A university in Oregon will use balloons to track eclipse
Portland State University in Oregon will launch four high-altitude balloons equipped with GPS tracking systems and 360-degree video cameras during the upcoming solar eclipse.
The university said Wednesday that the balloons will allow anyone to watch a live stream online as the moon's shadow darkens a large swath of Oregon on Aug. 21.
One balloon will be a part of a larger live streaming project funded by NASA that involves 55 college and school teams throughout the U.S.
Three others are part of a PSU project.
For comparison, the school says a typical airliner reaches a cruising altitude of 39,000 feet.
