Are you looking for a far-out gift? Consider the Sierra Moonrise Pendant. It flew to the edge of space on April 15, 2023, floating on a cosmic ray balloon 117,400 feet above the historically-snowy Sierra Nevada mountains of California.
 
The sterling silver pendant shows the craggy Sierra range with a full Moonstone rising overhead. It makes a great birthday, anniversary or Mother's day gift. The students of Earth to Sky Calculus are selling space pendants to support their cosmic ray ballooning program. Each one comes with a greeting card showing the pendant in flight and telling the story of its journey to the stratosphere and back again.
