“…When the tether physically interacts with the charged particles of the ionosphere in LEO, drag force is generated on the tether. Therefore, this principle is used to deorbit any space object (Hou et al, 2020). The space tethers can be integrated on a spacecraft even before it is launched as an onboard system or attached by a different spacecraft in space.…”

Space debris is positioned as a fatal problem for current and future space missions. Many effective space debris removal methods have been proposed in the past decade, and several techniques have been either tested on the ground or in parabolic flight experiments. Nevertheless, no uncooperative debris has been removed from any orbit until this moment. Therefore, to expand this research field and progressing the development of space debris removal technologies, this paper reviews and compares the existing technologies with past, present, and future methods and missions. Moreover, since one of the critical problems when designing space debris removal solutions is how to transfer the energy between the chaser/de-orbiting kit and target during the first interaction, this paper proposes a novel classification approach, named ET-Class (Energy Transfer Class). This classification approach provides an energy-based perspective to the space debris phenomenon by classifying how existing methods dissipate or store energy during the first contact.

“…However, the traditional rocket propulsion systems used to launch spacecraft are limited by the amount of fuel they can carry, which limits their speed and range. As a result, the electromagnetic launcher (DREL) system can cost-effectively remove debris from space [2]. At the same time, it can allow us to travel at unprecedented speeds while reducing the environmental impact of our mode of transportation.…”

This article provides an overview of electromagnetic acceleration, which involves using a magnetic field to accelerate charged particles, such as ions or electrons, and is widely used in various fields of science and technology. The article describes the principles of electromagnetism and its application in scientific research, transportation, military, and aerospace. It discusses the potential of electromagnetic acceleration to revolutionize high-speed rail travel and space exploration, but also highlights the engineering challenges, particularly regarding the high voltages and currents required to generate the necessary magnetic fields. The article also presents the classification and principles of electromagnetic emission technology, focusing on the three types of electromagnetic launchers: rail, coil, and reconnection. The rail-type electromagnetic launcher is a single-turn DC motor that consists of a pair of parallel metal rails and a sliding armature, while the coil electromagnetic launcher has multiple stages of coils and a transmitter coil or armature. The reconnection electromagnetic launch is a relatively new area of research, and its system consists of a coil with a gap and a magnetic core. Overall, this article provides an in-depth look at the fundamentals of electromagnetic acceleration, its practical applications, and the potential for future research and development.

“…Efforts to address this problem have been varied to date, not only involving active debris removal with robotic arms [21]. Other strategies include the use of large nets [24], tether systems [25], laser ablation [26], and magnetic methods [27]. Drag devices are also in play, aiming to expedite debris reentry into Earth's atmosphere.…”

Aeroelastics-aware compensation system for soft aerial vehicle stabilization

This paper describes a compensation system for soft aerial vehicle stabilization. Balancing the arms is one of the main challenges of soft UAVs since the propeller is freely tilting together with the flexible arm. In comparison with previous designs, in which the autopilot was adjusted to deal with these imbalances with no extra actuation, this work introduces a soft tendon-actuated system to achieve in-flight stabilization in an energy-efficient way. The controller is specifically designed for disturbance rejection of aeroelastic perturbations using the Ziegler-Nichols method, depending on the flight mode and material properties. This aerodynamics-aware compensation system allows to further bridge the gap between soft and aerial robotics, leading to an increase in the flexibility of the UAV, and the ability to deal with changes in material properties, increasing the useful life of the drone. In energetic terms, the novel system is 15–30% more efficient, and is the basis for future applications such as object grasping.
