Right now there are many people struggling on Earth to get clean drinking water, so water scarcity is a real world thing that certainly wouldn't be any better for spacefarers.
One problem with water that is on the Earth is that it's very expensive to send it into space. That's analogous to the problem of moving water around on the Earth. Sure there's plenty ...
How was that scene filmed?
Wirework and CGI for the hair.
Syfy has an "Inside The Expanse" series of 'behind the scenes' videos.
In the case of this specific scene, it's shown at the very beginning of the first instalment.
These are also on Youtube.
It has been captured under the "law of salvage":
This has been addressed in the show and in the books - by the law of salvage, whoever claims abandoned vessel in space has the right to keep it. Of course, Mars wasn't too happy about it, but it cannot act with force, as this will further destabilise the political situation within the system.
In the book ...
... and that Naomi secretly gave Fred the location of the hidden proto-molecule torpedo?
Exactly this has not yet happened at the moment of the Fred-Holden conversation (S02E08); only in a later episode does Naomi give away the location of the protomolecule sample. And the protomolecule is indeed the motivation behind Fred's "hostility": Holden is heading ...
If you have only watched the first (few) episode(s), I suggest you don't read this answer and watch the rest of the episodes.
I don't quite understand the premise of the question. Private military contractors and mercenaries (so-called "soldiers of fortune") have existed for a considerable amount of time in real life. Why do people become a mercenary and ...
From the second book, Caliban's War, Chapter 48:
“Okay,” Holden said. “That was bad.”
“What?” Avasarala said. “What was bad?”
“One of the Earth ships just took three torpedo hits.”
“It that a lot?”
“The PDCs (Point Defense Cannons) aren’t stopping them,” Naomi said. “Those UN torpedoes all have transponder codes that mark them as ...
Martians are known for their excellence in science and research (stealth ships, the best navy, etc). Why wouldn't they use their own private companies, or perhaps government organisations
It is unclear exactly how much the MCR outsources on a daily basis. Just because MCR has state-of-the-art technology does not inherently prove that they made it all from ...
My guess is that Jane himself is driving his character's look, possibly as a fan of the artists I mentioned, facilitated by wardrobe and makeup people with an appreciation of that aesthetic.
As far as I'm aware, there is no proof of that.
However, there is a tiny bit of supporting evidence that Joe Miller (the character played by Jane) drives his own ...
Something like "retrograde thrust".
You pretty much nailed it there.
It's usually applied to orbital manoeuvres since we currently don't venture out much further than Earth/Lunar orbit
A retrograde orientation is one that has the ship facing in the opposite direction from its direction of travel in its orbit.
A retrograde burn is one in that ...
