Special Issue Information

Dear Colleagues,

As the number of on-orbit satellites and debris objects increases, especially with the deployment of large-scale satellite constellations, space is becoming increasingly congested. Uncontrolled growth will severely affect future space activities. Therefore, effective space traffic management (STM) becomes increasingly important to ensure that space remains a safe and stable environment. STM mainly involves the following aspects: space situational awareness, coordinating the movement of spacecraft and other objects, deploying and operating large-scale satellite constellations, avoiding collisions, debris evolution and removal, etc. Additionally, the detection, classification, response and maneuvers of non-cooperative targets are included.

This Special Issue will be dedicated to exploring new perspectives in design and optimization, modeling, navigation, guidance and control in STM, not only including traditional methods but also combining artificial intelligence with traditional methods. All papers comprising new studies and technologies suitable for application in STM are welcomed.

The growing amount of space debris in geocentricorbit poses a significant threat to the future of space operations. To mitigate this problem, current international guidelines state that a satellite should be able to deorbit or insert into a graveyard orbit within 25 years from the end of its operational life. In this context, drag-enhancing devices such as drag sails are currently an active field of research and development because of their ability to make a spacecraft decay from low Earth orbit without the need for any on-board propellant. Drag sails, conceptually similar to solar sails, are thin membranes deployed by a spacecraft at the end of its operational life to increase the area-to-mass ratio and, consequently, atmospheric drag. To be effectively exploited, a drag sail should maximize the surface area exposed to atmospheric particle flow. However, this would require a fully functional three-axis stabilization system, which may either be unavailable or non-functional on an orbiting satellite after years of space operations. To simplify the deorbiting phase, in this paper we propose to use a spin-deployed and spin-stabilized drag sail, which represents a reasonable compromise between simplicity of implementation and deorbiting performance in terms of total decay time. In fact, a spinning drag sail could take advantage of centrifugal force to unfold and of gyroscopic stiffness to maintain an inertially fixed axis of rotation. Numerical simulations accounting for the main perturbation effects quantify the effectiveness of the proposed device compared with an optimal configuration (i.e., a three-axis stabilized drag sail) and a tumbling drag sail.
