WASHINGTON, Feb 28 (Reuters) - The head of the International Monetary Fund
said on Friday that there was no need to "panic" in terms of delivering
economic aid to Ukraine, as she cast doubt the nation would need as much
immediate help as its new leaders claim.
"We do not see anything that is critical, that is worthy of panic at the
moment," IMF Managing Director Christine Lagarde told reporters. "We would

发帖数: 674 | 11 美国航空航天局(NASA)本周二宣布，在运送美国宇航员到国际空间站(International
Space Station)项目的竞争中，波音(Boeing)和太空探索技术公司(Space Exploration
Technologies Corporation)成为了赢家。
此举反映了NASA载人航天计划中的一个根本性转变，即把设计和运行航天器的任务外包
给私人企业，而不是像以往那样亲力亲为。
“我们有可靠的计划，让这两家公司能如期提供服务，”在本周二的新闻发布会上，
NASA的商业乘务计划经理凯瑟琳·吕德斯(Kathryn Lueders)表示。“我们不会为了实
现那个目标而罔顾机组人员的安全。”
波音公司获得了一份42亿美元（约合人民币258亿元）的合同。位于加州霍桑的太空探
索技术公司获得了一份26亿美元的合同，该公司更广为人知的名字是SpaceX。
“我们希望在美国本土上用美国航天器运送宇航员，不再处于只能依靠俄罗斯的境地，
今天我们向这个目标迈近了一步，”NASA负责人小查尔斯·博尔登(Charles F. Bolden

点被宣告入轨成功，该项火星任务预算为45亿卢比折合为美元是7千4百万，只有美国同
类项目的十分之一，印度总理莫迪称之为“几乎不可能”，这笔钱还不够拍一部好莱坞
的《地心引力》（Gravity）电影。印度的诀窍是什么呢？有三点：
1，人员费用低，众所周知，在世界所有的空间项目中科学家和工程师的薪酬是最大的
预算成本构成。
2，尽量用国产元件，印度这次火星项目所有元件都本着本国产品优先采用的原则。
3，保持有效载荷最小，印度的火星探测器只有15公斤，当然这也对它的性能造成了限
制，不过印度很精明的将目标定位在最重要的方面即火星大气层甲烷气体探测上，这是
当前最令人瞩目的火星探测领域，甲烷气体的形成据信与行星生命有着重要联系。
由于这次成功，印度国内的“应该将钱花在卫生福利上面的舆论消失了”，太空任务
是对国家发展有不可估量推动力的引擎，英国在近年不断加大太空科技开发投入，并将
卫星技术其视为能够再平衡和促进英国经济发展的最重要的8个技术发动机之一。 " |

to get a satellite in a higher orbit, for example – then a barge landing
might be preferable to a ground landing. For this particular launch, a
