On Oct. 15, 2022, the students of Earth to Sky Calculus launched a cosmic ray research balloon. This sterling silver moonstone pendant hitched a ride, flying 115,158 feet above the Sierra Nevada mountains of Central California.
 
The moonstone's sterling silver infinity wrap is inscribed with the words "I love you forever."  It makes a great Christmas, anniversary or birthday gift. Each pendant comes with a greeting card showing the mooonstone in flight, and telling the story of its trip to the edge of space and back again. All sales support the student's cosmic ray research program.
