美国科学家设计出一种如昆虫般大小、只有十几克重的微型卫星。这种卫星的控制器是模拟低等动物的神经细胞制成的，在接收到信号后会产生脉冲，就像动物本能的“抽搐”反应一样。由于造价低廉，它可以批量生产。它们还能协同工作完成庞大的传统卫星难以完成的任务，比如对地球 Scientists in the United States have designed a microsatellite of insect size that is only a dozen grams. The satellite’s controller is made of neurons that mimic lower animals and will pulse when it receives a signal, just like the animal’s instinctive “twitching” response. Because of its low cost, it can be mass-produced. They can also work together to accomplish tasks that are difficult for large, traditional satellites, such as Earth
