Kenya Space Sector Formulation—Phase 5 & 6

The on-orbit validation of domestically developed space technology accomplished in Phase 4 will need to be followed by entrenchment of this achieved proficiency in a domestic cutting-edge space technology manufacturing base. In doing so, Kenya will start to climb one level on the space technology capability hierarchy pyramid to become a Spacecraft Manufacturer. This significant […]

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 […]

Space Missions—II

Space Missions Classification Space missions can be categorized based on a number of factors such as mission duration, spacecraft size, orbital location, cost, objective, geographic origin etc. The classification approach is usually motivated by the intended use of the classification exercise’s outcome. However, a prudent and insightful categorization of space missions focuses on the nature […]
