The space activities in almost every orbital regime are now jeopardized by the continuous growth of the space debris populations. To prevent the proliferation of the space debris in Earth orbit it is necessary to tackle the problem from dierent perspectives, exploiting the latest theoretical and experimental knowledge in dierent elds, such as astrodynamics, spacecraft engineering and legal studies, to address four main pillars: prevention, protection, mitigation and regulation. In this respect the European Community nanced a large H2020 project named ReDSHIFT whose goal is to nd passive means to mitigate the proliferation of space debris. A short summary of the project and of its main ndings is given in the paper, with particular emphasis on the more theoretical part, related to the simulation of long term evolutionary scenarios of the whole space debris environment and to the mapping of the Low Earth Orbit phase space, looking for passive dynamical de-orbiting solutions.

In this paper, we investigate a practical strategy for de-orbiting the retired satellite in low-Earth orbit for the space debris mitigation. The only means available onboard the spacecraft for performing the task is the chemical propulsion system with limited propellant provided. It is proposed to reduce the orbital perigee to reach a certain level where the atmospheric drag can play its role in lowering the satellite altitude, and eventually bringing it to re-entry within a defined period of time. The required delta-V is divided into a series under the constraints on the propulsion system and orbit control manoeuvre implementation. The results from the flight dynamics simulator suggest that a fraction of the remaining propellant available on the demonstrating mission, the Thaichote satellite, would be sufficient to accomplish the task. The strategy implementation will be another vital step in transferring the spacecraft to a safe passive state, where the fuel tank is empty, all batteries are discharged and all electronic devices are deactivated.

Space debris is a global mounting ultimatum to the enduring maintainability of outer space activities and ought to be managed from the very beginning; otherwise, it will be too late. Based on the last couple of years, collisions are incidents that have enhanced space debris accumulation, and the rate at which space activities have resulted in the production of debris is at a threshold position in a linear fashion. Ultimately, space has become the rendezvous of space debris. Based on the growing accumulation of debris and the emerging apprehension regarding a horrible strike and collapse of whole space programs, to remove debris is very expensive process so this paper focuses on the financial challenges and solution as well. Developing and developed countries realize the value of a competent establishment of an International Fund for Debris Mitigation and Removal (IFDMR) that could address the financial issues. Thus, this paper suggests to create incentive opportunities for remediation of space debris and penalties for its production. it would be very strong and effective mechanism to halt this mounting issue by utilizing international fund. The revenue for fund would be collected mainly from contributing member states space agencies, the proportionate contributors of debris producer like (US, RUSSIA, CHINA), and other relevant stack holders, insurance of missions, levying fee from every launching, donations from various international organizations and private entities and UN Aid etc. The fund would be operated by the Director of fund having board of directors as management team under the umbrella of UNOOSA.

Human space activities have grown rapidly in recent decades, but the international legal framework, comprising of the five space treaties, has largely remained unchanged since the 1980s. One of the consequences is that international responsibility and liability for space debris, which is a major hazard to space activities, have also remained uncertain for years. Nonetheless, States have responded to these problems by implementing national voluntary measures. More importantly, two major non-binding international instruments have been laid down by the Inter-Agency Space Debris Coordination Committee and the United Nations Committee on the Peaceful Uses of Outer Space, respectively. This article argues that, in light of recent States practice established under these international instruments, and a proper interpretation of the space treaties, it has been recognised by the international community that States are obliged to mitigate the generation of space debris, a failure of which will lead to international liability.

AbstractA simple dynamic model to investigate the relative fluxes and particle velocities on a spacecraft’s different faces is presented. The results for LDEF are consistent with a predominantly interplanetary origin for the larger particulates, but a sizable population of orbital particles with sizes capable of penetrating foils of thickness <30μm. Data from experiments over the last 30 years do not show the rise in flux expected if these were space debris. The possibility of a population of natural orbital particulates awaits confirmation from chemical residue analysis.

So-called “space junk” forced a change of plan for a recent Shuttle mission. However, ground-based lasers with atmospheric-turbulence-compensating beam directors represent a singularly effective method of de-orbiting space junk, because they use cheap Earth-based power, and because they lend themselves to rapid retargeting. Plasma physics and lasertarget interaction theory dictate the laser parameters for a particular mission. We will discuss a practical laser system and beam director with 20-kW average power at 0.5-µm wavelength that is capable of clearing most low-Earth-orbit objects with mass less than 100 kg in about 4 years. This is a special application of the Laser Impulse Space Propulsion (LISP) concept, by which objects are propelled in space by the ablation jet produced on their surface by a remote laser.
