Key Concepts to Understand

Temperature: The thermosphere experiences high temperatures due to the absorption of solar radiation by the few gas molecules present at this altitude. However, despite the high temperatures, the thermosphere would actually feel very cold to our skin due to the extremely low density of the air molecules.
Ionization: The high-energy solar radiation in the thermosphere can cause the ionization of gas molecules, creating a layer known as the ionosphere. This is important for radio wave propagation and communication.
Spacecraft and Satellites: The International Space Station and many other satellites orbit within the thermosphere. Understanding the properties of this region is crucial for the design and operation of these spacecraft.
