Second window opens for Poker Flat rocket launch
Strong wind and other conditions a few weeks ago prevented a rocket launch at Poker Flat Research Range but scientists are making another attempt.
The University of Alaska Fairbanks says scientists want to fire a NASA sounding rocket over a dynamic aurora.
They tried for 16 nights starting Jan. 25 but were confounded by winds that would have pushed rocket stages beyond areas where stages could land. Also, auroras were not appropriate for the test some nights.
The second launch window for the 48-foot, two-stage rocket began Monday night and runs through March 8.
Lead scientist Marilia Samara of the Southwest Research Institute plans to use particle instruments and electric and magnetic field probes to learn more about the sun-Earth energy connection that powers the aurora and affects satellites.
