“…The derivative Breakthrough Starshot program uses the same technology, but focuses on the waferscale spacecraft and the ground-based array option. Laser systems have also been considered to characterize and intentionally remove orbital space debris in recent years (Lejba et al, 2018;Wang et al, 2016;Hou et al, 2016). In all of these cases, the DE beam has sufficient flux to cause damage to active Earth-orbiting satellites, which may be inadvertently illuminated.…”

High power Earth and orbital-based directed energy (DE) systems pose a potential hazard to Earth orbiting spacecraft. The use of very high power, large aperture DE systems to propel spacecraft is being pursued as the only known, feasible method to achieve relativistic flight in our NASA Starlight and Breakthrough Starshot programs.In addition, other beamed power mission scenarios, such as orbital debris removal and our NASA program using DE for powering high performance ion engine missions,

Abstract. According to the data we have consulted, we can come to the conclusion that there are five kinds of commonly used methods to get rid of space junk, respectively Laser Removal Technology, Satellite Debris Collector, Space Garbage Truck, Suicide Satellite and Resistance-increase Device. Their respective advantages and disadvantages are different, in this paper, through the establishment of the AHP model, we analyze the different combinations, and get the conclusion of the top three. These schemes can make automatic space debris removal device having a better use value and market competitiveness.

“…In the 2D system, the equation describing the control problem concerning the base can be stated as follows: (15) where forces acting on the eight cold gas thrusters (the outputs) are: (16) and: F x , F y -resultant forces, respectively in x and y direction in the base reference frame (components of F s in 2D case), τ z -a torque with respect to the z direction (component of H s in 2D case), A 3x8 -a matrix transposing forces at 8 cold gas thrusters to resultant force and torque.…”

“…Nets [4] [29] and harpoons [9] are also considered to capture objects on the orbit. Space debris deorbitation may also be accomplished by a precisely aimed laser beam, which creates a cloud of evaporated material slowing down the object and finally causing its re-entry [16], [41].…”
