Space-Grade Innovation: The Evolution of Onboard Computing With Aethero CEO Edward Ge Nov 25, 2025

Show notes

Computing capability has advanced rapidly on Earth, but on-board computing in space is more challenging — as chips have to be hardened to function amid the radiation environment in space. Edward Ge, co-founder and CEO of three-year old startup Aethero, is working to tackle this challenge and enable higher computing power onboard satellites.

In this On Orbit episode, Ed explains some of the challenges with space-based computing, and why there's the push to improve on-board processing to support missions like space missile defense, space domain awareness, rendezvous and proximity (RPO) operations and even future targets like orbital data centers. He sees the space industry in the midst of a transition where on-board processing will become the default, rather than the exception.

How Sovereign Networks Fit Into National Strategies With ST Engineering iDirect Nov 11, 2025

Show notes

While sovereign satcom systems are not a new idea, sovereignty has become a critical issue in the satellite industry over the last year as geopolitical trends push nations to want more control over their communications and space data. This episode of On Orbit features Keith Blanchet, vice president of Global Government for ST Engineering iDirect, to dig into this global trend.

Sovereignty can involve control over space and ground assets, spectrum, cryptography, and supply chains. Blanchet gives insight into the challenges that nations work through as they make decisions about sovereign networks like affordability, local expertise, and managing scope creep, and how commercial providers work closely to meet national needs. He also talks about how multi-orbit orchestration is playing a key role as nations look to build hybrid architectures and partner with their allies.

D2D and Defense Momentum: Takeaways from World Space Business Week Sep 30, 2025

Show notes

Back from Paris, Via Satellite Editor Mark Holmes joins On Orbit host Rachel Jewett to unpack some of the top takeaways from World Space Business Week. Two themes drove much of the conversation during the week — direct-to-device (D2D) and defense. Spectrum was a big topic of conversation with SpaceX's big spectrum buy and Viasat and Space42 unveiling a new shared spectrum approach to D2D. And while defense demand is not new, it's driving conversations from satellite connectivity, imagery, and manufacturing, as Europe in particular is working though what increased defense spending means for space capabilities.

Change was another theme this year with a new venue, and lots of new faces getting together to learn about the space and satellite industry. The editors cover some of the top storylines from the week, and their favorite parts of being in Paris in September.

Driving Commercial Integration in Space: Interview With COMSO Director Lt. Col. Tim Trimailo Aug 26, 2025

Show notes

The relationship between the commercial space industry and the Space Force has evolved in recent years. While the Space Force using commercial capabilities is not new, the "buy before build" philosophy has marked a change in acquisition strategy.

Space Systems Command's Commercial Space Office (COMSO) was set up two years ago to better integrate commercial capabilities. This week's On Orbit podcast episode features Lt. Col. Tim Trimailo, director of the Commercial Space Office. Trimailo took the helm of COMSO in April.

Trimailo says that while COMSO has spent time seeding the landscape of commercial capabilities, the focus is shifting to delivering operational capabilities to the warfighter. He also shares the latest on the Commercial Space Augmentation Reserve, the Proliferated Low Earth Orbit, or PLEO IDIQ contract, and takeaways from a recent wargame around space domain awareness.

This interview was part of the GovMilSpace Digital Series, a virtual event that brought together U.S. and allied space, defense, and intelligence leaders to address the evolving threats and priorities shaping tomorrow's missions. The series is available on-demand, with a panel discussion and video interviews featuring the Space Development Agency, UK Ministry of Defense, German BSI, and more. Registration is now open for GovMilSpace 2026, where these critical conversations continue in person during SATELLITE Week.
