NASA’s Voyager 1 spacecraft, launched in 1977 and now exploring the outer reaches of our solar system, is experiencing an issue with its attitude articulation and control system (AACS). This system ensures the spacecraft’s antenna remains pointed precisely at Earth, enabling the transmission of data. While the AACS is still operating, the issue has put the spacecraft’s attitude control in a mode that allows for some level of system performance. NASA engineers are working to adapt the spacecraft’s operations to accommodate the situation. Despite the challenge, Voyager 1 continues to return scientific data from its journey beyond our solar system. The spacecraft’s power supply remains stable, thanks to its nuclear power source. NASA remains committed to extending Voyager 1’s mission for as long as possible, given its remarkable journey and groundbreaking discoveries.
