The Space Telescope Imaging Spectrograph (STIS) is a spectrograph, also with a camera mode, installed on the Hubble Space Telescope. Aerospace engineer Bruce Woodgate of the Goddard Space Flight Center was the principal investigator and creator of the STIS.{{cite news|first=Leezel |last=Tanglao |title=Inventor of the camera used on Hubble telescope has died |url=http://www.cbsnews.com/news/astronomer-bruce-woodgate-inventor-of-the-camera-used-on-hubble-telescope-has-died/ |work=CBS News |date=2014-05-01 |accessdate=2014-05-18}}{{cite news|title=Tributes paid to man who changed the face of space |url=http://www.eastbourneherald.co.uk/news/local/tributes-paid-to-man-who-changed-the-face-of-space-1-6047654 |work=Eastbourne Herald |date=2014-05-09 |accessdate=2014-05-18}} It operated continuously from 1997 until a power supply failure in August 2004.{{cite web |first=Maggie |last=McKee |title=NASA attempts to revive Hubble's main camera |url=https://www.newscientist.com/article/dn9457-nasa-attempts-to-revive-hubbles-main-camera/ |work=New Scientist |date=2019-06-30 |accessdate=2019-04-10}} After repairs, it began operating again in 2009. The spectrograph has made many important observations, including the first spectrum of the atmosphere of an extrasolar planet, HD 209458b.

The STIS was installed on Hubble in 1997 during its second servicing mission (STS-82) by Mark Lee and Steven Smith, replacing the High Resolution Spectrograph and the Faint Object Spectrograph. It was designed to operate for five years. On August 3, 2004, an electronic failure rendered STIS inoperable, ending its use 2 years beyond its predicted lifespan. In order to bring it back to operational status, the instrument was repaired by space shuttle astronauts during STS-125, Servicing Mission 4, launched on May 11, 2009.{{cite web|url=http://www.nasa.gov/mission_pages/hubble/servicing/SM4/main/STOCC_update_05172009_FD7.html|title=Space Telescope Operations Control Center — Flight Day 7|date=May 17, 2009|publisher=NASA}} The crew did a long (many hour) EVA to repair the instrument.{{cite web |first=Chris |last=Gebhardt |title=STS-125: Eight hour EVA-4 works STIS repair – Atlantis' TPS overview |url=https://www.nasaspaceflight.com/2009/05/sts-125-eva-4-stis-repair-atlantis-tps-overview/ |work=NASASpaceFlight.com |date=2009-05-17 |accessdate=2019-04-10}}
