Inside the Meteorite Clean Room at the Smithsonian

Don your clean-room clothing and take a glimpse into the Smithsonian's Antarctic meteorite storage facility in Suitland, Md., where the 15,000 Antarctic meteorites in the national collection are kept under tight security and tight airlocks. These stones are precious because they contain clues to how the solar system formed. Research geologist Cari Corrigan and former meteorite collection manager Linda Welzenbach explain why they have to put on protective gowns before entering the facility and why the meteorites are stored in dry nitrogen.
