Yeah, by being fully made of those. [SPOILER ALERT]
* lack of crew psychological cross-matching
* some ludicrously exoggerated hydrazine drama
* chloroplast-equipped organisms in the environment which ambient light spectrum is slightly inclined towards gamma radiation (not to mention the meat-packed space vessel itself, brightly shined up by very same light)
* _one_ central computer with sole purpose to be heroically repaired on the _outer_ shell of the vessel (you see, no EVA - no drama)
* (mentioned ending) transferring at least tens of gigabytes from Europe to Earth in a matter of seconds (via that special hero-driven central computer) despite being unable to establish uplink for past several months already due to the broken trasmitter (of course, unreserved)

Well, I understand that this is just a movie, but look, why not to put it in agreement with some common sense?
