Cole asked Andy Weir:

Did you do a lot of the scientific work proactively or in the editing process? It sounded so precise I couldn't wrap my head around trying to formulate a scene around having to explain his actions in such detail.

Michael

Michael asked Andy Weir:

A manned mission to Mars in the next couple of decades has been talked about by a lot of organizations (NASA for one). What do you see as the biggest roadblock that our current society has created to make this happen? And what is your best idea to change that?

Riku Sayuj

Riku Sayuj asked Andy Weir:

Hi Andy, the only thing I was slightly uncomfortable was about the farming -- can gut bacteria so easily do the work expected of soil bacteria? Aren't gut bacteria mostly anaerobic? And what of nitrogen fixing? I am sure I am missing something, but it would be great if you could clear this up and make the whole thing seamless for this fan!
