A community for your defence shitposting needs

Rules

1. Be niceDo not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.

8. Source artwork

If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

They would have to adjust really quickly to track

[–] Dr_Satan@lemm.ee 5 points 9 months ago (1 children)

But really tiny adjustments, because it's far away.

Also there's a spread in the beam, so that's nice.

Also, as I pointed out elsewhere here, there's a vacuum-bottle effect. You can just pump heat into it. And also you don't need to melt it, just overheat the electronics.

You need to move the point from one horizon to the other. Like the sun, satellites "rise" on one side and set on the other. All of that in less than 15min(in LEO).

You can watch the dishes turn.

That depends on its orbit. If you're pumping enough heat into the satellite, you can just aim it at a point in its path. Because space is a good insulator, it wouldn't lose that much heat each orbit.

The movement would need to be incredibly precise.

[–] mindbleach@sh.itjust.works 2 points 9 months ago (1 children)

If the beam is powerful enough, you'd just aim beforehand and let the satellite slide into it. Not like the fucker can dodge.

Honestly the control electronics are not why this super doesn't work.

[–] pearsaltchocolatebar@discuss.online 4 points 9 months ago (1 children)

Yeah, you just need a bunch of geared stepper motors and a big computer. The atmosphere is the reason it almost certainly won't work

[–] mindbleach@sh.itjust.works 2 points 9 months ago

Could do it by hand, if you're patient enough. Again: not like the satellite has much say in the matter. It's gonna be at a specific point, at a specific time. You don't even need to cover the mirrors, since the sun won't be at the right angle for all of them to converge until that intended moment.
