NASA's Voyager 1 spacecraft, launched in 1977, has resumed full science operations after a technical issue caused it to send unintelligible data to Earth. The problem was identified and fixed, and the spacecraft is now sending back usable data from all four of its science instruments. Voyager 1 is the most distant human-made object in space, and its continued operation provides valuable insights into interstellar space. The spacecraft's team will continue to perform maintenance and updates to ensure its longevity.
