Hey there! Do you know what a weatherman or weather lady is? They tell you on TV what the weather is going to be like outside. But do you know how they know what the weather is going to be like? They use something called a weather satellite.
A weather satellite is kind of like a big camera in space. It takes pictures of Earth from really high up, so high that it can see the whole planet at once! It takes pictures of things like clouds, storms, and the sun.
The satellite uses special sensors and gadgets to take pictures and measure how hot or cold things are, what direction the wind is blowing, and even how much rain is falling in different places. Then all that information is sent back down to Earth and put into computers.
The computers use all that information to figure out what the weather is going to be like next. For example, if the satellite sees a big storm forming, the computers can tell the weatherman or lady to warn people to be careful and get inside so they don't get hurt.
So, that's what a weather satellite is and what it does. It's like a big camera in space that helps people predict the weather by taking pictures and collecting information about things like clouds, storms, and temperature.
