My guest this week is Alex Haro, co-founder and CEO of Hubble Network, which is building a low Earth orbit satellite constellation that any Bluetooth chip can talk to directly, with nothing more than a software update. We get into how a Bluetooth "whisper" can be heard from orbit, Hubble's B2B model, early traction and the path to 60 satellites, use cases from asset and package tracking to livestock, wildfire detection and even butterflies, how Hubble compares with AirTags, privacy and unauthorized tracking, and the company's next milestones after its $200 million Series C. 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!
