Summary:
- NASA is using small satellites called CubeSats to study the solar wind, which is a stream of charged particles from the Sun that can affect Earth's atmosphere and technology.
- The CubeSats will release small tracers that will help scientists better understand how the solar wind behaves and how it interacts with Earth's magnetic field.
- This research is important for improving our ability to predict and prepare for space weather events, which can disrupt satellite communications, GPS, and power grids on Earth.
