美国总会计室(GAO)最近在一份报告中得出结论:航宇局(NASA)严重地低估了“自由”号空间站计划的总费用。NASA和GAO估算金额相差40％。 GAO认为空间站的研制和建造从现在到2000年期间需经费400亿美元,其中包括从1996年底发射入轨后前3年的管理费。按计划空间站的设计寿命为30年,即2027年后空间站寿命结束,加上后27年的管理费,“自由”号空间站计划的总费用将达到1180亿美元。而NASA的估算是:到2000年时共需300亿美元。另外,每年载
In a recent report, the General Accounting Office of the United States concluded that NASA seriously underestimated the total cost of the space station program. The difference between NASA and GAO estimates is 40%. GAO believes that there will be a demand of $ 40 billion for the development and construction of the space station from now until 2000, including the management fee for the first three years after it was launched into orbit at the end of 1996. The projected life of the space station is 30 years, which means that after 2027, the life of the space station is over. With the administration fee after 27 years, the total cost of the space station program of “Liberty” will reach 118 billion U.S. dollars. NASA estimates that by the year 2000, a total of 30 billion U.S. dollars will be needed. In addition, every year
