Any serious plans to send a probe into the Sun to explore its depths as far as possible?

What would help a probe last as long as it could and how deep could it get?

Could it even radio or laser out any data?

What about a Sun skimmer?

"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

I wonder if some high-phase angle images with such a camera at fairly close range could show some interesting atmospheric effects. Even the ashen-light if it were to exist. Possibly in the daytime I wonder if there are some subtle colors, either brownish if sulfuric acid absorbs or bluish as Rayleigh scattering contributes along with the clouds.

WISPR wouldn't see color – by "white light" the specs mean a single plane responsive to one wide range of wavelengths, in layman's terms, a black-and-white camera.

The only conceivable advantage over existing datasets would be if it captured Venus' phase angle function from a unique perspective, but Earth-based observations provide basically all angles except the perfectly "full" and perfectly "new" Venus, and we know that Venus Express has covered the "full" phase and multiple orbiters have had the opportunity to image Venus' night side. So I can't see any science coming from this if we're talking about persistent appearance of the planet. Of course, we can never rule out something sporadic light imaging a lightning flash on the night side, although WISPR's quick passes will provide far less chance of that than the long missions of, e.g., Venus Express and Akatsuki.
