The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a space telescope with a 50cm diameter mirror for spectroscopy and polarimetry in the ultraviolet spectral range. It was used in conjunction with other telescopes on the shuttle missions STS-35 (ASTRO-1 in December 1990) [ 1 ] and STS-67 (ASTRO-2 in March 1995).
