We've got a free astronomy class and an unconference for you this week on planetary Radio. Radio. Welcome to the Travel Show that takes you to the Final Frontier.

I'm Matt Kaplan of the Planetary Society.

A double-headed today as we visit with planners of the third annual Space Up Unconference in

San Diego.

They'd love for you to attend, but they are also making it easier for you to find a space up gathering near you

or to start your own.

Don't know what an unconference is, you will in a few minutes.

Then we'll find out how we will soon be able to participate in a 14-week online

intro to astronomy course taught by our own Bruce Betts. You know him as my partner in the

what's up segment that closes every episode of planetary

radio and you may also know that he is the planetary society's director of

projects but Dr Betts is also very much a Caltech trained astronomer and planetary scientist and he'll be sharing

his love of the solar system and beyond with anyone who wants to watch.

Bill Nye will also drop by to tell us a story about Stephen Hawking.

Emily Lautuala is ready right now to take us back to the earliest days of a pioneering

mission to Jupiter.

Emily, I think we should talk this week about a terrific find that takes us back to a mission that really succeeded reading this stuff

it seems in spite of itself. Yeah we're talking about the Galileo Mission to Jupiter that these newsletters that

were unearthed by Patrick Wiggins, who scanned them for me, covered a period from 1981 to

1997. It's kind of hard to believe that 1981 is more than 30 years ago now,

which was the time it took to get Galileo from the drawing board to launch,

which is just an incredible period of time.
