Early Monday morning at NASA's Kennedy Space Center in Florida, the rotating service structure at Launch Pad 39A was moved around space shuttle Atlantis, where payload operations will continue throughout the week.

Over the weekend, the payload canister carrying hardware for the mission to service the Hubble Space Telescope was transported to the pad and transferred to the payload changeout room inside the service structure.

At NASA's Johnson Space Center in Houston, the STS-125 astronauts continue to train for the upcoming mission. On Monday, Mission Specialists John Grunsfeld and Andrew Feustel practiced inside the tank at the Neutral Buoyancy Lab for the mission's third spacewalk.
