The 6 Layers of Space Internet Infrastructure

It’s no longer a thing of the future: space internet infrastructure is being developed today - and is already facing high demand. A single ground network provider is handling more than 5,500 satellite contacts a day, orbital data center operators are running production workloads in space, and optical mesh

SpaceComputer Mid-Year Updates 2026: Building the Fabric of the Space Internet

On June 12th 2026, SpaceX completed the largest initial public offering in history, entering the public markets at a valuation approaching $1.8 trillion. This historic IPO alone has lowered the barrier of capital inflows into the space industry significantly. We are about to enter a major space acceleration era!

What Is Big Tech's Role in Space Exploration? What is big tech's role in space exploration? In short: big tech supplies the infrastructure layer. Google, Amazon, Microsoft, and Nvidia leave the rockets to launch providers and bring connectivity, cloud services, chips, and capital to orbit instead,

SpaceComputer Partners with Tropic Square: Open Security Hardware for Orbital Compute

We’re thrilled to announce that SpaceComputer and Tropic Square are entering a partnership. Tropic Square is a Prague-based semiconductor firm building the world's first open-source, auditable secure element (SE). Tropic Square's TROPIC01 chip is being integrated into our Space Fabric hardware design as

Filip Rezabek on Quantum Communications at SmallSat Europe

I'm Filip, one of the co-founders and CTO of SpaceComputer. And today I'll be talking about quantum communications. So it's a short overview of actually where we see the space heading with respect to quantum computing and how can we actually prepare for

In our previous post, we outlined the randomness supply chain and how we can ensure randomness is correctly generated and delivered to the user. But once the user has that randomness, along with proof that it hasn't been tampered with, how does he use it? That’s the

What Is Post-Quantum Cryptography? Defense Against Quantum Threats

Adversaries are harvesting encrypted data today. They cannot read it yet, but they are storing it and waiting for the day there's quantum computers powerful enough to break current encryption standards in hours. This is the "Harvest Now, Decrypt Later" threat, and it is already underway.

Ground Station Cybersecurity: Why Your Satellite's Biggest Risk Is on the Ground

When it comes to satellite security, it’s a lot easier to attack when your target is on the ground rather than in orbit. Ground station cybersecurity, the practice of protecting the antennas, control centers, and software that command satellites and receive their data, is where many incidents begin. A

What Is a Signing Key? Key Generation in Low Earth Orbit

What Is a Signing Key? Before you trust any secure system, you need to trust one secret: its signing key. If an attacker copies that key, they can impersonate the system it belongs to, and without other mechanisms in place, nobody downstream can tell. For any company evaluating where to

4 Hardware Components Behind SpaceComputer's Satellite Architecture

By 2027, several orbital compute platforms will be live. Most will depend on their single compute chip vendor never being compromised. Once a satellite is in orbit, that dependency is permanent. The hardware choices made before launch determine whether the system can be trusted, as there is no way to

Making Orbitport Verifiable: Reproducible Builds, Docker Hardened Images, and Attested TLS

Introduction In our previous post, Orbitport: The Gateway to Space, we introduced Orbitport as SpaceComputer’s universal gateway between Earth and in-space infrastructure: a developer-friendly API layer that abstracts away ground-station scheduling, intermittent orbital connectivity, satellite-specific integrations, and the operational complexity of communicating with hardware in

Space Fabric: What you need to know

We are building the standard hardware and software architecture for computing and the space internet in orbit. Every secure computing chip protecting financial transactions, cloud workloads, and government data today has the same vulnerability: it can be physically accessed on Earth. Given enough time and physical access, an attacker can

Why Use Proof of Execution Triangulation for Space Compute

When you send a photo to a cloud AI service, you trust that it's processed in a specific data center in a specific country. AWS US-East-1 is a classic example. But how do you verify your compute workload ran in a specific data center? And for

Why Orbital TEEs Are Critical for Secure AI in Space

Introduction To many people on Earth, AI feels like it is taking up all the compute on Earth. Data centers run at high temperatures, causing strain on power grids, and new builds wait in permit queues for years, or are cancelled heavily — a challenge compounded by the vast quantity of
