NASA builds for keeps: Voyager mission still going after 45 years
The most distant human-made objects, Voyager 1 and 2, are still cruising in interstellar space, more than 12 billion miles from Earth, as NASA today celebrates the 45th year of its longest-operating mission.
NASA hatched a plan to visit these planets after astronomers realized they were due to line up in a way that would give spacecraft a handy gravity assist to hop to the next planet along, starting with Jupiter. Voyagers 1 and 2 remain the only human-made objects we're aware of to have reached ice giants Neptune and Uranus, though the probes are mostly celebrated today for flying even further – crossing the Sun's heliosphere and going beyond.
