They had to build a really tall ladder to get this view. Quite the project.

The nasa blog on the final day said. “At 5,400 feet, Orion’s drogue parachutes were cut and the three main parachutes deployed, reducing velocity to less than 200 feet per second and guiding Orion on its final descent and splashdown.”

Which is to say “less than” roughly 60 meters per second. Somewhere else on the site I couldn’t find again they mentioned it being a touch down speed of 20 miles per hour, which is a fair bit slower at about 9 meters a second, but that’s still a car crash if you’re hitting a solid surface.

The point remains. Getting a large object like that down to a soft, non injurious, speed is not practical with just a parachute. Other techniques must be employed.

So, the issue does come down to the chutes. A chute capable of reducing decent speed to 10m/s is significantly larger than one capable of getting the speed to 60 m/s. Impractically large on a weight constrained thing like a space capsule.

The Soyuz uses a small set of retro rockets to reduce speed in the last few seconds before touch down, and even then it’s like being in a car crash.

On the Vostok capsules the astronauts didn’t even land with the capsules, they just bailed out and parachuted down.

Landing in the ocean is significantly more comfortable and less complicated.

Artificial carbon removal was never invested in because it was a good solution, it was invested in because it was an easy excuse. “We’re developing the technology to remove carbon, so no need to stop emitting it”.

It was about putting out headlines and creating a narrative that diffused public outcry. Enough people are now aware it’s infeasible at scale that it’s no longer useful as an excuse. So the investment is disappearing.

So currently, the draft system is not legally provisioned for in the US. It would require a law to be passed to reinstate a draft.

Right now there is just a list system for if that were to happen. This change is just making it so people are automatically put in to that list system, as supposed to having to manually do it them selves, arguably a good thing since it was already mandatory. Not registering for the selective service is a federal crime, and a lot of people have failed to register because they don’t know or simply forgot to.

It would probably be better to remove the selective service system all together, make it harder to reinstate a draft in the future. But if it is going to stick around and continue to be mandatory, it’s better it be an automatic system.

In general, there are basically no federal level “lists of all citizens”. The closest would be social security (national pension fund and elderly health insurance system) but even that doesn’t really work for identifying people or tracking them. it’s something people in the US have been very paranoid about for a long time.

As depressing as it may be, I think his base cares more about filling up their pavement princess pickups than they do about the Epstein files. So that seems like a really stupid move from him in such a case.

[–] megopie@beehaw.org 5 points 1 week ago (4 children)

Lmao, the dumbest fucking move he could have made.

Like, if he had just quietly backed away and pretended like everything was fine, let Iran charge tolls for passing through the straight as an implicit form of reparations that the rest of the world would pay for. Gas prices would have have come down, and his own base would have forgotten the whole thing.

But nah, he’s going to force gas prices to go up so long as he doesn’t get… what? What does he even want at this point? What is this even about?

Can’t wait for Schleswig-Holstein and France to fight distro proxy wars.

This was legitimately a significant concern that early space programs had. Like, how well would people be able to swallow in free fall, would certain kinds of food cause problems? The food experiments during the Gemini program are pretty interesting

See the trick is you gotta combine that with eating more fiber!

Then your will piss more and you will poop better.

[–] megopie@beehaw.org 1 points 2 weeks ago

Yes, but consider that if there is bark, cinnamon is bark.

[–] megopie@beehaw.org 2 points 2 weeks ago (2 children)

So… are they spices? Like cinnamon?

 

I’m aware of things like framework and they’re a cool system, but they’re limited in what chipsets can be used by the mother boards they offer.

I’m thinking in the context of a cheap low spec system that can be handed out for use by a group. Most of the options available are just very pricy.

Maybe something like a SBC would be a better fit since there are plenty of cheap options out there and they can be mounted in a custom built shell with the other needed elements.

A thought that crossed my mind was ordering printed circuit board and just soldering on the sockets and the like, but that’s a very involved process with a lot that could go wrong. Especially for someone with very little experience.

Short of custom ordering from a company that does such things, are there any systems for building a mother board?

This is more out of curiosity about what options there are out there. Any other thoughts people have about custom built laptops or interesting things in that space?

 

I’m looking at various single board computers ( think raspberry pi) to host a server on. Namely for hosting media, an email, and perhaps a web site/fediverse instance/blog/forum on.

I’m under an assumption that a SBC and some hard drives could handle this on the hardware side. Am I totally off the mark? And what kind of os and other soft wear should I consider using?
