The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.
Find out more about space activities in our 23 Member States, and understand how ESA works together with their national agencies, institutions and organisations.

The International Berthing Docking Mechanism (IBDM) is an androgynous, contact force-sensing, low-impact docking system, capable of docking and berthing large and small vehicles.
The IBDM consists of the Soft-Docking System and the Hard-Docking System. The first captures and actively dissipates the kinetic energy of the two spacecraft. The second makes the structural pressurised connection between the spacecraft.
The IBDM is fully compatible with the International Docking System Standard (IDSS) defined by the Station partner agencies and with the new docking ports being made available at the Station.
ESA developed the docking system in cooperation with NASA, with the goal of building a modern docking system for space vehicles visiting the Station after the Space Shuttle’s retirement.
The dual active control loop markedly improves on existing technology by reducing the docking forces on the space infrastructure and by enabling the capture and docking of a wide range of spacecraft mass and flight envelopes.
QinetiQ Space has been leading IBDM development since the beginning and it has set up an industrial team including SENER (Spain and Poland), responsible for the Hard-Docking System, Ruag AG (Switzerland) for the linear actuators, and Maxon (Switzerland) for the electric motors.
