I'm wondering how would they maintain such a large ring of panels and also protect them from space debris that we already have.

>Tardigrades can survive in the vacuum of space

they survived 10 days in vacuum, that doesn't prove they can survive indefinitely, and panspermia is pseduoscience...

First off is Specifically SAID they would never observe each other. That was the entire point of my post. Second off NO F-ING SHIT it's like falling into a planet. Did you think black holes are actually hollow?

I am sorry, I shouldn't be angry. It is fine that you don't known stuff. The reason I am upset is that you didn't know what you were talking to about but you tried to correct me. Next time, if what someone is saying doesn't make sense to you and you aren't an expert in the subject, maybe try asking questions. The answers will tell you if the person knows more than you do or if they are just full of shit.

PLUS that way if they do turn out to be full of shit you get to be the reasonable guy who really embarrassed them when you figure out why they are wrong. And if they turn out to be right you learned something and gain a lot of respect and karma.

Humans landed on the moon in 1969, 1970, 1971, 1972 If we prioritized human space exploration over empty consumerism and pointless self destruction who knows what might’ve been accomplished since then?

Well you misstated it, so that’s why included it. I’ve not reached any conclusions, I’m merely stating that it is very strange to pretend that us humans can say the Milky Way is the only galaxy known to contain life, having barely peered elsewhere in the immensity, and knowing so little. There is also zero evidence that life emerged here. Tardigrades can survive in the vacuum of space, so it is just as likely that life came from elsewhere as it spontaneously emerging here.

Good luck servicing a reactor on the moon as well? What happens if a reactor melts down on the moon?

Redditor for 11 days. Totally legit account. /s

I'm wondering how the panels would hold up to debris impacts on the moon long term. Lots more protection on Earth

Yeah but no way in hell is it six times less mass when you factor in all the equipment required to actually install the panels in a >300 km circumference ring and wire them up to a polar base. Then there's the usefulness of the reactor's waste heat for melting ice.

And good lucking servicing this distributed network of solar panels.

You're missing the point.

The RFP was for 3D printing ground based habitats. Nothing that NASA or the ESA has actually pushed forward in terms of habitats involved 3D printing in low g. The competitions that they actually spent money on were for surface structures.

We're not talking about an actual CNC. The "wasted material" you're talking about is vaporized lunar rock. There's plenty to go around and you get a couple orders of magnitude more volume for your energy input by cutting down into it rather than building up with it. And that's before you even run the math on radiation shielding. Nobody is living off Earth without several meters of mass between them and the outside for any length of time any time soon

I like 3D printing, I've spent half a million on it over the last 10 years or so, but it's overhyped and it gets dropped in as a magic solution for every problem these days.

> decades of stagnation.

So do the moon landings themselves don't count as significant government progress?

Even after that, you'd really consider the launch of countless satellites into low earth orbit which revolutionized earthbound technology including communication and GPS for everyone on the planet, an international space station, countless probes to the furthest reaches of our solar system and probes entering interstellar space, and space telescopes that have revolutionized our understanding of the universe "stagnation"?

You're seriously in a space enthusiasts sub saying that there has been no significant progress in space technology for the last 50 years?

Have a good day.

I'm guessing over-estimates on the lunar nuclear solution, best case estimates for solar panel mass, and sidestepping the problem of volume for that many solar panels. Oh and don't forget to pack 10km (!) of transmission line.

Absolutely. These people want to bring idiotic outdated ideas to space, ridiculous

Agreed. Goes for Arab countries that persecute LGBTQ folks as well.

No, think about it if time started to move in reverse when space collapses, then all the particles that where moving towards each other would have to trace back to the position the had been which would mean that we are back to space expanding and time therefore would have to start moving forward again which would mean space there would start collapsing again and time would have to go in reverse, which would cause expansion and time to move forward, which would cause collapse and time to reverse....... just an endless loop.

The explanation is not necessary, I understand your position, but our understanding of how life emerged is not advanced enough to form any such conclusions based on scale. It is just as likely we're alone. There is zero evidence that life emerged anywhere else.

Israel is too busy f*cking the Palestinians to do anything notable.

I'm wondering how THAT would possibly use less mass

The benefits of 3d printing is you can take raw materials to orbit and create a structure that couldn't exist in 1g conditions with no or little waste. CNC milling creates lots of waste as shavings and chips that are hard to reform into usable materials.

The real trick is getting them all to work with the doors open

As long as you exclude the wires needed to get it to where you need it sure.

If it rings the moon it’s always daylight on half the panels. So I think the takeaway is that half the panels at any given time produce more than fission options.
