Hi!

I have a character in a sci-fi universe who ends up "shipwrecked" alone on a completely uninhabited planet for two years. The planet, and the specific environment he lands in, are perfectly habitable by humans (we are in soft scifi territory here, very Star Trek inspired) and he's able to survive with some effort. (The details of how are not really important to the story - I know at least that he's the kind of guy who'd be able to salvage some tech and emergency supplies from his wrecked ship, and I'm comfortable with brushing past the details of what exactly he brought with him - but if anyone's really interested in coming at it from that logistical angle, I won't stop you!)

What is more relevant to the story is how this experience would continue to affect him by the time he's back home safely. I think there are a bunch of possible avenues here and I'd love to see people's takes on how they would approach this or approach researching it. For example, here are some of my cursory thoughts:

PTSD is certainly a likely long-term complication
It's implied that his shipwrecking was not an accident/was engineered maliciously - I imagine this is something he has dwelt on heavily throughout the two years and will affect his ability to trust people (and to visit other uninhabited planets in the future!). Seems like it would be easy to get caught in delusional spirals in a situation like that.
I know that prolonged isolation can cause hallucination/psychosis in some cases, especially in solitary confinement, sensory deprivation contexts, etc. Is that as much of a risk in this case? And if so, do you think he'd still be experiencing psychotic symptoms after the fact?
One of his personality traits is that he's fairly attention-seeking - I think it's likely this incident will exacerbate that and make him more desperate for connection
It'll probably alter how he approaches social situations in the future in general; that's something I'll definitely be thinking about
Perhaps he got into the habit of talking to himself on the planet, and this never went away

Happy Saturday!

I'm going to be doing a little maintenance today. It will likely cause a tiny interruption of service (specifically for www.dreamwidth.org) on the order of 2-3 minutes while some settings propagate. If you're on a journal page, that should still work throughout!

If it doesn't work, the rollback plan is pretty quick, I'm just toggling a setting on how traffic gets to the site. I'll update this post if something goes wrong, but don't anticipate any interruption to be longer than 10 minutes even in a rollback situation.

For large-scale projects, specifically for ships. All my ship-related resources for the era are for the British Navy, and books on colour that I've read have been on artists' paints or dyes.

How would a French Imperial Navy vessel be painted, not at one of the big shipyards? Would it be mixed up on site from raw ingredients, or bought in? Would there be barrels, buckets with lids, cannisters, vats or what - and what would the paint be made of?

Searching online produces info on painting scale models, or contemporary pictures of ships. I found a chapter on ship decoration in Conway's History of the Ship: The Line of Battle but that doesn't have the early-in-the-process details I want. I found an article on the pre-Revolutionary Navy in the International Journal of Maritime History, by David Plouviez, that's too early and still doesn't cover paint.

Thank-you in advance.

Okay, I thought I knew science, but after several days of researching this, all I've got is indecision and a headache.

Original fiction, unspecified not-too-far-future time.

My character is the pilot of a small cargo ship in the asteroid belt. (No FTL, no artificial gravity.) Said ship has sufficient radiation shielding to be safe under normal conditions. My idea is that there's an unusually strong solar event (solar flare? coronal mass ejection?), and he has to survive by positioning his ship on the shadowed side of an asteroid (rocks are good shielding), and use his excellent piloting skills to stay there until the storm passes.

1. Does this, theoretically, actually work?

2. I'd like the solar event to be a Coronal Mass Ejection, because some CMEs move relatively slowly, and that gives my character time to make a narratively interesting choice. But is it the CME itself that's hazardous to human life, or a sort of "bow wave" of radiation that precedes it? And if the latter, is that radiation moving at the speed of the CME, or the speed of light? (I keep thinking I have a grasp on this, and then the next source I read contradicts it.)

Guidance appreciated, fellow space enthusiasts!

ETA: Okay, based on comments and additional research the comments inspired, my takeaway is: (1) CMEs can happen with or without accompanying radiation, (2) the stuff in the CME itself is not dangerous to humans, (3) the dangerous-to-humans part of the radiation travels at the speed of light. Which means this story is probably dead; I really needed that longer warning time for the narratively-interesting parts, darn it.
