Urgent: We have become aware that a fraudulent LinkedIn account is demanding payment in exchange for “consideration” for a role by impersonating one of our employees. We have also learned that the impersonators are creating fake employee profiles and posing as CesiumAstro recruiters to contact potential applicants. CesiumAstro will never ask for payment to be considered for employment. Further, our employees or representatives will never request payment at any point in the hiring process. Any communication requesting payment in connection with a job at CesiumAstro is fraudulent, and you should not comply. If you receive such a message: -Do not respond or send any money. -Report the impersonator or fake profile on LinkedIn by selecting More, then --Report/Block, then “This person is impersonating someone.” -Document the communication, including screenshots, URLs, and message text. CesiumAstro takes misuse of its name, brand, and employee identities very seriously. Please stay vigilant, verify any communication related to hiring, and contact the company directly through our official careers page if you have questions or concerns. Thank you.

One of the ironies of our space industry is that spacecraft and launch have advanced. But the comms systems they rely on have lagged behind. These systems were built in a Cold War era that prioritized stability above all else. They were large, hardware-defined, and designed to last 20–30 years — often at the expense of adaptability, flexibility, and speed. In defense, that meant satellites delivering 10- to 20-year-old technology to warfighters operating in fast-changing environments. In commercial markets, it meant systems built for broadcast television, not for mobile data, autonomous vehicles, or distributed AI. That might have made sense at the time. But it doesn’t anymore. Today’s missions (military or commercial) demand: 1 / Real-time, high-throughput, resilient communications 2 / Beam agility, multi-orbit access, software-defined reconfiguration 3 / Systems that can evolve in orbit, not sit frozen in time CesiumAstro (Per Aspera Founding Sponsor 🇺🇸💥) rebuilt space communications from first principles. They started with the core constraint: how to move information through space — quickly, intelligently, and adaptively. From that, they built: 1 / Modular, steerable phased arrays 2 / A digital backplane tuned for routing and signal processing 3 / Flight systems designed for real-time responsiveness 4 / And now, their own fully integrated LEO spacecraft, Element — architected entirely around the communications system itself This is a foundational breakthrough: turning space-based communications from rigid hardware into responsive, reprogrammable infrastructure for our intelligent systems of the future. Really excited for a CesiumAstro future! 👇 Check out the Per Aspera x CesiumAstro teardown below. P.S. CEO Shey Sabripour had this idea in the early 2000s while still at Lockheed Martin. That’s a visionary, I love Shey!

It was an honor to join the “New Industrial Strategies Redefining the Ecosystem” panel at #WSBW. Thank you to Carla Filotico and my fellow panelists for a thoughtful discussion on commercialization, software-defined systems, dual-use platforms, and the realities of today’s geopolitical landscape. At CesiumAstro, we’re focused on delivering full-stack communication solutions for commercial and defense missions. I am confident in the progress our industry will achieve together in the years ahead. Tom Campbell Giulio Ranzo Jean-Marie Bétermier Vincent Dedieu Lisa Napolitano

Go ahead. Tell the industry leader in phased array payloads that bus integration isn’t hard. Built for modularity and scalability, our highest-power-in-class Element satellite accelerates time to orbit by launching fully integrated—optimized for today and equipped with software-defined flexibility and abundant processing power for tomorrow. At CesiumAstro, payloads aren’t an afterthought—they’re the foundation. That’s why Element has never spent a day without advanced communications solutions at its core. From modules to systems to satellites, we're delivering the future of space connectivity. Email us to find out more: Info@CesiumAstro.com

We’re bringing CesiumAstro to Paris for World Space Business Week, September 15-19. Join Founder & CEO Shey Sabripour, Senior Director of BD Iraklis Hatziathanasiou, and Product Manager Sotiria Stathopoulou to discuss how multi-beam Ka-band payloads, the Element satellite, and Skylark SATCOM terminals are reshaping flexible, high-capacity connectivity. Book a meeting: Info@CesiumAstro.com #WSBW2025 #SpaceConnectivity #SatelliteCommunications

Demand for CesiumAstro’s connectivity ecosystem is growing . . . and so are we. Our #Westminster, #Colorado, facility has expanded again to scale delivery across the stack: Satellites. SATCOM terminals. Phased arrays. All built in-house. Software, hardware, test, and manufacturing under one roof. We’re building real products, for real missions, and shipping today.
