For the past four summers, Kopernik students have designed, built, launched, and recovered a weather balloon that reached altitudes of over 100,000 feet (nearly 20 miles). In on-board videos they recovered, they saw the sky turn black and water boil at temperatures below freezing in the near-vacuum conditions of maximum altitude. This summer, students will have the opportunity to build on the experience of previous year’s campers and add new experiments using Raspberry Pi computers, GoPro video cameras as well as a slow scan TV experiment to transmit pictures back to earth during the flight. Students will track the balloon’s flight path in real-time, using a beacon equipped with a GPS receiver. The students will have the opportunity to recover the payload on flight day.
