The mission successfully filmed the moon’s shadow racing toward the balloon, and the subsequent darkness when the balloon itself was beneath the total eclipse.
Earth to Sky Calculus is a “group of kids doing cutting-edge science.” They launch weather balloons from Bishop, Calif., with tethered experiments destined for the stratosphere, more than 10 miles above the ground.
The kids create their own experiments and determine how to successfully launch the balloon. Their research centers on radiation in the upper atmosphere, including fascinating tests with Mars in mind, and developing a biological radiation sensor.
The students are given the “freedom to fail,” according to their website, which promotes real-life learning.
