EROS Data Center (USGS)

“Mankind’s new microscope in reverse,” the Earth Resources Observation Systems (EROS) Data Center was formally dedicated on this day (Aug. 7) in 1973.

The celebration kicked off the night before with a dinner attended by 700 at the Holiday Inn in Sioux Falls, according to The Daily Republic. Utah Sen. Frank Moss, chairman of the Senate Committee on Aeronautical and Space Sciences, gave the keynote address.

Dedication of the Karl E. Mundt Federal Building took place the following morning with an address from Secretary of the Interior Rogers C.B. Morton. The building is named for South Dakota Sen. Karl Mundt, who worked with local business leaders and the Sioux Falls Development Foundation to purchase the land where the center was built in rural Minnehaha County east of Baltic.
