美國航空航天局對火星的探索,進入新的階段。「毅力號」火星探測器,將在火山口三角洲,收集岩石樣本,尋找火星生命存在的證據。<<https://newsroom.ap.org/detail/NextstageoftheRedPlanetmissionsearchingforsignsoflifeonMars/f40e2e7833b2c2531d84608405bb948f/video?hpSectionId=9ceca01773564ee6b3026511ce4821bf&st=hpsection&mediaType=video&sortBy=arrivaldatetime:desc&dateRange=Anytime&totalCount=3151¤tItemNo=62 圖編請加:NASA >> 去年二月,「毅力號」火星探測器登陸火星,降落在著名的傑澤羅火山口,研究人員相信,在數十億年前,耶澤羅有一個巨大的湖泊,並在其中形成了河流三角洲,而這很可能意味著曾有生命存在。 NASA火星探測器科學家 布里奧妮·霍根:「三角洲是一個非常重要的指標,表明杰澤羅隕石坑曾經有一個湖泊。這真的很令人興奮,因為它告訴我們,事實上,那裡有一個持續的、古老的、可居住的環境,古代微生物生命可以在那裡生活。」 <<2. SOUNDBITE (English) Briony Horgan, Associate Professor of Planetary Science at Purdue University and rover scientist on NASA's Perseverance Mars Rover: "Deltas are a really important indicator that there was once a lake in Jezero Crater. And that's really exciting for telling us that there were it was, in fact, a sustained, ancient, habitable environment where ancient microbial life could have lived. >> 「毅力號」在火星上第一年的任務,主要是對其周圍環境進行了偵察,駕駛一架小型直升機飛越傑澤羅火山口。而現在,它要開始正式探索河流三角洲,並收集岩石樣本。 NASA火星探測器科學家布里奧妮·霍根介紹,「毅力號」將鑽碎岩石,獲得如同鋼筆或鉛筆一樣大小的樣本,將其送回地球。 不過,這個「火星樣本返回」計劃說起來容易,執行起來可要費些功夫。 NASA火星探測器科學家 布里奧妮·霍根:「另一個小型探測器將來獲取樣本,將它們放在一個小型火箭上,該火箭將發射到軌道,與另一顆衛星會合,然後最終將其送回地球。」 <<6. SOUNDBITE (English) Briony Horgan, Associate Professor of Planetary Science at Purdue University and rover scientist on NASA's Perseverance Mars Rover: "...... And that'll happen through another small rover coming out to grab the samples, putting them on a little rocket which will launch into orbit, rendezvous with another satellite, and then eventually return that back to Earth.........">> 專家預測,大約2030年,這些岩石樣本才能抵達地球。 新唐人電視台記者 周琪 綜合報導
