Mars And SLS

I really find Chris Carberry’s op-ed on SLS incomprehensible. Oh, I don’t mean I don’t understand it, it just seems disconnected with reality, and the interests of anyone seriously interested in seeing humans go to Mars. He speaks about SLS as thought it has kind of reality, and actual utility. To me, a sane Mars organization would be screaming bloody murder at the waste of money to the detriment of hardware needed to actually get to Mars.

Martin Elvis says it’s a game changer. BFR would be even more so. But this (from the story’s author) is a little silly:

Also, I feel like launching all of those rockets and processing the metals can’t be good for the environment.

The metals would be processed in space. The whole point of this is to start to move industry off the planet, which would be great for the environment. He should try thinking, and doing some actually analysis, rather than going on feels.

This seems related, sort of: Planetary Resources has a funding shortfall.

Seems like those billionaires who supposedly founded it don’t actually have that much faith in the venture.
