Following five months of issues, NASA’s elderly Voyager 1 is operational once more – CNN 10.

Overview of Voyager 1’s Recent Challenges

In an unprecedented era of space exploration, NASA’s Voyager 1 spacecraft, which has been traveling through space since 1977, has faced a series of technical difficulties over the past five months. This veteran of the cosmos, now over 14 billion miles away from Earth, encountered issues that challenged its operational capabilities and threatened its ongoing mission to transmit data back to scientists on Earth.

The Nature of the Technical Issues

The primary problem involved Voyager 1’s orientation. The spacecraft’s attitude articulation and control system (AACS), which helps maintain its antenna pointing precisely toward Earth, began sending back anomalous data, suggesting that it was not operating correctly. This misalignment led to a significant reduction in the data transmission rate, as the signals became misdirected into space rather than reaching Earth.

Steps Taken to Resolve the Issues

Upon recognizing the problem, NASA engineers embarked on a troubleshooting mission, which proved to be a monumental task given the spacecraft’s vast distance from Earth. Signals from the control center take over 21 hours to reach Voyager 1, and the same amount of time is required for the responses to come back, resulting in a challenging delay in real-time diagnostics and repair.

Use of Redundant Systems

The team decided to switch to backup hardware that had not been in use for several years. This risky maneuver involved reactivating systems and ensuring they could operate correctly after decades of dormancy. Remarkably, the backup systems were responsive and allowed the mission team to regain stable control of Voyager 1.

Current Status and Future Outlook

As of today, Voyager 1’s systems are fully operational once again. The spacecraft continues its primary mission, which is to gather and transmit scientific data, including measurements of cosmic rays, magnetic fields, and densities of interstellar medium in space. These data are invaluable for understanding more about the universe beyond our solar system.

Implications for Long-Term Space Missions

The recent problems and successful recovery of Voyager 1 highlight the challenges of maintaining and controlling spacecraft that are far from Earth. The incident serves as a valuable lesson for future missions, emphasizing the need for robust, reliable systems and backup plans that can be activated even decades after launch.


The successful revival of Voyager 1 not only secures continued scientific returns but also stands as a testament to the enduring ingenuity and dedication of NASA’s engineering teams. As Voyager 1 and its twin, Voyager 2, journey onward into the unknown, they continue to be harbingers of human curiosity and ambition, pushing the boundaries of human achievement in space exploration.
