“…It is worth noting that the context information is essential for vision understanding and analysis. (2) The high sensitivity to registration errors: as SR fuses all the image patches, all the image patches need to be accurately registered. However, image registration itself is also a difficult task and the registration error may exist all the time.…”

The increasing amount of space debris in recent years has greatly threatened space operation. In order to ensure the safety level of spacecraft, space debris perception via on-orbit visual sensors has become a promising solution. However, the perception capability of visual sensors largely depends on illumination, which tends to be insufficient in dark environments. Since the images captured by visible and infrared sensors are highly complementary in dark environments, a convolutional sparse representation-based visible and infrared image fusion algorithm is proposed in this paper to expand the applicability of visual sensors. In particular, the local contrast measure is applied to obtain the refined weight map for fusing the base layers, which is more robust in a dark space environment. The algorithm can settle two significant problems in space debris surveillance, namely, improving the signal-noise ratio in a noise space environment and preserving more detailed information in a dark space environment. A space debris dataset containing registered visible and infrared images has been purposely created and used for algorithm evaluation. Experimental results demonstrate that the proposed method in this paper is effective for enhancing image qualities and can achieve favorable effects compared to other state-of-the-art algorithms.

“…With the continuous development of space exploration technology, the potential risks caused by space debris orbiting the Earth have become increasingly prominent [1][2][3]. Among them, centimeter-scale debris from 1 to 10 cm in size are called most dangerous space debris, because neither active evasion nor structural protection can be used when dealing with them.…”

“…In addition, high-power laser technology research for the destruction of space debris has been going on for many years. Fang et al [3] proposed a spacebased nanosecond pulse laser to remove centimeter-scale debris near the International Space Station, but there are still some problems with this technology that need to be solved such as low energy conversion efficiency. Currently, the development of high-power pulse technology has made it feasible for spacecraft to generate MeV-range relativistic electron beams.…”

In recent years, it has been proposed to use satellite-mounted radio-frequency (RF) accelerators to produce high-current relativistic electron beams to complete debris removal tasks. However, when simulating the long-range propagation (km-range) process of the electron beam, it is difficult to directly use the particle-in-cell method to simultaneously consider the space charge effect of beam and the influence of the geomagnetic field. Owing to these limitations, in this paper, we proposed a simplified method. The ps-range electronic micropulses emitted by the RF accelerator were transmitted and fused to form a ns-range electron beam; then, combined with the improved moving window technology, the model was constructed to simulate the long-range propagation process of the relativistic electron beam in near-Earth environment. Finally, by setting the direction of movement of the beam to be parallel, perpendicular and at an inclination of 3°to the magnetic field, we analyzed and compared the effects of the applied magnetic fields in different directions on the quality of the beam during long-range propagation. The simulation results showed that the parallel state of the beam motion and magnetic fields should be achieved as much as possible to ensure the feasibility of the space debris removal.

“…High-power laser systems for destroying space debris have been studied for over 20 years. Recently, a spacebased nanosecond pulse laser was investigated to remove centimeter-scale space debris near the International Space Station (ISS) (Fang et al 2019). The use of a tall groundbased tower equipped with a powerful laser has also been discussed (Calabro and Perrot 2019).…”

The increase in space debris orbiting Earth is a critical problem for future space missions. Space debris removal has thus become an area of interest, and significant research progress is being made in this field. However, the exorbitant cost of space debris removal missions is a major concern for commercial space companies. We therefore propose the debris removal using electromagnetic launcher (DREL) system, a ground-based electromagnetic launch system (railgun), for space debris removal missions. The DREL system has three components: a ground-based electromagnetic launcher (GEML), suborbital vehicle (SOV), and mass of micrometer-scale dust (MSD) particles. The average cost of removing a piece of low-earth orbit space debris using DREL was found to be approximately USD 160,000. The DREL method is thus shown to be economical; the total cost to remove more than 2,000 pieces of debris in a cluster was only approximately USD 400 million, compared to the millions of dollars required to remove just one or two pieces of debris using a conventional space debris removal mission. By using DREL, the cost of entering space is negligible, thereby enabling countries to remove their space debris in an affordable manner.
