SpaceComputer

By 2030, a quantum computer could read the encrypted data being stolen today. Harvest Now, Decrypt Later: hackers store encrypted data now and wait for quantum machines to catch up. They steal data that will still have value in being encrypted in 10 years. The top five sectors with valuable data: 1. Pharma R&D and Patented IPs 2. Identity and biometric records 3. Defense: classified files 4. Healthcare medical records 5. Space comms and satellite telemetry At SpaceComputer we focus on the space component. Where NIST has standardized the algorithms, we can begin the migration for satellites to a secure post-quantum future. The countdown is already on for space.

@grit10x Thanks again for a great video Grit! And yes - literal space fabric, love that!🤣

my 'space fabric' is here 💛 we are about to witness the launch of a novel secured orbital compute hardware & software architecture for small satellites 🛰️ a new level of trust and security for builders. LFG @SpaceComputerIO

The SpaceX IPO will usher in the next phase and expansion of space tech, creating a root of trust beyond contracts for an emergent, modular, and interoperable space economy. At SpaceComputer, we're building the trust layer for space.

As launch and connectivity in orbit mature, the frontier moves compute, data, and the systems that make them secure and verifiable. The next layers will be built by new space startups, rather than restricted to governments and legacy organizations.

What does the SpaceX IPO mean for new space infrastructure? 🧵

Head to our docs page docs.spacecomputer.io/docs/how-to/kms Explore our KMS service spacecomputer.io/solutions

Your KMS is only as strong as the cryptographic algorithms protecting it. Most KMS infrastructure relies on ECC and RSA, both vulnerable to Shor's algorithm on a quantum computer. NIST has standardized the PQC replacements: ML-KEM, ML-DSA, SLH-DSA. For satellites, the timeline is compressed. Hardware in orbit cannot be re-keyed. We designed SpaceComputer KMS to be algorithm-agnostic from day one. Learn how PQC and KMS fit together ↓

Great to see sci-fi becoming reality. Congratulations to the SpaceX team on a monumental IPO 🚀 We’ve always been proud to have SpaceX as the launch provider for @SpaceComputerIO’s satellites. From reusable rockets to Starlink and beyond, SpaceX’s work is helping make the expansion of space possible. Excited for what comes next for SpaceX and the space industry. To infinity and beyond!

We are believers in the multiplanetary, and building beyond what we think is possible. It's part of why SpaceX has been a great launch provider for @SpaceComputerIO's satellites, and are excited for more advancements from SpaceX for the space industry and for humanity! Congratulations on the IPO, SpaceX team! 🚀

From January to August in 2025, ~117 cyber incidents targeting space systems were reported, up 118% from the same period in 2024. And one of the attack surfaces that are easiest to access from Earth? Ground stations. Ground station security is one of the first layers of space infrastructure that needs cybersecurity measures in place, as they are the direct connection point to satellites in orbit. We created a comprehensive breakdown of ground station cybersecurity, and strategies for threat mitigation. Link below👇

The space economy is in launch mode 👽🚀 With the SpaceX IPO monumental event, the capital flowing into space has never been higher! The global market will reach $700 billion in 2026. The industry is seeing an influx of everything from launch providers, ground station buildouts, analytics and AI enablement across Earth and literally to moon and beyond! Space is highly interconnected, and we’ll only see deeper layers of the space sector unfold in the coming year already. I’ve compiled and made a market map of the space companies and players you should be aware of. The future is in space. This is the first part of a 3-part series Stay tuned, next up is LEO to GEO 🛰️

You can prove your satellite is in orbit. Why it matters: - earth observation 🌍 - sensing 🔎 - key management 🔑 - AI inference 🤖 All of it depends on trusting where your compute runs. It’s a multi-billion dollar market, and we’re bringing it into the post-quantum age

The full protocol and threat model are in the Space Fabric paper. Start with Section 5.3 for the protocol, and Section 6.3 for the security proofs behind the quorum threshold. spacecomputer.io/spacefabric

In low Earth orbit, collecting endorsements takes 4–7 passes (roughly 6–11 hours). It runs once, certifying the satellite for its entire multi-year life. After that, the satellite just presents its certificate. Re-verification takes milliseconds, with no need to re-run the protocol.

It takes less than 11 hours to prove a satellite is genuinely in orbit. You do it once, with multiple ground stations on Earth, and it holds for the satellite's entire life. 🧵
