NASA's Voyager 1 spacecraft, which has been traveling through interstellar space for the past 47 years, recently lost contact with Earth. However, thanks to a radio transmitter that had not been used since 1981, the American space agency was able to re-establish communication with the spacecraft. This unexpected reconnection occurred after the team hypothesized that Voyager 1's fault protection system had triggered and switched to an alternate radio transmitter. The success of this reconnection marks a major milestone for the Voyager mission and opens up new possibilities for communication with the distant spacecraft.
