The surface of the Sun is 10,000 degrees Fahrenheit, but its outer atmosphere—the corona—soars to some 3.5 million degrees Fahrenheit. Its blistering heat is why no probe has been able to go anywhere it.
But in the middle of next year, NASA will send one to reconnaissance our nearest star. The Parker Solar Probe will get within four million miles of the star with the gravitational assist of seven Venus flybys and make 24 orbits of the star.
The mission is made possible by a shield constructed from a carbon-carbon composite, which will keep the probe’s instruments safe in the 70-degree range.
