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
As NASA’s New Horizons probe closes in on Pluto, the Hubble Space telescope has been scouting its retinue of five known moons, discovering that at least two are tumbling chaotically in the complex gravity of the dwarf planet and its large moon, Charon, researchers said Wednesday.
The final days before NASA’s New Horizons probe barrels in on its next destination on Jan. 1, 2019, should prove eventful, with scientists trying to sort out whether a distant mini-world detected by the Hubble Space Telescope more than three years ago may actually be a swarm of icy objects.
New Horizons project manager Glen Fountain, a veteran of nearly 50 years at the Johns Hopkins University Applied Physics Laboratory, told the Pluto probe’s team to live in the moment for Tuesday’s historic flyby, but look out for last-minute snags.
