43.1 Historical Overview

The development and construction of the Wide Field and Planetary Camera (WF/PC-1) was led by Prof. J.A. Westphal, Principal Investigator, of the California Institute of Technology. The Investigation Definition Team (IDT) also included J.E. Gunn (deputy P. I.), W.A. Baum, A.D. Code, D.G. Currie, G.E. Danielson, T.F. Kelsall, J.A. Kristian, C.R. Lynds, P.K. Seidelmann, and B.A. Smith. The instrument was built at the Jet Propulsion Laboratory, California Institute of Technology. A general overview of the instrument is given by Westphal et al., 1982, "The Wide Field/Planetary Camera," in The Space Telescope Observatory, ed. by D.N.B. Hall, page 28, NASA CP-2244.

The WF/PC-1 was a dual two-dimensional spectrophotometer with rudimentary polarimetric and transmission-grating capabilities. The instrument was designed to operate from 1150 to 11,000 , with a resolution of 0.1 arcsec per pixel (Wide Field Camera, f/12.9) or 0.043 arcsec per pixel (Planetary Camera, f/30) using an array of CCD detectors.

Launched aboard the HST in April of 1990, the WF/PC-1 underwent an initial checkout period, obtained the HST's first light images, and was central to the discovery and characterization of the OTA spherical aberration. In December 1990, the WF/PC-1 detectors were conditioned (UV flood procedure) in preparation for the scientific observing program. During 1991, Science Verification (SV) tests and calibration data were obtained by the IDT concurrent with the Cycle 0 GTO science observations. Starting in mid-1991, GO science observations became a significant part of the WF/PC-1 observing program. The engineering handover of the WF/PC-1 from JPL to STScI was completed in November 1991. Observations for the IDT's SV program were completed in January 1992 and the formal SV Report (Faber et al., 1991) delivered in February 1992. The GO science programs and the STScI calibration programs began during the fall of 1991 and continued successfully until December 1993, when WF/PC-1 was replaced by WFPC2 during the first maintenance and servicing mission.
