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.

A fresh image from NASA’s New Horizons spacecraft released Tuesday showed the mission’s distant flyby target a billion miles beyond Pluto — nicknamed Ultima Thule — has an elongated shape like that of a peanut shell or a bowling pin, and the prospect of higher-resolution pictures arriving on Earth later in the day had scientists salivating for more.
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.
