STS-67 was a human spaceflight mission using Space Shuttle Endeavour that launched from Kennedy Space Center, Florida on 2 March 1995.
Astro-2 was 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 supplemented data collected on the Astro-1 mission flown on STS-35 in December 1990 aboard Columbia.
