Take a sneak peek at Pluto

NASA’s New Horizons probe has sent back its best view yet of Ultima Thule, taken just 6.5 minutes before closest approach on New Year’s Day.

Speeding through the outer solar system after a nine-year trek from Earth, NASA’s New Horizons spacecraft is awake and preparing for an encounter next summer with Pluto.

New Horizons science team members give personal accounts of their work during the Voyager Neptune encounter and their new assignments on the Pluto mission.
