The two Astro missions, Astro-1 on Columbia in 1990, a 9-day mission, and Astro-2 on Endeavor in 1995, a 16-day mission are described. The length of the mission is certainly important for astronomy because we want to look at a lot of different objects, but also we want the maximum amount of exposure time in order to collect data. Astro-1 was not long enough to accomplish everything we wanted to do, but Astro-2 was long enough to be very successful. The Astro instruments and their Principal Investigators (PIs) are listed. There were three ultraviolet telescopes mounted on the IPS, a European instrument pointing system that had previously been used once on the Spacelab for observing the sun. On Astro-1 it was used for the first time to observe stars at nighttime.
