54、根据第二段第一句可知，自20世纪70年代用于月球任务的美国航空航天局的Saturn 退役以来，Falcon Heavy是当前最大的运载火箭；据此可知，美国航空航天局的Saturn 是运载火箭，故C项正确。2What do we know about Falcon Heavy from the text?AIt is the largest rocket in the world.BIt is of the same load as a 737 jet.CIt is to be found by the creatures in the outer space.DIt was launched
