In order to restore STIS to operational status, astronauts may attempt an on-orbit replacement of one electronics board inside one of its main electronics boxes. The Cosmic Origins Spectrograph (COS) that will be added during Servicing Mission 4, and STIS are highly complementary and would work effectively together to provide a full set of spectroscopic tools for astrophysical research. The STIS instrument's accomplishments include determining the atmospheric composition of an exoplanet as well as spectra and images at ultraviolet and visible wavelengths of the Universe from our solar system out to cosmological distances.    HST SM4 STIS Repair EVA completed and edited animation sequence.
