    There’s a disturbing lack of hibernation in our space-faring plans. In movies and books, astronauts pop in and out of hibernation—or stasis, or cryogenic sleep, or suspended animation, or something like it—on a regular basis. If we ever figure out some kind of hibernation, can we take advantage of it to get by with smaller …
