Poker Flat Rocket Launch (1968 to Present)
The Poker Flat Research Range is located about 50 km North of Fairbanks, Alaska, and it was established in 1968.
It is operated by the Geophysical Institute with the University of Alaska Fairbanks, under NASA contract.
About 250 major rocket launches have taken place from this site, and in 1994, a 16 meter long rocket was launched to help NASA "understand chemical reactions in the atmosphere associated with global climate change."
Similar experiments, but using Chemical Release Modules (CRM), have been launched from Churchill, Manitoba.
In 1980, Brian Whelan's "Project Waterhole" disrupted an aurora borealis, bringing it to a temporary halt.
In March 1989, two Black Brant X's and two Nike Orion rockets were launched over Canada, releasing barium at high altitudes and creating artificial clouds.
These Churchill artificial clouds were observed from as far away as Los Alamos, New Mexico.
