80年代轰动全球的美国SDI(俗称星球大战计划),随着苏联解体冷战告终,也烟消云散。但是它所开发的各种高新技术,并没有都束之高阁。其中许多仍在继续研究作为他用。用激光推动火箭进入宇宙空间,便是从SDI继承下来的技术之一。 这种技术正在美国进行研究。它利用激光进行照射使其产生等离子体,使像碗一样轻的飞行器飞向天空。一旦研制成功,我们便将对巨 The United States in the 1980s sensational world SDI (commonly known as Star Wars plans), with the end of the Cold War the collapse of the Soviet Union, also vanished. However, all kinds of high and new technologies it has developed have not been shelved. Many of them are still continuing to study for other uses. Using lasers to propel rockets into space is one of the technologies inherited from SDI. This technology is being studied in the United States. It uses a laser to fire it to create a plasma that can fly a light-weight aircraft like a bowl into the sky. Once developed successfully, we will be huge
