The International Microgravity Laboratory-1, the primary payload on STS-42, included 55 major microgravity experiments conducted over the eight-day flight in Discovery's Spacelab module. STS-56 was the second Atmospheric Laboratory for Applications and Science (ATLAS-2) mission. This nine-day flight also included the deployment and retrieval of the SPARTAN spacecraft.
Most recently, Oswald commanded STS-67, the second flight of the Astro observatory (Astro II), which flew on the Space Shuttle Endeavour in March, 1995. In addition to collecting an unprecedented amount of ultraviolet astronomy data, STS-67 also established a mission duration record for Space Shuttle at 17 days.
