-— “We Need [ TO SPEND LOTS OF PUBLIC MONEY ] To Go Back”

[crusty old prospector]

Must we? So early in the morning.

[alstewartfan]

Interesting. But it means nothing.

I’m sure there’s a Disney reference in here somewhere, but I’m not depraved enough to think that one up...

> Ariel, a moon of Uranus, might have once harbored an ocean <

Would it be nice to know for sure? Yes.
Is it worth borrowing money to find out? No.

The United States is a debtor nation. So “borrowing money” is certainly the proper term here.

Following the advice of those 4 lads from Liverpool?

“ Uranus’ Moon May Have Harbored a Colossal 100-Mile Deep Ocean"

So what? Who cares? How is this going to affect the life of even one taxpayer other than the aerospace industry that's always salivating over the prospect of swilling more at the public trough?

We Need To Go Back”

No we absolutely do not "need to go back" Let the ones who want to do this cough up the funds or hold a bake sale, but keep your greedy grasping shithooks out of my pocket.

So?

I don’t care about Uranus’ hemorrhoid moon

Uranus is two billion miles from the sun. If it had a large body of water, seems it would be an ice cap, not an ocean.

[GenXPolymath]

Two words: Fusion fuel.

Water ice and liquid this far out in the solar system is original solar system formation water from the super nova that forged all the heavy elements which means it’s loaded with deuterium.

Deuterium is the base of a host of fusion cycles if you have plasma at temps for deuterium + deuterium fusion you have plasma for all the fusion reactions of its fusion products. You need 300 million C for D + D. By the time humans are mining a ice giant moon we will have the tech for 300 million K.

Deuterium(D) + deuterium(D) =
50% neutron + helium3(H3)
50% proton(hydrogen) + tritium(T)

Then the products can fuse too.

D + T = neutron + helium4
D + H3 = proton + helium4
H3 + H3 = proton + proton + helium4

Ultimately you end up with protonium and stable helium 4

The moon has helium3 in the top 2 meters of the regolith holds a million tonnes.

One kg of deuterium from earth’s ocean plus one kg of helium 3 from the moon plus 100 million K = 190,000 gigawatt hours of energy. He3+D is 1/3 the temp of D+D fusion and we have have achieved 100 million K.

This is the way...ion accelerators not magnetic bottles. Humans have accelerated gold and lead to 7 trillion degrees K the path to 300 million K is exactly what this company is doing they plan on D + He3 first or D+T.

Here in the USA a company achieved 217 million C for 24 hours if true. Then that’s also 217000273K... China and Korea both exceeded 100 million C. The Chinese just held for more than 1000 seconds above 100 million K.

[Helium-4 fusion requires a temperature of approximately 100 million Kelvin to overcome the positive charges of the helium nuclei and initiate the triple-alpha process. At this temperature, three helium-4 nuclei fuse, with two first forming an unstable beryllium-8 nucleus, which then fuses with a third helium-4 nucleus to create a stable carbon-12 nucleus, releasing energy. ]

He4+He4 = beryllium8
Beryllium8+He = Carbon12

https://www.yahoo.com/news/us-firm-sets-record-plasma-213547664.html

This is as far as humans likely will ever get. Carbon is the end of the line for fusion without massive gravity wells or artificial gravity if humans ever master gravitons.

A moon of Uranus

Uranus has 29 moons. Make of that what you will, I’m only here for the comments anyway.
