Hubble over Earth

The Hubble Space Telescope heads back toward its normal routine after a week of servicing and upgrading by the STS-109 astronaut crew on board the Space Shuttle Columbia. During this mission, also known as Servicing Mission 3B, astronauts replaced Hubble's solar panels and installed the Advanced Camera for Surveys, which took the place of Hubble's Faint Object Camera, the telescope's last original instrument.
