> The machine also automatically outputs a report that details any deviations during printing, removing the need for postfabrication qualification.

Anyone who's previously worked with 3D printing knows that this simply does not pass any kind of a sniff test. Both preventing and detecting internal defects is one of the, if not the hardest problem in 3D printing. There are many large companies trying to find ways to reliably solve just this problem alone. Saying that this method doesn't require any checks after production is simply false.

They may be skipping small portions of the post-print qual. Or more likely, they're just more confident that the pieces being created are of a certain level of quality. It's a hype-y statement but they're probably trying to highlight that they're doing some sort of software-defined quals.

Finally someone is saying it like it is. Sadly this someone isn’t a bigwig at NASA. NASA still can’t take humans to/from orbit on its own. To believe that in 18 months we’re going to have a successful lunar landing is batshit grade insanity.
LargeTomato · 2 years ago
I don't think you're reasoning is actually sound here.

Nasa doesn't have the capability today, but that does not mean that the capabilities that they are building for tomorrow are "batshit Insanity". This is a very silly take.

We are going to The moon for two reasons. First, we want to set up a more permanent base. Nasa refers to this as "we're here to stay"

The second reason we are going to the moon so that we can put the first person of color and the first woman on the moon. That is explicitly an Artemis mission purpose.

Only time will tell if either of these two missions were actually worth it.

One more point

> Early on, SLS designers made the catastrophic decision to reuse Shuttle hardware, which is like using Fabergé eggs to save money on an omelette.

SLS designers did not make the decision to use shuttle hardware per se. SLS was explicitly designed and funded to use that hardware. One of the original purposes of Artemis, before the other two purposes that we see in the media were even decided upon, was to make use of shuttle hardware.

It's a great accomplishment, but it must also be stated that the FRP isn't for Block 4 F-35s, and multiple DoD staff have gone on the record that Block 4 will be a minimum for survivability, to clarify, that's "survivability" in high-threat environments.

War thinky types divide the "battle space" into zones of danger, and stealth platforms justify their cost by being able to penetrate highest threat areas. It's an idea that hasn't really been tested yet, not really, not since 1993. Hopefully we never find out.

Some of the Block 4 mods have been moved up, particularly the necessary avionics stuff, but some of the mods need rework for heat management and other deeper requirements.

The idea of stealth is tested every day. When missions are planned the capability of the aircraft determines what missions is can fly. A stealth aircraft can factually fly closer to an enemy's AA system without being detected.

It's bizarre that this type of information is made publicly available due to freedom of information legislation. What is the benefit? Or is it merely an acceptable side effect of the greater good that FoIA delivers?

Not that my curiosity isn't triggered, but...

We want to make sure people believe in the deterrent. If people start to think they could take out all of our nukes somehow that would be dangerous.

In America “root” means “barrack” so probably the translation pun you were thinking of wasn’t intended.
LargeTomato · 2 years ago
"Root for" someone means to cheer for someone or look forward to someone's success. You root for sports teams, your kid to do well on their test, or for your candidate to win an election.

Barrack in British English can mean to jeer or boo someone. That's the opposite of root. I've never heard the word barrack used like this in America.

brrrrrm · 2 years ago
whoa, lots of negative reactions to a pretty mundane comment I made about the science of it all. It's overwhelmingly likely, from other studies, that brains differ, sure. But, the AI derived signal mentioned in this study might not be picking up on that? In fact, it's hard to conclude as such from the experiment run simply because it was run on adults. Run it on infants to control for that confounding factor.

It kind of seems like you are being unscientific and politically motivated.

I thought Relativity Space pulled back on their use of 3D printing for the major fuselage parts, saving it more for the engine components, etc., which SpaceX was already doing.
LargeTomato · 2 years ago
I believe you are correct. Relativity is now only printing engines, just like SpaceX, Rocket Lab, Astra, Firefly, Stoke, and others. They are no longer a company driving forward 3D printing technology and that's too bad.

>> for some - most really - the real possibility of death and real consequences is what was necessary to pull out of it

This is not true at all for some significant part of this demographic.

And I feel compelled to mention that I am well-aware that this is totally counter-intuitive.

Consequences for my own inaction play an incredibly important motivational role for me. I don't get motivated by sunshine and rainbows, I personally get motivated by consequences.

So it's great that we can provide people 6 doses of narcan and act like they're big strong adults who are down on their luck, but it's incredibly harmful to pretend that this is the only possible solution to motivating behavior.

Russia's military technology playbook is to exaggerate and disinform claims about capabilities. I'm left wondering if this just DC Russophobia hype being parroted by mainstream media lacking credible intelligence that problematic military space weaponry will be deployed. Congrats CNN, you're doing the work of the Kremlin for them.
LargeTomato · 2 years ago
It's not very far fetched to detonate a nuke in space. The Russians can already do this without developing a brand new weapons platform.

The idea has been around a long time. This was the plot of CoD MW2 If someone nuked above the US and knocked out our grid it would be the most cost effective attack you can possibly think of.
