25 Years of Science in the Solar Wind

In the early 1980s, heliophysicists needed answers. They wanted to learn how to protect astronauts and assets around Earth from the potentially damaging space weather that results from our tumultuous Sun. To do that, they needed to better understand the constantly changing, dynamic space system around our planet — including measurements of the properties of
