About this image

The Hubble Space Telescope floats against the background of Earth after a week of repair and upgrade by Space Shuttle Columbia astronauts in 2002.

Hubble's fourth servicing mission gave the telescope its first new instrument installed since the 1997 repair mission – the Advanced Camera for Surveys. It doubled Hubble’s field of view and records information much faster than Hubble’s Wide Field and Planetary Camera 2.
