New Horizons at the Pluto System

For the first time in history, Pluto will be seen up close as NASA's New Horizons mission makes a historic flyby of the dwarf planet. It has taken ten years for the New Horizons spacecraft to reach Pluto, and several years of advocacy beforehand to make the mission a reality. The Planetary Society's support for a mission to Pluto began 25 years ago and today stands as a shining example of the possibilities when the world's citizens are empowered to advocate for space exploration.

The month of September begins with an annular solar eclipse visible from much of Africa on September 1.
