NASA announced that the second Astro mission, dedicated to astrophysics, would fly aboard the Space Shuttle. The success of the first Astro mission and the ability of the instruments to acquire high-quality scientific data were major reasons for the decision. The following instruments were to fly on Astro-2 to observe the ultraviolet part of the electromagnetic spectrum: the Hopkins Ultraviolet Telescope, which performs spectroscopy; the Ultraviolet Imaging Telescope, which produces images of components of nebulae, stars, and galaxies; and the Wisconsin Ultraviolet Photopolarimeter Experiment, which measures light polarization.
