Tiny, far-flung Pluto is about to have a visitor — at least for a few hours.
On July 14, NASA’s New Horizons spacecraft will reach the dwarf planet and try to learn all it can about Pluto and its five known moons. Then the probe will leave Pluto behind, vanishing into the frigid darkness beyond the planets.
In its wake, New Horizons will introduce Earth to the last of the “classical planets.” Probes have flown past, orbited, crashed into or landed on every other world that orbits the sun. Now Pluto is getting its turn.
“This is the last picture show,” says Alan Stern, the mission’s leader. “It’s the capstone moment to the reconnaissance of the planets.”
