0:00.0 | Celebrating asteroid day with Dante Loretta this week on planetary radio. |
0:07.0 | Welcome to the Travel Show that takes you to the final frontier. I'm |
0:14.8 | Mac Kaplan of the Planetary Society. Very soon a spacecraft named |
0:19.5 | Osiris Rex will depart on its mission to an asteroid named Benu. |
0:25.1 | The leader of that mission returns to our show with an update and an eloquent explanation |
0:30.0 | of why we need to learn more about these small companions in our solar system. |

1:21.0 | It's got to be nerve-wracking for the people who are going to be at JPL, |
1:25.4 | and I know that you'll be there among them. |
1:27.5 | It really is, made all the more so by the fact that nobody that you'll see in mission control |
1:31.8 | on the day of orbit insertion will actually be able to do anything |
