ELI5: Explain Like I'm 5

Aeroshell

Okay kiddo, so imagine you have a toy car that you want to protect. You put it inside a big plastic shell so it won't get damaged if it falls or gets bumped.

Now, imagine we have a very important thing, like a spacecraft or a rover, that we want to protect while it travels through space or lands on another planet. Instead of a plastic shell, we use something called an aeroshell.

An aeroshell is made of two parts: a heat shield and a back shell. The heat shield is the part that faces the planet or atmosphere and protects the spacecraft from getting too hot. It's made of special materials that can withstand very high temperatures, like a superhero shield.

The back shell is the part that faces away from the planet or atmosphere and it protects everything else inside the spacecraft, like the people's food, electronics, and scientific equipment. It's like a backpack that keeps everything safe and together.

The aeroshell is really important because it keeps everything inside the spacecraft safe and protected from the harsh conditions of space or another planet. So just like you have your toy car protected in its plastic shell, we have our important spacecraft protected with an aeroshell.
