ELEC9762 – Space Mission Development
Assignment
The SpaceWorks Mission
This assignment contributes 40% to the total assessment of the course. The assignment report is
due by 11pm on Friday 29 April, 2022 and is to be submitted electronically on Moodle.
Problem Statement: A startup, SpaceWorks, intends to develop and launch a proof of concept for
additive manufacturing in space. The ultimate goal is to develop the technology that will allow the
3-D printing of parts in space. To this end, the company aims to put a small (basic) 3-D printer in
orbit to demonstrate that 3-D printing can be done in space and to study the process. The company
aims to launch a cubesat with a 3-D printer by 1 July 2024.
The satellite is a 12U cubesat and SpaceWorks is in negotiations with Gilmour Space Technologies
to secure a launch to an altitude that provides for a mission lifetime not less than 12 months and
not more than 5 years (it is important that the satellite re-enters to avoid adding to the space
debris). SpaceWorks has also identified a number of Australian Space Agency programs, as well as
small business government programs as a source of funding for the mission.
Deliverables: SpaceWorks needs to develop the mission proposal and plan. This assignment will
produce a report covering phases 0, A, B and C. The deliverables are listed below for each part of
the report. To simplify the project, you may assume that no stabilisation or propulsion are required
and that only subsystems that are directly relevant to achieving the goals of the mission are
considered. For example, you should think about how the success of additive manufacturing in
space may be demonstrated.
Report Structure: The report is to:
− Have a cover page bearing your names and ID numbers.
− Be clearly legible.
− saved as a .pdf file.
− Be submitted online via Moodle.
Report Format: The report is to have a nominal length of 20 pages, with 1.5 line spacing. Guidance
is given for the length of each section. You should not exceed this by more than 20%. A full study
would take tens or even hundreds of pages, so you need to be concise in how you work through the
tasks so as to fit in the prescribed assignment length. It is to contain at a minimum the following
sections:
1. Executive Summary (maximum 0.5 pages, not part of the page count).
2. Introduction: describing the problem, what is required, and what the report contains
(maximum 1 page, not part of the page count).
3. Phases 0 and A: Mission Analysis (5 pages +/- 1 page):
a. Mission statement and mission goals: In this section you are to provide a concise
mission statement and derive the mission goals from it.
b. Mission structure: This comprises the following two major subsections
c. Context: In this section you are to describe the technological, financial, legal and
logistical context of the mission. You should also identify who the actors are and the
mission structure.
d. Mission phases: You should detail the mission phases that apply to this mission and
explain their purpose, the tasks they comprise and the reviews they entail.
e. Mission Concept: You should detail your proposed concept, listing its major aspects
and the required subsystems.
f. Preliminary plan: you should provide a high-level plan, explaining your logic and
briefly mentioning the risks involved.
4. Mission Definition (phases B and C):
a. Phase B: This is the preliminary design phase that culminates in the PDR.
b. Phase C: In this part you should carry out the detailed design phases culminating in
the CDR.
Specifically, your report should address the following points:
Phases 0 and A: Mission Analysis (5 pages +/- 1 page)
1. Elaborate the background to the mission, including relevant assumptions (you are free to
make any reasonable assumptions but these need to be properly justified.)
2. Produce the mission goals/Mission Statement.
3. Identify all the relevant actors.
4. Describe the financial, legal, and logistical hurdles/challenges if any. Remember that both
SpaceWorks and Gilmour Space Technologies are Australian companies and that Australian
laws apply.
5. Develop the Organization Breakdown Structure.
6. Mission Phases - Specify all mission phases and the expected reviews specific to this
mission.
7. Identify mission concepts and assess their feasibility.
8. Produce a system concept.
9. Produce a preliminary, high-level timeline with justification from the project plan.
Phases B and C: Preliminary Definition to Detailed Definition (15 pages +/- 3 pages)
1. Mission Requirements and Specification
a. System level Functional Requirement:
Show derivations of Trade-off Analysis, Functional Flow Block Diagram (FFBD),
Functional Allocation Matrix. Specifically show the requirements after these derivations.
b. Subsystem-level Functional/Performance Requirements: (As explained earlier, you may
make reasonable simplifying assumptions on the technical aspects of what additive
manufacturing in space requires. You should then ensure that you do not include more
than the minimum number of subsystems required for the mission.)
Show derivations of Trade-off Analysis, Functional Flow Block Diagram (FFBD),
Functional Allocation Matrix for the following. Specifically show the requirements after
these derivations.
i. OBC
ii. EPS
iii. Subsystem A
iv. Subsystem B
v. Etc…
2. Project Planning: Work Breakdown Structure. WBS will provide the basis to the derivation of
the schedule of date/time and deliverables, and Gantt chart.
3. Resources
a. Human Resources Planning
b. Financial Budget Planning
4. Design
Outline the following items for one spacecraft design based on the requirements derived
above.
a. Satellite Bus
Description and justification of the choices of each platform subsystem (EPPs, OBC,
etc…) based on performance,
b. Interface Management
Identify interface types, Interface Matrix between each subsystem in the following
aspects:
i. Software
ii. Electrical
iii. Mechanical
c. System Configuration
Description and justification of how the external and internal of the satellite is physically
assembled and integrated needs to be provided. A drawing visualization here will be
beneficial.
5. Design Verification
Verification Matrix, Test Plan, Analysis Plan (List of Simulations).
Marking Scheme: The report will be marked out of 20. The marking scheme will be as follows:
1. Report presentation, English usage, formatting, legibility (20%)
2. Content (80%): This covers the content of the above sections including
a. Understanding of the problem
b. Conciseness and accuracy of mission statement
c. Validity of the assumptions
d. If the context is comprehensively described
e. Correctness of the mission phases
f. Strength and comprehensiveness of the concept
g. Quality of the project plan (Is it comprehensive? Is it justified? Does it involve
unreasonable risk?)
3. Note that deviation from the page count by more than the allowed tolerance would attract
a 5% penalty per page up to a maximum penalty of 20%.
