Australia gets serious about space 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. The 68th International Astronautical Congress just

wrapped up in Adelaide Australia. We'll talk with Jason Davis about the revised

plans Elon Musk announced there for putting hundreds of people on Mars by the mid-2020s.

Then we'll talk with the man who headed the IAC effort.

Brett Bittington will also tell us about the Australian government's imminent creation of its first

National Space Agency.

Bruce Betts will tell us where and when we can chase the next decade or so's total eclipses

in this week's What's Up.

And he's got a really easy space trivia question for you this time.

Jason Davis is the Planetary Society's digital editor who follows space developments around the world.

the International Astronautical Congress last week.

Yeah, just put a big tower or flagpole on top of that or something.

An antenna maybe.

Okay, so I've already given away the code name for the rocket BFR, which we cannot actually

say on the radio.

Yeah, yeah, we'll call it the,

I hear some other people call it the big Falcon Rocket,
