NASA's Voyager 1 spacecraft has resumed sending back science data after a six-month glitch caused by corrupted memory in its flight data subsystem. The probe, which has been operational for over 46 years and is now in interstellar space, is once again providing valuable information about the space between stars.
NASA engineers have identified a small portion of corrupted memory in the flight data subsystem (FDS) as the cause of Voyager 1's unreadable data transmission, likely due to a malfunctioning chip. The issue, possibly caused by an energetic particle or the age of the silicon, has hindered the spacecraft's normal operations. It may take weeks or months to find a solution, but NASA remains optimistic about restoring Voyager 1's ability to send usable science and engineering data.
NASA engineers have identified corrupted memory hardware in the Voyager 1 spacecraft's flight data system as the cause of the probe sending nonsensical data to mission control. The issue began in May 2022 and resurfaced in December 2023, prompting the team to send a command to pinpoint the corrupted section. Approximately 3% of the FDS memory has been corrupted, hindering normal operations, but the engineers are working on finding a solution to enable Voyager 1 to resume transmitting data and continue its deep space journey.
Researchers from Aston University in the UK have achieved transmission speeds of 301,000,000 megabits per second using existing fiber optic infrastructure, surpassing average broadband speeds by 4.5 million times. By utilizing previously unused wavelength bands, the researchers were able to significantly increase data transmission rates without the need to replace current fiber infrastructure. While not the fastest transmission ever achieved, this breakthrough could lead to substantial advancements in data delivery capabilities.
Voyager 1, the farthest human-made object, has been sending a repeating pattern of 1s and 0s to NASA from interstellar space, likely due to an issue with its Flight Data System. This has halted the transmission of science data and updates about the probe's health and status. NASA is working to resolve the problem, but it may take months, and the spacecraft's plutonium-powered system is running out. Eventually, Voyager 1 will cease sending data, but it will continue its journey through the space between stars.
NASA's Voyager-1 spacecraft, currently outside the Solar System, is experiencing a data transmission issue, preventing it from sending science data back to Earth. The problem lies with the flight data system (FDS) not communicating properly with the telemetry modulation unit (TMU). Despite efforts to resolve the issue, the spacecraft has been unable to return usable data since December. Launched in 1977, Voyager-1 provided valuable insights into the outer planets and entered interstellar space in 2012, making it the farthest human-made object in space.
