This module builds on the introduction to space engineering given in levels 4 and 5 to give a detailed understanding of space vehicle design, broken into core (eg. power) and mission enhancing (e.g. propulsion) subsystems. This is not intended to enable you to carry out detailed design of effective space missions, which requires a graduate level course, but will provide (a) a thorough understanding of the challenges of space engineering, (b) a toolset, reference material and confidence to tackle future design problems you may face, and (c) an understanding of the drivers for space engineering (politics, economics and technology in that order). Context will be provided through reference to a number of past UK, European and International space missions.
The module aims to allow you to understand design challenges and specify requirements for
The module is designed to be delivered as blended learning, to support L6 students on site as well as those who are on placements. The module is primarily delivered through recorded lectures, computing and software exercises and some practical classes (not available to students on placement). A booklet of worked example problems designed to support the exam assessment will be made available, and for those students on site will be worked through in fortnightly tutorial sessions with a graduate teaching assistant. Periodic guest lectures and workshops using industry experts will take place, material from these if not commercially sensitive will be made available for download. Industrial visits to spacecraft subsystem manufacturers will be offered. Additional support materials including excerpts from core texts will be available through Canvas.
On successful completion of the module, students will be able to:
These learning outcomes have been designed to be accomplished by students who are on site and also by students on placement with space companies.
1. Space systems engineering
2. Spacecraft electric systems. Includes
3. Spacecraft mechanical systems
4. Space transportation
5. Space mission design. Includes
The learning outcomes will be achieved through a combination of formal lectures, tutorials, seminars, computing laboratory exercises, electronic learning tools and independent study.

Average of 4 formally taught hours per week (approx 96 hours). Lectures will be recorded eg. using Camtasia and made available online. |
Problem solving based tutorials | Prepared by academic staff and supported by graduate teaching assistant. | 1 hour every other week (10 hrs total). Problem booklet and solution set available online. Students on placement can submit answers via email for formative feedback. |
Guest lectures providing industrial context | Delivered by experts from UK based space engineering companies and academia. | At least 2 during each teaching block. Material to be made available on line if permitted. |
Skill development activities |
Three activities, from at least 2 of the following areas are to be carried out: 1. System modelling using spreadsheet tool 2. Commercial software usage 3. Experimental design In addition each student will need to prepare regular presentations on their individual project for feedback from the class / teaching team. |
To develop space system design skills, experimental measurements, predictions using spreadsheet tools, high quality report writing and confidence in presentations. To be prepared during guided independent study time. Option (3) may not be available to students on placement. Presentations via webex / Skype. |
Independent study driven by assignments |
Covering system engineering for spacecraft with emphasis on: 1. Core spacecraft subsystem design principles - mechanical and electrical 2. Space mission design including trajectory analysis, applications, instrument design and selection, platform selection and launcher selection. |
A written assignment requiring design work, analytical problem, solving, numerical simulation and concise written summaries. To be peer reviewed in pairs to build teamworking and small group analysis skills. Students on placement will submit draft work by email for review. |
In-class tests | There will be two formative tests |
2 tests in Nov and March. To be provided through online platform for placement students. |

1. End-of-module examination worth 50% of the assessment. To be sat by al students at the same time whether on campus or on placement.
2. A written assignment demonstrating the student's ability to carry out basic design calculations and systems engineering for space vehicle electrical and mechanical systems, and to summarise the additional elements required for a mission including instruments, trajectories and launchers. This will require a written report, submission of a system model (spreadsheet) and a short presentation (via Skype / Webex for placement students). Worth 20% of the overall assessment.
3. A portfolio comprising two short reports on skill development activities (not exceeding 4 pages) each worth 15%. Feedback from the first report will enable students to develop their report writing skills before the second report.
Formative assessment will be provided in the form of regular and concise feedback on set tasks and tutorials, plus interaction with industry experts and visiting lecturers throughout the academic year.
Learning Outcome | Assessment Strategy |
---|---|
1) Carry out basic design (specification and sizing) of core spacecraft subsystems using standard software such as Excel in MS Office | End of year examination, portfolio and coursework plus formative assessment (tutorials) |
2) Understand the importance of systems engineering, requirement analysis, instrument and payload selection and orbit mechanics on preliminary mission design. | End of year examination, written assignment and formative assessment |
3) Specify and size spacecraft mechanical and electrical subsystems with additional detail on structures and propulsion, launchers and re-entry systems. | Written assignment |
4) Explain the difference between space vehicle and space mission design, using topics such as remote sensing, science /exploration & small low cost space missions. | Written assignment, end of year examination. |
5) Understand the fundamentals of space transportation (propulsion, launchers, re-entry systems) | Examination and written assignment. |
6) Demonstrate a range of space vehicle related design skills for example mechanical / measurement, materials selection, concept design and system modelling. | Portfolio (Lab write up) |
