Abstract: Nowadays, despite the technological development experienced by science and technology as can be seen through the available powerful computer machines, the analytical and semi-analytical methods to study different space problems are still of great importance in the fields of celestial mechanics and astrodynamics. From the physical understanding of the motion of celestial bodies to the planning and designing of space missions, the use of mathematical models and techniques to deal with a very large number of contemporary problems plays a fundamental role in the progress of human knowledge and society. In this context, this presentation will cover the use of different mathematical techniques to deal with a diversity of current problems in celestial mechanics and astrodynamics. Topics such as the investigation and design of disturbed orbits used for the exploration of minor bodies, the modeling of the complex roto-orbital dynamics of celestial bodies and the mitigation risk of space debris will be discussed in order to highlight the relevance that analytical and semi-analytical techniques still present in the fields of space science.
Short-Bio: Josué Cardoso dos Santos has recently joined the University of Colorado at Colorado Springs (UCCS) as assistant professor after spending a period as visiting researcher at the University of California San Diego (UCSD) and completing a JSPS postdoctoral fellowship program at the Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency (ISAS/JAXA). He holds PhD a master’s degrees in Physics (concentration areas: Celestial Mechanics / Astrodynamics / Dynamical Astronomy) from São Paulo State University (UNESP) at Guaratinguetá, where he also obtained a degree in Mathematics (with honors). During his PhD he was a visiting researcher at the University of Colorado Boulder (USA) and at ISAS/JAXA. He was also a postdoctoral researcher/research associate at the Technion (Israel), ITA and INPE (Brazil). He has experience working with the teams of the Japanese space missions DESTINY+ (to visit the asteroid 3200 Phaeton) and MMX (to visit the Martian moons and bring samples from Phobos back to the Earth), being also a member of the MMX’s Geodesy Science Strategy Team (GSST). Areas of interest: Celestial Mechanics, Astrodynamics, Space Exploration, Space Missions, Dynamical Astronomy and History of Science.
