The Space Telescope Imaging Spectrograph (STIS) was installed on the Hubble Space Telescope (HST) during the second servicing mission (SM2) in 1997. STIS is a versatile imaging spectrograph, providing spatially resolved spectroscopy from 1150 to 10300 Å at low to medium spectral resolution, high spatial resolution echelle spectroscopy in the UV, solar-blind imaging in the UV, time-tagging of photons for high time resolution in the UV, and direct and coronagraphic imaging in the optical.
STIS operated on Side-1 electronics until 2004, when it experienced an electronic failure. It remained inoperable until it was repaired successfully in 2009 during Servicing Mission 4 (SM4). STIS has since been operating on Side-2 electronics with all ultraviolet and optical channels.
