Scientists and Hubble Space Telescope Repairman John Grunsfeld, 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.

Five space shuttle missions, three of which were devoted to fixing or upgrading the Hubble,

Chief Scientist of NASA, and then Associate Administrator of the Agency's Science Mission Directorate.

That's John Grunsfeld, and now he is the newest member of the Planetary Society's Board of Directors.

We'll sit down with John for an uplifting, revealing, and personal conversation about his travels,

his passion for space and science, and where he thinks we are headed.

We'll also head over to a special screening of the new and terrific documentary about Opportunity, the Mars Exploration Rover,

and the wonderful team that made it such a success.

Sarah Alamed is moments away from joining me and attribute to Apollo 17 the last Apollo mission to the moon that has just reached its 50th anniversary.

We'll close with a visit to Ancient Greece, where Planetary Society Chief Scientist Bruce Betts will reveal the mother of Artemis,

sister of Apollo, and namesake for the mission that is headed back from circling the moon as this week's show is published.

If all goes well, the uncrewed Artemis I mission will splash down off the coast of my hometown, San Diego, on December 11.

You can read more about Artemis in the December 2nd edition of our free weekly newsletter, the downlink,

it's at planetary.org where you'll also find the winners of our Best of 2022 campaign.

You chose them, now you can see and help us celebrate the year's greatest accomplishments in space.

Sarah Alamed is now less than a month from becoming the new host of this show.

She is finishing up her work as the Planetary Society's digital community manager.

Sarah, welcome back again, as people hear this show, at least as it is published.

We are celebrating, maybe lamenting a little bit, the very last of the Apollo missions that made it to the moon and put humans up there on the surface.

Apollo 17, as we speak, they were on their way to the moon 50 years ago today.

Yeah, it's weird to really grok the fact that it's been 50 years since humans walked around on the moon.
