挑战者号失事30年：悲喜交织的航天梦

1986年，美国NASA的挑战者号航天飞机在任务中爆炸坠毁。17年后，哥伦比亚号在重返大气层后爆炸解体。尽管如此，美国的航天飞机计划仍有显著成果，迄今共执行133次任务。

冥王星上新视野

美国宇航局的探测器“新视野号”日前传回了有史以来最高画质的冥王星照片。就在两天前，“新视野号”近距离飞掠冥王星。不过由于距离地球太远，全部照片传输完毕还要等上一年多的时间。

评论：太空没有仇敌！

美国宇航局希望不再依赖俄罗斯联盟号宇宙飞船将美国宇航员送入太空。德国之声评论员Judith Hartl认为，这并不出人意料，但乌克兰的政治冲突令人不安地加快了这一进程。

2014年天文及航天看点展望

在新的一年，不少天文事件和航天活动可以让太空爱好者大饱眼福。

Kepler-62f, a Small Habitable Zone World The artist's concept depicts Kepler-62f, a super-Earth-size planet in the habitable zone of a star smaller and cooler than the sun, located about 1,200 light-years from Earth in the constellation Lyra. Kepler-62f orbits it's host star every 267 days and is roughly 40 percent larger than Earth in size. The size of Kepler-62f is known, but its mass and composition are not. However, based on previous exoplanet discoveries of similar size that are rocky, scientists are able to determine its mass by association.

The image was taken by Curiosity's Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). APXS can be seen in the middle of the picture. This image let researchers know that the APXS instrument had not become caked with dust during Curiosity's dusty landing. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

在显微镜下，它的形状看上去像是小马铃薯，但是它的存在从来还没有被人类认识。新发现的能吞噬化学元素砷的细菌让科学界极为兴奋，因为它将改写生物学家对生命存在于何处的认识。

天外细菌更危险

来自外星球的庞然大物或者微小生物袭击地球人，这是好莱坞科幻片的一个经典主题。虽然影片“人体入侵者”中的异形虫是绝对的无中生有，但是宇宙微生物侵犯地球的情形也并非毫无根据。美国国家航空航天局NASA的一项研究表明，地球上的细菌太空遨游一圈后，会变得更加危险。

专访：美国NASA局长谈未来计划

看来，人类是不是要征服宇宙已经不算问题了，问题是何时征服。今天，太空旅游业已经开始起步，载人飞船和国际空间站似乎已经成为流水线作业。但是对天文学家、宇宙学者和航天工程人员来说，未来意味着向空间深处进军。不久前，德国之声记者马耶采访了美国国家航空航天局局长格瑞芬(Michael Griffin)。
