Kenya Space Sector Formulation—Phase 2

It is in this phase of the road-map that the Kenya space sector organizational framework is defined. This organizational framework should not only present the constituent stakeholders; but, also elucidate the interaction dynamics between the stakeholders. Consequently, we propose the Kenya space sector organizational chart shown in the schematic below. This initial sector organizational framework […]

Space Technology in Brazil

Brazil initiated space activities in 1961 with the creation of the Group for the Organization of the National Committee for Space Activities (GOCNAE) through a presidential decree. This body subordinated to the National Research Council and chiefly operated under the auspices of the Air Force. Following the formation of the Brazilian Committee on Space Activities […]
