The Space Telescope Imaging Spectrograph (STIS) is an instrument on the Hubble Space Telescope. It combines a camera with a spectrograph, and covers a wide range of wavelengths from the near-infrared region into the ultraviolet. The spectrograph spreads out light gathered by the Hubble Space Telescope so that it can be analyzed to determine things like the chemical composition, motions, and temperatures of astronomical objects. STIS also has an instrument called a coronagraph. It can block light from bright objects in a region being observed, which make sit possible to study fainter targets nearby. STIS was installed on the Hubble Space Telescope during Servicing Mission 2 in 1997. The instrument malfunctioned in August 2004, and was repaired during Servicing Mission 4 in 2009.
