  • Fascinating range of guests

    I am in the space industry and know some of the guests but something about the format facilitates more interesting discussions around not just the business of space but the things that inspired them to pursue a career in space. This often leads to broad discussions on the most exciting things, even the question of intelligent life existing elsewhere. (Spoiler alert it’s not so intelligent here!)

    Space is challenging but this podcast reminds me why it is also so much fun. Strongly recommend thi... more

  • Great podcast

    Interesting to listen to, great content, great guests. The audio isn’t great sometimes and jumps from loud to quiet, making it difficult to listen to sometimes. If you could correct that, I think this podcast could really grow a lot!

Talking Points

Recent interactions between the hosts and their guests.

#176 | Science Fiction | Mary Robinette Kowal
Q: What are some of the couple of pieces of advice you give aspiring writers, including science fiction writers who think about space novels?
Kowal advises writers to trust their taste as readers and develop the craft to match it. For space-based science fiction, she recommends reaching out to NASA and asking specialists interesting questions.
#176 | Science Fiction | Mary Robinette Kowal
Q: How do you go about hard science fiction? Do you do your own research? Do you consult space experts?
Kowal researches independently and consults subject-matter experts, including engineers and astronauts. She prioritizes getting the science right when it affects the plot or a problem characters must solve, while leaving some unresolved background details unexplained.
#174 | Persistent Imaging | Mark Keremedjiev, Orbital Sentry
Q: Why GEO instead of continuing with traditional LEO approaches?
GEO offers continuous coverage over a fixed region, dramatically increasing temporal resolution and enabling real-time monitoring that LEO cannot sustain without an impractical number of satellites and ground links.
#174 | Persistent Imaging | Mark Keremedjiev, Orbital Sentry
Q: What is the elevator pitch for Orbital Sentry?
Orbital Sentry aims to provide persistent imaging from geosynchronous orbit to 'live stream the Earth,' delivering continuous data over large regions to support wildfire monitoring, defense, and other commercial use cases.
#173 | Optical Communications | Rohit Jha, Transcelestial
Q: Rohit, can you summarize the core business lines and how they fit together for customers today?
Transcelestial currently operates three main lines: terrestrial laser communications linking cell towers for high-bandwidth urban networks, a defense/intelligence segment providing non-jammable links for sensitive operations, and a space-focused business developing inter-satellite and space-to-ground links, with a strategy to subsidize hardware to win customer adoption while monetizing bandwidth services. This creates a layered, scalable model from earth to space that builds toward a global optical network.
