Learning unit contents

Spacecraft (satellites or probes) have allowed to achieve considerable progress in many fields of space science including the exploration of the Solar System, geophysics as well as phenomena that occur far away in the distant Universe. This course provides an introduction to various concepts that play a role in modern space missions from the very early stage of the spacecraft design up to the exploitation of the scientific results.
We start with a short overview of the history of space exploration from the Spoutnik satellite to modern spacecraft. We then review some fundamental concepts of celestial mechanics necessary to understand the differents types of orbits used for different missions. The design of a space mission and the scientific exploitation of its results require a deep knowledge of the spacecraft environment and an accurate calibration of the instruments onboard. A major part of this course is therefore devoted to the study of the various external parameters that impact on the design of the mission as well as to the calibration methods (both on-ground and in-orbit). Several examples of past, current and future space missions are presented to illustrate the different steps from their initial conception to the exploitation (and interpretation) of the data collected. The course ends with some discussion about the prospectives of space exploitation.

Learning outcomes of the learning unit

At the end of this course, the students will be familiar with the specific concepts of scientific space missions. They will be able

• to understand the design of the spacecraft and the choice of the best instrumentation depending on the mission's objectives and constraints,
• to analyse the various steps in a space mission, and
• to evaluate its scientific return.

Prerequisite knowledge and skills

Good knowledge of mathematics, physics, and classical mechanics.

Planned learning activities and teaching methods

Several tutorial classes are organised including one where the students simulate the conception of a space mission with a specific scientific objective.

Mode of delivery (face-to-face ; distance-learning)

About 30 hours of lectures followed by several tutorial sessions. The course takes place during the first semester.

Recommended or required readings

The lecture notes are provided as a pdf file in English. The students are invited to make extensive use of the on-line version of this course. This online course contains the lecture notes, copies of the slide show used during the lectures, links to videos that illustrate some aspects developed in the course, some instructions for the personal project as well as a test (not part of the assessment) that helps the students prepare their exam.

Assessment methods and criteria

The assessment includes for 75% the evaluation of an original personal project (written report + oral presentation) on a past, present or future space mission, as well as for 25% the assessment of a MCQ test. The evaluation emphasizes the understanding of the course and the ability to use the techniques that have been taught. To successfully pass the exam students have to learn and understand the course.
