NASA spacecraft reaches most distant world explored
LAUREL, Maryland (AP) - NASA's New Horizons spacecraft has survived humanity's most distant exploration of another world.
Ten hours after the middle-of-the-night encounter 4 billion miles (6.4 billion kilometers) away, flight controllers in Laurel, Maryland, received word from the spacecraft late Tuesday morning.
Cheers erupted at Johns Hopkins University's Applied Physics Laboratory, home to Mission Control.
An anxious spill-over crowd in a nearby auditorium joined in the loud celebration.
New Horizons zoomed past the small celestial object known as Ultima Thule 3 1/2 years after its spectacular brush with Pluto.
Scientists say it will take nearly two years for New Horizons to beam back all its observations of Ultima Thule, a full billion miles (1.6 billion kilometers) beyond Pluto.
At that distance, it takes six hours for the radio signals to reach Earth.
