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.

Three months ago, I posted an article explaining what to expect during the flyby. This is a revised version of the same post, with some errors corrected, the expected sizes of Nix and Hydra updated, and times of press briefings added.
ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.
The month of September begins with an annular solar eclipse visible from much of Africa on September 1. On or after September 8, we'll see OSIRIS-REx launch into a two-year cruise toward a rendezvous with asteroid Bennu. But September will close, sadly, with the end of the wonderful Rosetta mission.
This month we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress toward its September 8 launch. Both rovers are road-tripping at Mars, while ExoMars Trace Gas Orbiter has completed a major mid-course correction ahead of its October arrival.
Mission History & Advocacy

It took 16 years and five spacecraft designs to get a mission to Pluto. The Planetary Society was there through it all, always striving to help NASA push back our solar system's frontier.

New Horizons—what will be NASA’s greatest success of 2015—was cancelled multiple times in its early life, and many times before that in its previous incarnations. A mission to Pluto was not inevitable, despite the overwhelming scientific and public excitement.
