Planet 9 from Outer Space, this week on planetary radio.

Welcome to the Travel Show that takes you to the final frontier. I'm

at Kaplan of the Planetary Society. What a show we have for you this week,

headlined by a conversation with Mike Brown and Constantine Batigin, the guys who have pointed the way

to what is likely our solar system's ninth planet, one that won't get demoted.

The world has beat a path to Emily Lockawala's door for a look at

spectacular images from China's moonlander and rover.

Bilnai is making waves, gravity waves, and he'll salute another fallen Apollo hero.

Lots of surprises from our What's Up segment,

including the first talking answer to the space trivia contest.

Here's the Planetary Society's senior editor.

Emily, you've as usual, got lots for us to look at in the blog at planetary.org, but I'm

going to stretch back a couple of weeks to a piece you posted about a certain Chinese lunar mission which has

attracted an enormous amount of attention. Tell us about this.

Yeah, well a Chinese researcher alerted me to the fact that some data had been released from the Chang'a 3 mission.

This was the Lander Mission with the U-2 rover.

I had not known of any release of science data before. They'd release lots of photos from the mission, but this was an actual science data release with like all of the images from a certain stretch of time, with all the metadata and other header information that you need in order to figure out how to assemble all the images together.

It was really awesome.

And so I did what I usually do, which is to download a whole lot of data and try to understand it and

I made a browse page to it. But then I realized that there's a lot of American researchers who are permitted to access Chinese servers for data.

And so I thought, what if I provided a public service by hosting all of the original data on the Planetary Society's data server and allowing people

to download it from there and people seem to like that.
