A visit with former NASA Chief Scientist Jim Greene 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.

Jim Greene headed NASA's Planetary Science Division for an unprecedented 12 years before

becoming the agency's chief scientist.

He has returned to tell us about a recent workshop that considered doing big science from

the moon, but Jim and I will mostly look back across his rich and fascinating career.

You're in for some great stories.

I'll get to space headlines from the downlink in a couple of minutes.

First though, I have something to share with you.

Here's how I express it in a message we've posted for all to see at Planetary.org.

I had been working at the Planetary Society for two years when co-founder and executive

director Lewis Friedman gave me the thumbs up.

It was only a few weeks later that Planetary Radio premiered.

Lewis was my first guest on that November 25, 2002 episode.

It also featured what would become a regular visit with our former colleague Emily Lock-Dawala.

We closed the show as we have now ended over 1,000 episodes with what's up.

My friend Bruce Betz told us what to look for in the night sky, looked back across the

history of space exploration, provided a reverberating random space fact, and offered

an entertaining space trivia contest challenge.

That show could only be heard on a single radio station and our primitive website.
