2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.

If your flight is on a Boeing aircraft, you’re likely in the same situation as the astronauts.
What I can’t understand about this situation, is they’ve apparently been studying the craft’s helium leaks this whole time. But, as far as I’m aware, they’ve done 1 EVA to look at the thing. How are they inspecting the physical condition of hardware(pipes, seals, welds, brazed joints) via software from the ground and the results of one EVA. I also can’t see NASA giving the green light to really strip the Starliner to the guts while it’s attached to the space station, so did the astronauts even get a chance to look closely to find these leaks. A quarter of my job is finding leaks in high pressure piping systems, and you often have to really get in there and remove all the panels to pinpoint a leak. I highly doubt nasa has allowed the crew to rip apart a space capsule the same way I would rip apart a rooftop unit.
The thing that takes the most time isn't looking at the thing, it's doing the engineering to figure out WTF you're going to do about it afterward.
Well, there are a whole lot of sensors and monitors on all of the hardware in that capsule, and all that data gets collected. So they can tell a lot about what's going on with the capsule even remotely. But it's still a lot of data to dig through and analyze.
And then once you identify the problem it's like... "well the temperature on component X went way past its lower limit and one section of the fuel line went way over pressure and this third sensor isn't responding at all", so... now you know some things, but that might not immediately tell you what exactly happened, or why it happened. And then once you figure out why it all happened, there's trying to figure out how to prevent it reliably without introducing new problems.
And I think you're right that it is actually pretty hard for the engineers to do all that without physically being there. I wouldn't be surprised if a lot of the slowdown is due to needing to replicate the problem in simulations or physical mockups down on earth.
Don't think so.
They do have access to camera imagery, but as you say, most problems like this probably need much more intrusive investigation.
