<!-- layout: default title: What is SSOS? nav_order: 2 --> # What is SSOS? ** [Concepts](https://en.spacedata.jp/news/202411_ssos)** ** [Features](features.md)** ** [Roadmap](roadmap.md)** Space Station OS (SSOS) is an open-source development platform for space stations, built on ROS 2 to support interoperability, modularity, and scalability across various space station projects. By unifying core functions like thermal control, power, and life support into reusable modules, Space Station OS provides a universal environment that allows engineers globally to develop and operate space stations collaboratively. This enables rapid innovation and cross-mission compatibility, lowering development costs and enhancing sustainable space station operations. Space Station OS represents a global effort to democratize space station technology, welcoming contributions from the international aerospace and robotics communities.
