SPACECRAFT COMMUNICATION
The farthest human-made object is now so distant that even light takes nearly 24 hours to reach it; exactly 49 years after NASA launched Voyager 1 to explore Jupiter and Saturn, the spacecraft is still in interstellar space and sending data back to EarthThe Voyager 1 probe, launched in 1977, is now over 15.9 billion miles away. This spacecraft has ventured into interstellar space, sending v...- In 1965, MIT's LES-1 failed to reach its planned orbit and fell silent in 1967; 45 years later, the zombie satellite unexpectedly began transmitting againA surprising discovery was made in 2012 when an old satellite from the 1960s unexpectedly resumed broadcasting signals. Originally believed...
