## Summary
Open Robotics has released Space Station OS (SSOS) version 0.9.0, a major integration milestone for the open-source platform designed to simulate and operate crewed space station subsystems. This release transitions the project to a modern development baseline utilizing Ubuntu 24.04 and ROS 2 Jazzy.

Beyond the OS update, the release introduces a new system architecture and improved developer workflows. It features a reproducible environment via Pixi and RoboStack, allowing users to run the stack without a system-wide ROS 2 installation, and provides a new Ubuntu Desktop application path for easier access to the mission-control stack.

## Architectural changes and development workflow
- **Core Subsystems:** The new architecture introduces `ssos_core` for system management and subsystem registration, alongside `ssos_sim` for simulation control, world state management, and fault injection.
- **Standardized Interfaces:** The platform now implements shared ROS 2 interfaces for subsystem lifecycle management, heartbeat monitoring, telemetry, and fault handling.
- **Environment Reproducibility:** Integration of Pixi and RoboStack enables a locked development and runtime environment, which was validated through 144 automated tests with zero failures.
- **Deployment Options:** Users can now utilize a Tier-1 Ubuntu Desktop application for launching the mission-control stack via desktop shortcuts, bypassing manual ROS launch commands.
- **Reference Implementation:** The Environmental Control and Life Support System (ECLSS) serves as the primary reference implementation for the new architectural framework.

## Why it matters
This release lowers the barrier to entry for robotics engineers by providing a containerized-style reproducible environment that avoids system-wide dependency conflicts. It also establishes a scalable framework for integrating complex, multi-subsystem hardware simulations within the ROS 2 ecosystem.
