**美国：俄罗斯能够消除乌克兰人道危机**
俄罗斯敦促联合国立即采取措施，应对乌克兰的人道危机，但美国认为俄罗斯有能力消除这一危机。
星期二，联合国安理会在俄罗斯的要求下举行紧急会议。俄罗斯常驻联合国代表丘尔金说，人道主义原则在乌克兰东部必须得到遵守。他指责基辅政府在该地区实行暴力镇压。
美国常驻联合国副代表迪卡洛说，俄罗斯只要不再为分离分子运送战斗人员、武器和资金，就能完全消除人道危机。迪卡洛指出，俄罗斯不但不这样做，反而把乌克兰边界附近的军力增加了一倍，并计划举行大规模军事演习。
联合国人道机构官员约翰•金对安理会说，由于城市地区发生暴力，乌克兰的人道局势更加恶化。他表示，逃离家园的人们并未登记，因此很难对救援需求做出评估。
**US: Russia Can Stop Humanitarian Crisis in Ukraine**
Russia is urging the United Nations to take immediate action to deal with the humanitarian crisis in Ukraine, but the U.S. says Russia has the means to stop it.
At an emergency Security Council meeting called by Russia Tuesday, Ambassador Vitaly Churkin said international humanitarian principles need to be followed in eastern Ukraine. He criticized the government in Kiyv for what he calls its violent repression of the region.
Deputy U.S. Ambassador Rosemary DiCarlo said Russia can stop all of it by halting the flow of fighters, weapons and money to the separatists. But she said Russia has instead doubled the number of troop battalions near the border and plans large-scale military exercises.
U.N. humanitarian official John Ging told the Council the humanitarian situation is getting worse in Ukraine especially because of violence in urban areas. He said many who have fled their homes do not register with officials, making it hard to assess relief needs.
**一艘欧洲无人飞船将与彗星会合**
星期三，10年来一直在太阳系追踪一颗彗星的空间探测器终于将飞抵具有历史意义的目的地。
欧洲太空署的罗塞塔号无人飞船将与67P/楚留莫夫-格拉希门克彗星交会。经过最后一系列运行后，罗塞塔号无人飞船将进入距离这颗彗星约100公里的轨道。如果运作成功，造价17亿美元的罗塞塔号将成为第一个与彗星会合的空间探测器。
罗塞塔号进入轨道后，将在未来一年中伴随67P彗星，并在这颗彗星飞往太阳途中进行观测。这次使命的最重要时刻将在十一月，届时罗塞塔号将发射一个小型探测器，在67P彗星表面着陆。这将是有史以来的第一次。
**European Satellite to Make Historic Rendezvous with Comet**
A space probe that has been racing across the solar system to catch up with a comet for a decade will finally reach its historic destination Wednesday.
The European Space Agency's Rosetta spacecraft will rendezvous with the Comet 67P/Churymov-Gerasimenko after a final set of maneuvers that will place it in an orbit about 100 kilometers above the comet's surface. If successful, the $1.7 billion Rosetta will become the first spacecraft to rendezvous with a comet.
Once it reaches orbit, Rosetta will escort Comet 67P for the next year and observe it as it heads towards the sun. The highlight of the mission will come in November, when Rosetta will release a small probe that will land on Comet 67P -- the first ever spacecraft to accomplish such a feat.
