Jezero Crater, Landing Site for the Mars Perseverance Rover

This image of Jezero Crater, the landing site for the Mars Perseverance Rover, was taken by instruments on NASA's Mars Reconnaissance Orbiter, which regularly takes images of potential landing sites for future missions. NASA chose Jezero crater as the landing site for the Perseverance rover because scientists believe the area was once flooded with water and was home to an ancient river delta.

Jezero crater tells a story of the on-again, off-again nature of the wet past of Mars. More than 3.5 billion years ago, river channels spilled over the crater wall and created a lake. Scientists see evidence that water carried clay minerals from the surrounding area into the crater lake. Conceivably, microbial life could have lived in Jezero during one or more of these wet times. If so, signs of their remains might be found in lakebed or shoreline sediments.

Jezero 隕石坑講述了火星潮濕過去時斷時續的故事。 超過 35 億年前，河道溢出火山口壁并形成了一個湖泊。 科學家們看到了水将粘土礦物從周邊地區帶入火山口湖的證據。 可以想象，微生物生命可能在這些潮濕時期的一個或多個時期生活在 Jezero。 如果是這樣，他們的遺體迹象可能會在湖床或海岸線沉積物中找到。
