Scientists from the University of Alaska Fairbanks and the University of New Hampshire have experiments ready on the launch rails at Poker Flat Research Range north of Fairbanks, and another scientist is waiting in New Hampshire to launch an additional experiment from Poker Flat. The experiments are being flown on NASA sounding rockets. NASA is launching 10 of the suborbital rockets from Poker Flat during January and February. Four successful launches occurred in January. Marc Lessard, a research associate professor at the University of New Hampshire, will use a 65-foot-tall Black Brant XII rocket in a mission called ROPA to gather more information about the power source behind pulsating auroras, which blink on and off in large round patches.
