"The Astromaterials Acquisition and Curation Office at the Johnson Space Center is tasked to curate NASA's current and future collections of extraterrestrial samples." The website divides the collections into six categories: Rocks and Soils from the Moon, Meteorites from Antarctica, Stratospheric Dust, Solar Wind, Space-Exposed Hardware, and Stardust Mission Samples. Besides learning how to receive and return the samples, users can find newsletters and information on discoveries made using the samples. Researchers can find out meeting dates and sample request deadlines. The website also presents the future sample collections that NASA hopes will help scientists understand the origin and evolution of the solar system and life.
