Spherical Camera at the Edge of Space

On Feb. 27th, Spaceweather.com and the students of Earth to Sky Calculus launched a helium balloon to the stratosphere to monitor increasing levels of cosmic rays. In addition to radiation sensors, the payload carried something special: a spherical camera. Click and drag on the image below to explore California’s Sierra Nevada from an altitude of 115,300 feet–and don’t forget to look up at the balloon!

The camera, a Ricoh Theta S, will probably become a regular part of our cosmic ray payload. Imagery should improve in future flights as the students learn to lower the profile of the camera’s thermal pack–the strange-looking black object in the center of the 3D image. During its flight to the stratosphere, the camera experienced temperatures as low as -65 C. The thermal pack helps keep the camera’s batteries warm in these harsh conditions.

Next week, the camera will take another trip–to Indonesia. The students will be using it to record a total eclipse of the sun on March 9th. Stay tuned for that!
