SPACE DYNAMICS AND MISSIONS - 2021/2
Module code: EEE3039
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
Expected prior learning: It is helpful, but not essential, to have studied module EEE2043 – Space Engineering and Mission Design (5-spe), or to have equivalent learning.
Module purpose: This module gives a hands on approach to mission analysis and develops mathematical descriptions of the natural orbital and rotational motions of spacecraft. Material is delivered through a series of lectures, group problem solving and assessed assignments. The application to mission design is explored through group work and assessed labs.

Not applicable: students failing a unit of assessment resit the assessment in its original format.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of terminology and theory of orbital motion and spacecraft pointing. It will assess the ability to analyse problems by applying mathematical models to solve and predict disturbance effects and mitigation. The Assignments will assess the ability to design space missions applying the theory to practical problems. The first assignment will evaluate the students ability to program some of the concepts while the second assignment will then assess their ability to put together a practical mission solution.
Thus, the summative assessment for this module consists of the following.
· 2 hour closed book written examination
· Software assignment An assignment involving the programming of and expl0oration of simple mission concepts. (5-10 pages) due Monday Week 6 (assignment deadline should be checked in the Assignment Calendar)
· Mission Planning Assignment A software assignment that builds on the skills of the previous assignment but looks in more depth at a particular mission (circa 10 pages) due Monday Week 12 (assignment deadline should be checked in the Assignment Calendar)
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
· During lectures, by question and answer sessions
· One to one discussions with lecturer during problem solving
· Peer feedback during group problem solving
· Through guided learning on SurreyLearn through provided material and problem solutions
· During supervised software laboratory sessions
· Via marking of written reports on assignments
- To introduce the student to develop a solid understanding of the classical dynamics of spacecraft and apply this knowledge in mission design for achieving pre-specified objectives and adequate pointing. This is to be achieved through a series of lectures, regular group problem solving with direct interaction with the lecturer and two lab based software assignments.

Independent Study Hours: 110
Lecture Hours: 30
Laboratory Hours: 7
Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the following aims.
The teaching strategy is through a taught theoretical foundation, interposed with direct group problem solving and with application of theory to real missions. A more significant mission design is worked on through software labs, where some aspects are looked at in greater depth. In all aspects there is direct interaction between lecturers and the groups to provide feedback on their understanding, and to push their understanding to solve new problems based on their knowledge.
Learning and teaching methods include the following.
Teaching and learning is by lectures, group problem solving and assessed software assignments. 2 hours lectures plus 1 hour problem solving classes per week for 10 weeks. 1 hour assignment lab per week for 10 weeks.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
