ELI5: Explain Like I'm 5

Jason-1

So, Jason-1 is a really cool satellite that flies around the Earth very high up in space. It is kind of like a giant camera that takes pictures of the ocean and measures how tall the waves are.

But, it doesn't just take regular pictures like your camera or phone. Instead, it uses a special kind of technology called radar. This means that it sends out signals that bounce off the ocean and come back to the satellite.

The Jason-1 satellite is able to use these signals to tell how high the waves are and how choppy the water is. This is really important because it helps scientists and people who work on boats and ships understand how the ocean is changing over time.

Plus, the Jason-1 satellite is always moving around the Earth, so it can look at different parts of the ocean all around the world. It's kind of like having a super power to see what is happening in the oceans from outer space!
