How will get humans to Mars this week on planetary radio?

Welcome to the travel show that takes you to the Final Frontier. I'm

Matt Kaplan of the Planetary Society. Three of NASA's top aces will tell us

about the tremendous challenges we face and the steady progress were making toward

footprints on the red planet. Bill Nye and Bruce Betts also check in and

senior editor Emily Lacowala is right around the corner.

Did you notice?

That's the gorgeous new arrangement of our theme you hear in the background.

You online listeners will be treated to the entire tune at the end of today's show. Here's Emily.

Emily this week you've got at least a couple of blog entries to look at from the 25th

and the 26th of May. Both images taken by folks that you've been in contact with. I'm most

interested in this one from the 25th where you actually asked somebody to

take a look at something something old. I had been using in a talk an example of a somewhat garishly colored

official release of an image of Saturn from the Voyager missions and I wanted to compare and

contrast it with what it would look like if you were actually there.

So I asked one of my image processing friends Ian Regan to take a look at that data set and he found a really nice one with the whole globe of Saturn tilted with several of its icy moons

poised in front of it. It's just very pretty. And it's accompanied by some images of

the moon Ganymede. Yeah actually that was the trigger for this post was this amazing new color global

portrait of Ganymede put together by Bjorn Johnson. He's been working on it

for quite some time. The problem with this one was that it was color, it was global, but several of the frames for the

image were smeared and that was giving him a very difficult time trying to put

it together into a full global view, it's something nobody has ever managed to do
