NASA’s Voyager 1 probe is currently unable to transmit any scientific or systems data back to Earth. The 46-year-old spacecraft is capable of receiving commands, but a problem seems to have arisen with the probe’s computers.
Voyager 1’s flight data system (FDS), which collects onboard engineering information and data from the spacecraft’s scientific instruments, is no longer communicating as expected with the probe’s telecommunications unit (TMU), according to a NASA blog post on Dec. 12.
When functioning properly, the FDS compiles the spacecraft’s info into a data package, which is then transmitted back to Earth using the TMU. Lately, that data package has been “stuck,” the blog post said, “transmitting a repeating pattern of ones and zeros.” Voyager’s engineering team traced the problem back to the FDS, but it could be weeks before a solution is found.
