Lou Friedman at the 100-year Starship Symposium this week on planetary radio. Radio. Welcome to the travel show that takes you to the Final Frontier.

I'm Matt Kaplan of the Planetary Society. We'll talk with my old boss about this latest gathering

to consider our future among the stars. Lou doubts it will happen soon, at least with humans

on board, Bill Nye is back with his thoughts about a recent

Space News op-ed piece.

And in 20 minutes or so, Bruce Betts and I will announce the five winners of our latest

contest that came from outer space.

We begin as we should with the planetary societies Emily Loch Duwala.

It had a large copper impactor that had slammed into Comet Temple 1

to watch the spray of debris.

The spacecraft really went far above and beyond its original designed mission.

And went on to another mission as well.

Can you say a word or two about that?

Yeah, it actually had a couple of extended missions. One of them was to use, take advantage of a blur in its main camera to look at some follow-up studies of extra solar planets. And while it was doing that mission, it actually turned back and looked at Earth, treating Earth as an exoplanet and watching the moon transit in a really cool series of photos.

And then it performed another comet flyby, passing by Comet Hartley too and getting some really cool pictures

of this dogbone shaped comet.

And through it all, it was a real small spacecraft
