Which federal agency built America250’s time capsule for burial at Independence National Historical Park?

The National Institute of Standards and Technology built America250’s time capsule for burial at Independence National Historical Park.

NIST is a federal scientific agency within the U.S. Department of Commerce. Its specialists designed and fabricated the capsule to protect documents, objects, and other contributions representing the United States during its 250th-anniversary year.

The project required unusually long-term engineering. The container was designed to withstand underground conditions and preserve its contents for centuries, rather than merely serving as a ceremonial box for a short period.

The National Archives and Library of Congress contributed expertise and materials to the broader project, while the National Park Service was associated with the burial site. Those roles are related but different, which is why NIST is the specific agency sought here.
