Voyager 1, the farthest human-made craft from the Earth, is finally sending back data from all four of its scientific instruments, NASA said this week. That means the agency is once more receiving its readings on plasma waves, magnetic fields, and space-bound particles.Now, NASA says Voyager 1, which is over 15 billion miles from Earth, is “conducting normal science operations” and the agency just needs to resync its timekeeping software and do some maintenance on a sparingly-used digital tape recorder.
