Momentus is one of still relatively few space companies listed on a stock exchange. Their offerings include satellites, hosted payload services, and last mile transportation for other people's satellites. CEO John Rood is our guest this week to tell us all about that, and also what it is like to be a publicly-listed space company. Enjoy!

Something a little different this week: a science fiction special! My guest is Mary Robinette Kowal, the Hugo and Nebula Award-winning author of the Lady Astronaut series and The Spare Man. We talk about getting the space science right in hard sci-fi, how AI, politics and spirituality show up (or don't) in science fiction, and how talking with her cat Elsie through word buttons has changed the way she thinks about first contact with aliens. Enjoy!

 Space lasers - we are talking about space lasers again -- for optical communications rather than more sinister purposes, at least for the moment. Our guest this week is Rohit Jha from Singapore-based startup Transcelestial. Optical communications are becoming an even bigger topic than they have been before, in part thanks to orbital data centers. We talk all about that, and much more, in the episode. Enjoy.

This week we’re talking about satellite navigation. All of us are using it every day mostly in its best-known form, GPS. Now there is a startup company trying to make satellite navigation much better. What that means, and how they’re doing it are among the topics I’m discussing with Brian Manning, CEO and co-founder of Xona Space Systems. Enjoy!
