NASA’s Voyager 1 probe, located 24 billion km away from Earth, has successfully resumed transmitting data after overcoming some malfunctions that threatened to disrupt its interstellar mission. The Deep Space Network, a system of ground-based radio antennas, played a crucial role in maintaining communication with the probe.
After decoding signals from Voyager 1, NASA engineers discovered that 3% of the flight data system’s memory was corrupted due to a malfunctioning chip. This rendered the scientific and engineering data unusable. To address this issue, engineers decided to store the affected code in other areas of the system’s memory. They had to modify sections of code and update the code’s new location in the system’s memory. A radio signal was sent to the probe on April 18, directing the code to the new location. Confirmation of the successful implementation of the changes was received on April 20.
Launched in 1977, the Voyager 1 probe has exceeded all expectations, operating well beyond its initial five-year goal. The Voyager team remains optimistic despite the challenges posed by time and distance from Earth. As project manager Susan Dodd stated, “We never know for sure what will happen, but it never ceases to amaze me that they are still making progress.”
