Are rescue spacesuits useless?

[Jacke]

Since we're talking about SpaceX suits, how about something I noticed back at DM-2 launch: those all-black suits the pad crew wear.

Consider one of the greatest threats is a pad fire.  I don't know what those suits are made from, it could be fire resistant.  But unlike naval anti-flash gear....

...the SpaceX pad crew are in all-black outfits that will get hotter faster in a fire.

Along the same lines, while white makes sense for EVA suits, orange or some other  florescent color would have made a lot more sense for flight suits to aid search and rescue.

I don't see why you couldn't make a suit with both biological and other things to generate air and other resources. Start with poop from the person. Maybe even poop from the ship itself for added help. Then maybe pre setup it and plants or something similar and have a speciality suit for long rescues. Some things could be done ahead of time put in the suit other things could be done along the way to expand it's use and recycle things in the suit.

it's crappy, but you would survive. I think astronauts area already used to that sort of thing to start with. The systems could be improved over time to make them less nasty.

It could even try to recycle food and basic nutrients for the host.

Day five journal: I'm still waiting to be picked. It's been another long crappy day. The tang is starting to become very diluted.

I'd imagine it wouldn't be fundamentally hard to make a green house with the visor, have some bacteria or none growing plants in dirt or packages to be released inside a dirt containment area for fungi or something and eat mushrooms and other things in dirt and recycle pee and flavor it with tang or other dried astronaut foods. Mushrooms literally grow daily and predictably. Not sure on the nutrients though. Just need a simple efficient oxygen scrubber and recycling plant. It could be high or low light. But you might need both incase of shadows. And maybe artificial lights for the same reason. There are very low light plants and bacteria like things you could put in water or dirt for varying circumstances. Account for cold or other things also somehow. can you use a peltier or other things to convert heat or generate enough for minimal temps? Or even a psuedo cryo sleep. Either for longer periods or more realistically just for nights or dark periods behind planets. wake up eat and poop and drink etc. Wait for, "night," etc.

Required compact nuclear source of energy would make food prducing unnecessary.

He would have neither time, nor desire to eat.
