I read up on it, thought about it, and convened with my more-scientific-than-I husband on the subject–but I don’t think the would-be Mars colony is going to make a go of morning coffee or tea to warm them in their new permafrost world. Low air pressure, low air temperature, low boiling point of water—the water would vaporize anyway, given the pressure. . . .I basically decided the people who want to move to Mars probably should, if they’re the sort who see the infinite beauty and gracious bounty of Earth as not what they had in mind for a world. It would almost certainly take more than a minute to receive Kindle books—Amazon probably won’t have Whispersync to Mars for quite a while; and even with potentially loose regs for drones, front-door delivery looks dicey.
