This wristwatch flew to space and touched the shadow of the Moon.
On Aug. 21, 2017, during the Great American Solar Eclipse, the students of Earth to Sky Calculus launched 11 space weather balloons from the path of totality.They soared into the stratosphere, touching the shadow of the Moon more than 100,000 feet above Earth’s surface. As a fundraiser, one of the balloons carried this wristwatch. With the sun, Earth, and Moon perfectly aligned, the watch entered the space-cold shadow of the Moon … and kept on ticking! It survived temperatures as low as -63 C and cosmic ray dose rates more than 100 times sea level.
Each timepiece comes with a unique gift card showing the watch floating at the top of Earth’s atmosphere and touching the shadow of the Moon. 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.
