It's always good to find problems in the safest way possible, but wow these guys need a win right now. Hope they move forward quickly and safely.

Longest stay on the moon was 75 hours, anybody know if they mentioned their sinus clearing during that time?

>with blood and fluids not being pulled down by gravity, your head tends to be more full of fluids than normal, and it feels like a mild cold congestion all the time.
I'd be interested in knowing what is the minimum G you need to avoid this. Creating 1G in space via spinning is very problematic, but making .05G would be easy. Would it help?

In Canada our antiseptic mouthwashes are usually tinted green, while our peroxide rinse mouthwashes are usually tinted blue. Peroxide tastes terrible. Hope this isn't that.

When you cut through a knot while turning a log into lumber, the resulting mark is sometimes called an eye. I've never heard it applied to a live tree though.

In many countries knots are also known as eyes, but usually after they're cut into lumber.

Damnit. I might get laid off next week. Might have to use the spare time to confirm that hypothesis.

Yeah, "40 million times greater than a bowl of rice crispies" isn't helpful OR scientifically accurate.
I mean come on, everyone knows skim milk makes them louder.

Reply to comment by PyroDesu in Was reading something related to Rock Salt mining. In places like the Himalayas where rock salt mining is done in cold temperatures, a lot of miners report burns. Why is it so that salt burns in a colder surroundings? Would it be the same reason why the salt ice challenge was so dangerous? by vvdmoneymuttornot
Mostly true, but there are wet mines. My company used to have one on the East Coast of Canada that literally went out underneath the Atlantic Ocean. They were under the ocean!
The rock was very cool, so all humidity coming in on the fresh air formed as condensation on the walls, creating a wet mine.

Canadian Potash (potassium chloride instead of sodium chloride) mine here. Our mine is roughly 76% NaCl and 22% KCl. What we mine is then refined. Our mine is dry, so I've never experienced salt burns, but if you have other questions I'd be happy to answer them.

Reply to comment by spiralbatross in Scientists Successfully Split Seawater To Produce Green Hydrogen by __The__Anomaly__
Lol, do a little Google search for something called a potash tailing pile. Gigatons of free salt, usually a little contamination of potassium, clay, various carnalites, and sometimes some chemicals from the milling process, but still about 98% salt.
The problem is that salt is so INCREDIBLY cheap, it's not worth refining to get that 2% contamination out. It's usually cheaper to mine it in a more pure form, and then ship it a thousand kilometers to where it needs to be sold.

In this case they've literally spent the last TWO decades working on this, and still have yet to even try, so yeah I'd say that's worse when they're applying for contracts.

I'm still highly skeptical that an engine with that large of a chamber and that high of a chamber pressure can survive, but I guess we'll see!

I think SpaceX has lots of time to get that working, since Artemis is insanely behind schedule anyway.
Further, that's a different kind of contract. NASA is paying to have something built that has never been done before. If SpaceX doesn't hit milestones in that contract, they don't get paid. They both know that.
Even further, SpaceX underbid that contract to win it. They're using some of their own money to build it, knowing they will use the tech themselves down the road.

It's even worse than that, not only have they not gotten to orbit, they've never even tried to get to orbit. They've never built anything that was even capable of trying for orbit, and right now they don't have anything that launches at all.

I still remember the first time I woke up with that, I was about 12 or 13 I think, and I freaked out so bad because I thought my arm had been paralyzed. It was such a weird feeling having a dead limb just hang, no sensation, it was like an extra piece of meat just hanging from my shoulder.
