A gigantic new eye on the universe this week on planetary radio. Hi everyone, welcome to Public Radio's travel show that takes you to the final frontier.

I'm Matt Kaplan of the Planetary Society and happy birthday to us.

We're celebrating the sixth anniversary of this little show about the biggest possible

subject. Thanks for joining us on our weekly ride across the Cosmos.

about plans for the 30-meter telescope,

an instrument that will let us explore farther than ever before.

Emily Lachihuahua will help us party by resolving a long disputed question about the

Voyager 1 mission, and Bruce Bats will join me to announce the winners of our sixth

anniversary slogan contest as he points out the most interesting points of light in

our night sky. Space Shuttle endeavor rattled windows in Southern California Sunday afternoon

States seem prudent.

For other space news and big news at that, we turn to Bill Nye.

I'll be right back with Richard Ellis.

Hey, hey Bill Nye, the planetary guy here, Vice President of Planetary Society.

And this week on Mars, we may have made the biggest discovery of our lifetimes.

I know we haven't talked about it too much around the world, but we have discovered

glaciers, enormous ice rinks of ice on Mars.

And the reason we didn't see them before is there under sand or gravel or rocky debris and you don't see them in photographs but with an Italian built radar on board the US-built Mars Reconnaissance Orbiter,

we found ice, enormous amounts of it, at 29 degrees south latitude on Mars.

That's almost in the tropics of Mars,
