在一项星际任务中,几乎所有的开发成本都集中在建设定向能发射系统上。探测器本身是一些绑定在反射板上的小型设备,建造成本相对低廉,发射100个探测器几乎与发射一个探测器的成本相当。我们甚至可以建造数以百万计不同质量的探测器,可以是苹果手机尺寸但更薄的“晶圆”飞船,也可以是更大的探测器,但它们均携带复杂的照相机、传感器和一个由小型放射性同位素热电式发电机(RTG)提供动力的激光通信系统。这个RTG类似 In an interstellar mission, almost all of the development costs are concentrated on the construction of directional energy launch system. The detectors themselves are small devices that are attached to the reflectors and are relatively inexpensive to construct and launch nearly 100 detectors at almost the cost of launching one detector. We can even build millions of detectors of different qualities, which can be “thin” but thinner “wafer” spacecraft, but also larger detectors, but all carry sophisticated cameras, sensors And a laser communications system powered by a small radioisotope thermoelectric generator (RTG). This RTG is similar
