MOdular Spacecraft Assembly and Reconfiguration. A Horizon 2020 Funded project, that could change the future of space missions.

What is Mosar?

MOSAR: Modular and Re-Configurable Spacecraft

The Horizon 2020 EU-funded MOSAR project aims to develop a ground demonstrator for on-orbit modular and reconfigurable satellites. The project will investigate and demonstrate technologies that enable a fundamental paradigm shift in satellite design and deployment that could potentially impact all future space missions. The technologies under development include:

  • A set of re-usable spacecraft modules as part of a global eco-system. Each individual module will be dedicated to a specific function as control, power, thermal management, sensors. Once assembled, they will allow the full functionality of the spacecraft
  • A re-positionable symmetrical walking robotic manipulator designed to capture, manipulate and position spacecraft modules, while being able to reposition itself on the spacecraft elements or directly on the modules
  • Standard robotics interfaces, providing mechanical, data, power and thermal transfer for interconnection between the modules, spacecraft and walking manipulator
  • A functional engineering simulation environment and design tool, offering assistance for modules design, system configuration and operation planning, with the support of multi-physics engine

As part of the EU Strategic Research Cluster in Space Robotics, MOSAR will build on and consolidate technological results of previous projects of PERASPERA and its operational grants.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 821966

The project in brief

1 Project. 8 Partners across Europe. 3 Goals:

Reusable satellite modules

Create reusable modules for spacecraft as part of a global ecosystem. Each module dedicated to a specific spacecraft function.


Repositionable Symmetrical walking robotic manipulator. This will capture, manipulate and position the modules.

Robotic Interfaces and Simulation

Standardised robotics interfaces and a fully functional engineering environment to connect and test the modules and walking manipulator.
