Rocketing into the Aurora this week on planetary Radio. Radio. Welcome to the Travel Show that takes you to the Final Frontier.

I'm at Kaplan of the Planetary Society, back with more for my recent trip to Alaska.

This time we'll visit with Neil Brown at the poker flat research range near Fairbanks.

He ran this sounding rocket launch facility for 18 years.

Join us for a tour.

Meanwhile, Bill Nye will give us an update on NASA's planetary science budget,

and later Bruce Betts gets us ready for an exciting eclipse that is just days away.

We begin with Senior Editor Emily Lachto-Wala.

Emily, we're looking way way out there, still in our solar solar system but a long ways from Earth.

That's right there's a whole lot of news about the most distant reaches of the solar

system in the last week.

Start us off with what first showed up in the blog as your March 26th entry titled A Second Sedna.

What does it mean?

Well, what does it mean?

Yeah, well, when astronomers first discovered Sedna now Mike Brown discovered it, it immediately

posed a whole lot of questions about the whole structure of the solar system, because here

was a world that we kind of tend to think of all of those things that are beyond Neptune as just being beyond Neptune, but there's different classes of things.

Most of them have orbits that eventually bring them back to Neptune's orbit, which tells you that it's Neptune that put them on these scattered orbits in the first place,

encounters with giant planets that gave them the current distant orbits that they have,

but they all come back to Neptune's neighborhood sooner or later.

Sedna doesn't do that.

And so Sedna hinted at part of the
