Small Steps, Giant Leaps

The Sun is the ultimate source of life in our solar system, a radiant powerhouse that bathes Earth in the energy necessary for everything from photosynthesis to weather patterns. Its warmth and light sustain us. However, the Sun’s influence isn't always benign. Its solar wind—a stream of charged particles—can disrupt our technology, causing communications blackouts and GPS glitches. In this episode, Dr. Joseph Westlake, director of NASA’s Heliophysics Division, joins us to shed light on why the Sun is such a critical focus for space research.
