Wide Field and Planetary Camera 2 (WFPC2) is the "workhorse"
camera for Hubble. It provides us with pictures of the universe
on a grander scale than any camera to date. The camera can detect
stars over one billion times fainter than we can see with our
eyes. This picture shows astronauts removing the Wide Field
and Planetary Camera 1 (WFPC1), to be replaced by WFPC2 during
the First Servicing Mission in 1993. WFPC1 and WFPC2 were built
at the Jet Propulsion Laboratory in Pasadena, Calif.
