At which U.S. government scientific agency was America250’s national time capsule manufactured?

America250’s national time capsule was manufactured at the National Institute of Standards and Technology.

The National Institute of Standards and Technology, commonly called NIST, is a federal scientific agency within the U.S. Department of Commerce. It develops measurement standards and conducts research in areas such as materials, engineering, and technology.

NIST’s role connected the capsule to long-term preservation and technical reliability. The capsule was shown in the institute’s machine shop in Gaithersburg, Maryland, before its burial at Independence National Historical Park in Philadelphia.

The Smithsonian Institution is involved in preserving and interpreting American history, which makes it a plausible mix-up, but it did not manufacture this capsule. NASA is another tempting answer because of its engineering reputation, while the U.S. Geological Survey is known for earth-science research. The project’s fabrication site was specifically NIST.
