挑戰者號失事30年：悲喜交織的航天夢

1986年，美國NASA的挑戰者號太空梭在任務中爆炸墜毀。17年後，哥倫比亞號在重返大氣層後爆炸解體。儘管如此，美國的太空梭计劃仍有顯著成果，迄今共執行133次任務。

火星上真的有液態水？！

美國宇航局於當地時間28日發布消息稱，在火星上首次發現了存在液態水的證據。這一發現意味著火星上很可能存在生命。

冥王星上新視野

美國宇航局的探測器「新視野號」日前傳回了有史以來最高畫質的冥王星照片。就在兩天前，「新視野號」近距離飛掠冥王星。不過由於距離地球太遠，全部照片傳輸完畢還要等上一年多的時間。

評論：太空沒有仇敵！

美國宇航局希望不再依賴俄羅斯聯盟號宇宙飛船將美國太空人送入太空。德國之聲評論員Judith Hartl認為，這並不出人意料，但烏克蘭的政治衝突令人不安地加快了這一進程。

2014年天文及航天看點展望

在新的一年，不少天文事件和航天活動可以讓太空愛好者大飽眼福。

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.

火星上曾經有過生命嗎？

「好奇」號火星探測器自2012年8月開始發回火星表面的照片。現在首次火星岩石采樣分析顯示：這個星球可能存在生命。

在顯微鏡下，它的形狀看上去像是小馬鈴薯，但是它的存在從來還沒有被人類認識。新發現的能吞噬化學元素砷的細菌讓科學界極為興奮，因為它將改寫生物學家對生命存在於何處的認識。

天外細菌更危險

來自外星球的龐然大物或者微小生物襲擊地球人，這是好萊塢科幻片的一個經典主題。雖然影片「人體入侵者」中的異形蟲是絕對的無中生有，但是宇宙微生物侵犯地球的情形也並非毫無根據。美國國家航空航天局NASA的一項研究表明，地球上的細菌太空遨遊一圈後，會變得更加危險。

專訪：美國NASA局長談未來計劃

看來，人類是不是要征服宇宙已經不算問題了，問題是何時征服。今天，太空旅遊業已經開始起步，載人飛船和國際空間站似乎已經成為流水線作業。但是對天文學家、宇宙學者和航天工程人員來說，未來意味著向空間深處進軍。不久前，德國之聲記者馬耶採訪了美國國家航空航天局局長格瑞芬(Michael Griffin)。
