A spectacular sampling of imagery from NASA’s New Horizons spacecraft reveals mountains and water ice bedrock on Pluto, an active crust on its largest moon Charon and the first resolved views of the icy world’s tiny mini-moons.
A snapshot of Pluto shows fresh deposits of water ice bedrock and 11,000-foot mountains, revealing evidence Pluto’s surface is one of the youngest in the solar system.

The first resolved image of the object shows it to be 28 miles long and 19 miles in diameter, and better images are to come. Credit: NASA/JHUAPL/SWRI
Speeding through the outer reaches of the solar system nearly 3.8 billion miles from Earth, NASA’s New Horizons spacecraft has awakened from a five-and-a-half month slumber, ready for a second act after its 2015 flyby of Pluto with a New Year’s Day encounter with a primordial world set to become the most distant object ever explored.
Images obtained during the New Horizons spacecraft’s July 14 encounter with Pluto show apparent glacial ice flows wrapping around barrier islands and towering mountain ranges, all under a haze layer suspended up to 100 miles above the distant world’s frozen surface.
Now more than two years outbound from its historic encounter with Pluto, NASA’s New Horizons spacecraft is on target for a fleeting flyby less than 2,200 miles from 2014 MU69, an icy, city-sized world set to become the most distant object ever visited, just after midnight Jan. 1, 2019, on the U.S. East Coast. Scientists now say the probe may be able to pursue another destination some time in the 2020s.
