We are thrilled to announce that SpaceOS, the world's first purpose-built, secure-by-design operating system specifically engineered for the next generation of shared payloads and software-defined satellites, is scheduled for launch aboard SpaceX's Transporter-13 mission.

SpaceOS represents a fundamental shift in how we approach satellite computing, bringing the power of formally verified unikernels to space applications.

Security: Built-In, Not Bolted-On

SpaceOS blocks over 70% of zero-day vulnerabilities through:

  • Memory-safe OCaml programming eliminating entire classes of security issues
  • Formally verified components providing mathematical proof of correctness
  • Compact unikernel design that dramatically reduces attack surface without computational overhead

By design, SpaceOS prevents the security vulnerabilities that plague traditional operating systems, making it ideal for the hostile space environment.

Efficiency: Doing More with Less

Testing with EU industry partners demonstrated remarkable results:

  • SpaceOS operates 20 times smaller than conventional container solutions
  • Full functionality preserved for payload isolation
  • Minimal resource footprint maximizes available computing capacity
  • Optimal use of limited satellite power and memory resources

This efficiency means satellite operators can run more applications on the same hardware, directly increasing the value of their orbital assets.

Manageability: Simple Operations for Complex Systems

The platform provides integrated tools for:

  • Payload Deployment - streamlined application installation and configuration
  • Remote Updates - seamless software updates without service interruption
  • Resource Allocation - dynamic distribution of computing resources across applications
  • Operational Visibility - real-time monitoring and management of shared orbital resources

Free In-Orbit Validation

In partnership with DphiSpace, we're offering free in-orbit software validation for developers and satellite operators. Test your applications in the real space environment with optional data transfer services available.

This is a historic moment - the convergence of formal verification, unikernel technology, and space computing. SpaceOS makes satellites more secure, more efficient, and more valuable.

Stay tuned for launch updates and in-orbit performance reports.
