A keychain from space, Dad needs.
 
It's a far-out Father's Day gift for the greatest dad in the galaxy!
 
On May 29, 2024, the students of Earth to Sky Calculus launched this stainless steel keychain to the stratosphere on board a cosmic ray research balloon. At the apex of the flight it was 101,354 ft above the still-snowy Sierra Nevada mountains of central California.

The keychain comes with a unique gift card showing Yoda floating at the top of Earth's atmosphere. The interior of the card tells the story of the flight and confirms that this gift has been to the edge of space and back again.
