新华网华盛顿8月3日电（记者任海军）美国航天局3日发表声明说，3家公司今后21个月内将从该局获得总额超过11亿美元的商业合同，用于研发可运送宇航员往返国际空间站的商业“太空巴士”。

Xinhua net Washington August 3 dec（As reporters）The U.S. space agency said in a statement published three days，Three companies 21 months in the future from the total more than $1.1 billion for commercial contract，Used for research and transport astronauts to the international space station's business“Space bus”。

　　声明说，波音公司将获得4.6亿美元用于开发名为CST－100的飞船；太空探索技术公司将获得4.4亿美元用于研发载人版“龙”飞船；内华达山公司将获得超过2.1亿美元的资金，用于开发名为“追梦人”的飞船。

Statement said，Boeing will get $460 million for development of the spacecraft called CST-100；Space exploration technology company will get $440 million for research and development manned version“dragon”spacecraft；Nevada mountain company will get more than $210 million of the money，For development in the name“dreamer”ship。

　　今年5月下旬，“龙”飞船与国际空间站成功对接，成为有史以来首艘造访空间站的商业飞船。“追梦人”类似于迷你航天飞机，预计将在今年进行无人测试。

In late may this year，“dragon”Spacecraft docked with the international space station success，Becoming the first ship to visit space station commercial spacecraft。“dreamer”Similar to the mini space plane，Is expected to be in this year unmanned test。

　　三家公司从航天局商业载人航天促进项目第三轮竞争中胜出，获得合同。在首轮竞争中，美国航天局共拨付价值5000万美元的合同资金；第二轮竞争中，4家公司获得3.15亿美元合同资金。商业载人航天促进项目是一个多阶段的太空技术开发项目，其最终目的是开发出可替代航天飞机运送宇航员往返空间站的航天器。

Three companies from NASA's manned commercial promotion project is the third round of the competition winner，Get contract。In the first round of the competition，NASA were allocated $50 million contract funds；The second round of the competition，Four companies get $315 million contract funds。Commercial manned space promote project is more than a stage of the space technology development project，The ultimate aim is to develop alternative space planes from the spacecraft of the space station astronauts。

　　自航天飞机去年退役后，美国向空间站运送人员和货物均需要“仰仗”俄罗斯。为改变这种状况，美国航天局鼓励私营企业开发“太空巴士”。

Since the shuttle after retired last year，The United States to the space station transport personnel and the goods are needed“Count on”Russia。In order to change this situation，NASA to encourage private enterprise development“Space bus”。
