Lunar exploration can benefit from systems developed for low-Earth orbit, as the environmental conditions are overlapping. The development of the CubeSat industry in recent decades has led to a revolution in access to near-Earth space. The goal of Neurospace and its partners is to explore the similarities of both environments for a direct application of existing CubeSat technologies for lunar exploration. Using an open standard and a tiered approach for the development of lunar rovers will allow future missions to focus more on the actual use case rather than the individual development, qualification, and certification of required components. This paper introduces the HiveR rover and provides a classification of the future importance of robotic systems for lunar exploration. It also discusses, in review of past lunar missions, how such rovers differ from previous lunar rovers, and how important they can be in supporting increasingly complex missions. The similarities and differences between the low-Earth orbit and the lunar surface are outlined. Based on this, the new challenges in adapting existing CubeSat technologies for robotics on the lunar surface will be discussed and initial solutions presented. As examples of potential payloads, various experiments are presented, such as a robot arm that was developed to fit in a 1 U volume. It can be used for docking operations between individual systems or various tool handling operations.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"6 2-4","pages":"57 - 72"},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 2D-planar and an axisymmetric intake are investigated using commercial code ANSYS-Fluent. The density gradient for intakes is computed to investigate and compare the shock cell structure and the separation bubble size. Besides, the velocity and pressure distributions are analyzed for planar and axisymmetric intakes. It is observed from the wall pressure data that the shock strength in the case of axisymmetric intake is lesser than the planar intake. Also, the interaction region in the axisymmetric intake is shifted further downstream with a progressive decrease in shock angle. The recirculation zone or the separation bubble size is minimal for the axisymmetric intake than for planar intake, resulting in higher effective mass flow into the combustion chamber. It can be observed that although the cowl surface experiences the maximum wall static pressure, the recirculation zone formed over the cowl surface is comparatively smaller than that of the ramp surface. The normalized total pressures at the isolator exit indicate that the axisymmetric intake is more efficient in conserving the flow energy than the planar intake. The temperature rise over the ramp surface is higher for planar intake; however, the temperature fluctuations over the ramp surface are more for axisymmetric intake.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"6 2-4","pages":"133 - 142"},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the future, long-duration space exploration is planned for the Moon, and, beyond that, to Mars. Food for such extended missions needs a shelf-life of up to 5 years, a sustained nutritional and product quality. Space radiation can impact on such food, but little is known of what impact this could have on these materials. In this study, we evaluated the impact of radiation dosage and accelerated storage on infant milk powder (a formulated product consisting of proteins, fat, lactose, vitamins, and minerals), to evaluate its potential as an indicator for (chemical) space food stability. The milk powder was irradiated at different dosages (0, 2, 10, and 50 kGy) and underwent different storage conditions (20 or 50 °C for 0, 14, 28, 56, and 77 days), with subsequent color measurement and chemical analysis. It was found that <i>γ</i> irradiation had an impact on the milk powder’s color. It was speculated that this change was related to the Maillard reaction. Some changes were also found with the chemical composition, particularly, vitamins A and C, unexpectedly due to their susceptibility to radiation. Notable differences were not observed though for other components (vitamins, fatty acids, and amino acids). We conclude that infant milk powder shows great promise as an indicator of the impact of <i>γ</i> radiation, and accelerated storage, for (chemical) space food stability.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"6 2-4","pages":"117 - 132"},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42423-023-00140-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138588772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The team's success in a national academic CubeSat design competition led to the establishment of a space startup and the decision to develop a 6U platform. The primary motivation for writing this research is to increase access to space and space services by helping startups _especially in underdeveloped countries, design and build a CubeSat with the least cost and effort in the shortest possible time. In the design process, simplicity, reliability, and the possibility of reproduction at the lowest possible cost have been prioritized. Aligned with ECSS standards tailored for CubeSats, the design method parameters of the 6U platform are thoroughly examined. The article highlights the development of a state machine and the justification of design requirements through standard methods and tracking them using RTM and RVTM tables. Effective interface control while using COTS components is emphasized to reduce costs by approximately 50% while ensuring quality and meeting space environment requirements. The architecture of the Pluto platform, comprising entirely of commercial components, is showcased, providing insights into its system characteristics. This systematic design underscores the importance of modularity, affordability, and utilization of COTS components. By sharing their experiences, the Pluto team aims to support space industry startups and inspire innovative CubeSat projects.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"6 1","pages":"1 - 18"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42423-023-00137-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50489956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
