NASA 与机智号直升飞机恢复通讯
2023-07-05 17:09:00 by 向世界倾诉爱
在长达 63 天的电子静默之后，NASA 与火星机智号（Ingenuity）直升飞机恢复了通讯。机智号在火星上完成了 51 次飞行任务，执行第 52 次任务时机智号在向地面下降期间与 NASA 中断了通讯。通讯中断的原因是机智号与毅力号漫游车之间隔了一座小山。机智号依赖于毅力号向地球传输数据，天线传输速率只有每秒 100 kilobits，传输到漫游车的主机之后再通过火星轨道探测器传输到地球。重新恢复通讯标志着第 52 次飞行成功完成。根据 NASA 的飞行日志，机智号累计飞行 11.7 公里，总飞行时长约 91.4 分钟。最高飞行高度 18 米。

New computational method facilitates the dense placement of objects inside a rigid container
In 1611, Johannes Kepler—known for his laws of planetary motion—offered a solution to the question concerning the densest possible way to arrange equal-sized spheres. The famed astronomer took on ...
