NASA Voyager 1 Space Probe From the '70s Afflicted by Mysterious Glitch - CNET
NASA's 45-year-old Voyager 1 spacecraft is a marvel. It's cruising along outside our solar system and still staying in touch with Earth.The issue likely traces to Voyager 1's attitude articulation and control system (AACS), which handles its orientation in space, including the task of keeping its antenna pointed at Earth.The data isn't making sense, but Voyager 1 is maintaining a clear line of communication with home and the problem hasn't triggered a protective "safe mode." ?The twin spacecraft Voyager 1 and Voyager 2 launched in the 1970s and have long outlasted their expected lifespans.They're both in interstellar space, which Voyager 1 and 2 project manager Suzanne Dodd describes as a "high-radiation environment that no spacecraft have flown in before.".
