| 0:02.0 | Hello and welcome to probably science. I'm your host, one of three in fact. I'm Jesse Case. I'm Andy Wood. I'm Matt Kirshan. We got a special guest. You might remember a couple of weeks ago on the podcast I was talking about the fact that I got shown around JPL, got a guided tour on account of having met a real proper scientist. |
| 0:29.4 | And JPL, for those not for our foreign listeners? |
| 0:33.0 | That is the Caltech slash NASA collaboration, the Jet Propulsion Laboratory. They have been responsible |
| 0:41.1 | for sending a bunch of spacecraft and satellites and Mars rovers and various other things |
| 0:47.9 | off the planet. They'll put it up there. They will do that. So our guest today is a |
| 0:53.6 | astrophysicist, is NASA's exoplanet science ambassador, is an employee of JPL and an all-round excellent human being. Please welcome to the show, Anjali Tripathi. How are you, Anjali? So good to be here, Matt. Thanks so much to all of you for having me. And it was great to host you at JPL last month. |

| 1:38.6 | And they're very proud of that. |
| 1:39.7 | And it's it's cool to be able to experience it and see what they're doing. |
| 1:44.2 | Right. |
| 1:44.7 | I mean, we get, what, thousands of visitors every year. |
| 1:49.0 | I think it's somewhere around 100,000 visitors every year. |
| 1:52.2 | And, you know, we have school groups, tours, right? |
| 1:54.4 | I think while you were there, Matt, you saw different groups, both of public and school, sort of waiting to get in at the visitors. |
