Ice Giants with Zivi Turtle this week on planetary radio.

Welcome to the travel show that takes you to the final frontier.

I'm at Kaplan to the final frontier.

I'm Matt Kaplan of a planetary society.

Planetary scientist Elizabeth Zivi Turtle wants a mission to Uranus or Neptune.

She'll tell us about good news from NASA in a few minutes. Have you read the Martian?

Bill Nye has and he'll tell us why it's so much fun. And Bruce Batts will prepare us for a

lunar eclipse. First though we'll talk with senior editor Emily

Lochuwala about her latest update on the Curiosity rover now rolling across a red

planet near you. Emily love this new curiosity update.

Obviously time to dig out the red blue 3D glasses.

Yeah, it's always fun to dig into the 3D data captured by the high-rise camera on Mars

reconnaissance orbiter to get a sense of the

landscape that curiosity is driving through and it's getting much more

interesting. There's ridges and valleys and sand dunes and the mountains getting

closer and it's pretty fun. Why is this looking for the next drill site proving to be more challenging than was originally

thought?

Well it has to do with trying to find a place to drill where the scientists are sure that they really understand the scientific context.

And context is really what it's all about if what you want to do is tell a story.

They have already drilled a couple times in this mudstone layer called the Murray Formation and now they're

interested in drilling into the next rock type that's sitting on top of it called the Stimson, which is an

eolian sandstone, a wind-blown sandstone. But they've had a hard time finding a good place to
