“…The generated debris is the calculation input for sequence optimization. In this article, based on the orbital parameters of the debris removal platform, the Monte Carlo random sampling method is used to construct the orbital elements of the initial space debris near the production platform orbit in Equations (1) and (2) [24]. Based on the introduction above, the process of a space-energy driven laser-ablation debris removal system is as follows:…”

The space-energy driven laser-ablation debris removal technology can remove or detach multiple centimeter-level space debris in a single mission. However, the space-energy driven platform can only rely on its own equipment capabilities to detect and identify space debris. It is necessary to select multiple potentially removable debris targets to improve the removal efficiency. In this paper, target selection for a space-energy driven laser-ablation debris removal system is analyzed based on ant colony optimization. The intersection and interaction periods were given by the optimal driving sequence calculation for multiple debris. Parameters such as the detection range, pulsed energy, repetition frequency of the laser and trajectory of debris have been considered as inputs of the simulation. Target selection and optimal action time have been calculated when a single debris entered the detection range of the laser system. This optimization can significantly improve the overall efficiency and laser energy utilization of the space-based laser platform for the same randomly generated debris group, compared to the mode driven sequentially according to the order of entering the laser action range. The results showed that after being filtered by the ant colony algorithm, the number of removable debris doubled, and the de-orbit altitude increased by 15.9%. The energy utilization rate of the laser removal system has been improved by 74.6%. This optimization algorithm can significantly improve the overall work efficiency and laser energy utilization rate of the space-energy driven system. It can remove more debris or have a larger effective orbit reduction distance value for all debris.

“…LEO's congestion makes it stand out against a worrying scenario, given that it is located right after the planet leaves for space and gives access to the other orbits. However, it is stated in [6] that it is currently characterized as the Earth's orbit more congested in that among all the space objects cataloged up to the 40 thousand km of altitude, 75% are in LEO. Not only is the huge growth in the amount of space junk, the number of launches each year and the ability of rockets to carry more and more satellites as well makes orbits more congested, in terms of satellite and spacecraft traffic.…”

Space debris are all objects created by man that are in Earth orbit but that do not perform any function, being a problem for polluting the extraterrestrial environment, bringing risks to satellites and operational ships. Solar sail technology, which uses the Sun as a sustainable energy source, is a strong tool for removing objects from space located in low Earth orbit (LEO), which is currently the most congested. To validate the use of the solar sail as a space debris mitigation method, we performed numerical simulations of the orbital motion to prove the decay of the perigee radius (r_p) over the years. Based on current technological parameters, we note, therefore, that the solar sail is efficient in this function.
