航天技术虽然仅有30余年的历史,但其发展速度和规模都是空前的。美苏两国历年的航天经费占世界各国航天经费总数的95%,发射总数占96%,是目前仅有的具备载人航天能力的国家。两个超级大国航天技术的发展,基本上决定了世界航天技术发展的趋势和格局。航天技术的发展,其导源虽然是苏美两国的争霸,然而30余年的发展,为人类开辟了广阔的空
Although space technology has only a history of more than 30 years, its development speed and scale are unprecedented. The space expenditures of the United States and the Soviet Union for the past year accounted for 95% of the total number of aerospace funds in the world, and the total number of launches accounted for 96%. It is the only country with the capability of manned spaceflight. The development of space technology in the two superpowers basically determines the development trend and pattern of world space technology. The development of space technology, although the source of its leadership is the hegemony of the Soviet Union and the United States, but the development of more than 30 years has opened up a vast space for mankind.
