Light sale, Triumphant, this week on Planetary Radio.

Welcome to the Travel Show that takes you to the Final Frontier.

I'm at Kaplan at the Planetary Society.

After taking the world and its technical team on an emotional roller coaster ride, the low-Earth

orbit test of a tiny Cubesat known as light sail was declared a success.

We'll listen to highlights of a press conference that included many of the major players

including Bill Nye.

Out at the other end of the show is Bruce Betts

with this week's What's Up segment. We begin with senior editor Emily Lockwala

who has a brand new and intriguing view of Pluto, the best ever seen by humans.

Closer and closer to Pluto, Emily, what is the news this week?

The news is that we really are seeing features on Pluto that we haven't seen with any instrument before.

And lo and behold, it's a line, it's a canally on Pluto.

Okay, now that's a pretty charged term. We don't want to make the mistake that Percival Lowell did.

No, that's right, you know, but I think it's really awesome that our images of Pluto that are beginning to come into focus are kind of recapitulating the history of

exploration of the planets.

When we first developed instruments that can see features on the surfaces of other worlds,

we didn't see them very well and they looked like lines to us and

and people even called them Canale and later on we found out that's not what they were

and it's happening again here with Pluto. We see the first feature you can spot on

new Horizons images of Pluto looks like a dark line across the surface. I think it's great, but as we get closer over the next month leading up to the flyby, we're going to see so much better.

Now tell me about this, you call him an image
