In a conference room at NASA's Jet Propulsion Laboratory in Southern California, members of the Voyager mission team gathered April 20, 2024, to find out if an issue on Voyager 1 had been partially resolved. Just after 6:40 a.m., a cheer went up around the room as the group heard back from the spacecraft: It was returning engineering data for the first time since November 2023. Nearly two full days earlier, the team had sent a series of commands to move a section of software code used by the flight data subsystem (FDS) computer to a new location. The physical location where the code was previously stored has been damaged, causing the mission to go five months without receiving science or engineering data. But the commands were a success, and the team received data about the health and status of the spacecraft, prompting celebration. The commands were sent on April 18, 2024. Due to Voyager 1's distance from Earth – over 15 billion miles or 24 billion kilometers – a radio signal takes about 22 ½ hours to travel to the spacecraft, and 22 ½ hours to return to Earth. https://photojournal.jpl.nasa.gov/catalog/PIA26275
