The Dunes of Titan and the Air of Other Worlds, this week on Planetary Radio.

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

solar system and beyond.

I've enjoyed every interview I've done for this show.

Some of them run long. It always makes me uneasy when an

episode approaches the hour mark because your time is valuable. But now and

then there's a conversation that makes a longer visit seem just right.

That's the case this week with Johns Hopkins University

planetary scientist Sarah Horst.

Let me know if you agree.

How does caffeine in space come up while talking to both Sarah and

to Planetary Society Chief Scientist Bruce Betts? Stay with us and you'll find out.

First up a report from our senior editor Emily

Lochuwala who just got back from a big meeting in Texas. The Lunar and

Planetary Science Conference, it's one of your favorite stops every year, isn't it, Emily?

It absolutely is. I've been going for 20 years now.

Almost every year, I see all my friends from grad school and ever since we catch up on our

families and on great science. It's just a fun meeting.

We're going to put a link up to the conference looking back at the conference

partly just because the photos are so great.

It looks like everybody was having such a good time.

Everybody has a great time when they get together
