NASA is updating the 70-meter radio antenna in Canberra, Australia that is used to communicate with the Voyager 2 and other missions. While other, closer missions can also chat with smaller dishes, only this great disk is capable of sending the powerful signals needed to send new commands to Voyager 2. It’s estimated that the upgrades will take about 11 months to accomplish, and during that time we’ll be able to receive data from Voyager 2 using other dishes, but while we can listen, we won’t be able to talk back. This shouldn’t have a major impact on this distant mission, but if something goes sideways and it cries out for help, we’re going to not be able to respond.
