Voyager 2 remains to be broadcasting a “heartbeat” from deep house after a communications breakdown.
NASA’s long-running Voyager 2 mission, which launched from Earth in 1977, mechanically despatched a “service sign” picked up by the company’s Deep House Community, company officers acknowledged Monday (Aug. 1).
“A bit like listening to the spacecraft’s ‘heartbeat,’ it confirms the spacecraft remains to be broadcasting, which engineers anticipated,” officers with NASA’s Jet Propulsion Laboratory (JPL) acknowledged on Twitter. Canberra, Australia’s DSN Twitter account confirmed the information as properly.
JPL will subsequent ship a command to Voyager 2 asking the spacecraft to level itself to Earth. “If that doesn’t work, we’ll have to attend till October, when the spacecraft’s onboard software program mechanically tells it to reset its path,” the assertion added.

The spacecraft, which is about 12.4 billion miles (19.9 billion kilometers) from Earth, misplaced contact with our planet after a set of instructions by chance moved Voyager 2’s antenna two levels away from Earth.
The error severed the hyperlink to the bottom antennas of the DSN, stopping Voyager 2 from sending again knowledge in interstellar house. Engineers even have, thus far, not been in a position to ship instructions to the spacecraft. However Voyager 2’s programming already has backup enabled, because the spacecraft mechanically resets its orientation a couple of instances a yr in case of troubles like this.
Voyager 2 flew to house from Launch Complicated 41 at Cape Canaveral, Florida, on August 20, 1977. After swinging by the 4 gasoline big planets of the photo voltaic system between the Seventies and Nineteen Nineties, it entered interstellar house on Dec. 10, 2018.
Its twin craft Voyager 1 can also be operational, flying far-off at about 15 billion miles (24 billion km) from Earth. It was the primary object to maneuver past the gravitational affect of our star, the solar, in 2012.
The missions are slowly shedding energy from their nuclear radioisotope mills, however engineers have made a number of alterations to protect their methods the place attainable. The warmers have been shut off, for instance, and in April 2023 engineers disabled Voyager 2’s surge protector (or voltage regulator).
These steps take away a little bit of backup for the spacecraft whereas permitting their energy provides to last more. The 2023 step alone has postponed one of many instrument shutdowns for Voyager 2 by three years, extending house knowledge assortment till a minimum of 2026, officers mentioned on the time.
