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.

Now just three weeks from its historic flyby of Pluto, NASA’s New Horizons spacecraft is close enough to detect objects smaller and dimmer than the dwarf planet’s smallest known moon and so far, nothing has been spotted that would pose a threat to the probe as it barrels through the system at more than 30,000 mph, scientists said Tuesday.
With meandering canyons four times as long, and twice as deep, as the Grand Canyon in the American Southwest, the crust of Pluto’s moon Charon may have been shaped by violent eruptions and geology once thought improbable for a small body in the far depths of the solar system, scientists said Thursday.
After an exhaustive search for heretofore unseen rings, small moons or other space debris, senior managers have concluded that NASA’s New Horizons spacecraft, hurtling toward a July 14 flyby of Pluto at more than 30,000 mph, can safely stay on its current course without undue fears of a mission-ending impact.
