0:00.0	We're celebrating the 10-year anniversary of the New Horizons flyby of Pluto, this week on Planetary Radio.
0:10.0	I'm Sarah Al-Ahmed of the Planetary Society, with more of the human adventure across our solar system and beyond. A decade ago, NASA's New Horizon spacecraft flew past Pluto and revealed a world that was

0:29.6	This week, we're looking back and forward with Ellen Stern, the principal investigator behind the mission.
0:35.6	Then we'll check in with a Dean Denton, NASA postdoctoral program fellow at the Southwest Research Institute.
0:42.5	She's fresh from the anniversary conference at the Johns Hopkins Applied Physics Lab.
0:47.1	We'll hear all about the fresh science that's still coming out of that data.
0:50.7	Our own Jack Corelli, Director of Government Relations at the Planetary Society, joins us with an update on the latest space advocacy developments.
0:58.3	Good news, everyone, but also much work still to do.
1:02.5	We'll let you know how you can help protect missions like New Horizons from premature shutdown.
1:07.2	And finally, we'll close out with What's Up with Bruce Betts, our chief scientist, as we talk a little bit about Arakoth, the furthest object in our solar system that we've ever observed up close, thanks to New Horizons.

2:03.6	saved NASA science campaign, which is helping to protect missions like New Horizons and keep the
2:08.6	spirit of exploration alive in the United States. It took nearly 20 years of relentless advocacy
2:16.1	to make it happen. But on January 19, 2006, NASA's New
