Traveling to the Sun: Why Won’t Parker Solar Probe Melt?
The part of the answer here that NASA always seems to skip (perhaps because it&#x27;s not as fun as talking about all the cool heat-resistant technology) is that the vehicle is in an orbit that will only take it into the corona for a short time. While the closest approach is <i>very</i> close, its aphelion is (at closest) about the orbit of Venus. This gives it time to cool down after each corona encounter.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=cMNQeCWT09A" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=cMNQeCWT09A</a>
