Welcome everyone to the November Space Policy Edition of Planetary Radio.

0:19.4

We are very happy to have you on board again and we have a terrific conversation to share

0:24.9

with you. One that my colleague Casey Dreyer, our senior Space Policy Advisor at the Planetary

0:32.0

Society, also a chief advocate, has had with someone who has been kind of a regular on

0:38.4

Planetary Radio. First though, Casey, welcome back.

0:41.6

Thanks, Matt. I assume you're referring to Lindley Johnson, the impactful discussion that

0:45.6

we had about the upcoming, for us as we record this, launch of Dart, which will be the first

0:51.9

in-space test of asteroid deflection technology. I think there is a really wonderful and interesting

0:58.3

story there about how we are maturing this whole area of planetary defense from ground-based

1:05.6

observations now to in-space demonstrations and going forward into a permanent flight program,

1:12.3

four missions that aren't primarily about science or human spaceflight, but primarily about

1:17.0

defending the Earth from large impacts. So this program has just changed enormously over the

1:22.5

last 20 years and Lindley has been there pretty much every step of the way in the NASA side,

1:26.7

and we walk through how that has changed, why it changed, and then what to expect going forward.

1:31.8

It's a terrific conversation. As usual, I have been able to go through it and so I highly recommend

1:37.8

sticking around for this. It definitely covers some ground that we have not covered with Lindley

1:42.7

before on planetary radio. Here is a program note I expect that in the weekly planetary radio,

1:51.6

we're going to welcome back Nancy Shabo and possibly some other people who are directly involved

1:57.2

with the Dart mission. Nancy, of course, is the coordination lead at the applied physics lab,

2:04.9

which is the lead agency for development of Dart, and I'm looking forward to welcoming

2:10.0

her back for the beginning of this very, very important mission for those of us who deeply

2:16.4

care about planetary defense. We know that that includes a lot of you out there, especially those
