On June 20, 2021, this 16 oz. ceramic Lt. Uhura mug flew to the stratosphere onboard an Earth to Sky Calculus cosmic ray research balloon. At the apex of the flight, it floated 92,192 feet above the Sierra Nevada mountains of central California. After the balloon exploded (as planned), Uhura parachuted back to Earth, landing on Coyote Flats, a high plateau overlooking Bishop CA.You can have this collector's item for $170.10 (the serial number of the Enterprise divided by 10). Each mug comes with a greeting card showing the item in flight and telling the story of its journey to the edge of space and back.
