Pongsat is an activity where people send up small projects to space inside balloons or rockets that go very high up in the sky. Imagine if you had a big balloon that was as tall as a building and you tied a small toy or a picture to the bottom and let it go up into the sky. Now imagine doing that but instead of a toy, you put a science experiment, like testing how plants grow in space or how different materials react to space conditions. That's what Pongsat is all about!
The word "Pongsat" comes from the words "Pong" and "Satellite". A satellite is a machine that orbits around the Earth and Pong is a game where you hit a ball back and forth with paddles. So in a way, Pongsat means playing a game with projects that go up into space like a satellite!
People of all ages can participate in Pongsat and the projects can be about anything - from testing how ants behave in space to experimenting with materials that can be used to build spaceships. The project is put in a special container that can withstand the pressure and temperature changes of going up into space.
Once the project is ready, the container is attached to the balloon or rocket and sent up into the sky. The balloon or rocket goes very high up and after a while, the container falls back down to Earth with a parachute to safely land. Then the people who sent up the project can analyze the results and see what they found out.
Overall, Pongsat is a way for people to learn about space and science by sending up experiments and projects to see what happens. It's like playing a game with science and who knows what exciting discoveries will be made in the future!
