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 don't know, but my best guess would be <poof!!!> before any such probe even got close to the photosphere, so I doubt that any useful data could be gathered even if it could somehow be transmitted through all that RF noise... (need shades just to think about it!!!)
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Solar Probe was supposed to come within 3 solar radii.
I suppose an elaborately shaded craft could get pretty close. A "ball" with instruments could be surrounded with a hemispherical shade with near 100% reflectance held by struts rather far from the craft. Perhaps even a hierarchical tier of such shades could perform even better. Entering the photosphere would instantly annihilate any craft. The velocity of the craft as it hit the outer layers of gas, which would increase rapidly in pressure with depth, would be colossal -- even aside from the radiative heat. |
