Engineers from NASA have restored the correct data transmission of the Voyager 1 probe.The cause of the error was
In May of this year, Voyager 1 surprised scientists when it began sending back strange data fromInitial control showed that the spacecraftworks correctly, but all the data coming from it is transmitted with an error and does not reflectreal state.
As a result of the analysis, the engineers found thatthe cause of the breach in the composition of the data is related to the old on-board computer, which failed several years ago. As a result of a software glitch, Voyager 1 began sending data through an old device, which distorted the information during the encoding process.

By reconfiguring the transmission through the main on-board computer, the engineers fully restored the correct signal.The researchers note that it is not yet clear why the spacecraft is using the old device again.Probably, such a command was mistakenly given by the main onboard computer controlling the mission.
This indicates that the device maythere are other problems that led to the primary failure. Engineers continue to look for the root cause of the error, but they are confident that it does not threaten the normal operation of the spacecraft.
Voyager 1 and its twin, Voyager 2, are space probes developed by NASA to explore the gas giants of the solar system.After the orbit of the planet at the end of the main mission, both probes continued to work.They were the first artificial spacecraft to cross the heliopause and are now moving in the direction of the Oort Cloud.
Previously, Hi-Tech spoke in detail about the main achievements of the mission, which has been going on for 45 years.
