NASA is engaged on a repair, which is difficult by the billions of miles between the craft and Earth.
NASA’s Voyager 1 spacecraft is depicted on this artist’s idea touring via interstellar house, or the house between stars, which it entered in 2012. Touring on a distinct trajectory, its twin, Voyager 2, entered interstellar house in 2018.

Voyager 1, probably the most distant human-made object from Earth, is behaving surprisingly. It’s not simple to diagnose and repair issues from 15.1 billion miles (24.4 billion kilometers) away, however NASA is attempting.
NASA reported Dec. 12 that the probe’s flight information system (FDS) — consisting of three onboard computer systems — is sending nonsense binary information again to Earth. The combo of ones and zeros is coming in a repeating sample that seemed to be “caught.” Earlier than you ask, sure, they tried rebooting. In accordance with a NASA news release, the group tried to restart the FDS, but it surely didn’t assist.
Andrew Good works in media relations for the Jet Propulsion Laboratory and emailed astronomy.com an replace from Voyager mission supervisor Suzy Dodd. They’re working diligently to repair it, and there was no signal of an issue earlier than it occurred.
The group is on the lookout for an answer by inspecting outdated paperwork, and ensuring to not overwrite important code. A problem with fixing the issue is the size of time it takes to ship and obtain messages. As a result of the spacecraft is in interstellar house, it takes 22-1/2 hours for any form of patch to succeed in the probe and the identical size of time to search out out if it labored.
In the meantime, the similarly-named Voyager 2 is 12.6 billion miles (20.2 billion km) away, and is working usually after a communication glitch over the summer time. Scientists are hopeful it’ll proceed to perform till its energy provide runs out someday after 2026.

The 2 spacecrafts are the one human-made objects to enter interstellar house from Earth. Each carry the Golden Record, a group of photos and sounds chosen by Carl Sagan and associates.
