Joan Feynman (March 31, 1927 – July 21, 2020) was an American astrophysicist and space physicist. She made contributions to the study of solar wind particles and fields, sun-Earth relations, and magnetospheric physics. She was known for creating a model that predicts the number of high-energy particles likely to hit a spacecraft over its lifetime, and for uncovering a method for predicting sunspot cycles. She was particularly known for illuminating the origin of auroras.
