【短片】NASA火星探測器 成功發射擬解火星之謎
Nov 18th 2013, 19:00

【國際中心/綜合外電報導】美國國家航空暨太空總署(NASA)的「火星大氣與揮發物演化」(MAVEN)探測器,當地時間18日下午1點28分,從佛州卡納維爾角空軍基地(CCAFS)成功發射,展開找出火星大氣層變稀薄,以及為何逐漸變成無法讓生物生存的原因。

如果探測器發射後也順利運行,預計航行10個月後,於2014年9月進入火星軌道。這次探索不同於NASA過去的任務,不只聚焦於火星乾旱表層,還聚焦於先前從未研究過的上層大氣之謎。了解數十億年前,鄰近地球的這顆行星為何會從佈滿水的狀態,成為幾乎不具任何大氣層的沙漠星球。
