Spacelab was a reusable laboratory developed by the European Space Agency (ESA) for use in Space Shuttle missions.nThe Spacelab module could be fitted into the Space Shuttle’s cargo bay, transforming the shuttle into a temporary space research station with a range of experiments in various disciplines, including astronomy, biology, physics, and Earth sciences, among others.nThis fragment was part of the STS-58 Spacelab Life Sciences-2 mission, which involved experiments related to physiological responses to microgravity.nnFragment size: Approximately 0.25” x 0.5” (About 0.5 sq. cm) We’ve made every attempt to maintain uniformity, but pieces may vary slightly in appearance.
