The Hopkins Ultraviolet Telescope performed successfully aboard the Astro-1 space shuttle mission and obtained a large number of spectra bearing on a wide range of astrophysical topics in its brief 9 day flight. Observations of the DA white dwarf G191-B2B have been used to derive a photometric calibration curve for HUT that is believed accurate to better than %. The data obtained by HUT represent the first extensive spectrophotometric observations in the 912--1216 Å band to bridge the gap between the Copernicus spectroscopy of bright stars at high resolution, and the Voyager observations at much lower resolution. It is expected that improvements to the shuttle spacelab systems, especially the IPS performance, together with a longer duration flight and a moderate improvement of the spectrograph efficiency, may enable HUT to obtain nearly an order-of-magnitude more data on the Astro-2 mission, now planned for launch in 1994.
