Editor’s Notice (8/4/23): On August 4 NASA introduced that it had efficiently reestablished communications with Voyager 2.
Earth could not hear from one in every of its most beloved spacecraft till mid-October due to a glitch that altered Voyager 2’s orientation to our planet. However NASA engineers have caught a “heartbeat” sign that the company says would possibly assist it reestablish communications sooner.

“A sequence of deliberate instructions despatched to NASA’s Voyager 2 spacecraft July 21 inadvertently brought on the antenna to level 2 levels away from Earth,” wrote NASA officers in a July 28 assertion. “Because of this, Voyager 2 is at present unable to obtain instructions or transmit knowledge again to Earth.”
Because the preliminary glitch, NASA has detected what mission personnel name a provider sign from the spacecraft, which confirms that it’s nonetheless working correctly.
“A bit like listening to the spacecraft’s ‘heartbeat,’ it confirms the spacecraft continues to be broadcasting, which engineers anticipated,” wrote officers at NASA’s Jet Propulsion Laboratory, which operates the spacecraft, in a tweet on August 1. “Engineers will now attempt to ship Voyager 2 a command to level itself again at Earth.”

If that doesn’t work, NASA expects Voyager 2 will resume communications in October due to repeatedly scheduled instructions that direct the spacecraft to reset its orientation. The subsequent of those reorientation maneuvers will happen on October 15.
Voyager 2 launched in August of 1977, about two weeks earlier than its twin Voyager 1, which swung previous Jupiter and Saturn, adopted by Titan, Saturn’s largest moon. Voyager 2 took a special path, zipping by Jupiter and Saturn after which Uranus and Neptune. So far, it stays the one spacecraft to ever go to the latter two planets.
The Voyager missions have additionally performed a singular position in American tradition. Every spacecraft carries a golden document: a phonograph that features greetings from languages world wide and a bunch of musical excerpts. Every document is encased in a sleeve that maps Earth’s location with respect to 14 pulsars, that are rotating neutron stars that pulse radiation at very exact intervals. And the Voyager 1 mission captured the enduring {photograph} generally known as the “Pale Blue Dot,” which depicts Earth as a tiny speck in opposition to the vastness of house.

Each probes have continued trekking throughout that vastness. Voyager 2 is now practically 12.4 billion miles from Earth, some 133 occasions our planet’s distance from the solar. Till the glitch, it took practically 18.5 hours for a sign from Earth to achieve the spacecraft and one other 18.5 hours for people to catch a response.
5 devices stay operational on Voyager 2. In 2018 it moved into interstellar house, the place the affect of the solar wanes. Now the spacecraft is working to assist scientists perceive what occurs, as an illustration, the place cosmic rays overpower the photo voltaic wind, the stream of charged particles that always flows off the solar.
Voyager 2’s energy is waning, nonetheless, because it treks ever farther from the solar and its nuclear energy supply ages. NASA has already shut down sure elements to save lots of energy, however quickly officers anticipate to show off further devices in hopes of extending the spacecraft’s operations via 2030—a very spectacular feat, provided that the mission was solely designed to final 4 years.
