CHICAGO – NASA has renamed the Solar Probe Plus spacecraft – humanity’s first mission to a star, which will launch in 2018 – as the Parker Solar Probe in honor of astrophysicist Eugene Parker. The announcement was made at a ceremony at the University of Chicago, where Parker serves as the S. Chandrasekhar Distinguished Service Professor Emeritus, Department of Astronomy and Astrophysics.
In 1958, Parker—then a young professor at the university’s Enrico Fermi Institute—published an article in the Astrophysical Journal called “Dynamics of the interplanetary gas and magnetic fields.” Parker believed there was highly energized matter and radiation constantly escaping the sun, and that it affected the planets and space throughout our solar system.
This phenomenon, now known as the solar wind, has been proven to exist repeatedly through direct observation. Parker’s work forms the basis for much of our understanding about how stars interact with the worlds that orbit them.
