凯斯勒综合症（通过级联碰撞使轨道物体的数量急剧增加）对未来的空间飞行任务构成严重威胁。为了了解其影响和研究各种碎片减缓战略的有效性，我们使用蛮力计算方法开发了一个最先进的近地环境演变模型。该模型在模拟期间（100多年）以高时间分辨率传播并监测轨道上的每个物体。为了满足所需的计算能力的需求，该模型被实现为LLNL的高性能超级计算机上的并行计算机代码。在这里，我们描述了模型的细节，并提出了模拟的结果。
The Kessler Syndrome (runaway increase in the number of orbiting objects through cascading collisions) presents a serious danger to future space missions. To understand its implications and study the effectiveness of various debris mitigations strategies, we developed a state-of-the-art evolutionary model for the near-Earth environment using the brute force computational approach. The model propagates and monitors every object in orbit at high temporal resolution for the length of simulation (100+ years). To meet the demand of the required computational power, the model is implemented as a parallel computer code on LLNL’s high-performance supercomputers. Here we describe the details of the model and present the results of the simulations.
