Aurora programme

The Aurora Programme is a project started by NASA in the 1970s to study the Earth's aurora, also known as the Northern Lights. Aurora is a beautiful natural phenomenon that happens when electrons from the sun interact with atoms in the Earth's atmosphere. The Aurora Programme probes these interactions by sending special satellites (spacecraft) into the Earth's atmosphere. The satellites measure the temperature, sunlight, and other factors in the Earth's atmosphere, which helps scientists to understand how the aurora works.
