The solar innovative mission is scheduled to launch the probe in the summer of 2018. However, it received now a more distinguished name of Parker Solar Probe. In the late twentieth century, Parker theorized that solar coronas could be heated by nanoflares. "You can see the sun is shining, you can see the birds are singing". The preparation of the space craft and this mission began back in the year 2009 and there were around 5 proposals of investigation chosen by the NASA and some other scientists as well. The probe will make 24 elliptical loops through the sun's corona to gather data.
"The solar probe is going to a region of space that has never been explored before", said Parker.
Integrated Science Investigation of the sun (IS☉IS): This investigation makes observations of energetic electrons, protons and heavy ions that are accelerated to high energies (10s of keV to 100 MeV) in the sun's atmosphere and inner heliosphere, and correlates them with solar wind and coronal structures.
To perform these unprecedented investigations, the spacecraft and instruments will be protected from the Sun's heat by a 4.5-inch-thick (11.43 cm) carbon-composite shield, which will need to withstand temperatures outside the spacecraft that reach almost 2,500 degrees Fahrenheit (1,377 degrees Celsius).
Parker Solar Probe will travel at a blistering speed of 430,000 miles per hour and zip in and out of a region where the mercury hits 2,500 degrees Fahrenheit. Parker called it "a heroic scientific space mission", referring to the temperatures and solar radiation to be endured by the spacecraft, and the extreme safeguards taken.
The sun, the hot, glowing ball of gases at the center of our universe, has a surface temperature of 10,000 degrees F. Its atmosphere, or corona, is three hundred times as hot. To accomplish this, NASA is integrating a large enough disc made of carbon composite. The Parker Solar Probe, named after a famous astrophysicist, will analyse the Sun's atmosphere, mainly to understand the mechanics of the solar wind which he had discovered. "There always are", he added.
