My guest this week, Karthik Gollapudi, led the software team for SpaceX’s Dragon capsule. In this role, he realized the importance of monitoring complex hardware systems in order to detect faults or ideally prevent them before they even happen. That led him to become co-founder and CEO of Sift, a venture-funded startup dedicated to monitoring and analyzing hardware telemetry, and Sift is the topic of this week’s podcast. Enjoy!

Spaceports should become a bigger business going forward if all goes well in the space sector and we will have ever more rockets launching from ever more locations. This is why some private companies are now getting into this market. One of them is Maritime Launch from Canada, who are developing a spaceport in Novia Scotia. My guest this week, Founder & CEO Stephen Matier, will tell us all about what it takes to build a spaceport, operate it, and much more. Enjoy!

A City on Mars: Can we settle space, should we settle space, and have we really thought this through? – That is the title of a book published in late 2023 which then became an instant NY Times bestseller and went on to win a 2024 Hugo Award. My guest this week is Kelly Weinersmith, one of its two authors, together with her husband. The book is a critical, and humorously written, examination of the question of whether humanity should settle space. It touches on everything ranging from legal aspects all the way to having babies in Space. For me as a die-hard proponent of humanity settling in space, this was a fun and insightful conversation to have. I’m sure you’ll enjoy it, too!
