We're omnivores, not herbivores, despite what vegan nuts try to tell people. we are biologically much closer to herbivores than you seem to think.
it would suck compared to the standard american diet of addictive tastiness yeah, but the only nutrient we wouldn't be getting with a purely space plant diet would be vitamin b12, (which is injected into some of your commonly edible animals since they cant get it naturally due to industrial farming limiting their day to day,) and it's more efficient to take a supplement for that anyway regardless of how much meat someone eats.
otherwise prolonged exposure to near zero g environments would be extremely bad. you would not die from any form of malnutrition, but you're right you'd spend a *** of oxygen and calories and time maintaining your bones and muscles in zero G, since everything would start to atrophy the second you left.

Not at all, and prolonged exposure without any sort of artificial environment would require extensive physical therapy if not cause permanent damage.
I'm not saying we shouldn't travel space as we most certainly should, but there are a lot of obstacles in the way. Really as soon as there's money to be made by vast amounts in space, we'll see it happen.

don't forget we've had people go to space for an entire year and just work out a *** to counter the atrophying of their bones and muscles too.
Nasa is working on a few ideas with the radiation problem
Quote: To completely block radiation, hydrogen-rich shields would need to be a couple of meters thick--impractical, because of the weight and volume. But, oddly, 30 to 35 percent of the radiation can be blocked by shields just five to seven centimeters thick. That, suggests Cucinotta, might be the most efficient choice.
Quote: Antioxidants like vitamins C and A can help by sopping up radiation-produced particles before they can do any harm.
Quote: Another researcher is exploring the cell cycle: as a cell divides, it pauses occasionally, to check its genes for any kind of damage and to repair errors. With pharmaceuticals that lengthen this part of the cycle, researchers believe they can give the cell more of a chance to fix its own problems.

If the ship was able to have some artificial gravity then it wouldn't be too bad, otherwise prolonged exposure to near zero g environments would be extremely bad.
Starting to read more of the idea: the whole bunch of plants this is basically not probably viable. Generating enough food for 2 humans to eat healthy for prolonged periods would require a lot of space. Not to mention that people need nutrients that you're supposed to get from animals. We're omnivores, not herbivores, despite what vegan nuts try to tell people.
Tsk those fit and healthy vegans sure dont know better! Here have some delicious tofu <3

There's nothing healthy about being malnourished.

KN, having done high security indoor gardening in the past I can say that plants grow just fine under artifical lighting 1/5 as intensive as sunlight. And I don't doubt that at all. But that goes against Josi's original premise of solar-only setup.
You literally cannot feed plants the further out you go in space, and we are talking about deep-space explorations, not just explorations within our solar system.
Sunlight is way more intense in outer space due to not being filtered through earth's atmosphere. I would guess that at Jupiter's orbit sunlight is less intense than at earth's surface, but not by much. And plants require such filtering too. But even then, they will all die before you even hit Neptune.

It's like sleeping outside in your front yard for a year and then claiming that you are ready to travel outside your state (or in your case, country) by yourself with no human assistance (food, shelter, clothing, or any of the niceties of civilization).

tbh you guys are focusing on light, but really the issue is water. even composting and a filtration system to clean waste you're going to run out of water. growing plants especially on the scale you're talking about is super water intensive. every round of plants/consumption is going to cause some water loss. essentially you'll be able to grow less and less each time. nutrients for feed and light will be the least of your worries.

All of this is pointless conjecture. There's a mass relay just outside of the edges of Sol waiting to be activated so that it can connect us to our very first intersolar war peaceful spreading of freedom, capitalism, and democracy.

We are biologically omnivores, full stop. Any exclusion of food types in our diets is either from environmental circumstances or behavioral choices.

Quote: A new study in the Journal of Geophysical Research: Planets, a publication of the American Geophysical Union, suggests there are between 26 and 80 hydrated near-Earth asteroids larger than a kilometer in diameter. Of those, 8 to 26 of the asteroids are easier to get to than the surface of the Moon. The new study also estimates there are between 350 and 1,050 smaller hydrated objects easier to reach than the Moon.
The study’s authors estimate there are between 400 and 1200 billion kilograms (440 to 1.3 billion U.S. tons) of water that could be extracted from the minerals in these asteroids. In liquid terms, that’s between 400 billion and 1,200 billion liters (100 billion and 400 billion U.S. gallons) of water. That’s enough to fill between 160,000 and 480,000 Olympic-sized swimming pools. plus if we can mine that much water, it means we can turn the excess into oxygen to breathe and hydrogen to power the ship

Star Wars is getting the reviews I expected, and I think it will be a lot worse movie than what they are saying about it. On the plus side, Mandalorian finally got its ***together today.

You hush and what problem have you had with the Mandelorian thus far?

But sure you could use it for propulsion maybe if we still wanted to use combustion propulsion.... though if you have a power source doing all that I'd imagine you'd go for some kind of electromagnetic propulsion

ok. so we're playing full science fiction where we can easily stabilize and mine water off of asteroids and we somehow mastered hydrogen fuel engines which we can't even do on earth. a lot of the water on the asteroids and comets varies wildly from the water on earth. the layers of water on asteroids also is very thin layers of ice surrounding it that would be almost impossible to gather efficiently short bringing the asteroid in side your ship and letting the ice melt and collect on the floor into drains. even then you're dealing with water that has been collecting radiation unfiltered from lack of atmosphere (do you want monster plants, cause that's how you get monster plants.).you're dedicating your already limited resources into an asteroid hopping mission for very little return.
the technical advancements that would be needed to turn us into essentially space hobos looking for water, would actually be better spent on fixing earth.

If I was to be generous, I would say episode 5 was terrible, episode 4 was acceptable, and episode 6 was pointless.

I mean if you want an extremely volatile bomb to power your ship... NASA already uses liquid hydrogen as rocket fuel for the space shuttle since it’s ~35% better than conventional fuels, combined with liquid oxygen to keep the combustion going.

This is a thread that I found on another website I post at. It can be really really interesting. I thought it deserved a place here.
Post your random thoughts for the day here, or anything else that intrigues you.
For starters, is it possible to give constructive critism to someone who doesn't have a neck? I totally just walked by a girl who didn't. Someone isn't getting a necklace for Valentines day!
And who decided black and white can't be colors? I want to say a racist. I really do.
