Video: New Horizons animation

NASA’s New Horizons spacecraft fine-tuned its path toward Pluto on Tuesday, firing its rocket thrusters for 93 seconds to aim for a fleeting flyby of the distant dwarf planet July 14.

Scientists planning the the next phase of NASA’s New Horizons mission, a robotic craft that completed the first exploration of Pluto in 2015, are going into the flyby of a frozen, faraway city-sized clump of rock on New Year’s Day 2019 armed with little knowledge of the target lurking around 4 billion miles from Earth.

A high-resolution scan of Pluto from the New Horizons spacecraft published last week is now available in color, thanks to a new image release from NASA on Thursday showing craters, mountains and glaciers in a new light.
