The Voyager 1 probe, launched by NASA in 1977, continues to transmit data from interstellar space despite its record-breaking distance from Earth and depleting power source. Currently located approximately 25 billion kilometers from Earth—over 170 times the distance between Earth and the Sun—a radio signal sent to Voyager 1 takes over 22 hours to reach it, and this time could increase to a full day by the end of the year. The spacecraft uses radioisotope thermoelectric generators to convert heat from decaying plutonium into electricity, but its power has decreased significantly since launch. Engineers are gradually shutting down secondary systems to ensure the most critical instruments continue functioning. By November, Voyager 1 is expected to reach a symbolic milestone of one light-day from Earth, meaning signals will take nearly 24 hours to travel to and from the probe.
