Balloon Cams Will Offer Unparalleled Views of the Total Solar Eclipse
The August 2017 total solar eclipse should be visible to some degree from just about everywhere in the continental United States—that is, if the weather cooperates. But now, even if it doesn't, everyone will be able to watch along, thanks to livestreamed video from balloon cams drifting miles above the Earth.
Astrophysicist Angela Des Jardins of Montana State University (MSU) got the idea to monitor the magnificent cosmic event from the air after reading about an airplane pilot's flight through the path of a 2013 eclipse. She thought her students might enjoy the chance to get an up-close look for themselves.
But what started as a class project quickly, well, ballooned. At last count, teams from more than 50 other schools had joined the Eclipse Ballooning Project. The core of the work remains close to home; MSU students have designed, built, and tested the equipment, and even offered multi-day training for students from other schools. Undergrads in the computer science and engineering programs even created the software that air traffic controllers will use to track the balloons on the big day.
The next step was to get the balloon cam footage to a larger audience. Seeing no reason to think small, Des Jardins went straight to the source, inviting NASA and the website Stream to join the fun. The space agency is now beefing up its website in anticipation of 500 million livestream viewers.
And what a view it should be. The balloons will rise more than 80,000 feet—even higher than NASA's airplane-mounted telescopes.
"It's a space-like perspective," Des Jardins said in a press statement. "From that height you can see the curvature of the Earth and the blackness of space."
Online or outside, Des Jardins says viewers can expect a kind of "deep twilight, with basically a 360-degree sunset" during the eclipse.
She urges everyone to get outside if they can to see the event with their own eyes, but expects the balloon cams will deliver something really special.
"On the ground, an eclipse just kind of happens to you. It just gets dark," Des Jardins told New Scientist. "From the air, you can see it coming and going. I think that perspective is really profound."
