美国航空航天局(NASA)的“火星科学实验室”(MSL)项目的最初预定成本为15亿美元,就目前来看,其总成本可能超过20亿美元,超支33%~40%。为确保MSL能够在2009年9月发射,喷气推进实验室(JPL)可能在该项目2009财年预算申请2·23亿美元的基础上要求增加1亿~1·5亿美元。MSL项目2008财 NASA's Mars Science Laboratory (MSL) project was originally booked for a cost of $ 1.5 billion, which for now costs more than $ 2 billion and overruns 33% to 40%. In order to ensure that MSL can be launched in September 2009, Jet Propulsion Laboratory (JPL) may request an increase of $ 100 million to $ 150 million on the basis of the project's $ 229 million budget for fiscal 2009.
