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

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.

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.

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

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!

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

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

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. 🧵

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

Our satellites will have an unspoofable “caller ID.” All it takes is a protocol that runs once, and can be verified for the course of its lifetime. We use a network of ground stations to run a challenge–response handshake as the satellite does its first passes in orbit. When
