NASA’s Voyager 1 Resumes Communication After Five Months of Silence

NASA’s Voyager 1 spacecraft, currently cruising in interstellar space, has re-established contact after a five-month communication blackout due to a glitch in November. The spacecraft’s team traced the problem to a single chip in the flight data subsystem, which holds some of the software code for preparing science and engineering data. The team has devised a complex fix involving dividing and storing the code in different places, starting with the code that allows Voyager 1 to package up its engineering data. The team will continue to relocate and adjust the other affected portions of the software in the coming weeks, including those responsible for returning science data. Despite its age, Voyager 1 continues to collect data on interstellar space. The Voyager missions, launched in 1977, are nearing their end, but NASA hopes to keep at least one instrument operating on each spacecraft until around 2025.
