Prerequisites:

Students are expected to be familiar with Rational Mechanics and Mathematical Analysis, including the elementary theory of Ordinary Differential Equations.
A fair amount of curiosity about dynamical phenomena observed in the Solar and other planetary systems is useful, together with an interest in their precise modeling and computation and the design of exploration missions. 
Target skills and knowledge:

1) Develop an understanding of dynamical phenomena in gravitating systems.
2) Application of Newtonian Mechanics to the solution of the fundamental problems of the Celestial Mechanics of natural bodies and artificial satellites.
3) Solution of Inverse Problems with applications to Orbit Determination.
4) Introduction to the design of orbits for planetary and interplanetary exploration.
5) Develop numerical computations in Matlab (or compiled languages), including the numerical integration of the equations of motion.
6) Learn how to use the General Mission Analysis Tool (GMAT). 
Examination methods:

Evaluation of the homework and final project report. Oral presentation of final report and discussion of the results and other topics covered during the lectures. 
Assessment criteria:

The knowledge of the topics discussed during the lectures, the use of the correct terminology, and the ability to connect different topics will be evaluated with:
1) Homework assignments (40% of the final mark).
2) Final project and presentation (30% of the final mark).
3) Final oral exam at the moment of the final project presentation (30% of the final mark). 
Course unit contents:

1) The equations of motion of gravitating systems.
2) The TwoBody Problem and an initial value problem (IVP).
3) The TwoBody Problem and a boundary value problem (BVP).
4) Orbital maneuvers.
5) Space and time reference systems.
6) The computation of a Keplerian ephemeris.
7) Preliminary orbit determination.
8) Keplerian relative motion and its generalization.
9) Regularization and Universal Formulation of the TwoBody Problem.
10) The TBP as a boundary value problem (BVP) – Lambert targeting.
11) The Problem of Three Bodies and its homographic solutions.
12) The Circular Restricted ThreeBody Problem – Jacobi’s integral, surfaces of zero velocity, Lagrangian points, Stability, Periodic orbits.
13) The theory of Patched Conics and the design of gravityassist interplanetary trajectories.
14) Elements of perturbations and a the motion of an artificial Earth satellite. 
Planned learning activities and teaching methods:

Lectures, homework assignments, Matlab (Fortran, C++) code development, computer lab activities, special topic analysis during final project. Lectures are given in English. 
Additional notes about suggested reading:

Lecture notes of the teacher "S. Casotto, Lezioni di Meccanica Celeste". The list of suggested textbooks is given.
