An escape pod is like a secret ship that is hidden inside a bigger ship, like when you have a toy inside another toy. If something happens to the big ship that makes it dangerous to stay inside, the escape pod can be used to get away and be safe.
Inside the escape pod, there are things you need to survive on your own, like food, water, and air. It's like having a little room that you can control and move around in, like a hideout. You can use the controls to fly away from the big ship and land safely somewhere else.
Escape pods are very important because they can help save lives. Just like how your parents teach you to have a plan in case of an emergency, spaceships have escape pods so that the people inside can be safe if something goes wrong.
