I love how "safe mode" for a satellite is basically: "extend solar panels, turn self towards sun, don't do anything unnecessary, wait for further instructions".
It'd be easy to optimize with some additional religions too, since from that distance pretty much all possible Earthly [0] holy sites are in the same direction.
[0] I just stumbled onto a fun grammar question! Is it "earthly" (non-supernatural) or is it Earthly (proper-adjective related to the planet), or both? I submit that it's possible to have an "earthly Martian holy-site", and therefore only the capitalized version works here. :p
