Neil Tyson and more at a 35th anniversary party 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. The Society was turning 35 and we wanted to party

with 3,000 of our best friends. You'll hear just a few minutes of that celebration on today's special show.

First though we'll check in with Jason Davis and Casey Dreyer. They participated in

NASA's just completed first landing site workshop for human missions to the surface of Mars.

We'll hear their report right after this week's visit with senior editor Emily Lock-Dwalla.

Emily, you do a lot of speaking all over the place nowadays,

Tell us about it.

Yeah, we were approached by an organization called the California

Map Society and I thought that was a cool opportunity to deliver a new talk

because maps are really what got me into geology in the first place. I love geologic maps. I love the idea of mapping and

naming new territory across all of these solar system worlds. And so I thought it would be cool to give

a talk to this organization. What did you talk about? I mean just that we have lots of places to map.

I did mention that but I thought it would be interesting to talk about how we go about generating new maps of new worlds and how you have to begin with a fly-by mission that tells you something

about what the surface of the world looks like but generally gives you only a very incomplete view of the world.

And then you go back with orbital missions

and you build up different kinds of maps,

photo maps, topographic maps,

mineral composition maps,
