Solar Eclipse Balloon Network

Spaceweather.com and the students of Earth to Sky Calculus have developed a balloon payload that can photograph solar eclipses from the stratosphere. This sets the stage for a one-of-a-kind photography experiment: On August 21, 2017, the Moon will pass in front of the sun over the USA, producing a total eclipse visible from coast to coast. We will launch balloons to record the event from a dozen points along the path of totality:

Floating more than 100,000 feet above the clouds, the balloons will have an unobstructed view of the eclipse. From each of a dozen payloads, one camera will point up to record the sun’s ghostly corona while another camera points down to record the passage of the Moon’s dark shadow across the landscape below. When the eclipse is finished, we will combine the footage to create a unique video portrait of an eclipse sweeping across the American continent.

The payload has already photographed a partial solar eclipse in Oct. 2014: images. To test the payload under conditions of totality, a team of students and parents from Earth to Sky Calculus will travel to Indonesia six weeks from now to observe the March 9, 2016, total eclipse: animated map. Stay tuned for news from their expedition!

Readers, would you like to join the Solar Eclipse Balloon Network? Starting now we are recruiting teams of citizen scientists who we will train in the art of high-altitude ballooning to become members of the solar eclipse launch crews. Schools, scout troops, home school families and others are welcome to apply. This is a great way for novices to learn ballooning and to participate in authentic science. We will also be seeking sponsors for the 12 payloads. Contact Dr. Tony Phillips to register your interest.

Solar Eclipse in the Stratosphere

On Oct. 23rd, 2014, just as the New Moon was about to pass in front of the sun, the students of Earth to Sky Calculus launched a helium balloon carrying a Nikon D7000 camera. Their goal: to set the record for high-altitude photography of an eclipse. During a two-hour flight to the edge of space, the camera captured 11 images of the crescent sun. The final picture, taken just a split second before the balloon exploded, was GPS-tagged with an altitude of 108,900 feet:

To put this achievement into context, consider the following: Most people who photographed the eclipse carefully mounted their cameras on a rock-solid tripod, or used the precision clock-drive of a telescope to track the sun. The students, however, managed the same trick from an un-stabilized platform, spinning, buffeted by wind, and racing upward to the heavens at 15 mph. Their photos show that DLSR astrophotography from an suborbital helium balloon is possible, and they will surely refine their techniques for even better photos in the future.

Hey thanks! The students wish to thank AutomationDirect.com for sponsoring this flight. Their $500 contribution paid for the helium and other supplies necessary to get the balloon off the ground. Note the Automation Direct logo in this picture of the payload ascending over the Sierra Nevada mountains of central California:

Another notable picture shows the payload ascending over clouds, which blocked the eclipse at ground level but did not prevent photography from the balloon.

Readers, would you like to sponsor a student research flight and have your logo photographed at the edge of space? Contact Dr. Tony Phillips to get involved.
