T-Minus: Space-Cyber Briefing

Latest Episodes:

From cyberspace to space-cyber. May 17, 2026

Show notes

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.

Rethinking industrial IoT from space. May 10, 2026

Show notes

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.

Orbital debris remediation as a stepping stone toward asteroid mining. May 03, 2026

Show notes

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.

Encore: The atmospheric impacts of satellite re-entry. Apr 26, 2026

Show notes

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.
