In my latest journal article I have a mouthwatering treat in; gravity gradient attitude stabilization, periodic nonlinear spacecraft attitude dynamics, Chebyshev polynomials, Hopf bifurcation, sliding mode control, Lyapunov-Floquet transformation, Normal Forms, system state augmentation etc. The article titled ” Control of Nonlinear Spacecraft Attitude Motion via State Augmentation, Lyapunov-Floquet Transformation and Normal Forms ” is […]Read more "Control of nonlinear spacecraft attitude dynamics"
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 […]Read more "Kenya Space Sector Formulation—Phase 5 & 6"
African moon mission seeks cash for first phase By Paula Park A group of African space enthusiasts have taken to the internet to raise money for what they say will be the continent’s first moon mission. Africa2Moon’s main goal is to send a probe to orbit or land on the moon and beam back video […]Read more "African Space Technology Initiatives"
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 […]Read more "Kenya Space Sector Formulation—Phase 2"

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 […]Read more "Space Technology in Brazil"
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 […]Read more "Space Missions—II"
