The Wide Field and Planetary Camera 2 (WFPC2) instrument, which was installed in 1993 to replace the original Wide Field/Planetary Camera (WFPC), will be removed to make room for Wide Field Camera 3 (WFC3) during the final Hubble Servicing Mission. Though WFC3 abilities will far exceed WFPC2, many in the space community have a deep affection for WFPC2. WFPC2 will be placed on display at the Smithsonian sometime following the conclusion of SM4.
