On September 22, a group of students is going to send send 1000 ping pong balls into outer space. Well, not exactly ping pong balls, but PongSats — small, ping pong-sized science experiments that can range from the super simple (like a marshmallow!) to the highly complex (miniature data logs). When the PongSats return to earth, they bring back video footage, photographs, and data from the upper strata of our atmosphere. That’s pretty far out! It’s also our Project of the Day.
