This pendant has touched space!
 
On Oct. 15, 2017, the students Earth to Sky Calculus launched a space weather balloon from the Sierra Nevada mountains of central California. Its mission: to measure cosmic rays at the top of Earth’s atmosphere. The payload carried an array of X-ray/gamma-ray detectors, GPS trackers, temperature/pressure sensors and, for fundraising, opalite crystals. With a soothing blue glow that matches the otherworldly color of Earth’s upper atmosphere, these crystals ascended to an altitude of 32 km (105,000 feet) where the balloon exploded. The payload parachuted back to Earth, landing in the Eureka Valley on the outskirts of Death Valley National Park.
 
Each pendant comes with a unique gift card showing the jewelry floating at the top of Earth’s atmosphere. The interior of the card tells the story of the flight and confirms that this gift has been to the edge of space and back again.
