Near-Earth Asteroid Scout

Once upon a time, there was a group of people who were interested in keeping an eye on big rocks that might come close to our planet Earth. These big rocks are called asteroids and they can be very dangerous if they hit us.

So they built a special device called the Near-Earth Asteroid Scout or NEAS. This device is like a tiny little spaceship that can travel through space to get a closer look at these asteroids.

When NEAS gets near an asteroid, it uses its special camera to take pictures and gather information about the asteroid, like how big it is and what it's made of.

All of this information is sent back to Earth so that scientists can learn more about asteroids and figure out how to keep us safe from them.

So basically, NEAS is like a little space detective that helps us keep an eye on any dangerous asteroids that might come too close to our home here on Earth!
