Nasa has “inadvertently” lost contact with Voyager 2, its pioneering spacecraft. The space agency said that it had sent a series of planned commands to the probe on 21 July. But those moves left Voyager 2 pointing in the wrong direction: its antenna is now pointing two degrees away from Earth, and so it has lost contact with its engineers. It cannot either receive commands or send back data, Nasa said. Ordinarily, it would do so by establishing contact with the Deep Space Network, or DSN, which is a set of ground-based antennas that allow for communications with distant spacecraft.
