The Astromaterials Acquisition and Curation Office at Johnson Space Center is tasked to curate the National Aeronautics and Space Administration's (NASA) collections of extraterrestrial samples. Five collections are currently curated: the Apollo lunar rocks and soils, meteorites from Antarctica, cosmic dust collected in the stratosphere, solar wind samples collected by the Genesis spacecraft, and interstellar and cometary dust samples collected during the Stardust mission. There is also a collection of space-exposed hardware (man-made items that have spent some time in space). Each collection is featured in its own subpage which includes a brief description of collection contents, instructions for requesting and returning samples, and links to additional information. Some of these materials are available upon request for research purposes, for display, or for educational purposes (including disks and thin sections).
