Open MCT is a web-based mission control framework for visualizing telemetry data on desktop and mobile devices.

The framework addresses the need to build applications for planning, operation, and analysis of systems that produce telemetry data. It provides a generalizable foundation that abstracts away common mission control concerns, allowing developers to focus on domain-specific functionality. The tool is built as a plugin-based system using JavaScript, npm, and webpack, enabling extensibility through custom plugins rather than requiring modifications to core code.

Open MCT suits teams building monitoring and control systems for spacecraft, rovers, or other telemetry-producing systems. It is particularly valuable for organizations that need rapid development of mission control interfaces without building visualization infrastructure from scratch. The framework works on both desktop and mobile browsers, making it applicable to scenarios where operators need access from multiple device types. Anyone considering adoption should know that the project is actively used by NASA for real spacecraft missions and rover operations, which indicates production-grade maturity for high-stakes applications.

The project maintains active development with regular commits across the codebase. Testing infrastructure is comprehensive, including visual regression testing and code coverage tracking. The maintainers actively solicit user feedback through multiple channels including GitHub issues, discussions, and direct email, and they encourage community contributions by showcasing implementations in a dedicated section. Documentation is substantial, with tutorials and getting-started guides provided to lower the barrier to building applications with the framework.
