MOdular Spacecraft Assembly and Reconfiguration, changing the future of space missions.

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

What is Mosar?

MOSAR: Modular and Re-Configurable Spacecraft

The Horizon 2020 EU-funded MOSAR will aim at developing a ground demonstrator for on-orbit modular and reconfigurable satellites. The project targets to integrate and demonstrate technologies required to enable a fundamental shift of paradigm in designing and deploying satellites in future space missions. That will 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 repositionable symmetric walking robotic manipulator allowing to capture, manipulate and position spacecraft modules, while being able to reposition itself on the spacecraft elements or directly on the modules
  • Standards 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.
