- 3. Mission Concept Mission Goal: Direct an impactor into Deimos at high velocities to launch a plume of surface and subsurface debris into space. The plume will be analyzed by an infrared spectrometer to determine the composition Deimos. This will determine whether Deimos is a C or D type asteroid, or Mars ejecta. In addition, prebiotic volatile concentrations will be analyzed to determine asteroid contributions to early life. Mission Objectives: - The impactor shall collide with Deimos’ surface and generate a plume sufficient enough in size for the CubeSat Spectrometer to detect - The impactor shall penetrate Deimos’ surface deep enough to expose volatile compounds including oxygen, carbon dioxide, carbon monoxide, water, and ammonia - The CubeSat shall analyze the plume with a spectrometer and determine the 1.3 µm absorption levels, as well as the absorption levels of volatiles 3
- 4. Key Requirements The two major design goals of the spacecraft are to generate a plume of Deimos subsurface material, and to relay the composition of the material to Earth. The driving requirements serve to fulfill these two goals either directly or secondarily. 1. Shall be ready for launch by July 20th 2020 2. Shall arrive at Deimos between February 19th 2021 and February 20th 2021 3. Shall not exceed 5.6 million dollars in total cost 4. Shall have an acceptable amount of risk. 4

- 17. Project Risk Areas and Mitigations 17 Risk Assessment Likelihood Consequence 1. Propulsion isn’t ready in time of launch ○ If so, we will have to find a new propulsion system. 2. Production schedule surpasses time allotted until launch ○ We have margins built into our production schedule to account for more. 3. Components don’t meet testing standards ○ The schedule margin accounts for fixing 4. Costs are higher than expected ○ Total mission cost with contingency is still the total allocated budget 1 2 6 4 3 5
- 18. Descopes Reduce the amount of quality testing Reduces build time but increases risks Reduce the amount of employees Reduces salary costs but increases build time Reduce the amount of trips to conferences and design review trips Reduces costs but reduces centainity of design. 18
