During its lifetime IUE greatly surpassed the expectations of the original science goals set to justify the mission:

  • To obtain high-resolution spectra of stars of all spectral types to determine their physical characteristics

  • To study gas streams in and around binary star system

  • To observe faint stars, galaxies and quasars at low resolution, interpreting these spectra by reference to high-resolution spectra
  • To observe the spectra of planets and comets

  • To make repeated observations of objects with variable spectra

  • To study the modification of starlight caused by interstellar dust and gas
