Student experiments flown to the edge of space by balloons!

  • A PongSat is an experiment that fits inside of a ping pong ball.
  • These ping pong ball ‘satellites’ are flown to the edge of space by balloon.
  • The PongSats are then returned to the student. It’s an easy and inexpensive way to get students excited about science and engineering.
  • PongSat is a completely free program. All PongSats are flown at no cost to the student or school or group.

There are endless possibilities for experiments that can fit inside a ping pong ball. PongSat’s can be as simple or complex as you want them to be. Experiments can be as simple as comparing how high a ball bounces before and after being exposed to vacuum. The PongSat can carry seeds to see if exposure to cosmic rays effect their growth.

Several small inexpensive computers and other electronic can fit inside a PongSat. These can be used to create a wide range of experiments. Whether carrying a marshmallow to see if it puffs up in the vacuum of near space or an entire sophisticated satellite in miniature, PongSat can create motivation, drive and passion in the classroom.
