Given That February 18, 2021, Determination has actually been checking out the Jezero crater flooring, consisting of a direct exposure of rock and sand that the rover’s science group calls Séítah (which indicates “among the sand” in the Navajo language).
Among the primary expedition targets within Jezero crater is the unspoiled delta deposit, and a lot of the forecasted landing websites for the rover were clustered extremely near the scarp of this delta. Throughout landing, the rover’s computer system diverted the rover away from the delta to the eastern side of Séítah, which itself was thought about too sandy and rocky for a safe landing.
While the rover’s comprehensive expedition of the Jezero delta will need to wait till later on in the objective, the rover’s landing website has actually offered the group a chance to go into the geology and origin of the crater flooring rock systems.
Throughout the very first couple of months of the objective, Determination checked out a greatly cratered rock system consisting of plentiful polygonal fractures and a structure comparable to a basaltic volcanic rock. In September 2021, Determination got in Séítah and started checking out a brand-new and various geologic system. The rocks in Séítah have an extremely intriguing structure, and are mainly consisted of the mineral olivine. The rocks of Séítah likewise appear really comparable to a geological system that covers almost 20,000 km 2 beyond Jezero crater. Olivine is an igneous mineral, and is generally among the very first minerals to take shape out of a lava. Researchers on the rover group are attempting to comprehend how this olivine-rich rock might have formed.
Among the methods we do this is by determining “terrestrial analogues,” or rocks here in the world that look comparable to what the rover is seeing on
