Summary

DescriptionWainwright smallballoon1.jpg	English: On June 29, 1998, we launched a balloon from Fort Wainwright, Fairbanks, Alaska. The balloon ascended to about 120,000 feet altitude and traveled from east to west around the North Pole. After about two weeks aloft, the flight was terminated on July 12, 1998, over Victoria Island, Canada, and the payload was recovered. This NSBF map shows the payload trajectory.

The scientific purpose for the flight is to study electron precipitation from the magnetosphere into the ionosphere. This electron precipitation creates the visible northern lights along with X-rays which can be observed with our balloon instrumentation.
