- the engineering team with NASA’s Voyager 1 spacecraft had been trying to solve a mystery.
- The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.
Since May, the designing group with NASA’s Voyager 1 shuttle had been attempting to settle a secret. The 45-year-old space apparatus appeared to be in superb condition, getting and executing orders from Earth, alongside get-together and returning science information – however the test’s disposition verbalization and control framework (AACS) was sending confusing data about its wellbeing and exercises to mission regulators.
The AACS controls the shuttle’s direction and keeps Voyager 1’s high-gain radio wire pointed definitively at Earth, empowering it to send information home. However all signs proposed that the AACS was all the while working, and the telemetry information was invalid. For example, the information seemed, by all accounts, to be arbitrarily produced or mirrored no conceivable expression the AACS could be in.
In any case, in the present portion of uplifting news, NASA revealed that specialists had found the wellspring of the garbage information: The AACS had begun sending the telemetry information through a locally available PC known to have quit working a long time back, and the PC undermined the data.
A terrible order from another installed PC
Suzanne Dodd, Voyager’s undertaking chief, said that when they thought this was the issue, they selected to attempt an okay arrangement: telling the AACS to continue sending the information to the right PC.
The arrangement was okay yet tedious. A radio transmission requires almost 22 hours to arrive at Voyager 1, which was 14.6 billion miles (23.5 billion kilometers) from Earth and becoming farther continuously as of August 30.
While the issue has been tackled, the group is dubious why it happened in any case.
They suspect the interstellar pioneer started steering its wellbeing and status telemetry through the dead PC in the wake of getting a terrible order from one more locally available PC. That would recommend that some other issue snuck inside Voyager 1’s PC minds. In any case, the mission chiefs don’t think it compromises the space apparatus’ drawn-out well-being.
However to test the main driver
“We’re glad to have the telemetry back,” Dodd said in a proclamation. “We’ll do a full memory readout of the AACS and see all that it’s been doing. That will assist us with attempting to analyze the issue that caused the telemetry issue in any case.”
In any case, they might want to know the wellspring of the secret.
“So we’re hopeful but still sober-minded, however, we actually have more examining to do,” she added.
NASA sent off the Voyager 1 space apparatus and its twin Voyager 2, in 1977, as a component of the NASA Heliophysics System Observatory. The tests were determined to investigate the planetary group’s external planets. The two Voyagers have worked far longer than mission organizers expected and are the main shuttle to gather information in interstellar space, the district outside the heliopause, or the air pocket of lively particles and attractive fields from the Sun. While Voyager 1 flew by Jupiter and Saturn during its essential mission and was placed in interstellar space in 2012, Voyager 2 arrived at the achievement in 2018.
The data the tests give from this district has given a more profound comprehension of the heliosphere, the diffuse boundary the Sun makes around the planets in our planetary group.
