Voyager 2 is back, baby.
NASA is back in touch with the Voyager 2 spacecraft following an antenna accident that left it cruising through beyond the outer part of our solar system alone.that inadvertently caused the antenna to shift .2 degrees away from Earth. This miniscule adjustment meant that NASA's Deep Space Network was unable to contact Voyager 2, which is currently sailing out of our solar system 12.3 billion miles away.
At the time, NASA expected the spacecraft to remain uncontactable until October, when the craft's automated realignment would hopefully bring the antenna back around to Earth's location. On August 1, NASA detected a heartbeat from the spacecraft—a faint glimpse of the carrier signal used to transfer data to and from Earth. This offered an opportunity to get in touch a little sooner than expected, and lo and behold, it worked.
To make sure Voyager 2 received the signal from Earth to rotate its antenna, NASA had to"shout it" through space in the craft's general direction. A call to say 'we're over here' and hope Voyager 2 responds. After 37 hours of waiting to see if it worked—it takes 18.5 hours for a message to travel one-way to Voyager 2—NASA command heard back.
"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,"
