Who is Eugene Parker, namesake of NASA mission to 'touch' Sun?
Launched on Sunday, the Parker Solar Probe is the first NASA mission to be named after a living individual, Dr Eugene Parker. In 1958, the 91-year-old American solar physicist predicted the existence of the solar wind, a stream of charged particles blasted from the Sun. He also theorised why the Sun's corona (outer atmosphere) is hotter than its surface below.
