today I will write about a unique mission that will go closer to the Sun than ever before (2018).
Something like 3.9 million miles will be the closest approach (should I rant about the imperial units or just convert them?). This means going through the Sun’s corona, that is the legendary region that is apparently not quite well explained, meaning, we do not know why is it hotter than the surface of the Sun, but I am no expert on that.
It is caller Parker Solar Probe, I am thinking that they named it after Matt Parker and the Parker square (anybody?). There are going to be top grade instruments on the board and these need to be carefully protected, aka. when you put 11.5 cm of carbon-composite “desk” around it, it will work.
This thing is going to be fast in its top speed, like 194 km/s, yeah that’s per second which is crazy fast. That would be less than 2 seconds to get from my home to Berlin, fun, I guess it would take some time to accelerate me to that speed (unless my life did not matter).
Another interesting thing that has an effect here and that I mentioned in other post, is that it is hard to hit the Sun since the Earth is traveling very quickly around and just because you get out of its atmosphere does not mean that you fall towards the center of its orbit. Parker Probe will use Venus to slow down to get there without such effort.
