This is a great gift for Douglas Adams fans. "So long and thanks for all the fish," exclaimed the dolphins as they touched the edge of space. On June 20, 2023, the two sterling silver cetaceans flew 104,164 feet above the Sierra Nevada mountains of Central California, hitching a ride onboard an Earth to Sky Calculus cosmic ray balloon.
 
The dolphins are leaping around a heart-shaped moonstone, and suspended from a matching 18-inch sterling silver chain. They come with a greeting card showing the pendant in flight, and telling the story of their trip to the edge of space and back again. All sales support the student's cosmic ray research program.
