日本企业将为富人打造人工流星雨专家：这样不好

尽管如此，人造流星雨仍然会对间谍卫星产生影响，因为这些卫星无法追踪，而且会在低至158英里（254千米）的高度运行。

Low-earth orbit (that is, anything under 2,000 km from the Earth's surface) is also slated to become a lot busier in the coming years, Seitzer told Buzzfeed.

赛策尔告诉BuzzFeed网站说，近地轨道（距离地表2000千米以内）在未来也将变得更加繁忙。

Indeed, there are plans in the works that suggest low-earth orbit is about to become a lot more crowded. SpaceX and other companies plan to send up a number of satellites to establish satellite-based internet services; SpaceX alone plans to put over 4,000 of them between 700 and 900 miles (1,100 and 1,400 kilometers).

目前正在实施的计划显示，近地轨道确实将变得更拥挤。SpaceX和其他公司计划发送多颗人造卫星来建立基于卫星的网络服务；SpaceX公司还计划将4000多颗卫星放在700至900英里间的高度（1100到1400千米之间）。

There are also the high-speed rockets and space planes that companies plan to fill with tourists, and low-altitude spacecraft that the military wants to use to deliver yet more satellites.

多个公司还计划让游客乘坐高速火箭和航天飞机上天，军方则希望通过低空飞行器运送更多卫星。

Add thousands of falling metal pellets to the 500,000 pieces of man-made debris we already know circle our planet, and the risk for any of these spacecraft becomes significantly higher.
