Summary:
- NASA researchers have solved a 60-year-old mystery about the Earth's atmosphere. They discovered that the upper atmosphere is being heated by energy from the Sun, causing it to expand and contract.
- This expansion and contraction of the upper atmosphere affects the orbits of satellites and space debris, which is crucial information for maintaining the safety of space operations.
- The findings provide valuable insights into the complex dynamics of the Earth's atmosphere and will help improve models for predicting the behavior of the upper atmosphere, which is important for a range of space-based activities.
