A volcano in frigid Antarctica and a tribute to the last man to walk on the moon this week on planetary radio.

Welcome, I'm Matt Kaplan, of the Planetary Society with more of the human adventure across our solar

system and beyond.

Intrepid explorers Rosalie Lopez and Michael Carroll return with the tale of their just completed trip

to the bottom of our planet.

Wait will you hear about their adventure

and what it means for our knowledge of other worlds.

The Planetary Society's light sale is on display in

London. Bill Nye will tell you where to find it, and you'll find out what 283 Octillion

Earths have to do with this week's space trivia contest answer when I'm joined

by Bruce Betts for What's Up?

Emily Lochuwala is the Planetary Society's senior editor.

Emily, you posted a couple of absolutely stunning, gorgeous images from Saturn on the 19th, January

19th.

Tell us about these.

These are some images that Cassini took recently shortly after changing its orbit to one where the

paryapses passes right between the F-ring and the G-ring, and what that means is that they get a lot closer to the rings and to the

moons that are embedded in the rings and so they're getting these amazing views

of the weird little moons that are embedded in the rings and also of just

striking structure within the rings themselves.

Stanley Kubrick just called from Beyond the Grave.

He wants to know if you can use these in the remake of the 2001 Space Odyssey trip sequence.
