HST Wide Field Planetary Camera 2

Installed on Hubble in December 1993 along with COSTAR, both designed to correct for Hubble's flawed mirror, WFPC2 was the first instrument to demonstrate the unique capability of astronomical imaging from space.  WFPC2 was returned to Earth, after more than fifteen years in orbit, in May 2009 by STS-125 Servicing Mission 4 (SM4) astronauts.  This historic instrument explored the wonders of the universe and helped rewrite how we think about the universe. WFPC2 is now on display in Space Hall at the National Air and Space Museum in Washington, DC.
