NASA engineers are a step closer to solving the communication problem that left the Voyager 1 spacecraft, which presently sits outside the solar system, unable to send usable data back to Earth.. For 11 years following this achievement, the spacecraft dutifully sent data to ground control. This was data that detailed how space works beyond the influence of the sun. In Nov.
Voyager 1's messaging to Earth comes in the form of 1s and 0s, a computer language called binary code — but since the end of last year, this code has carried no meaning. Even the newly detected signal is still not in the correct format Voyager 1 should be using when FDS is functioning as designed, meaning the operating team was initially not quite sure what to make of it.
That means the results of NASA's poke were received on March 3, and on March 7 engineers started working to decode this signal. Three days later they determined the signal contains an FDS memory readout.
