NASA hears Voyager 2 ‘heartbeat’ after losing touch with interstellar probe

Voyager 2 continues to be broadcasting a “heartbeat” from deep area after a communications breakdown.

NASA’s long-running Voyager 2 mission, which launched from Earth in 1977, robotically despatched a “service sign” picked up by the company’s Deep House Community, company officers said Monday (Aug. 1).

“A bit like listening to the spacecraft’s ‘heartbeat,’ it confirms the spacecraft continues to be broadcasting, which engineers anticipated,” officers with NASA’s Jet Propulsion Laboratory (JPL) stated on Twitter. Canberra, Australia’s DSN Twitter account confirmed the news as effectively.

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 robotically 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 unintentionally 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 area. Engineers even have, to this point, not been in a position to ship instructions to the spacecraft. However Voyager 2’s programming already has backup enabled, because the spacecraft robotically resets its orientation just a few occasions a yr in case of troubles like this.

Voyager 2 flew to area from Launch Complicated 41 at Cape Canaveral, Florida, on August 20, 1977. After swinging by the 4 fuel big planets of the photo voltaic system between the Nineteen Seventies and Nineteen Nineties, it entered interstellar area on Dec. 10, 2018.

Its twin craft Voyager 1 can 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 dropping energy from their nuclear radioisotope turbines, however engineers have made a number of alterations to protect their techniques the place doable. 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 area knowledge assortment till not less than 2026, officers mentioned on the time.
