最近,从苏联有关当局获悉,90年中期苏联将用能源号重型运载火箭进行暴风雪号航天飞机第三次发射试验。这架不载人航天飞机将与在轨道上运行的和平号空间站对接。 Recently, the relevant Soviet authorities have learned that in the mid-1990’s, the Soviet Union will carry out the third launch of the Blizzard space shuttle with a heavy energy carrier rocket. The unmanned space shuttle will dock with the Mir space station in orbit.
