On June 12, 2018, the students of Earth to Sky Calculus flew a payload-full of moonstone pendants to the stratosphere, 34.1 km (111,877 feet) above Earth's surface. Hand-crafted in the shape of a Celtic love knot, the sterling silver pendants were carried aloft by a helium-filled space weather balloon alongside an array of cosmic ray sensors, which the students use to study atmospheric radiation. After the balloon exploded, as planned, the payload parachuted back to Earth, landing near the Eureka Dunes in Death Valley National Park.
Each premium pendant comes with a greeting card showing the jewelry in flight and telling the story of its journey to the edge of space. Sales of this pendant support the Earth to Sky Calculus cosmic ray ballooning program and hands-on STEM research.
