SPACE ENVIRONMENT AND PROTECTION - 2021/2

Module Overview

Expected prior learning:  Knowledge equivalent to BEng/BSc in physics or engineering, or equivalent learning.




Module purpose:  Engineers and scientists in the space industry need a sound appreciation of the hostile and challenging space environment which includes electromagnetic and particle radiation, space weather, plasmas, ultra-high vacuum and thermal extremes. Through a series of lectures and exercises this module gives students an understanding of the space environment, how it affects engineering systems (especially electronics and materials), all the key effects and how to protect against them. In order to illustrate the wider technical and industrial perspective, guest lectures by specialist practitioners in the field, for example, from the European Space Agency, Airbus, SSTL and OHB are normally provided.

Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate that they have achieved the intended learning outcomes. A written closed-book exam will be undertaken and questions will be set to assess:

·         the student’s overall comprehension of space environment and protection,

·         analytical skills when presented with space environment information or data,

·         problem-solving skills in the field

·         ability to propose and design protection solutions and justify their choice

 

Thus, the summative assessment for this module consists of the following.

·         2 hour closed book written examination.

 

Any deadline given here is indicative. For confirmation of exact dates and times, please check the Departmental assessment calendar issued to you.

 

Formative assessment and feedback

For the module, students will receive formative assessment/feedback in the following ways.

·         During lectures, by question and answer sessions

·         During tutorials/tutorial classes

·         By means of unassessed tutorial problem sheets (with answers/model solutions)

 





 

Module aims

• an overview of the space environment and how it is specified, measured and monitored;
• an understanding of the effects caused on engineering systems;
• an appreciation of the various mitigation methods and tools;
• the ability to apply this knowledge to practical applications.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the following aims.

1. Learning through regular lectures from week 1 to 10. These lectures will include problem solving exercises, enquiry based learning, research-led teaching and in-class discussions.


2. Provision of lectures notes.


3. Provision of case studies and associated discussion.


4. Prepare for summative assessment through intensive in-class revision session.

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.
