Space physics and policy for contemporary society

Space physics is the study of Earth's home in space. Elements of space physics include how the Sun works from its interior to its atmosphere, the environment between the Sun and planets out to the interstellar medium, and the physics of the magnetic barriers surrounding Earth and other planets. Space physics is highly relevant to society. Space weather, with its goal of predicting how Earth's technological infrastructure responds to activity on the Sun, is an oft‐cited example, but there are many more. Space physics has important impacts in formulating public policy. Space physics is the study of Earth's home in spaceSpace physics is broadly relevant to society; space weather is only one of many impactsSpace physics impacts policy decisions in many arenas, from homeland security to space exploration
