NASA’s Voyager 1 phones home after months

-

WASHINGTON: NASA’s Voyager 1 probe — the most distant manmade object in the universe — is returning usable informatio­n to ground control following months of spouting gibberish, the US space agency announced Monday.

The spaceship stopped sending readable data back to Earth on November 14, 2023, even though controller­s could tell it was still receiving their commands.

In March, teams working at NASA’s Jet Propulsion Laboratory discovered that a single malfunctio­ning chip was to blame, and devised a clever coding fix that worked within the tight memory constraint­s of its 46-year-old computer system.

“Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineerin­g systems,” the agency said.

“The next step is to enable the spacecraft to begin returning science data again.”

Launched in 1977, Voyager 1 was mankind’s first spacecraft to enter the interstell­ar medium, in 2012, and is currently more than 15 billion miles from Earth. Messages sent from Earth take about 22.5 hours to reach the spacecraft.

Its twin, Voyager 2, also left the solar system in 2018.

Both Voyager spacecraft carry ‘Golden Records’ — 12-inch, goldplated copper disks intended to convey the story of our world to extraterre­strials.

These include a map of our solar system, a piece of uranium that serves as a radioactiv­e clock allowing recipients to date the spaceship’s launch, and symbolic instructio­ns that convey how to play the record.

The contents of the record, selected for NASA by a committee chaired by legendary astronomer Carl Sagan, include encoded images of life on Earth, as well as music and sounds that can be played using an included stylus.

Their power banks are expected to be depleted sometime after 2025.
