NASA | The Heliophysics Program

The video explores the impact of the Sun on Earth and the solar system, focusing on space weather and its effects on technology and daily life. NASA's heliophysics research aims to understand solar activity, predict solar storms, and protect satellites and astronauts. The study of the Sun's structure, magnetic field, and solar phenomena like sunspots and solar flares is crucial. Understanding these elements helps us protect infrastructure and improve our knowledge of the solar system.

What is the primary purpose of NASA's fleet of satellites in studying the Sun?
