NASA's Red Planet Rick this week on planetary radio.

Welcome, I'm Mat Kaplan of the Planetary Society, with more of the human adventure across our solar system and beyond.

Rick Davis is back.

I don't know anyone who has invested more time and sweat equity in getting humans to Mars.

He is the assistant director for science and exploration

in NASA's Science Mission Directorate.

But that only begins to tell you

about what he has done for the agency over many years.

He spent three of those years working at Star City in Russia to get American astronauts

into and back from space in Soyuz capsules.

And he was one of the very few international space station capcoms or capsule

communicators at the Johnson Space Center who was not an astronaut. He worked with

scores of astronauts during his time there and now among other things he co-leads

NASA's Mars Human Landing Sites Study.

Later Bruce Betts will join me for this week's What's Up and a brief light sale update.

I had just finished showing Rick Davis around Planetary Society headquarters, including our area devoted to the

Light Sale Project when we sat down for this great conversation.

Rick, welcome back to Planetary Radio and welcome to our headquarters here in Pasadena.

Matt it is wonderful to be here and an enormous congratulations to you guys on the successful mission and and doing some of the innovative stuff that you all have been doing, including

crowdsourcing.

It's really cool and you all should be incredibly proud of it.

Thank you, sir.
