为了纪念哥伦布1492年发现新大陆500周年,美国发起以月球为目标的太空帆船航天比赛,向世界各国招标太空帆船方案。美洲、亚洲、欧洲三大洲各评选出一个最佳方案,研制成三艘太空帆船,于1992年同时发射升天,然后借助太阳风吹动太空帆进行航天,予计要经历四百五、六十天时间,可以抵达月球,或者在月球附近飞过,以最先到达、最接近月球者为优胜。 In commemoration of Columbus’s discovery of the 500th anniversary of the New World in 1492, the United States launched a space-based spacecraft spaceflight program aimed at the moon and bidding for space sailing programs to various countries in the world. The Americas, Asia and Europe each selected one of the best options for the development of three spaceships. They launched the astronaut simultaneously in 1992 and then used the solar wind to propel the spacecraft into space. It is estimated to take 450 to 60 days Time, you can reach the moon, or fly in the vicinity of the moon, to reach the first, the nearest to the moon is the winner.
