I was going to say the same. They did follow up with “However, we would appreciate your sense of humor in chat if you want to drop by!” but the bolded comment above significantly outweighs this.

At least this earlier comment was deemed relevant and not too jokey:

> Even more fun, Apollo 14 didn't use their grenades, and they are still on the lunar surface.

This was a solved problem by Slashdot decades ago: You introduce a simple tagging system: "Insightful", "informative", "funny", etc. then you let the community tag comments accordingly. Then if you want to filter out jokes, or only see them, you can do so via a simple UI switch.

[−]shevy-java · 2026-11-15 Sun 12:09 UTC · link
On reddit there was a ton of censorship.

I dislike censorship in general. Someone else decides whether I may read comment xyz from another human being (assuming it is a human being). I don't want censor-in-the-middle people, be it on HN or reddit. Old reddit was easier to use than HN though; on HN we get time-locked as well as jokes-eliminated. That forces a more serious tone. I do not think it really improves the signal to noise ratio though; usually it means that there are fewer comments in general, including potentially interesting comments. I mean, if HN were serious about joke-censorship, any funny story shared by someone else on HN, even if historically accurate, would also have to be censored. After all you can not evaluate whether a claimed story to be true, to NOT be a "joke in disguise". I could go on and on here, but at the end of the day it just boils down as to whether people like censorship or not. You may reason that you prefer it, to "pre-filter away content you never want to read", such as a joke, but for me, I just dislike that someone else sits in the driver seat and tells me what I am allowed to read and what not. I want to decide on that on my own and I have no issue with "noise ratio"; I don't read all comments anyway, simply due to lack of time. I can only glimpse at some of them. Do you really have the time to go through all comments on each entry on HN?

[−]Sharlin · 2026-11-15 Sun 12:31 UTC · link
I dislike (nay, find absurd) the idea that private people should provide for free a platform for random people that they’re not allowed to moderate because "censorship" and "free speech". Also, Reddit is probably the least censored mainstream discussion platform on the open internet, even after expelling all kinds of terrible people.
[−]SV_BubbleTime · 2026-11-15 Sun 16:14 UTC · link

Absolutely not.

There are instant banned topics on Reddit. AI banned topics site wide. Go write something like “the USA imported the third world” and enjoy your instant 3-day ban.

Nicely editorialised there, skipping the second half:

On HN many purely jokey comments are often discouraged, being down-voted and getting replies along the lines of "this isn't Reddit". Is HN dying, by the same measure?

[−]saaaaaam · 2026-11-15 Sun 12:03 UTC · link
I think there’s a distinct difference between a community collectively deprecating something, versus individual members of a community deciding what will and will not be deleted. The first means the comments just fall away, while the second (and a statement of “we will delete your content it is not welcome here”) is actively off-putting not only to those who post that sort of content but others passing by who may be put off posting anything in case they unknowingly “break the rules”.
[−]dspillett · 2026-11-15 Sun 12:56 UTC · link
I don't see a problem there. “I won't post a jokey comment here as it'll just be deleted” is the system working. Much better than what has become the norm elsewhere: “delete if not allowed” which more-often-than-not means “I know this is not what is wanted here, but screw you and your rules”. They have explicitly stated that such content is welcome, just a little further away from the business end.

Probably was both. NASA got a COTS component for their seismologic experiment, saving some time/budget on R&D, and military got to have a grenade launcher tested on the Moon, providing data for whatever "future warfare" programs they were surely running back then.

This year bear encounters made headlines in Russia, but the number of fatalities isn't unusual. Records is 80/year in 1985, 1986 and 1996. Brown bears don't see us as food as long as there is some other food available. If food is scarce this year (some random dude on the internet says that there were an early thaw followed by freeze in 2024 that cause pine cone yield in 2026 to fail) they might attack. Either out of desperation or when encountered over a food source (i. e. garbage dump) and mistakes a human for a competitor.

[−]fhdkweig · 2026-11-15 Sun 17:24 UTC · link
It may be invented, but not by him. It is at least as old as the 1997 film Contact.

https://vimeo.com/188517388

The description blurb reads:

  "Since Apollo 13 many people have asked me, 'Did you have suicide pills on board?' We didn't, and I never heard of such a thing in the eleven years I spent as an astronaut and NASA executive," - Jim Lovell, commander of the ill-fated Apollo 13 mission.

  For this scene, from the movie "Contact", based off his book, I guess Carl Sagan got inspiration from the Soviet Voskhod 2 mission. Cosmonaut Alexey Leonov said he was given a suicide pill by the authorities, in the event that he might get stuck outside of the Voskhod spacecraft while attempting the very first "spacewalk" or EVA (extra-vehicular activity).

  For NASA's options, Gerry Griffin, a former director of the Johnson Space Center in Houston, Texas, corroborated Lovell's statement, bluntly adding that if an astronaut truly wished to end his or her life, space provides plenty of opportunities. Outer space is just as effective a suicide agent as a cyanide capsule, perhaps even more so. Exposure to its empty vacuum often results in a blissful loss of consciousness in a matter of seconds. Death by asphyxiation usually follows within two minutes. (from http://www.realclearscience.com/blog/2013/10/astronauts-and-suicide-pills.html)

  Uploaded on Oct 23, 2016 at 5:36 am
As for the 2013 link, it reads that although the Americans weren't issued suicide capsules, at least one Soviet had one (although he didn't say if it was issued by the space program vs him just carrying it with him of his own accord).
[−]dylan604 · 2026-11-15 Sun 17:59 UTC · link
And how would that suicide pill work exactly? It's not like they could reach into their pocket and pop it in their mouth. That means it has to be in the suit and specifically in the helmet. Again, how would that work? Where's the pill located so that it is accessible in the helmet? Did they replace a tooth so they could just bite down really hard like other nonsense spy movies? So much of this doesn't track
[−]echoangle · 2026-11-15 Sun 18:45 UTC · link
> It's not like they could reach into their pocket and pop it in their mouth.

Why not? I think the failure youre defending against is "Retrorockets have failed but the capsule is still pressurized", so you could easily just take the pill and have a nicer death than suffocating.

They already had a makarov pistol with them from the start. They made this custom short barrel double shotgun with a third rifle barrel.

This was to fend off wild life and maybe hunting while waiting for the recovery team to get to them if they came down far from the designated recovery zone.

"The mortar package is activated by the "arm grenades" and "fire grenades" commands from Earth. The arm grenades command is applied to and gated through the command gating to the grenade arming circuitwhich charges the regulaz and sequential firing capacitors of the four grenades by applying a Z4-volt arming signal. A grenade arm pulse is also applied to the data handling function indicating receipt of the command."

OCR is letting you down a little bit here. Neat that you found this though!

To gun down the aliens. The answer is so obvious.

First thought: were these fragmentation grenades? Second though: nope: not useful for seismic research. Third though: on the moon, thrown fragmentation grenades wouldn't be safe for the thrower.

Without fragmentation, isn't it just going to fly off in one direction with very little damage in any other direction?

All grenades have a casing the "fragments" when they go off, but some use thicker, heavier, scored metal casings to maximize the anti-personel effects of the resulting shrapnel. If you don't want shrapnel, then you make the casing light and arrange for it to break into fewer pieces. So grenades designed to produce more, heavier, sharper fragments are called fragmentation grenades.

Michael Bay added it so that the official Apollo Mission action figures would sell better.[1]

Like it was just a default for the game engine they were using.

The question is pretty unnecessary given that it references the "ALSEP Flight System Familiarization Manual" [1] which also goes into detail about the purpose of the grenade launcher.

Closed as duplicate. Your question is bad and you should feel bad.

Why does this site need to share my precise geolocation with 263 partners? It's madness.

Went down a rabbit hole to see if the Apollo "thumpers" were named so because of Dune. Apparently there were a few terrestrial thumpers in use by oil and gas surveyors prior to the book and missions... whomp whomp.

Does anyone know why they had the grenade launcher? stackexchange decided a few false positives humans getting blocked was okay if they could mitigate the corporate bots and block most of them. The end result is that I can't read the page.

From November 2 to Nov 22 2018 the "DrSheldon" account asks exactly one question per day. https://space.stackexchange.com/users/drsheldon?tab=question...

Like this one, most of the questions are worded to enable an easy answer from a primary source.

In one instance the account answers its own question within the same minute: https://space.stackexchange.com/questions/31279/how-was-the-...

In another instance, the account replies to a comment with "Nonetheless, this would be the question to document any examples."

Remember the guy that was hyper active wrt C# questions maybe 10 years ago?

People were amazed he would answer every C# and WPF questions minutes after they were posted.

I am convinced to this day he did the same thing.
