Voyager 1 Communication Issue Resolved, Science Data Resumes
NASA Engineers Identify and Correct Computer Glitch
Pasadena, Calif. - December 15, 2023 - NASA engineers have successfully resolved a computer issue that interrupted the flow of science and engineering data from the Voyager 1 spacecraft. The issue, which began on November 14, 2023, was caused by a corrupted data stream.
11 Years in Interstellar Space
Launched in 1977, Voyager 1 and Voyager 2 were groundbreaking missions that explored the outer planets and interstellar space. Voyager 1 became the first spacecraft to enter interstellar space in 2012, while Voyager 2 achieved the same feat in 2018. The spacecraft have been operating seamlessly for decades, providing valuable scientific data on the solar system and beyond.
Identical Computer Systems
Voyager 1 and Voyager 2 have identical computer systems called the Computer Command System (CCS), which serves as the central controller of the spacecraft. The CCS manages all spacecraft functions, including communication, navigation, and science data collection.
Loss of Science Data
On November 14, 2023, Voyager 1 stopped transmitting readable science and engineering data to Earth. Mission controllers could still communicate with the spacecraft, but the data stream was garbled. Engineers suspected a problem with the CCS.
Troubleshooting and Resolution
NASA engineers worked tirelessly to diagnose the issue. They sent commands to Voyager 1 to switch to a backup computer system, but that did not resolve the problem. Eventually, they identified a corrupted data stream in the CCS. By sending specific commands, they were able to reset the CCS and restore the normal flow of data.
Science Data Resumes
With the computer issue resolved, Voyager 1 has resumed sending science data back to Earth. Engineers are analyzing the data to determine any potential impact on the spacecraft's operations. The spacecraft remains in good health and is expected to continue its mission for years to come.
The resolution of the computer issue is a testament to the dedication and ingenuity of NASA engineers. It also underscores the resilience of the Voyager spacecraft, which have pushed the boundaries of space exploration for nearly half a century.
