NASA’s New Horizons spacecraft begins first phase of historic encounter with Pluto
NASA’s New Horizons spacecraft had officially commenced its first ever remarkable encounter with Pluto recently.
The spacecraft is entering the first of several approach phases that culminate July 14 with the first close-up flyby of the dwarf planet, 4.67 billion miles (7.5 billion kilometers) from Earth.
The fastest spacecraft when it was launched, New Horizons lifted off in January 2006. It awoke from its final hibernation period last month after a voyage of more than 3 billion miles, and will soon pass close to Pluto, inside the orbits of its five known moons.
