Seeing double

STS-125 Mission Specialist Andrew Feustel navigates near the Hubble Space Telescope on the end of the remote manipulator system arm, controlled from inside Atlantis' crew cabin. Mission Specialist John Grunsfeld signals to his crewmate from just a few feet away.

Feustel and Grunsfeld were continuing servicing work on the giant observatory, locked down in the cargo bay of the shuttle.
