Well that's dumb. Solar power during the very long day could power operations and charge batteries for ops during the long night. Trump's admin is so anti-renewables that they'd rather build a nuke plant than take advantage of solar. I'm only surprised they aren't trying to figure out how to build a coal plant up there.

A small reactor like what we use in submarines or our aircraft carriers would probably be the best tool for the job on the moon. They are small and require minimal maintenance (within their fairly long lifespan) and they produce enormous amounts of power.

How much weight in solar panels would it take to produce what a reactor could?

Would a single panel on the moon last more than 20 years?

How do we decommission panels on the moon?

(forgot about batteries)... all of these things IDEALLY will come back down to Earth some day so the fewer things we put on the moon in the first place the better

And we can just shoot the spent fuel into the sun!

[–] teft@piefed.social 5 points 5 days ago (1 children)

It's more efficient to launch it out of the solar system. Less Ξ”v required.

[–] Ptsf@lemmy.world 6 points 5 days ago

Imagine being the first alien civilization to find remnants of ancient human culture in space, and it's a cancerous death rock screaming radiation... Haha

Having enough batteries to survive two weeks of darkness would weigh a lot more than a nuclear reactor.

[–] burble@lemmy.dbzer0.com 5 points 5 days ago

Solar might only be viable at some polar regions where you can get full sunlight with no day/night cycle. 2 weeks of night time to survive on batteries would be rough.

[–] JeromeVancouver@lemmy.ca 5 points 5 days ago (1 children)

My first thought was, that is pretty awesome.

After thinking about it and reading your comment my thoughts are, don't nuclear reactors on earth take years to build? This process seems extremely difficult. Solar power makes so much sense.

[–] Badabinski@kbin.earth 7 points 5 days ago

NASA has already built prototype reactors for this purpose. They're small, highly efficient, and incredibly safe. The main thing is that the scale of power generation is vastly different here. A terrestrial nuclear reactor is generating hundreds of megawatts of electricity from (up to) gigawatts of thermal energy. We don't need that much power for a small moon base. 10-100 kilowatts would be just fine, especially if it's serving to supplement solar panels or batteries.

Nuclear power does have a really valid use-case in space. Solar panels should always be used first and foremost, but there are just times where they're not going to be enough.

Oh boy I can't wait for the SpaceX rocket carrying the uranium to explode on the launchpad.

[–] CitizenKong@lemmy.world 3 points 4 days ago

Don't worry, the radiation will only be 3.6. No great, not terrible.

[–] itsathursday@lemmy.world 16 points 5 days ago (2 children)

Please don’t fuck up the moon. It’s big and boring but it does a lot by just being there and doing β€œnothing”.

[–] CarbonIceDragon@pawb.social 16 points 5 days ago (2 children)

Literally how could we? It's a big rock, it has no ecosystem whatsoever, and any effort to live there someday would require environmentally sealed and radiation resistant structures. Degrading what it does to earth would require significantly altering it's mass or orbit, which would require an amount of energy that isn't in the cards for a long time to come even optimistically.

[–] thisbenzingring@lemmy.sdf.org 4 points 5 days ago (1 children)

someone could muck up the viewable side surface but it'd take forever to do that

it would be cool seeing a dot on it and knowing it's a human structure that's definitely doing energy in space wrong but still a cool endeavor

[–] burble@lemmy.dbzer0.com 14 points 5 days ago

If a moon with city lights doesn't awaken the sci-fi nerd in everyone then I don't know what to say.

Let's just agree to keep the dark side dark for telescopes.

[–] 0_o7@lemmy.dbzer0.com 2 points 5 days ago* (last edited 5 days ago)

Trying to set the moon up as a military base or start an arms race to control the most of it, is kind of ruining it, but hey move fast and break things, is what led us to fuck things up here. Let's go and try it on the nearest celestial object too. That's the most logical thing to do.

And just because the technology and resource to manage it better isn't here yet, why not start early? That works out just as planned every time on earth. It would be a piece of cake on the moon.

President Donald Trump has prioritized U.S. dominance in what one senior NASA official described to Politico as "the second space race."

You guys never learn and it shows.

[–] 9tr6gyp3@lemmy.world 3 points 5 days ago

I expect the tides to cease and a lot of meteor showers in the future.

[–] MTK@lemmy.world 6 points 5 days ago (2 children)

Lol, the US is currently contracting SpaceX, best known for making really cool, futuristic and expensive bombs.

By fast-track do they mean 500 years instead of 1000?

[–] Ptsf@lemmy.world 7 points 5 days ago (2 children)

I feel that's not fair to some of the engineers at SpaceX. A prior head of NASA is quoted multiple times saying reusable first stages would be impossible, only 5-10 years before SpaceX landed 2 falcon heavy first stages simultaneously. Space is hard. A lot of test and production space vehicles do explode. Several of the challenger missions for example. Clearly Elon is a rube, but that doesn't imply everyone under him is... So maybe just try to make your point without disrespecting and disregarding the work of some of the brightest engineers on the planet?

And were they reused?

[–] Sconrad122@lemmy.world 6 points 5 days ago

Yes, both B1023 and B1025 had flown before when they flew as the FH side boosters, so they were reused

[–] MTK@lemmy.world -2 points 5 days ago (1 children)

It is hard, yet the space shuttle program did just fine and didn't burn 3 billion dollars of tax payer money for spacex to say "well, it got off the launch pad before exploding, success!"

No hate to the engineers there, i'm sure any good they do is overshadowed by the nazi drug addict that employees them.

[–] remon@ani.social 3 points 5 days ago (1 children)

The space shuttle is literally the deadliest space vehicle to ever exist. And (adjusted for inflation) cost 1.5 billion dollar per launch ... what are you even talking about?

[–] MTK@lemmy.world 0 points 4 days ago* (last edited 4 days ago) (1 children)

135 missions, only 3 failures with a total of 14 astronauts dead. Spacex had 9 launches and 5 failed.

[–] remon@ani.social 3 points 4 days ago* (last edited 4 days ago) (1 children)

135 missions, only 3 failures with a total of 14 astronauts dead.

Yeah ... that is bad. In fact, the worst track record for any manned space vehicle.

Also the comparison to Starship is stupid as it's still in development. And Falcon 9 already beats the shuttle in everything but raw payload capacity. Hell, so did the Soyuz.

[–] MTK@lemmy.world 0 points 4 days ago (1 children)

Falcon 9 is only partially reusable, it is not a reusable vehicle, only the booster. Can't really compare it to the space shuttle.

[–] remon@ani.social 3 points 4 days ago* (last edited 4 days ago)

Neither was the space shuttle, so they are totally comparable

And even the reusable parts if the shuttle needed extensive and lengthy maintenance to fly again, something the falcon 9 has vastly improved upon.

[–] phoenixz@lemmy.ca 3 points 5 days ago

Oh come on, stop bashing SpaceX. They've been quite successful at roasting a banana over the Indian ocean, how many companies can make that claim?

[–] simsalabim@lemmy.world 4 points 5 days ago (1 children)

Really expensive to get fuel there on a regular schedule

[–] winkerjadams@lemmy.dbzer0.com 3 points 4 days ago (1 children)

Ok but do we go to the moon on a regular schedule or have any reason to?

[–] jet@hackertalks.com 4 points 4 days ago

Science, research, observations, intelligence, etc.

[–] lostoncalantha@lemmy.world 3 points 4 days ago

No honey the US is falling apart but it is nice to have dreams.

Isn't it illegal to transport fissile material into space?

[–] cubism_pitta@lemmy.world 13 points 5 days ago (2 children)

Illegal may be the incorrect way to say it

There are international treaties agreeing that countries will not do that

Voyager 1 used Nuclear power I believe

[–] flandish@lemmy.world 9 points 5 days ago (1 children)

*used. it is still going. :)

[–] cubism_pitta@lemmy.world 4 points 5 days ago (1 children)

\m/ \m/

You are correct Voyager is metal

[–] shalafi@lemmy.world 1 points 5 days ago (1 children)

I was a small child when it launched. Also, say the invention of heavy metal. Looks like both will outlast me.

[–] piccolo@sh.itjust.works 5 points 5 days ago

Many space probes and landers/rovers used RTGs. The treaty doesnt forbid nuclear fuel in space, only weapons of mass destruction.

[–] Canconda@lemmy.ca 10 points 5 days ago* (last edited 5 days ago) (1 children)

Pretty much every inter planetary satellite has a reactor for power. Not all reactive material is considered fissile.

This is changing as solar panels get lighter and more efficient. Galileo studied Jupiter in the 90s and was powered by an RTG, but Juno and Europa Clipper are both using solar panels to study the same body.
