Getting humans to Mars without breaking the bank 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. We can do it and we can do it affordably. That was the big question

being investigated at the Humans Orbiting Mars Workshop. We'll get a report this week from

Scott Hubbard, John Logston, and Bill Nye, the Science Guide. Bruce Betts and I give

two thumbs up to the Total Lunar Eclipse, complete with Blood Moon.

And we've got another eye telescope account and planetary radio

t-shirt for one of you.

Cassini has returned spectacular new images from Saturn and Emily Lockwala is here with more than a sneak

peak.

Emily, we go back out to Saturn this week to check in with

many of these. It's so exciting to see all these new images of moons come in and I can't

wait to get my hands on them to process them. And you know most of

Saturn's moons are sort of bright and white and gray so when you try to make color composites nothing terribly exciting happens, but the wonderful exception is IAPITUS which has this really dark leading hemisphere that's kind of reddish and then an

icy or trailing hemisphere and there's quite a sharp boundary in between them and so depending

on which face Cassini gets to look at, you can see these cool patterns all across IAPITES surface,

and it's just so fun to put the images together.

All right, now say something about this animation that you've created.

Well, Cassini takes lots of images in order to observe how the surface of a moon changes

with different illumination angle, but taking lots of images with a regular cadence means you can

also assemble them into an animation.
