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.
Join us as The Planetary Society’s Mat Kaplan talks with New Horizons scientists and Pluto-watchers as we monitor the Applied Physics Lab’s live webcast, broadcast from Maryland. Visit the event page for details including a list of our special guests! Watch the webast here if you can't join us in person.

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.

Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
Pushing Back the Frontier: How The Planetary Society Helped Send a Spacecraft to Pluto
Posted by Jason Davis
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 is a Triumph for Space Advocates
Posted by Casey Dreier
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.
