Using a long-shot “shout” maneuver, the Voyager mission team at NASA has reestablished communication with Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years
. “At 12:29 a.m. EDT on Aug. 4, the spacecraft began returning science and telemetry data, indicating it is operating normally and that it remains on its expected trajectory,” according to an update shared by the space agency. Commands sent to Voyager 2 on July 21 accidentally caused the spacecraft’s antenna to point 2 degrees away from Earth. The miniscule shift meant that Voyager 2 couldn’t receive any commands from mission control or send data back to Earth from its location more than 12.
Given the massive distance between Earth and Voyager 2, the team thought there was a “low probability” that the command would work, given that the antenna wasn’t oriented in a way to receive a radio signal, said Suzanne Dodd, Voyager’s project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. It takes about 18.5 hours for the signal to travel one way across the solar system to the spacecraft. Overall, it took 37 hours for mission controllers to learn that the shout worked.
