A astronomy cast, episode 608, Perseverance Rover, 100 Days in Rolling.

Welcome to Astronomy Cast, a weekly fax-based journey through the Cosmos where we help you

understand not only what we know, but how we know what we know.

I'm Fraser Kane, publisher of University Day with me is Dr. Pam LaGay, a senior scientist

for the Planetary Sciences Institute and the Director of Cosmos Quest.

Hey, Pamela, how you doing?

I'm doing well. We didn't get hit by tornadoes yesterday, which is always a plus.

So far. Well, yesterday is past, so I feel safe saying yesterday we did not get hit by tornadoes.

Right. And spring is here, the yard is a flower with weeds,

which is not one bit. So yeah, but I didn't do anything, which was nice.

Monday. I took the whole thing off, which was great. So I was rested and relaxed, and I'm ready

to talk science. Good. Now, as you all know, Pamela refuses to talk about any missions, which

aren't actually doing science. Well, perseveres has crossed the line from fantasy to an actual

working rover, scooping regolith and yeating helicopters. What has the rover accomplished in

its first 100 days? I had a teenage daughter. I understand the terminology. I'm with it.

Incorrect. Do I have to just say yeat? No, yeating.

No, yeating. It's it you're conjugating it correctly. It is a glorious concept, and it is

exactly what this little rover has done. It didn't. It did. It did.
