It will get more than seven times closer than the current record holder for a close solar pass, a record set by the Helios 2 spacecraft in 1976.
The corona gives rise to the solar wind, a continuous flow of charged particles that permeates the solar system.
"The Parker Solar Probe will help us do a much better job of predicting when a disturbance in the solar wind could hit Earth", said Justin Kasper, a project scientist and professor at the University of MI.
"Today, this is finally possible with cutting-edge thermal engineering advances that can protect the mission on its unsafe journey". He's now 91 and eager to see the solar probe soar. Engineers tried to identifiy the problem, but the launch window - when a spacecraft can take off in the right direction due to the Earth's rotation - closed before they could make progress. Nasa hopes the findings will enable scientists to forecast changes in Earth's space environment.
The probe is going to fly directly into the sun's atmosphere and trace the movement of energy and heat with the particles that form solar winds. At those speeds, it will reach the sun by November and should beam data back by the end of the year.
The spacecraft eventually will run out of fuel and, no longer be able to keep its heat shield pointed toward the Sun, will burn and break apart - except perhaps for the rugged heat shield.
Among the questions NASA is seeking to answer are why the corona is hotter than the sun's surface, as well as why the atmospheres is continually expanding and continually accelerating away from the star.
