- 32 minutes 15 secondsFrom cyberspace to space-cyber.
For years, in-space internet capabilities were rarely worth the hassle. Now, that’s changing.
In today’s episode, Maria Varmazis and Ethan Cook sit down to discuss how internet data moves through space systems and its recent advancements. For decades, GEO satellites made up most of the marketplace; however, LEO satellites are changing the landscape improving connectivity and speeds.

14 May 2026, 5:08 pm - 17 minutes 29 secondsRethinking industrial IoT from space.
This week on our Deep Space episode, Maria talks with Dave Roscoe, President of Satellite IoT for ORBCOMM and Skywave. They discuss the rollout of ORBCOMM’s latest purpose-built industrial satellite IoT network and what it signals for the future of mission-critical connectivity.
As satellite connectivity and device costs continue to decrease, organizations are rethinking where — and how — industrial IoT can be deployed across transportation, logistics, energy, maritime, agriculture, and remote infrastructure operations.

10 May 2026, 5:00 am - 22 minutes 7 secondsOrbital debris remediation as a stepping stone toward asteroid mining.
This week on our Deep Space episode, Maria speaks with TransAstra's CEO Joe Sercel about their recently demonstrated capture-bag technology aboard the ISS, drawing attention for its potential role in orbital debris cleanup. Debris removal is only the beginning. The real goal is far bigger: asteroid mining as future space infrastructure.
Sercel walks us through how the same capture system designed to safely enclose debris could eventually be used to secure near-Earth asteroids—unlocking access to water, propellant, and raw materials that enable sustained operations beyond Earth orbit.. Learn more about TransAstra's work.

29 April 2026, 5:00 am - 26 minutes 33 secondsEncore: The atmospheric impacts of satellite re-entry.
Please enjoy this encore while the team is out on vacation.
When satellites burn up upon re-entering Earth’s atmosphere, they release particles and gases, including metals like aluminium, which may affect atmospheric chemistry. This process, known as atmospheric ablation, is still poorly understood, but early evidence suggests metal content in the atmosphere is rising. To address these uncertainties, the UK Space Agency commissioned three targeted studies to investigate the potential impacts of satellite re-entry. We spoke to Professor Minkawn Kim from the University of Southampton about his findings.
You can hear the Professor’s chat with Maria from 2024 here.

5 April 2026, 5:00 am - 33 minutes 4 secondsA spaceport—and then some.
On this Deep Space episode, we share a conversation host Maria Varmazis had with Dr. Gabrielle Caswell at SpaceCom in January about Spaceport Australia, the spaceport that she owns, but if you can believe it, owning and running a spaceport is still barely scratching the surface of what she's working on. You can learn more on Gabrielle's website.
