The Discovery Center is located in the city's hospital district and is named after philanthropist Don Harrington.

[3] The Don Harrington Discovery Center is a nonprofit 501 (c)(3) organization that largely relies on the support of its community.

In 1982 the Helium Monument was airlifted by helicopter from I-40 and Nelson to its current site at the Don Harrington Discovery Center.

[8] At this event, the Discovery Center announced that it was accepting suggestions for new items to be placed into the now-empty capsule, which will be opened once more in 2093, 75 years in the future.

Among the items stored in the monument is a passbook to a bank account containing a $10 deposit made in 1968, preserved within the 1,000 year time capsule.
