Before we answer this question as applicable specifically in the Kenyan context, it is essential to understand what I mean by Space-based Technology which is used interchangeably with Space Technology. Space-based Technology refers to any technical capability that incorporates a man-made extra-terrestrial segment in its intended operation here on earth. Therefore, palpable examples of space-based […]Read more "Why Kenya Needs Space-Based Technology"

In this new article, we present a straightforward approach to accomplish model order reduction on the invariant center manifold for large-dimensional nonlinear systems subjected to external periodic excitations. This relatively plain and direct approach is applicable to both parametrically excited and constant coefficient nonlinear systems. Our approach is powerful because it is liberated from typical […]Read more "Center Manifold Reduction of Nonlinear Dynamics With External Periodic Excitations"
In my latest article, we present a powerful direct approach to simplify complexly structured nonlinear systems with external periodic excitation via normal forms. This approach is liberated from special treatment of nonlinear systems such as ‘book-keeping’ parameters, detuning parameters etc. It does not mandate the system to be minimally excited and the system may possess […]Read more "Simplifying Nonlinear Systems With External Periodic Excitation"
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 ASU-led NASA Psyche Mission is offering a free self-paced online course that outlines the process of NASA space mission development from idea to flight. The series of free online courses are called the NASA Psyche Mission Innovation Toolkit. The course provides a valuable insight into space mission development campaign. I highly recommend this course […]Read more "Free Online Course on Space Exploration!"

This is a research article I co-authored as part of the Harvard University Kennedy School of Government Research Working Paper Series . It focuses on the theme of Space Technology for Sustainable Development and the unique role played by small satellites. https://www.hks.harvard.edu/publications/space-technology-and-africas-development-strategic-role-small-satellitesRead more "Space Technology and Africa’s Development: The Strategic Role of Small Satellites."
I am happy to share a link to my latest journal article scrutinizing the systems engineering methodologies and approaches of formulating and implementing space missions. A survey of space mission architecture and system actualisation methodologies This research seeks to improve space mission actualization methodologies by examining non-traditional emerging trends in space systems engineering practices. Further, we […]Read more "Space Systems Actualization"
Despite this early opportunity coming to Kenya’s doorstep, the country remained oddly aloof to adopt space technology as part of the national development agenda.Read more "Absurd Anecdote: History of Space Technology In Kenya"
