How NASA Studies The Space Near Earth
NASA studies the space around our home planet, a region we call geospace. It might appear empty, but geospace is bustling with electrically charged particles and magnetic fields — all of which can impact the technology and satellites we have flying through it. NASA uses specialized tools to study changing conditions in geospace, known as space weather. Each examines geospace in its own way. Together, they help us visualize, and better understand, the invisible processes shaping the space that is closest to home.
