A NASA spacecraft will aim next year for the "coolest, hottest mission" under the sun. The space agency announced the mission to the sun on May 31, 2017 during a ceremony honoring astrophysicist Eugene Parker, professor emeritus at the University of Chicago. NASA renamed the Solar Probe Plus spacecraft — the first ever mission to a star — after Parker during the event. It is the first time a spacecraft has been named after a living scientist.
