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 d
etailed 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%.
