自1978年苏联核动力卫星在加拿大北部边远地区上空爆炸以来,在宇宙中使用原子反应堆的问题就一直有激烈争论。同时关于使用轨道核装置问题的争论就再度升温。去年四月苏联的另一颗核动力卫星曾因失控而引起人们恐慌;在他们还未能将其推进安全的高轨道之前,反应堆可能降落在地球上。但上月在新墨西哥州举行的一次科学会议上,苏联已宣称他 The use of atomic reactors in the universe has been a subject of intense debate since the Soviet nuclear-powered satellite exploded over remote areas of northern Canada in 1978. At the same time, the debate over the issue of using orbiting nuclear devices is heating up again. Another nuclear-powered satellite in the Soviet Union caused panic in April last year due to loss of control; the reactor could land on Earth before they could push them to a safe high orbit. But at a scientific conference in New Mexico last month, the Soviet Union declared him
