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.
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.
Yes, but consider that if there is bark, cinnamon is bark.
So… are they spices? Like cinnamon?

I mean, it… does expand when freezing… so maybe?
Probably not, ammonia production isn’t exactly a huge portion of natural gas usage, it’ll just have to compete on price with other demands, other things with lower value will get priced out of the market long before nitrogen fertilizer. The price for it will probably go up, already has on futures markets, but not by a huge amount, not even the biggest blip in the past decade. And nitrogen fertilizer is a fairly small portion of overall costs for most agriculture, so it won’t be a significant increase in price.
The places it might have an impact are on products with really narrow profit margins already, like commodity corn in the US (actually a lot of commodity corn breaks even or even is grown at a slight loss because reasons ) and a lot of that goes in to non-food uses like ethanol(for gas), chemical production, or even for use in construction materials.
And then you have E bike companies producing lead bricks that are non-functional without the motor doing 90% of the work. Or with the massive motorcycle seats that make pedaling actually impossible.
In the us, there was a dark and dismal corner of poltical science called Kremlinology, where far to much attention was payed to the positions various people were during speeches and parades, trying to determine who was and was not influential with in party at any given time, and then try to determine Soviet policy and action based on this.
Having access to the archives, we now know that they were almost entirely wrong, and the times when they were right were basically just random chance.
Like, it was ancient divination more than it was real analysis. People called them out on it at the time, but, they were influential because the CIA was gullible and congress was desperate for any sort of insight.
