    Objectives

    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
