The only thing that can block me right now is the universe. Lies not in the stars, but in ourselves. Shakespeare had this figured out. All of astrology. The fault. Oh, yes. Frank came. How did early spacecraft like Voyager navigate so precisely over large distances without the benefit of digital computers or high resolution digital cameras? Good question, because Voyager was launched like back in like the 70s. So they had those disposable cameras important. And by the way, when you are launching a probe to a planet, you don't send it to where it is. You send it towhere it will be when it gets there.
