We’re curious, like a kid who wants to know if there are friends hiding behind the neighbor’s wall. When we look at space, it feels big and empty, but maybe somewhere out there is another place with animals, plants, or even people just like us. We send robots to explore other planets because we want to find out if they have water, air, or something that can help life grow.
Examples
- A kid looks behind the neighbor’s wall wondering if there's someone hiding inside.
- A rover on Mars finds a rock with strange lines, like it was once wet.
