Artificial satellites as a research area encompasses the scientific and engineering study of human-made objects intentionally placed into Earth or other celestial orbits for observation, communication, navigation, and experimentation. Research focuses on orbital dynamics and mission design, attitude determination and control, space environment interactions (radiation, plasma, micrometeoroids), and advanced materials and power systems for long-duration operation. It also includes development of miniaturized platforms (e.g., CubeSats), payload instrumentation for remote sensing and scientific measurements, formation flying and constellations, on-orbit servicing, autonomy and fault management, and the impacts of satellite proliferation on space traffic management and orbital debris mitigation.
Not much can surprise someone who partook in four shuttle missions and three space walks during a 36-year career with NASA. Let alone, for someone who has spent their life studying space and space travel, the proposal of ...
