On Jan. 6, 2023, the students of Earth to Sky Calculus launched this 18k gold-filled pendant to the stratosphere onboard an Earth to Sky cosmic ray research balloon. At the apex of the flight it floated more than 105,546 ft above the snow-capped Sierras of central California.
Inscribed with the words " I'd Be Lost Without You," the golden pendant is inlaid with 5-star cubic zirconia -- the highest grade. It is totally hypoallergenic and filled with real 18K gold (with a 925 sterling silver base).
During the 2.4 hour flight, the pendant experienced temperatures as low as -61 C and air pressures less than 0.07% of sea level. According to onboard radiation sensors, cosmic ray levels were 100 times Earth-normal as the pendant reached the top of our planet’s atmosphere and touched the edge of space.
After the balloon exploded (as planned), the payload parachuted back to Earth, landing near the Eureka Dunes in Death Valley National Park. The pendant had a wild ride, and the students of Earth to Sky Calculus got great data for their cosmic ray monitoring program.
