Polar space is an area near the North and South Poles of the Earth. Think of the Earth like a big ball, and the North and South Poles are like the very top and very bottom of that ball. When we talk about polar space, we mean the areas around these two points.
Now, the weather at the poles is very different from the weather in other parts of the world. It's very cold and often snows a lot. In fact, some parts of the poles are covered in ice that is many thousands of years old!
Because of this, not many people live near the poles. Instead, scientists and researchers often go there to study and learn about things like the weather, the Earth's climate, and the animals that live in these cold environments.
In addition, there are important things that happen in polar space that affect the rest of the world. For example, the poles have a big impact on global climate and weather patterns. This is because changes in the ice and temperature at the poles can affect things like ocean currents and atmospheric circulation.
So even though polar space might seem far away and not very important to us, it actually plays a big role in the world we live in!
