NASA picks Jezero Crater delta as landing site for Mars 2020 Rover


Washington: NASA has chosen Jezero Crater delta as the landing site for its upcoming Mars 2020 Rover mission, the US space agency said.

Jezero Crater, 45 kilometres in size, is located on the western edge of Isidis Planitia. It is a giant impact basin just north of the Martian equator where the sediments contain clays and carbonates.

Its ancient lake-delta system offers many promising sampling targets of at least five different kinds of rock, including clays and carbonates that have high potential to preserve signatures of past life.

The landing site in Jezero Crater offers geologically rich terrain, with landforms reaching as far back as 3.6 billion years. This was informed by Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, in a recent statement.

“Getting samples from this unique area will revolutionise how we think about Mars and its ability to harbour life,” Zurbuchen stated.

The crater, once home to an ancient river delta, could have collected and preserved ancient organic molecules and other potential signs of microbial life from the water and sediments that flowed into the crater billions of years ago.

The site contains numerous boulders and rocks to the east, cliffs to the west, and depressions filled with aeolian bedforms.

The Rover mission is scheduled to launch in July 2020 as NASA’s next step in the exploration of the Red Planet.

It will not only seek signs of ancient habitable conditions and past microbial life but will also collect rock and soil samples and store them in a cache on the planet’s surface.

Earlier in November, ExoMars rover— the European Space Agency (ESA) and Russian Roscosmos’ joint venture to the Red Planet that will set out in 2020—also chose a landing site on Mars’ equator called Oxia Planum, which had in the prehistoric era housed a massive pool of water.
