not about technology, but the 'rescue attempt' if something like in movie (or in novel) really happen. if state were to spend a several billion to rescue one single man form mars.... are they gonna do it? or is it possible for them to keep silent and let the mars kill him to save money? I didn't mean to see humanity in bad ways but... just possibility. ps. English is not my native language, for give me if I'm wrong in spelling or grammar.
