The Parker Solar Probe, a planned NASA robotic spacecraft to probe the outer corona of the Sun, has been scheduled for a July 31, 2018 launch at Cape Canaveral. The probe will approach to within 8.86 solar radii (3.85 million miles) from the 'surface' (photosphere) of the Sun.
The probe has five experiments on board, led by Princeton's David McComas. The Integrated Science Investigation of the Sun (IS☉IS) instrument will measure energetic electrons, protons and heavy ions. The instrument suite is composed of two independent instruments, EPI-Hi and EPI-Lo.
