Yes, I’m super behind on my movie watching but I finally watched “The Martian” over the weekend and wow did it absolutely spark my interest in space travel and the feasibility of living on Mars for months including growing your own food…what? By the way, if you haven’t seen it yet stop reading this immediately and go watch it. It’s completely worth it and this post will spoil it for you.
First off, The Martian does a great job and gets some stuff right, but then again this is science fiction and so there has to be some fictional things but what “The Martian” does is not over exaggerate a ton of things making almost all of it very believable. One blatant thing that they screwed up was the storm at the beginning that stranded the astronaut on Mars after he was hit by the communication tower that the wind knocked over. The dust storm certainly could occur but not to the level it was dramatized because of the incredibly thin atmosphere Mars has. So the storm couldn’t have happened, however, a lot of other things they got right.
For instance, all the orbital dynamics and the time it would take to travel between Mars and Earth was completely dead on and one scientist even acclaimed the movie for doing the computations to determine how long the trips would take. On top of this, the slingshot the Hermes Spacecraft undertook around Earth to head back to Mars was entirely feasible as gravity assisted speed boosts are used to help satellites obtain more speed all the time.
The last two things I wanted to talk about was the ability to grow potatoes on Mars and taking off from mars in a deconstructed rocket. After doing research, I found out that the way Watney grew potatoes was entirely feasible as Martian soil can sustain food growth especially with using feces as fertilizer and obtaining water the way he did, so, in essence, his ability to grow food on Mars is plausible.
Last, what I thought was most ridiculous, was when Watney basically stripped the rocket of its nose cone and other portals so he was essentially flying into space in an open cockpit. I thought there was absolutely no way this could happen. Well, it sort of is and sort of is not feasible. I say this because currently we do not have the technology to take off from Mars because NASA has absolutely no idea how to launch a rocket from Mars at the current point in time so, in that case, it is not possible. However, the fact that the windows are off is potentially possible because the atmosphere is so thin, by the time friction (which would develop heat and thus require the heat shield to protect against the atmosphere) played a factor, it would be negligible. Therefore, it is plausible to launch a spacecraft like that.
All in all, “The Martian” does probably the best job yet of abiding to science when creating a science fiction movie and it was applauded by many scientists as well as checked by NASA to prove it was mostly valid despite a few snafus. If you haven’t seen it yet, I would strongly suggest you go see it immediately.
