Explanation:

All statements are correct.

• The Parker Solar Probe's primary mission is to study the Sun's outer atmosphere (corona), understand why it is hotter than the Sun's surface, and investigate the origins and acceleration of the solar wind.  The Parker Solar Probe is the first spacecraft to "touch" the Sun by entering its corona, achieving a record-setting closest approach of 6.1 million kilometers from the Sun's surface. The spacecraft is equipped with a cutting-edge carbon-composite heat shield, known as the Thermal Protection System, designed to endure temperatures as high as 1,377°C while keeping its instruments at near room temperature. 

Hence option 4th is correct.
