Space Debris Removal for a Sustainable Space Environment
At the same time when outer space activities become increasingly important to states, the room for actions and new actors tends to get smaller and the risk that outer space becomes inaccessible is rising. Decisionmakers have recently taken the topic of space sustainability on their agenda, investigating policies to coordinate future actions. Nevertheless, they are ignoring the danger that alrea...
متن کاملUpdated Results on the Long-term Evolution of the Space Debris Environment
The long-term evolution of artificial debris in earth orbit has been analyzed, taking into account a detailed traffic model, explosions, collisions and the effects of air drag. Several scenarios, most of them implementing mitigation measures discussed at international level, have been simulated over a 200-year time span. Moreover, the sensitivity of the results to different collision model assu...
متن کاملModelling the evolution of the space debris population
The current space activities are already disturbed and jeopardized by the growing number of orbiting debris. Those planned for the near future, such as the launch of large satellite constellations and the construction of the international space station, are even more sensitive to the evolution of the space environment. Therefore, a clear picture of the present situation in Earth orbit and its f...
متن کاملLong Term Evolution of the Space Debris Population
In the last few years two diierent computer models have been developed in Pisa to study the evolution of the debris population. With them it is possible to simulate diierent scenarios for the future launch policies. We have deened a reference case which is a reasonable forecasting of the future space activities. Based upon it we have performed a number of simulations to study the innuence of th...
متن کاملModelling the Space Debris Evolution : Two New Computer
Two computer codes to simulate the long term evolution (100 years) of the Earth orbiting debris have been developed under a contract of the Euro-pean Space Agency. In one of them, called Semi Deterministic Model (SDM), the goal was to accurately follow the orbital evolution of the population, so that each large object (and a sample of the small particles) is individually propagated with a semi-...
