Development of comprehensive analytical
models that describe motion in the vicinity of small
irregularly shaped bodies is faced with numerous inimitable
challenges.
Here are some videos I participated in a while back as part of the Arizona State University’s Interplanetary Initiative.

Read more "Book Chapter-Analysis and Control of Nonlinear Attitude Motion of Gravity-Gradient Stabilized Spacecraft via Lyapunov-Floquet Transformation and Normal Forms"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 […]

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-satellites

This progression will be realized through further expansion of the resources and capacities formerly initiated in the preceding phases. Expanding capabilities will further be augmented by the introduction of completely new competences. […]
Read more "Kenya Space Sector Formulation—Phase 4"I am delighted that after a brief hiatus, the regular posts and discussions on establishing a space space in Kenya have now resumed. Let us keep the conversation going. The next post will be on Kenya Space Sector Formulation Phase 4.
Read more "Discussion Resumes!"It is in this phase that the physical establishment of the proposed space sector’s infrastructure and tangible capacity commences. A concurrent tripartite approach targeting i) human, ii) organizational and, iii) societal capacity development is required to ensure a comprehensive and efficacious inception of the Kenyan space sector. Similarly, identification and strategic engagement of potential collaboration […]
