Nothing says “I Love You” like a heart-shaped pendant from the edge of space. On March 17, 2018, the students of Earth to Sky Calculus flew an array of cosmic ray sensors to the stratosphere onboard a giant helium balloon. This pendant went along for the ride. During the 2.5 hour flight, the jewelry experienced temperatures as low as -62 C and air pressures only 0.2% of sea level as the balloon ascended to an altitude of 35.4 km (116,142 feet). After the balloon popped over the snowy Sierra Nevada mountains of central California, the payload parachuted back to Earth, landing the desert near Gemfield, NV, more than 123 km from the launch site.
Each glittering 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.
