True. And we are strongly getting there. Cheap bulk launch is already here compared to 10 years ago. Where will we be in 10 years from now?

Cheap bulk launch is a prerequisite, just like it is for lots of cool big space projects.

Helion doesn't need He-3, their reactors are supposed to produce their own by D-D fusion. And at any rate, the glassy beads of the regolith apparently contain up to about 2 parts per thousand of water. The He-3 content is more like 15 parts per billion.

One example is the recent “room temperature superconductor” hullabaloo that happened over at /r/physics

Lunar polar ice is finite on human timescales? How quickly could we burn through it?

Hi, Astronomer! I've been looking for someone to ask this question for a long time. Could FRBs be coming from different kinds of events (instead of all having the same kind of cause) and are there differences between FRBs (a sort of an FRB "fingerprint" if you will) by which to classify them into different categories?
Like, could some FRBs be the result of neutron star collisions while other FRBs are the result of alien hyperdrives and could we possibly tell the difference based on what we can observe?

Reply to comment by canadave_nyc in Everyone talks about how huge Andromeda will look in the sky billions of years from now. I present you what the Milky Way *currently* looks like in the skies of our neighbor, the Large Magellanic Cloud. We appear absolutely huge in their skies! [Simulated view] by lampiaio
The link seems to be broken.

Can't wait to crush me some beads on the moon for full hydration. I can see the commercials now

besides CS is becoming a GOP hub in the last 20 years, and maybe the AF is fed up with it. OR maybe they want to spread the AF Brain around..

I've watched enough genre movies to know someone is opening a portal to elder god, the devil, rasputin, or something like that this week.

pro tip: DO NOT turn it into a portal-conductive gel

An awful lot of water is locked in the ground anyway. This has very little affect overall. It barely touches what is entering the short term water cycle from the melting of Greenland (which was declared doomed a few years ago)

Crack or fracture? Have you seen how many craters there are on the Moon? Do you think anything man-made can get close to that scale?
No, you can throw the global nuclear arsenal to the Moon and it won't budge, and it'll still be there long after we are gone.

IF renovating is cheaper than moving and rebuilding (And I cannot see a reason why it shouldn't be, then why move it. OTHER than we have a Fuc-ton of bases, Stations, and forts in Colo Sprgs now, and maybe we need to spread the love a bit?
Pete Field is a strategically well-placed base, though, Schriever Space Force Base/Cheyanne-Mnt/Air Acadamy. A bunch of asse ts is located close by.

Peer review really just means it passes basic sense checks by a couple of peers, it isn’t necessarily an exhaustive process. It’s pretty common for papers to get refuted later, in the much more exhaustive long term peer review process that is science, in which a whole scientific community picks the paper apart over time. Unfortunately this can make it difficult for people outside the field to know which papers are currently considered to be authoritative and which aren’t, publication in a top ranked peer reviewed journal means it’s worthy of consideration but could still be completely wrong.

Or rather, according to EMROD, the main loss driver is the conversion to microwaves. Reconversion and transmission appear to be relatively efficient.
