You can't buy this on Amazon. The Astronaut Snoopy Christmas Ornament is only available from the Earth to Sky Store. On Nov. 1, 2024, it flew to the stratosphere onboard a cosmic ray research balloon, reaching an altitude of 89,503 feet above the Sierra Nevada mountains of central California.
 
Created by Hallmark, this rare keepsake floated in the stratosphere for 3 hours while radiation sensors inside the payload gathered data for the students' radiation monitoring project. After the balloon exploded, as planned, the payload parachuted back to Earth, landing in the Piper Mountain Wilderness Area near Death Valley National Park.
 
The ornament comes with a Christmas card showing Snoopy in flight, and certifying that he has traveled to the edge of space and back again.
