en.Wedoany.com Reported - Singapore-based startup SpaceComputer is preparing to conduct in-orbit testing of its hardware and software later this year. The company's first product, named Space Fabric, is a hardware and software architecture that connects ground stations with satellites through secure, physically isolated computing units, and enables the sharing of computing resources between satellites.
The core concept of Space Fabric lies in building an open, interoperable "Space Internet." SpaceComputer co-founder and blockchain entrepreneur Daniel Bar stated that despite growing investment in orbital infrastructure, there hasn't been much thought given to a "Space Internet." He believes an open, protocol-oriented approach is needed, allowing different stakeholders to interface with each other, rather than operating in siloed "islands." To this end, Space Fabric's printed circuit boards will generate encryption keys in orbit to protect data. Bar stated, "There is no need to trust us or the operator running Space Fabric." The circuit board also integrates two mutually authenticating redundant security elements to enhance system resilience and security.
To ensure the smooth execution of this test, SpaceComputer is integrating Space Fabric with the printed circuit board, preparing it for launch aboard an undisclosed satellite. The launch is planned for October 2026, with the goal of verifying in a real space environment whether the circuit board can stably generate keys and whether the mutual authentication mechanism of the dual security elements is reliable, thereby testing the entire architecture's tolerance to radiation and extreme temperatures. Beyond Space Fabric, the company is also developing a product called Orbitport, an Application Programming Interface (API) designed to act as a secure gateway between satellites, payloads, and ground-based computing. Co-founder Filip Rezabek, a PhD student at the Technical University of Munich focusing on cybersecurity, stated that Orbitport will make interaction with ground station providers a "more seamless experience."
SpaceComputer was founded in 2024, co-founded by Daniel Bar and Filip Rezabek. Since its inception, the company has raised $10 million through pre-seed and seed funding rounds, with investors including Maven11 and Lattice. Its advisory team includes Dahlia Malke, a computer science professor at the University of California, Santa Barbara, and Will Heltsley, former Vice President of Propulsion at SpaceX. This upcoming in-orbit test marks a critical step for the company in bringing its secure computing infrastructure to the space environment, with application prospects spanning multiple fields, from secure computing and communications to geospatial data provenance verification.
