[qosfcovo] Kill All Martians

in the 1990s, a NASA engineer, as a joke, inserts code into a Mars lander instructing it to Kill All Humans once it lands on Mars.  (it was ludicrous to imagine humans could have made it to Mars during the lander's one-month expected mission duration.)

many decades later, Matt Damon gets stranded on Mars and approaches the lander, intending to scavenge it for parts.
