Jezero Crater Regolith Simulant [JEZ-1]

JEZERO

Jezero is a crater on Mars located at 18.38°N 77.58°E in the Syrtis Major quadrangle. The diameter of the crater is about 49.0 km (30.4 mi). Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. 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 inside the crater probably formed during a period in which there was continual surface runoff.

In 2007, following the discovery of its ancient lake, the crater was named for Jezero in Bosnia and Herzegovina, one of several eponymous towns in the country. In several Slavic languages, including Czech, Bosnian, Croatian, Slovakian, Serbian, Montenegrin, and Slovene, the word jezero (pronounced ['je.ze.ro]) means 'lake'.

In November 2018, it was announced that Jezero had been chosen as the landing site for the Perseverance rover of NASA's Mars 2020 mission. In November 2020, evidence of boulder falls was found on the slopes of the delta deposits that the rover is planned to explore, on the wall of Jezero itself as well as on the wall of a small (2-kilometre diameter) crater on the floor of Jezero.
