Space is led by the industrial partner AL in cooperation with VTT. Spacecraft is typically designed, developed and integrated by large international consortia of multiple stakeholders. As a result, high-technology sub-system or payload designed in one country is manufactured through integration of components coming from several other countries and finally integrated at system level in a third place. With the envisaged platform developed in WEKIT, time-demanding as well as generating only cost voices elements shall be drastically reduced. Tasks to be tested include: Performance of sub-system test bench; Integration and performance of payload/subsystem at system level, and Ground-ground training for astronauts.
