Voyager 1, Launched in 1977, Now Takes Over 22 Hours to Receive a Signal
NASA's Voyager 1, launched in 1977, remains the farthest human-made object in space, currently located approximately 25 billion kilometres from Earth. Nearly 49 years into its mission, the spacecraft continues to transmit data back to scientists. Due to a gradually depleting power supply, NASA has been selectively shutting down onboard systems to extend the probe's operational life. By 2026, the signal travel time between Earth and Voyager 1 is expected to reach a full 24 hours, marking another significant milestone in the mission.
