Background

Africa's engagement in space sciences and space systems is rapidly evolving, presenting both significant challenges and immense opportunities. This article explores the current state of African space endeavors, highlighting the limitations imposed by infrastructural deficiencies, limited funding, and lack of skilled workforce. Despite these hurdles, considerable potential exists in leveraging space technology for socio-economic development across the continent, particularly in agriculture, disaster management, telecommunications, and resource management. Opportunities include fostering regional collaborations, attracting international partnerships, and investing in education and training programs to cultivate a robust space sector.

Methodology

This article uses multifaceted techniques including multi-criteria decision analysis, case study and structured review to identify the current space governance gaps in Africa, raise awareness of Geoinformatics, Open Science (OS), and Artificial Intelligence (AI), in achieving sustainable space governance in Africa, and cater for a decision support framework including through as proposed African governance model, capacity development, implementation plan and roadmap to further African Union’s Agenda-2063.

Findings

This work highlights the need for a concerted effort to develop comprehensive national space policies, promote private sector participation, and establish sustainable funding mechanisms to ensure the long-term success and impact of African space systems. A focus on capacity development and the development of indigenous technologies, building a solid regulatory framework, and enhancing satellite infrastructure, would be crucial for achieving self-reliance and maximizing the benefits derived from space exploration and application across the diverse African landscape.

The establishment of long-term lunar bases requires an advanced understanding of human adaptation to extreme environments, including isolation, hypobaric hypoxia, and confinement in small habitation spaces. This review combines the methodological design and organisational features of a year-long study conducted during the 64th Russian Antarctic Expedition at Vostok Station in Central Antarctica, which serves as a valuable terrestrial analogue for lunar habitat investigations. By examining the cardiorespiratory and autonomic nervous system adaptations of 11 expeditioners in hypobaric hypoxia and isolation environments, we addressed some of the essential gaps in space medicine regarding small-sample longitudinal design studies and will serve as a guide for future lunar mission protocols. In this review, we summarised information from open-source literature and our own experience in planning and conducting a comprehensive investigation in one of the harshest locations on the planet.

Trajectory optimization problem of the motion of a service spacecraft designed to remove space debris from the vicinity of geostationary orbit has been examined in the present paper. It is assumed that the service spacecraft is equipped with a radio-frequency ion source. The selected space debris is removed from the protected area under the influence of the mechanical action of the ion beam. The corresponding problem of end-to-end trajectory optimization is considered to assess the maneuvering capabilities of a service spacecraft during a series of successive interorbital flights, as well as the amount of space debris removed by ion beam. A general methodological approach to solving the problem has been determined, and a set of necessary conditions for optimality has been obtained.

The proliferation of space debris and defunct spacecraft has dramatically increased on-orbit collision risks. The demand for precise capture and deorbiting of non-cooperative targets is becoming increasingly urgent. However, factors such as target unknownness, the extreme complexity of the space environment, and real-time communication limitations severely constrain the accuracy and success rate of existing capture technologies. To address this, this paper proposes an automated capture process methodology based on multimodal information fusion. This method establishes a closed-loop technological workflow encompassing "Target Identification - Strategy Formulation - Capture and Grasping". Specifically, it extracts task intent through lightweight text parsing, enhances decision accuracy by synergizing visual and spatial information, and drives robotic arms for precise control. Simulation experiments confirm that the method exhibits strong robustness against perturbations and maintains reliable performance across diverse benchmark scenarios. Beyond technical improvements, the proposed framework enhances real-time autonomy, reduces the risk of collision-induced fragmentation, and supports long-term orbital sustainability in line with international debris mitigation guidelines.

空间碎片和报废航天器的扩散大大增加了在轨碰撞的风险。精确捕获非合作目标并使其脱离轨道的需求日益迫切。然而，目标不可知、空间环境的极端复杂性、实时通信限制等因素严重制约了现有捕获技术的准确性和成功率。为了解决这一问题，本文提出了一种基于多模态信息融合的自动捕获过程方法。该方法建立了一个包含“目标识别-策略制定-捕获和抓取”的闭环技术工作流程。具体而言，它通过轻量级文本解析提取任务意图，通过协同视觉和空间信息提高决策精度，并驱动机械臂进行精确控制。仿真实验证实，该方法对扰动具有很强的鲁棒性，并在不同的基准场景中保持可靠的性能。除了技术改进之外，拟议的框架还增强了实时自主性，减少了碰撞引起碎片的风险，并根据国际碎片缓减准则支持轨道的长期可持续性。

The objective of this analysis is to identify systemic factors that may affect the safety and mission performance aspects of Flight Safety Systems, including Flight Termination Systems, through the application of System-Theoretic Process Analysis, a hazard analysis technique based on the System-Theoretic Accident Model and Process approach that is capable of detecting potentially hazardous design and operational weaknesses, including interactions among multiple procedures and system components. This analysis identifies losses, hazards, safety constraints, hierarchical control structures, unsafe control actions, possible loss scenarios, and associated causal factors. It proposes safety recommendations that can be adopted for each identified loss scenario. These recommendations aim to avoid unsafe actions and undesired system behaviors or even to mitigate their consequences. They can be utilized to improve space systems design, launch vehicle systems, ground support equipment productions, launch vehicle operations, and launch approval regulations.

本分析的目的是通过应用系统理论过程分析，识别可能影响飞行安全系统（包括飞行终止系统）安全和任务性能方面的系统因素，系统理论过程分析是一种基于系统理论事故模型和过程方法的危害分析技术，能够检测潜在的危险设计和操作弱点，包括多个程序和系统组件之间的相互作用。该分析确定了损失、危害、安全约束、分层控制结构、不安全控制行动、可能的损失情景以及相关的因果因素。它提出的安全建议，可采用的每一个确定的损失情况。这些建议旨在避免不安全的操作和不希望的系统行为，甚至减轻其后果。它们可用于改进空间系统设计、运载火箭系统、地面支持设备生产、运载火箭操作和发射批准规定。

Extravehicular Mobility Units (EMUs) constitute vital life-support systems for astronaut operations in extraterrestrial environments. Apollo mission data confirm lunar dust as the primary operational hazard during lunar surface extravehicular activities. Contemporary research on active dust mitigation predominantly targets electrostatic systems, mechanical-electrostatic hybrids, and fluid-based methodologies. This review systematically assesses active dust removal technologies for spacesuits, focusing on fluid-based methodologies, mechanical, and electrostatic approaches. While fluid-based methodologies demonstrate superior overall dust removal rates and effectiveness across a broader particle size range, their application in extraterrestrial environments is severely constrained by fluid dispersion in vacuum, resource consumption, and potential contamination. Electrostatic techniques, particularly electrodynamic systems, offer non-contact operation and significant future potential but currently face challenges including high power consumption, reliance on high voltages, and limited efficiency in removing sub-micron particles. Mechanical methods, valued for their reliability and simplicity in handling large particles, were successfully employed in the Apollo program. However, they struggle with fine dust, pose abrasion risks to sensitive surfaces, and exhibit performance variability under different gravitational and pressure conditions. Future research should prioritize overcoming the high-voltage dependency of electrostatic methods through innovative electrode designs and hybrid excitation strategies. Fluid-based methodologies show promise when reconfigured for controlled, enclosed environments like lunar base dust removal chambers, enabling resource recovery and sustainable operation. Mechanical systems require evolution beyond traditional brushing via miniaturization, force-controlled actuators, and integration with electrostatic or vibrational components for enhanced efficiency and reduced wear. Ultimately, the development of hybrid solutions, combining the strengths of these technologies, and advancing materials for self-cleaning surfaces, is crucial for achieving effective, adaptive, and integrated dust mitigation strategies essential for long-term extraterrestrial missions.

舱外活动单元（emu）是航天员在地外环境中活动的重要生命支持系统。阿波罗任务数据证实，月球尘埃是月球表面舱外活动的主要操作危害。当代对主动粉尘缓解的研究主要针对静电系统、机械-静电混合动力和基于流体的方法。本文系统地评估了宇航服的主动除尘技术，重点是基于流体的方法，机械和静电方法。虽然基于流体的方法在更大的粒径范围内显示出优越的总体除尘率和有效性，但它们在地外环境中的应用受到真空中流体分散、资源消耗和潜在污染的严重限制。静电技术，特别是电动力系统，提供了非接触操作和巨大的未来潜力，但目前面临的挑战包括高功耗，对高压的依赖，以及去除亚微米颗粒的效率有限。机械方法在处理大颗粒时因其可靠性和简单性而受到重视，成功地应用于阿波罗计划。然而，它们与微细粉尘作斗争，对敏感表面造成磨损风险，并且在不同的重力和压力条件下表现出性能变化。未来的研究应优先考虑通过创新电极设计和混合激励策略来克服静电方法的高压依赖性。当重新配置流体方法用于受控、封闭的环境（如月球基地除尘室）时，可以实现资源回收和可持续运行。机械系统需要通过小型化、力控致动器以及与静电或振动组件集成来提高效率和减少磨损，从而超越传统的刷刷系统。最终，开发混合解决方案，结合这些技术的优势，以及先进的自清洁表面材料，对于实现长期地外任务所必需的有效、自适应和综合减尘战略至关重要。

This study examines the effects of resonance on the orbital elements of space debris whose mean motion is commensurable with Earth’s rotation. By applying a suitable sequence of canonical transformations, the system of differential equations describing the orbital motion is reduced to an integrable kernel. Focusing on a specific resonant angle, numerical simulations are conducted to demonstrate the variations in the orbital elements of space debris orbiting near the

resonance, specifically in LEO orbit at altitudes ranging from 559 km to 563 km. The study reveals that the motion in the vicinity of the exact resonance region is highly sensitive to minor perturbations and that the resonance effect occurred primarily in near-circular orbits and at high inclinations where the effect of the Earth non-sphericity (

) has low influence This sensitivity suggests that these regions may exhibit chaotic behavior or lead to collision-prone orbits considering different initial conditions.

本研究探讨共振对平均运动与地球自转可通约的空间碎片轨道要素的影响。通过适当的正则变换序列，将描述轨道运动的微分方程组简化为可积核。针对特定的共振角度，进行了数值模拟，以展示在15:1共振附近轨道运行的空间碎片轨道要素的变化，特别是在高度为559 km至563 km的LEO轨道上。研究表明，精确共振区域附近的运动对微小扰动高度敏感，共振效应主要发生在近圆轨道和高倾角轨道上，而地球非球性（J2）的影响较小。这种敏感性表明，考虑不同的初始条件，这些区域可能表现出混沌行为或导致容易碰撞的轨道。

This paper develops a LIDAR-based landing site risk map generation and safety estimation technique for autonomous space vehicles to develop a feature extraction method for rendezvous and docking applications and to generate a Digital Elevation Model of ground points using PDAL. The open source C / C++ library and the Point Data Abstraction Library software program, or PDAL, are used to translate, filter and analyze point-cloud data, including a LIDAR point-cloud dataset. There are many software programs available; however, they are neither flexible nor simple to integrate. By offering abstract access, filtering, exploitation, and workflow management features in an open-source package, PDAL bridges the gaps in spatial point-cloud software. These platforms allow us to produce reference models that are helpful for applications related to landing, rendezvous, and docking. The algorithm is developed and validated using an Aerial Laser Scanner dataset.

本文开发了一种基于激光雷达的自主航天器着陆点风险图生成和安全估计技术，为交会对接应用开发了一种特征提取方法，并利用PDAL生成了地面点的数字高程模型。使用开源的C / c++库和点数据抽象库软件程序（PDAL）来翻译、过滤和分析点云数据，包括激光雷达点云数据集。有许多软件程序可用；然而，它们既不灵活，也不容易集成。通过在一个开源包中提供抽象的访问、过滤、利用和工作流管理功能，PDAL弥补了空间点云软件的不足。这些平台允许我们生成参考模型，这些模型有助于与着陆、交会和对接相关的应用。利用航空激光扫描仪数据集开发并验证了该算法。

The need for a strict interpretation of legal instruments to ensure effective international cooperation 需要严格解释法律文书，以确保有效的国际合作

The space sector has always been seen as an ideal way of fostering cooperation between states, and the International Space Station (ISS) has long been proof of this. But the geopolitical situation is deteriorating, and with it the legal context. One of the culprits: misinterpretation of the terms of space treaties. A treaty must be interpreted in the same way by all States, otherwise it will generate tensions and conflicts. In this paper, after an overview of the issues regarding interpretation of international treaties, we will examine five central questions of international space law: the placement of nuclear weapons in outer space, the principle of non-appropriation regarding resources exploitation, militarisation of outer space, the meaning of the word “astronaut” and finally, the boundary between airspace and outer space. We look at these examples, without providing any answers, and argue that the terms should be defined when the treaties are negotiated.

空间部门一直被视为促进国家间合作的理想方式，国际空间站（ISS）早就证明了这一点。但地缘政治形势正在恶化，法律环境也随之恶化。罪魁祸首之一：对太空条约条款的误解。所有国家都必须以同样的方式解释条约，否则就会产生紧张和冲突。在本文中，在概述了有关国际条约解释的问题之后，我们将研究国际空间法的五个核心问题：在外层空间放置核武器，关于资源开发的不占有原则，外层空间军事化，“宇航员”一词的含义，最后是空域和外层空间之间的边界。我们看了这些例子，没有给出任何答案，并认为这些条款应该在谈判条约时定义。
