Most of the comments so far are about the temperature and the closeness to the sun, and, hey, I get it: those are both amazing to think about. But to me even more amazing is... 0.16% of the speed of light?? Yikes.

Helios2 was half that speed in 1976

I guess everything with a sun slingshot is going to be impressive.

We'd have 1% speed-of-causality probes by now if it meant better war machines but best they can do with the budget

Vaguely related they did capture light moving with a 1 billion frames per second experiment so Femtosecond Photography is definitely some cutting edge stuff.
