Hubble Wide Field Camera 3
The Wide Field Camera 3 was installed on the Hubble Space Telescope during STS-125 and serves as a multiwavelength imaging instrument used by teams from NASA, European Space Agency, and institutes such as the Space Telescope Science Institute and the Goddard Space Flight Center. It replaced earlier instruments alongside servicing activities associated with Space Shuttle Atlantis and contributed to programs involving observatories like Chandra X-ray Observatory, Spitzer Space Telescope, and James Webb Space Telescope collaborators. The instrument enabled observations relevant to projects led by investigators affiliated with Harvard–Smithsonian Center for Astrophysics, California Institute of Technology, and Max Planck Society research groups.
Development began with proposals supported by Space Telescope Science Institute management and funded through programs involving NASA Goddard Space Flight Center procurement and partnerships with Ball Aerospace and Jet Propulsion Laboratory. The design drew on heritage from instruments such as Wide Field and Planetary Camera 2 and Advanced Camera for Surveys, influenced by requirements set during reviews involving National Research Council panels and advisory input from committees with members from European Southern Observatory and Royal Astronomical Society. Key milestones occurred alongside missions including STS-125 and policy decisions by NASA Advisory Council and directives from White House OSTP offices.
The instrument comprises two channels with distinct optical layouts assembled by contractors including Ball Aerospace and tested at facilities such as Goddard Space Flight Center laboratories and the Jet Propulsion Laboratory integration laboratories. The design includes a UV/visible channel and an infrared channel with cold electronics, cryogenic-compatible mounts, and precision mechanisms similar to those employed on instruments for Kepler and Herschel Space Observatory. Structural and thermal interfaces were verified through vibration and thermal-vacuum testing overseen by Marshall Space Flight Center engineers and instrument teams from European Space Agency member countries.
Detector arrays include ultraviolet-sensitive CCDs and a near-infrared detector built on mercury cadmium telluride technology, with filter wheels carrying a suite of broadband and narrowband filters named according to conventions used in observatories like Subaru Telescope and Very Large Telescope. The UV/visible channel uses thinned, backside-illuminated CCDs with characteristics tested against standards from National Institute of Standards and Technology and calibration sources used by Space Telescope Science Institute. The IR detector shares heritage with arrays developed for Wide-field Infrared Survey Explorer and laboratory programs at Jet Propulsion Laboratory. Filter sets were specified to support programs led by investigators at California Institute of Technology, University of Cambridge, and University of California, Berkeley.
Photometric and astrometric performance was calibrated using standard stars in fields studied by Hipparcos and Tycho Catalogue observations, with on-orbit calibration sequences coordinated by Space Telescope Science Institute staff and calibration scientists from European Southern Observatory and National Optical Astronomy Observatory. Distortions and sensitivity drifts were monitored using repeated observations of calibration fields including regions observed by Sloan Digital Sky Survey and referenced to catalogs from Two Micron All Sky Survey and Gaia. Point spread function characterization and charge transfer efficiency corrections used models compared with datasets from Advanced Camera for Surveys and earlier Hubble instruments.
The instrument enabled key legacy programs such as deep field surveys building on the Hubble Deep Field and Hubble Ultra Deep Field initiatives, supported major programs led by teams at Space Telescope Science Institute, European Southern Observatory, and Max Planck Institute for Astronomy, and contributed to cosmological studies aligned with work by researchers from Princeton University, Yale University, and University of Chicago. Observations informed studies of galaxy evolution tied to surveys like COSMOS and informed stellar population research in clusters associated with European Southern Observatory programs. The instrument produced data used in discoveries related to exoplanet atmospheres examined alongside follow-up by Spitzer Space Telescope and preparatory observations for James Webb Space Telescope programs.
Operational support is provided by teams at Space Telescope Science Institute with mission operations coordinated through NASA Goddard Space Flight Center and engineering support from industry partners including Ball Aerospace and Northrop Grumman. Maintenance after installation relied on servicing mission logistics planned during STS-125 and contingency procedures aligned with policies from National Aeronautics and Space Administration mission assurance offices. Data pipeline processing uses software maintained by teams with contributions from Space Telescope Science Institute, European Space Agency, and community tools developed at institutions like California Institute of Technology and University of Arizona.
The instrument's datasets form part of Hubble legacy archives curated by Space Telescope Science Institute and used by researchers at Harvard University, Massachusetts Institute of Technology, and international centers including Max Planck Society institutes. Its technological heritage influenced instrument design for missions managed by NASA and European Space Agency, informed detector development for observatories such as James Webb Space Telescope and ground-based facilities at European Southern Observatory and Keck Observatory, and contributed to training of instrumentalists at Jet Propulsion Laboratory and Goddard Space Flight Center.
