Yes, Santa gets around. On Nov. 18, 2019, the students of Earth to Sky Calculus flew ten ceramic Christmas ornaments to the edge of space. They show the silhouette of Santa and his reindeer backlit by the supermoon! En route to the stratosphere, the ornaments encountered temperatures as low as -53 C, cosmic ray dose rates more than 100x Earth-normal, and air pressures only 0.15% of sea level.


Each ornament comes with a Christmas card showing the ornament in the stratosphere and telling the story of its flight.
