In June, 2013, some students launched a weather balloon over the Grand Canyon. They attached a GoPro camera and smartphone with GPS capabilities. The balloon climbed to its maximum of 18 and half miles, then bust, falling back to Earth. They lost the balloon.

The GPS was supposed to lead them to the weather balloon after if fell back to Earth,  but where it fell, didn’t have cell phone service so they thought it was lost forever. Recently, two years later, a woman hiker came across the burst balloon, camera and smartphone and using the SIM card was able to track down the owners.

Here’s what the camera caught on its journey.
