The LibreCube Initiative is a non-profit organization that provides the framework to organize and manage the activities that are needed in order to achieve the objectives outlined below.

The LibreCube Community is an open community of people from all around the world that are united in the spirit of sharing knowledge and working together for exploring space and earth. It is open to anyone to join.

The name LibreCube is inspired by two things: Libre stands for our approach of sharing and collaborating freely and openly; Cube comes from the idea of using small, modularized building blocks for our systems, based on the concept of CubeSats.


To allow everyone to take part in peaceful space and earth exploration for the good of mankind.

Mission Statement

  • Form a community of people from all around the world with interest in conducting space and earth exploration missions and provide means for them to actively engage in the utilization and development of LibreCube’s open source projects.
  • Forster the standardization of LibreCube’s mission elements to ensure compatibility and facilitate collaboration.
  • Establish a generic reference architecture for typical LibreCube mission scenarios that can then be tailored and adapted to specific mission needs.
  • Promote the use of free and open tools for developing and implementing such missions.

How it Works

LibreCube’s goal is to provide the needed elements for your space or earth exploration mission in the form of open source projects. You pick the elements you need, add your own specific elements, such as sensors and scientific instruments, and build and run your mission from that. Although LibreCube’s primary focus is on enabling affordable space missions in the lower earth orbit (see definition of LEO) it is not limited to that: all LibreCube elements can equally well be used for terrestrial exploration.

The LibreCube mission architecture elements are based on two defining concepts: The CubeSat design concept (seeĀ here), which provides for a standardized interface with the launch rocket and hence making the launch of such satellites affordable and frequent; and the concept of using a stack of modular avionics and payload subsystems and equipment boards (defined by the LibreCube Board Specification) that allow for high re-usability between missions and easy replacement.
