A sub-orbital sounding rocket is scheduled to launch in February from Poker Flat Research Range when the weather is clear and aurora conditions are active. The rocket, a Black Brant XII, will capture measurements to deduce characteristics about the processes that create the aurora. The project is called the Rocket Auroral Correlator Experiment (RACE). 
The total number of rockets launching from Poker Flat Research Range this season has recently been revised from thirteen to eleven. The reduction is due to the cancellation of a guided rocket project previously scheduled for April that will no longer launch from Poker Flat.
A single, four-stage sounding rocket successfully launched into the aurora at 11:23 p.m. on Sunday, January 13 from Poker Flat Research Range. The rocket, a Black Brant XII, is part of an experiment designed to use Global Positioning System (GPS) radio signals to understand how oxygen emitted from the aurora triggers the expansion of the ionosphere into space, resulting in the formation of radiation belts.
Four rockets are scheduled to launch from Poker Flat when aurora conditions are suitable at night or in early morning hours this January.
Eleven rockets are scheduled for launch from Poker Flat Research Range this winter, with projects ranging from four rockets launched in rapid succession to measure wind in the upper atmosphere in January to an internationally collaborative student rocket launch in March.
Alaska scientist Davis “Dave” Sentman died in December 2011. The man who named “sprites,” colorful discharges that burst upward from thunderclouds, was 66 years old.
Sometimes, after idling in the sky for hours as a greenish glow, the aurora catches fire, erupting toward the magnetic north pole in magnificent chaos that can last for three hours. “Substorms,” as space physicists call them, can happen two or three times each night.
Near a small village in Russia, Marina Ivanova stepped into cross-country skis and kicked toward a hole in the snow. The meteorite specialist with the Smithsonian Museum of Natural History and Vernadsky Institute in Moscow was hunting for fragments of the great Chelyabinsk Meteorite that exploded three days earlier.
On a clear, cold night two winters ago in Fort Yukon, Carl Andersen watched a rocket he helped design pierce the upper atmosphere. He and three other scientists shot pictures as the rocket ejected bright puffs of chemicals in an inverted V formation more than 60 miles up.
On cold winter nights long ago, Harvey Gilliland of Petersburg sometimes woke to the buzz of an alarm mounted on the wall of his kitchen. He kicked off the blanket, got dressed, pulled on his rubber boots, and strolled three city blocks to the building in which he worked.
