Iรขยยm stranded on Mars.
I have no way to communicate with Earth.
Iรขยยm in a Habitat designed to last 31 days.
If the Oxygenator breaks down, Iรขยยll suffocate. If the Water Reclaimer breaks down, Iรขยยll die of thirst. If the Hab breaches, Iรขยยll just kind of explode. If none of those things happen, Iรขยยll eventually run out of food and starve to death.
So yeah. Iรขยยm screwed.
