Editing Hubble Space Telescope (section)

== List of Hubble instruments ==
Hubble accommodates five science instruments at a given time, plus the [[Fine Guidance Sensor]]s, which are mainly used for aiming the telescope but are occasionally used for scientific [[astrometry]] measurements. Early instruments were replaced with more advanced ones during the Shuttle servicing missions. COSTAR was a corrective optics device rather than a science instrument, but occupied one of the four axial instrument bays.

Since the final servicing mission in 2009, the four active instruments have been ACS, COS, STIS and WFC3. NICMOS is kept in hibernation, but may be revived if WFC3 were to fail in the future.
* [[Advanced Camera for Surveys]] (ACS; 2002–present)
* [[Cosmic Origins Spectrograph]] (COS; 2009–present)
* [[Corrective Optics Space Telescope Axial Replacement]] (COSTAR; 1993–2009)
* [[Faint Object Camera]] (FOC; 1990–2002)
* [[Faint Object Spectrograph]] (FOS; 1990–1997)
* [[Fine Guidance Sensor]] (FGS; 1990–present)
* [[Goddard High Resolution Spectrograph]] (GHRS/HRS; 1990–1997)
* [[High Speed Photometer]] (HSP; 1990–1993)
* [[Near Infrared Camera and Multi-Object Spectrometer]] (NICMOS; 1997–present, hibernating since 2008)
* [[Space Telescope Imaging Spectrograph]] (STIS; 1997–present (non-operative 2004–2009))
* [[Wide Field and Planetary Camera]] (WFPC; 1990–1993)
* [[Wide Field and Planetary Camera 2]] (WFPC2; 1993–2009)
* [[Wide Field Camera 3]] (WFC3; 2009–present)

Of the former instruments, three (COSTAR, FOS and WFPC2) are displayed in the Smithsonian [[National Air and Space Museum]].<ref>{{Cite news |last=Greenfieldboyce |first=Nell |date=November 18, 2009 |title=Camera That Saved Hubble Now On Display |language=en |work=NPR |url=https://www.npr.org/templates/story/story.php?storyId=120539846 |access-date=April 7, 2022 |archive-date=December 30, 2021 |archive-url=https://web.archive.org/web/20211230042239/https://www.npr.org/templates/story/story.php?storyId=120539846 |url-status=live }}</ref><ref name=":2" /><ref>{{Cite web |date=September 11, 2001 |title=Greater accuracy deepens understanding – Hubble's Faint Object Spectrograph re-calibrated |url=https://esahubble.org/news/heic0112/ |url-status=live |archive-url=https://web.archive.org/web/20220715150042/https://esahubble.org/news/heic0112/ |archive-date=July 15, 2022 |access-date=April 7, 2022 |website=ESA/Hubble |language=en-us}}</ref> The FOC is in the [[Dornier Flugzeugwerke|Dornier]] museum, Germany.<ref>{{Cite web |title=Hubble's Instruments: FOC – Faint Object Camera |url=https://esahubble.org/about/general/instruments/foc/ |url-status=live |archive-url=https://web.archive.org/web/20220504113333/https://esahubble.org/about/general/instruments/foc/ |archive-date=May 4, 2022 |access-date=April 7, 2022 |website=ESA/Hubble |language=en-us}}</ref> The HSP is in the Space Place at the [[University of Wisconsin–Madison]].<ref>{{Cite web |last=Devitt |first=Terry |date=April 21, 2015 |title=Wisconsin contributions helped Hubble Space Telescope soar |url=https://news.wisc.edu/wisconsin-contributions-helped-hubble-space-telescope-soar/ |access-date=April 7, 2022 |website=University of Wisconsin-Madison News |language=en-US |archive-date=December 24, 2021 |archive-url=https://web.archive.org/web/20211224082240/https://news.wisc.edu/wisconsin-contributions-helped-hubble-space-telescope-soar/ |url-status=live }}</ref> The first WFPC was dismantled, and some components were then re-used in WFC3.<ref>{{Cite web |last=Plait |first=Phil |author-link=Phil Plait |date=1999 |title=Hubble's Next Next Generation |url=http://www.badastronomy.com/bitesize/wfc3.html |access-date=April 7, 2022 |website=Bitesize astronomy |archive-date=May 31, 2022 |archive-url=https://web.archive.org/web/20220531010526/http://www.badastronomy.com/bitesize/wfc3.html |url-status=live }}</ref><ref>{{Cite web |date=2001 |title=Hubble Space Telescope Wide Field Camera 3: Capabilities and Scientific Programs |url=https://www.stsci.edu/~WFC3/resources/WFC3-WhitePaper-2001.pdf |access-date=April 6, 2022 |website=Space Telescope Science Institute |archive-date=July 15, 2022 |archive-url=https://web.archive.org/web/20220715150040/https://www.stsci.edu/~WFC3/resources/WFC3-WhitePaper-2001.pdf |url-status=live }}</ref>
