SPACE SCIENCE AND TECHNOLOGY
We aim to present to the student an introduction to space science, focused on Solar System structure and evolution, and to space technologies used in space activities, in particular system engineering of a spacecraft.
Knowledge and understanding: The student must demonstrate knowledge and understanding of the fundamentals of Solar System science (physics, geophysics, geology) and the physical laws and technologies on which a space project is based upon.
Ability to apply knowledge and understanding: Students must demonstrate to use their own acquired knowledge to discuss and explain the main physical processes acting in the Solar System, limits and capabilities of space technology.
Independent judgment: The student must be able to evaluate from his/her point of view physical problems different from what was discussed during the lessons.
Communication Skills: The student shall be able to support a conversation on the topics covered during the unit, with proper scientific language and by correctly using mathematics and plots.
Learning Skills: The student must be able to update and deepen autonomously specific topics and applications related to studied topics.
The student must know mathematical analysis and classical physics, including kinematics, point and rigid body dynamics electro-magnetism.

Slides used during the lessons are also to be considered (they are made available upon request).
The purpose of the assessment is to quantify the level of achievement of the training objectives previously indicated. The verification procedure consists of an oral examination during which the ability of the student to apply the topics discussed during the course to different problems is tested.
