The previous record breaker was the European Space Agency’s Rosetta.
Rather than rest on its laurels after making its historic Pluto flyby, the New Horizons spacecraft will aim for a new icy target floating in the Kuiper Belt.
NASA's new full-color images reveal that Pluto's hazy atmosphere shines a brilliant blue, and beneath that sapphire haze lies several expanses of water ice.
New images of Pluto’s moon sent back from New Horizons reveal an amazingly diverse landscape that suggests a troubled geological past.
A spacecraft with lofty sightseeing ambitions but low on fuel may be able to latch onto passing celestial bodies and use them to swing from comet to asteroid.
NASA combined the latest images from New Horizons's flyby of Pluto into a stunning animation that gives us a glimpse of the dwarf planet's majestic and distinct surface features.
A curious orbital pattern among objects in the Kuiper Belt points to the presence of a hidden planet at the very edge of the solar system, too far for us to detect but large enough to exert strong gravitational effects on surrounding celestial bodies.
