> a whopping 728 feet across, more than twice the length of an American football field
For the rest of the world, this is ~222 meters, more than twice the length of a 100 meter track.

It’s so big we can see it with a telescope, and so small that the chance of something similar hitting any single spot on the surface minuscule in the next 100 years.

But the rate for milligram sized particles hitting a 100m x 100m patch is 2-3 per month.
At 20km/s, that's plenty big enough to ruin your day.

Put a chewing gum in it, push a coin or credit card atop it, for a fast fix. Use Fantastic Fast Foam by Lunar Meta Materials for more permanent repair.

Basically, moon bases need to be underground to prevent micrometeoroids from messing them up, and any bigger impact like this is going to wipe out anything we build, even underground.
All the more reason Earth is pretty awesome!
Fun fact: moon regolith is made of ~45% oxygen, so in a roundabout way digging underground is kind of like having an atmosphere.

or just build it on the earth facing side of the moon , then you have the entire thickness of the moon shielding you. But I believe some of the more interesting use cases for lunar bases require the far side, notably telescopes
Edit: this is incorrect, see below
teraflop 1 days ago [-]
The lunar near side is not shielded from impact craters in any significant way. Impactors can cross the earth's orbit and hit the near side of the moon just as easily as they can hit the far side.
The fact that the near side appears to have large areas with few craters, and the far side doesn't, is a result of many near-side craters having been erased by lava flows. It's not because it received fewer impacts.
jedbrooke 24 hours ago [-]
Interesting, I did a quick search and you are right. I think I remembered the incorrect fact about the near side being shielded from 2001: A space Odyssey (the book). It actually has a few other outdated moon facts since it was written just before the Apollo missions

Popular myth. "While the Moon does undeniably experience asteroid impacts, these impacts do not proportionally alleviate the impact risk to Earth; instead, both celestial bodies are subject to independent and interconnected bombardment" [1].

I like your reasoning about oxygen and would like to contribute the factoid that the molecular weight of CO₂ is over 72% oxygen. We really need to be spewing more of this stuff into the atmosphere to improve its oxygenation. Obviously O₂ would be best, but CO₂ is much more practical, and still gets us 72%.
I don't even get that far but get a blank page except for: "Please enable JS and disable any ad blocker." They're doing a pretty good job of minimizing their traffic.

New York Times 10-Year Online Subscriber Growth
• 2016: Ended with approximately 1.6 million paid digital-only subscriptions.
• 2018: Crossed the 3.3 million digital subscriber mark.
• 2020: Accelerated past 5 million digital subscribers, fueled by intense news cycles (the U.S. election and COVID-19 pandemic).
• 2022: Surpassed 8.8 million total subscribers after shifting reporting metrics from individual product subscriptions to total unique subscribers and acquiring The Athletic.
• 2024: Reached over 10.8 million total subscribers by year-end.
• 2025: Closed the year with 12.78 million total subscribers, adding 1.4 million net digital subscribers over the 12-month period.
• Mid-2026: Reached 13.35 million total subscribers (including ~12.8 million digital-only subscribers), staying on track for a stated goal of 15 million subscribers by the end of 2027
That didn't pass the sniff test for me, and yeah it's misleading. Not on your part, but theirs - probably to try to appeal to advertisers. See the fine print on their numbers here. [1] Rather than copy-paste a bunch of stuff ctrl+f there for "The Company includes our digital and print products and related businesses, including:". Those numbers are an opaquely combined total across a whole slew of different services, brands, companies, and promotions. Suffice to say they're certainly calculating it in the way that will yield the largest number that's legally defensible.

In some more enlightened timeline there's a spirited competition between institutional and amateur astronomers towards predicting these, and some amateur is sitting on a $10M this-person-told-us-so-and-we-bet-against-them prize, which gets bigger every year (no prizes for the institutional side, they get a salary).
In that timeline's future we're then competing over who can most reliably prevent them.
The winners of such frivolous competitions over protecting the moon get funding for the more serious job of protecting Earth.

You could create a lunar grid on a betting market with yes/no contracts for impacts above a certain threshold.

The article says a new crater this size is expected about once every 132 years. Presumably, smaller craters are more frequent. So what's the approximate size of the largest crater that you'd expect, say, in an average year? And would it be scientifically useful to design a mission around sending a rover to explore one of those brand-new craters?
devsda 1 days ago [-]
> The impactor would have caused a luminous explosion comparable to one made by 15,500 tons of TNT.
The crater is small enough that it is probably not obvious to spot visually.
But I'm surprised that we missed noticing an impact event of that size when it happened, or even the space object that caused it.

As with Mars (and Silo) we need a very deep pit to protect humans from the radiation.

Just build right there in that crater. Like lightning, a meteor rarely strikes the same place twice. It's a statistical law, independent random events be damned! :)

Does anyone really want to live on the moon? I mean it's a cool and dreamy idea but would you actually do it?
hackeraccount 9 hours ago [-]
I'll be dead before it's possible but heck yeah. I'd miss going outside. I suspect there'd be annoying compromises on the atmosphere inside the habitat (presumably it'd be like living inside an airliner in that regard).
On the plus side though - what if they have swimming pools? Swimming around in less then 1G. I would definitely at least visit if they had that.

Life on the moon is likely to develop in much the same way that humans settled in far-flung places on Earth. The first people to arrive and live on the moon will be there for a work-related reason (research, military posting, etc.). Those people will settle down, have families and form a community. Over time, the communities will grow and evolve into a distinct Moon culture and society.

Why hasn't that happened in Antarctica?
accrual 1 days ago [-]
I feel it has in the sense there is an established culture in some major Antarctic research bases. There are stories, communities, and shared history. But most of those on the ice come home after a season or two, so there's no long term settlement of individual families. Maybe this would also be true of moon bases. Researchers stay for some time, then take the next available ferry home once their season lapses. There would have to be significant infrastructure to make "ordinary" life possible over the long term - schools, hospitals, non-research jobs - reasons for staying there versus migrating back to Earth.
FWIW, there's a nice series of posts about life on the ice here: https://brr.fyi/

It is, it's just happening slowly. We went from having a campsite to building a permanent base. Food water and energy sustainability are the major barriers right now. Once the base can produce its own food reliably, we will see people start to live there persistently.
