Great proposal with special attention to answering all of the challenge questions with appropriate metrics. Concept has accommodates operational variability and considers environmental factors in analysis.
This is a strong and detailed submission that is credible, highly creative, and represents a biologically inspired solution. Estimates of thermal and power considerations could be better defined. Proposer may also want to consider operation of the "pill bug" system in a dusty environment and mitigation strategies for dust contamination and transfer of dust between the logistics carrier and other assets. Great consideration of scalability (larger diameter options, spiral configurations) and presentation of overall concept of operations and interaction with other surface assets. The design was of a very high fidelity and proposer provided details on mechanisms and interfaces. Creative reuse ideas for base units are also included. There could be more information on communication strategies/data logging.
Technically credible proposal judged as feasible for implementation -- supporting analyses are provided for structural, power, and thermal considerations. Proposer could consider some additional aspects of operations in the lunar environment (e.g., dust mitigation, durability, maintenance and repair). Very good, high quality design work. Lacks some detail in packing, offloading, and handling. Good creative reuse ideas for cargo container post-initial use. Primary drawback of current design is that it is limited in scalability.
Concept appears to be feasible and captures some metrics for appropriate assessment. Specific information regarding power and thermal specifics was not present, but strong information regarding structural characteristics was present including environmental considerations. Consideration of interfaces with other containers to allow stacking was also present offering options for storage solutions for launch. Consider teaming in future competitions with power/thermal experts to produce stronger submissions.
This is a good proposal and concept. The graphics are clear and show operations from launch to usage on the lunar surface. Power, temperature, pressure, and structural strength are all taken into account, but it would be beneficial to show calculations of how the requirements will be met (for instance, how large the solar panel and battery need to be on each module to meet the power requirements, and how that impacts the module's mass). The rotating floor design for offloading from the rocket is novel but is potentially highly complex, meaning more parts could fail and impact operations. The wide variety of reusability options are superb.
This proposal addresses many environmental factors and is a robust design for a pressurized container. The presentation's graphics clearly show the design and the surface operations. Providing additional calculations (such as for thermal and pressure aspects) would be beneficial to show how the concept meets those requirements. There did not appear to be a hatch interface present with this design, which necessitates full use of an airlock for unpacking. Good information was provided with structural design and material choices.
Good consideration of mechanism design and interfaces with other elements. Design is scalable (variations presented to support additional CTBs). Concept for initial deployment and overall conops is well-presented. Environmental considerations for operation in dusty, vacuum, partial-g environment could be presented more thoroughly..
