Thermal Control System

A thermal control system is like a mommy or a daddy for things that get too hot or too cold. Just like how parents put a blanket on you when you're cold, or give you a popsicle when you're hot outside, the thermal control system helps keep things at the right temperature.

Imagine you're drinking hot chocolate, but it's too hot to drink. You would blow on it to cool it down, right? In the same way, the thermal control system might use fans or vents to let air flow through and cool down something that is too hot.

On the other hand, if you were outside in the snow and started feeling too cold, you would put on a warm jacket to keep yourself warm. The thermal control system can do something similar by using heaters or insulation to keep something that is too cold, like a spacecraft in space, from freezing.

So, the thermal control system is like a helpful parent that makes sure everything stays at a comfortable temperature.
