Astro-2 - STS-67

Astro-2 is the second dedicated Spacelab mission to conduct astronomical observations in the ultraviolet spectral regions. It consists of three unique instruments - the Hopkins Ultraviolet Telescope (HUT), the Ultraviolet Imaging Telescope (UIT) and the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE). These experiments will select targets from a list of over 600 and observe objects ranging from some inside the solar system to individual stars, nebulae, supernova remnants, galaxies and active extragalactic objects. This data will supplement data collected on the Astro-1 mission flown on STS-35 in December 1990 aboard Columbia.
