“…Currently, there are no clear regulations agreed between the space-faring nations about space debris mitigation, including ASAT [118], apart from non-binding mitigation guidelines from IADC and COPUOS. Therefore, until now, there is a deficiency of the law or international treaty that prohibit testing, deployment, and use of space-based weapons and ASATs [117] for environmental protection.…”

Over the past 60 years, satellite technology has demonstrated its usefulness successfully. However, this usefulness is at stake from a future point of view, due to the well-admitted orbital/space debris threat. This article thoroughly reviews all aspects of space debris issue including causes, amount and sizes of orbital debris, potential threats, counter-strategies with their latest status and related legal issues to highlight the criticality and urgency of the problem. This review elaborates the fact that despite all the worries and threats, the efforts to confront this challenge are considerably insufficient until today. This bitter reality demands for at-least curtailing the number of future launches to ensure the long-term sustainability of space, until the improvement in debris situation. However, contradictory to this necessity, large satellite constellations have been proposed that can drastically increase the existing orbital population in coming years. This approach will certainly not help in improving the space environment in the future; instead, it can worsen the space environment situation as recent studies shows. Also, space resources (i.e. orbital slots and frequencies) are limited to accommodate many more satellite projects from commercial and government organization in the future. So, there is a serious question of how the space industry can move forward to maintain a balance in controlling the future number of the satellite while accommodating many commercial or government space entities. This article also identifies two optimized approaches as a way forward for future satellite projects that can also enhance the effectiveness of space technology in the future.

“…Collisions with such debris are the primary sources of spacecraft fragmentation, leading to the generation of additional space debris and contributing to an increasingly congested orbital environment [1]. As a result, mitigating space debris has become a top priority for the international space community, necessitating the implementation of effective strategies to reduce the accumulation of space debris and ensure the safety of space operations [2]. Mathematical modelling of this phenomenon is very challenging due to the high velocities involved and the large energies generated during impact.…”

Abstract. Spacecraft fragmentation due to collisions with space debris is a major concern for space agencies and commercial entities, since the production of collisional fragments is one of the major sources of space debris. It is in fact believed that, in certain circumstances, the increase of fragmentation events could trigger collisional cascade that makes the future debris environmental not sustainable. Experimental studies have shown that the fragmentation process is highly complex and influenced by various factors, such as the material properties, the velocity and angle of the debris impact and the point of collision (e.g. central, glancing, on spacecraft appendages). In recent years, numerous impact tests have been performed, varying one or more of these parameters to better understand the physics behind these phenomena. In this context some tests have been also performed at the hypervelocity impact facility of the university of Padova. This paper provides an overview of the main experiments performed, the most critical issues observed and proposes some future directions for further research. Moreover, it summarizes the current state of research in spacecraft fragmentation, including the methods and techniques used to simulate debris impacts, the characterization of fragment properties and the analysis of the resulting debris cloud.

“…The formation of smaller debris would rapidly increase with the number of collisions in regions where the SD density reached a critical density, Kessler [1].Accordingly to data from January 2018, the US SPACE SURVEILLANCE NETWORK [2,6] currently monitors about 19,000 objects larger than 10 cm; 200,000 objects between 1 and 10 cm; and more than 330 million objects smaller than 1 cm [7]. The risk of accidents with space debris is determined mainly by three factors: time in orbit, speed, and difficulty in elimination [3].…”

Space Debris (SD) is the by-product of space missions and Earth's gravitational capture in the dynamics of the Solar System. Their accumulation in this environment constitutes a real and permanent risk for these missions. Mathematical and computational analysis for the relative dynamics between SD and a space vehicle, considering the Earth's gravitational and propulsion forces, is performed in this work. Exhaustive numerical simulations of the model were performed for suboptimal technological parameters (power factor, exhaust speed) and physical parameters (start and duration of propulsion) suitable for evasive maneuvers for minimum fuel consumption and relative distance accuracy. The simulation results identify important patterns that help us understand the characteristics of space vehicle propellant control parameters for evasive maneuvers.
