【兒童報訊】人類一直對火星環境感到好奇,美國太空總署(NASA)早前表示,火星探索車「好奇號」在火星蓋爾隕石坑內發現了富含礦物鹽的沉積物,表明坑內曾有鹽水湖。這次發現證明了火星的環境不斷變化,從溫潤、潮濕的氣候演化成如今冰凍、乾燥的環境。

好奇號
火星探索車「好奇號」在2012年於火星着陸,主要任務是弄清火星環境是否曾適合生命生存,現時仍在火星執行探索任務。

People have been having curiosity about the environment of Mars. Some time earlier, National Aeronautics and Space Administration (NASA) of America expressed that Curiosity rover has discovered sediments rich in salt in Mars’Gale Crater. This indicates that the Crater once contained salt lakes. This discovery proves that the environment of Mars has been ever-changing, from warm and humid climate to dry and cold environment at present.
