Wouldnīt growing food mean to create a whole biosphere? We canīt even manage that on earth. See the disaster that was Biosphere 2.

No, your equating the failure of self sustaining biospheres with "growing food". You can grow food in Biosphere 2 quite well. The problem was that they couldn't ever get it to stabilize as a sealed environment. And while a stabilized bisophere would be ideal for colonization, there's nothing wrong with having to import some materials you run short on or dump materials you are in excess of. If you plan appropriately.

I think we just have too many space advocates drinking Ayn Rand Cool-Aid.
NASA should be in business of building rockets--the larger the better. That allows returns.

The folks here are just more examples of people falling all over themselves to keep from building heavy lift. One way missions--they think--require less mass. But they need constant supplies, otherwise you get the nightmare described here:

Ah here we go with the "NASA using it's entire budget to launch a REALLY COOL HLV every 7 years is the way to colonize space" argument. And what the hell does Ayn Rand have to do with anything? You really think Ayn Rand is a big influence on space advocacy??? You really are heading into conspiracy crazy town there.


NASA should be in the business of Aeronautics and Space. Business should be in the business of building rockets.
