perform work on the Hubble Space Telescope, locked down in the shuttle's cargo bay.
