ISS gets delivered tons of stuff regularly, stuff that has been produced using the full extent of all supply chains of the whole planet Earth. All dreams of replicating just a tiny part, only the most necessary parts, of these supply chains on Mars are delusional, and that’s at the low level necessary to support only two humans (probably women as they’re much more resilient, gritty and persistent than male astronauts).

And again: For what? Simply to prove “we can”? The money this hazardous endeavour would cost would better be spent improving living conditions on planet Earth. If you want to replicate life on Mars do one of the “1.000 days in an sealed off enclosure”-experiments here on earth - saves tons of money (literally) and is much less deadly.

I won’t interfere with that community as it’s a nice game of thoughts and ideas and probably has a lot of entertaining and informative aspects. Have fun 👋
