History

The University of Alaska had performed auroral research since the 1920s, and when sounding rockets were developed for this purpose, the university decided to build a range for them. The UAF Geophysical Institute leased the land that became the PFRR from the state of Alaska, and the range's facilities were initially completed in 1948 with leadership and vision from

T. Neil Davis Thomas Neil Davis (February 1, 1932 – December 10, 2016) was a professor of geophysics from the University of Alaska Fairbanks and the author of several books. Born in Greeley, Colorado, Davis received his B.S in geophysics from University of Al ...

. PFRR's first supervisor, Neal Brown, directed the facility for 18 years, from 1971 to 1989. In the 1990s, new facilities were built with a $30 million grant provided by Congress. Refurbishment of older facilities is an ongoing project.
