Come with me to the bottom of the sea this week on planetary radio.

Welcome to the travel show that takes you to the final frontier.

I'm at Kaplan of the Planetary Society. the an undersea adventure in preparation for the exploration of Mars and other

destinations in our solar system. We'll talk with engineer David Cohen as he was in

the middle of spending two weeks with three astronauts and others 62 feet below the ocean

surface. Casey dryer drops in with a space advocacy update while Bruce Betts will

have his own underwater encounter in this week's

what's up. We begin with the Planetary Society's senior editor Emily Lachowala.

Emily this is a little different from what we normally talk about about a visit that you made

some work you did volunteer work for your daughter's school library and I want to say

first of all I think they were lucky to have a school library that had six or more feet of planetary science books.

It is a fantastic public school library and I'm very grateful for that.

I will say that at least a foot, maybe two, are due to me donating them all of my extra

copies of review books. They are lucky people. What did they ask you to do?

The librarian asked me to go through the shelf and check to see if there were books that shouldn't be there either

because they were just bad or because they were woefully outdated.

And I know that a lot of people kind of winced on Twitter when I talked about getting

rid of books from a library. But children's books of those books get outdated then you really need to replace them with more recent books.

What were the results of your search?

Well it was kind of interesting. It sort of depended upon the planet which books seemed

more out of date than others. The Moon was a really interesting case because a lot of the books

they didn't incorporate modern discoveries with the most recent orbiters, but that wasn't really the focus of the book anyway.
