This pendant has flown to the edge of space inside the Arctic Circle. On Jan. 22, 2020, the students of Earth to Sky Calculus visited northern Sweden. Thier mission: To launch a cosmic ray balloon and measure radiation in the polar stratosphere. This Northern Lights pendant went along for the ride. It rose more than 75,000 feet above the frozen landscape near Abisko, Sweden. After the balloon exploded, as planned, the payload parachuted back to Earth, landing near the frozen shore of the Baltic Sea. The pendant had a wild ride, and the students got great data for their atmospheric radiation monitoring program.
Each pendant comes with a greeting card showing the necklace in flight and telling the story of its journey to the edge of space and back.
