The NASA Voyager 1 spacecraft, a marvel of human engineering and the farthest object ever made by humanity, has resumed sending engineering updates back to Earth after five months of silence. This breakthrough provides NASA and the space community with crucial insights into the spacecraft’s health and functionality.
Voyager 1’s Challenges and Solutions
In November 2023, NASA faced a perplexing issue with Voyager 1: the spacecraft stopped sending readable science and engineering data back to Earth. However, it continued to receive commands and operate normally, leaving engineers and scientists baffled. The problem was traced back to a single chip responsible for storing a portion of the memory in one of the spacecraft’s three onboard computers, the flight data subsystem (FDS). This malfunction caused a loss of crucial software code, rendering the data from Voyager 1 unusable.
“The loss of that code rendered the science and engineering data unusable,” explained a spokesperson from NASA’s Jet Propulsion Laboratory (JPL).
The team at JPL, undeterred by the challenge, devised a clever solution to redistribute the affected code across other memory sections within the FDS.
Current Status and Future Plans
By April 18, the reconfiguration of the code had been implemented. The critical test came when a radio signal, after a 22 ½ hour journey to Voyager 1 and back, confirmed the success of this solution.
“When the mission flight team heard back from the spacecraft on April 20, they saw that the modification worked: For the first time in five months, they have been able to check the health and status of the spacecraft,” the JPL team reported.
Looking ahead, the engineers at JPL plan to continue adjusting other affected portions of the FDS software to enable Voyager 1 to start returning scientific data as well.
Historical Context and Significance
Launched over 46 years ago, Voyager 1 and its twin, Voyager 2, have traversed the solar system and now voyage through interstellar space. These spacecraft have provided humanity with unprecedented views of the outer planets and are now sending back information from beyond the heliopause, where the solar wind is stopped by the interstellar medium.
Open hailing frequencies, we have reestablished communication…
