Jezero is a crater on Mars located at 18.855°N 77.519°E[1] in the Syrtis Major quadrangle. Scientists and engineers behind NASA’s rover working on where it landing in Syrtis Major quadrangle on the Red Planet.
Nasa Reveals today that they choose a 49.0 km diameter crater as a landing spot for Mars 2020, Jezero as it was named estimated to have once been flooded with water
In 2020, NASA will land the #Mars2020 rover in Jezero Crater where it’ll explore the location’s story of the wet past of Mars. Conceivably, microbial life could have lived here. If so, signs of their remains might be found in lakebed sediments. More info: https://t.co/sfbF3fNlIl pic.twitter.com/dar5IcQNYM

“The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake did not experience times when the water went down. It probably formed when there was a continual surface runoff “wikipedia
