Apollo astronaut Al Warden, this week on planetary Radio. Radio. Welcome to the Travel Show that takes you to the Final Frontier.

I'm Matt Kaplan of the Planetary Society and I have a real treat for you this week.

Al Warden went to the moon 40 years ago.

Now he has written a book about that mission,

how a Michigan farm boy became an astronaut and what happened after Apollo 15.

We'll talk with him right where his command module was designed and built.

All the Let's go now to Emily Lachdwala, the Science and Technology Coordinator for the Planetary

Society and the editor of its blog. Emily, let's start today with the Image of the Week, and that

is this lovely thing that you've done of Hyperion. Yeah, Cassini flew past Hyperion recently and it was one of the closer

flybys it's had and produced some really gorgeous pictures and among them was this crescent view and Hyperion is so

lumpy that it doesn't really can't really call it a crescent actually it's just a

strange lumpy thing with lots of shadows and it was a pretty fun one to put

together. Beautiful image.

You also attended something with a really ugly name last week called S-BAG.

That's right.

There's all of these groups that NASA put together to bring scientists together to provide scientific input into NASA's future plans and they all have horrible sounding names like me PAG, Leag, Vexag, S-BAG, ipiWIG, they're really terrible.

And people insist on calling them by their acronyms.

Anyway, S-BAG is the Small Bodies Assessment Group.

It's the group that advises NASA on really quite a diversity of objects, everything from asteroids to the

Kuiper belt to Sentars and Trojans, and you know that includes everything from Pluto to

Series. And one of the things that was talked about a lot of course was all of the great new images from Vesta.

Is there some controversy there about these images?
