<P> Parker Solar Probe ( previously Solar Probe , Solar Probe Plus , or Solar Probe+ ) is a planned NASA robotic spacecraft to probe the outer corona of the Sun . It will approach to within 8.5 solar radii ( 5.9 million kilometers or 3.67 million miles ) to the ' surface ' ( photosphere ) of the Sun . The project was announced as a new mission start in the fiscal 2009 budget year . On May 1 , 2008 Johns Hopkins University Applied Physics Laboratory announced it will design and build the spacecraft , on a schedule to launch it in 2015 . The launch date has since been pushed back to 2018 . A Delta IV Heavy launch vehicle will enable the mission to become the fastest spacecraft to date . On May 31 , 2017 the probe was renamed after solar astrophysicist Eugene Parker . This was the first time a NASA spacecraft was named after a living person . </P>
