Solid/liquid Surfaces for Uranus/Neptune, etceteras Options

[qraal]

Hi J.Rehling

Uranus's base is probably molecular fluid and far too hot for a probe. Uranus is rather under-dense and probably has a lot of H2/He in its mix, so there is no base to the "clouds", though it would get too hot with depth for anything to condense. From what I remember the hydrogen becomes a molecular fluid at about a density of 0.83, which should be reached at a pressure of ~280,000 bar or so, and about 1070 K. A bit nasty for a probe. Though at that temperature there might be silicate clouds. Either that or water/ammonia molecular fluid at a somewhat lower pressure & temperature. Sushil Atreya has a paper coming out on that possibility, but it's still nasty.

Hi

I did notice all the replies after I posted. Sorry to sound like an echo.

I remember this idea a probe to the earths core I am still not sure how the probe transmits its data.perhaps there is some revelence to getting to the bottom of things with the gas giants
