Post Can Mars storms blow away a man?   Posted on: Thu Jun 11, 2015 9:48 am
I've read a best-selling novel "The Martian" written by Andy Weir and now there is the first official trailer of the movie version. But one question is still bugging me.

"How can Mars dust storms be strong?" "Can they blow away a man?"

As far as I know, the Martian atmosphere is very thin so no matter how strong Mars storms may be, it might not be possible that an astronaut is blown away by the wind.

Am I wrong?

No you are not wrong IIRC the author admitted the thing about falling over in a storm was wrong on a bbc radio 4 interview possibly kept in for dramatic effect but much of the science was well researched for fixing up and keeping alive but any astronaut in those circumstances would have to be both very lucky and genius levels of recall. And i seem to recall something was found out later by one of the current probes that means that there would be easier ways of doing one of the fixes to survive possibly to do with the recovery of water

Speaking of water, I was grimacing at the scene where he burns the hydrazine - *without* wearing a spacesuit. I know he draped a canopy over it, but still... hydrazine...

He doesn't burn the hyrdrazine, he dissociates it with a catalyst to N2 and H2 and then burned the resulting hydrogen with O2 to produce water vapor. The plastic was to catch the water for the plants and keep most of it out of the rest of the hab.

Go read the book. :P

Yes, but that still involves hydrazine.

HYDRAZINE.

I would not want to bath in the stuff but after reading the safety sheets on hydrazine I don't think its as a big a Bogeyman as it is often presented. But not something you want to hang around for protracted periods.

Though of course hydrazine near certain oxidisers can be a bit more entertaining when used as a hypergolic fuel se RI vid below
