Emily Lackawala and the last orbits of Cassini this week on planetary radio.

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

Less than two months now till the Cassini spacecraft ends its nearly 20 years at Saturn by plunging down into that ringed world.

My colleague Emily Lockwala is back with a preview of what to expect as the school bus-sized robot grazes the planet

passing inside its magnificent rings.

Bruce Betts puts on his best shatner for this week's random space fact. Lucky for him, we pay him to do science and projects, not impressions.

But he'll still give you another chance to win the new planetary radio t-shirt

and a pair of eclipse glasses.

Up first is the CEO of the Planetary Society, Bill Nye, the very

much a science guy. Bill, we missed you last week because you were on the road promoting

your brand new book. Tell us about that and I suspect it has a space angle.

Yes, everything all at once, how nerds solve problems.

Yes, everyone, there's 20 in a carton, they make great gifts.

No, it's everybody, this is something near and dear to me. I was, I've been a nerd since I was in high school I've been fascinated with how things work and everybody is passionate about something that everybody's got something they want to accomplish they want to do and they want to do.

And I just encourage everybody to unleash that,

to embrace that about yourself and do something cool

to leave the world better than you found it.

So along this line, you know, there's three things that I think

we want for everyone on earth. We want clean water, renewably produced reliable electricity,

and access to the internet. Now to provide access to the internet or

whatever the future of electronic information is called, we're almost

certainly going to have to have space assets. These will be satellites in low Earth
