On June 27, 2018, a heat shield, the Thermal Protection System was installed on the probe, as it is designed to protect the probe during its travel through the sun's corona to reach as close as 4 million miles from the sun's surface. NASA is reportedly planning to launch the probe in August, 2018.(Photo/Agencies)

NASA's Parker Solar Probe sits inside a cleanroom at Goddard Space Flight Center, Wednesday, March 28, 2018, in Greenbelt, Md., as workers prepare it for launch. The spacecraft, which is scheduled to launch this summer, will travel closer to the Sun than any other spacecraft in history as it attempts to help researchers better understand stars throughout the universe.(Photo/Agencies)
