How do satellites help us?
Right now, thousands of satellites are circling Earth like a invisible carousel in the sky. They're up there doing jobs most people never think about — watching storms brew over the ocean, bouncing your video call to Tokyo, helping your pizza delivery driver find your house. Let's follow one orbit and see what they're actually doing.
First job: being the world's eyes. Weather satellites stare down at clouds, measuring their temperature and how fast they're spinning. When a hurricane starts forming over warm ocean water, these satellites spot it days before it reaches land. Meteorologists watch the satellite pictures like a slow-motion movie — "that swirl is getting organized, we should warn people on the coast." Without satellites, a hurricane would be a surprise that just shows up.
