Voyager 1 returning science data from all four instruments

NASA's Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.

The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data.

Two of the four returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.

The four instruments study , magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample , which is the region outside the heliosphere—the protective bubble of magnetic fields and solar wind created by the sun.

While Voyager 1 is back to conducting science, additional minor work is needed to clean up the effects of the issue. Among other tasks, engineers will resynchronize timekeeping software in the spacecraft's three onboard computers so they can execute commands at the right time.

The team will also perform maintenance on the digital tape recorder, which records some data for the plasma wave instrument that is sent to Earth twice per year. (Most of the Voyagers' science data is sent directly to Earth and not recorded.)

Voyager 1 is more than 15 billion miles (24 billion kilometers) from Earth, and Voyager 2 is more than 12 billion miles (20 billion kilometers) from the planet. The probes will mark 47 years of operations later this year. They are NASA's longest-running and most-distant spacecraft. Both flew past Jupiter and Saturn, while Voyager 2 also flew past Uranus and Neptune.
