NASA reestablished contact with Voyager 2 in interstellar space after days of silence

NASA has finally reestablished contact with Voyager 2 after several days of silence, despite being billions of miles away in interstellar space.

The spacecraft’s antenna had inadvertently been tilted away from Earth due to a mistaken command sent by flight controllers nearly two weeks ago, leading to a loss of communication. However, the giant radio antennas of NASA’s Deep Space Network detected a “heartbeat signal,” indicating that the 46-year-old Voyager 2 is still operational.

The news brought relief and excitement to the project manager, Suzanne Dodd, who mentioned that they will now attempt to realign the spacecraft’s antenna towards Earth. Nevertheless, there are doubts about the success of this maneuver, as the antenna is currently only 2% off its proper alignment.

If the upcoming command fails, the team will have to wait until October for an automatic reset of the spacecraft. This extended waiting period highlights the challenges of interstellar communication, with Voyager 2 being located more than 12 billion miles away from Earth, resulting in signal delays of over 18 hours.

Voyager 2, launched alongside its twin Voyager 1 in 1977, was initially sent to explore the outer planets. Voyager 1 holds the record for being the most distant spacecraft, still communicating effectively at a distance of 15 billion miles from Earth. In comparison, Voyager 2 is trailing slightly behind in interstellar space, more than 12 billion miles away from our planet.
