Jezero crater

Subject: Science and Technology

Context: Perseverance landed on depression on Mars called Jezero crater recently.

Concept:

Scientists believe the area was once flooded with water and was home to an ancient river delta.
Conceivably, microbial life could have lived in Jezero during one or more of wet times there. If so, signs of their remains might be found in lakebed or shoreline sediments.
It is 28 miles (45 kilometers) wide, and is located on the western edge of a flat plain called IsidisPlanitia, which lies just north of the Martian equator.
It is oldest terrain to be explored on Mars.
