How does the SpaceX Dragon capsule return cargo from the ISS?

The SpaceX Dragon capsule is like a spaceship taxi that can carry things back from the International Space Station to Earth.

Imagine you have a lunchbox full of your favorite snacks, and you want to bring it home after school. The Dragon capsule does something similar, it carries stuff from the ISS back to Earth. When it's time to go, it docks with the ISS like two toy trains connecting together.

Then, the Dragon capsule packs up all the cargo, like a lunchbox packed with cookies, fruits, and even experiments, and starts its journey home. It uses engines to push itself away from the ISS, just like how you push your chair back when you're done eating lunch.

Once it's far enough from the ISS, the Dragon capsule fires up its thrusters, which are like little engines that help it zoom through space. It then re-enters Earth’s atmosphere, where it gets really hot, like when you put your hand near a toaster. But it has a special heat shield to protect the cargo inside.

Finally, it lands in the ocean with a splash, just like how you might land in a puddle after jumping from a slide. Then, astronauts or teams on boats can pick up the Dragon capsule and bring its lunchbox of treasures back to Earth!
