What would it take to build a self-sustaining astronaut ecosystem on Mars?
What would it take to build a self-sustaining astronaut ecosystem on Mars?
We're getting closer to bioregenerative life support systems for astronauts.
You're viewing a single thread.
Who cares? Mars is nightmarish and those resources are better spent saving Earth.
Apparently poop + potatoes according to the documentary
You know you also need other infrastructure for people to live there.
And you need to get all of that to mars.
And you need to keep up the logistics between two different planets, it's not just send one or two payloads and you're done.
Yeah I was gonna say “one dude and a bag of shit”
Eventually, either through choice or because of climate change, we'll go up. And this work is important for that.
However harsh and hostile Earth can become due to climate change. Rest assured, Mars is harsher and more hostile.
Whatever terraforming efforts we put into Mars to change that, would be easier, cheaper and more effective put into Earth.
Other factors favor Earth over Mars which are entirely unaffected by climate change:
- Earth's gravity is ideal for us
- We have all our scientists, workers, vehicles, machines, resources and infrastructure here, not there
- Earth has a magnetic field which shields us from cancer-inducing cosmic radiation. Mars does not.
- Marth has sharp dust particles flying around, which are a nightmare for surface machinery. Earth does not.
- ...
There literally is no planet B. Also, tomorrow (15th Sept) is another FFF strike (on Earth).
That's a damn good explanation
what's a FFF strike?
Fridays For Future is a movement started by Great Thunberg. It's goal is to put pressure on politics to fulfill the Paris agreement.
FFF is doing strikes every Friday, with major events once in a while. Before the Covid pandemic, participant numbers reached millions worldwide. The next big one is today, with events around the globe: https://fridaysforfuture.org/action-map/map/
In practical terms, a FFF strike is a regular, orderly, peaceful, announced demonstration, free and safe for everyone to participate. If your country supports these citizens rights, of course.
Thanks! How did it go?
Very well! Sunny weather, much more people than expected, good speeches, funny posters, amazing bands, no serious incidents. Now all that's missing is politics listening to the scientist.
Nice 🙂
I disagree that Martian colonization in inevitable. I'd like to see it, but I'd also like to end poverty.
If we can prioritize sustainability research and development by calling it a Mars mission I'm not inherently opposed.
There's basically no chance of Mars ever being more habitable then Earth, the atmosphere is 100x thinner there. Like even in the worst climate change scenario you can imagine we'd still be better off living here.
You're right, it's totally easier to colonize another planet than it is to mitigate the effects of climate change 🤦
Politically, yeah.
People in power or with money might go. You and me will stay so we better treat earth right :)
