The importance of space flight and satellite activities in the modern economy is significantly increasing, they are not used exclusively by government as it was in the past, but by privates too. The space economy is growing larger and as a consequence the space activities are becoming more affordable. The growing complexity and ambition of the space projects is driving the space industry to detach from the traditional method of launching a fully integrated system on a single launch vehicle. In the future, the majority of the systems could be built and repaired in space. On-orbit Servicing, Assembly and Manifacturing (OSAM) offers a solution that can remarkably increase the performance, resilience and lifetime of space systems compared to the traditional method.
