happiness after the misfortune
The researchers: Inside looked for deltas. This is the name given to landforms that are created by stones and sediments from feeding rivers. Organic material, such as bacteria, is also often deposited in them. That is why they are in focus in the search for traces of extraterrestrial life. Due to the proximity of deltas, among other things, NASA decided on the rover’s landing site. But after the landing the disappointment followed: Percy, as the scientists affectionately call the rover, was too far away for any concrete research. But now they found clues next to the main delta of the Jezero crater in another branch that “has miraculously been preserved”.
Kodiak shocks scientists: inside
The scientists obtained the new findings by analyzing a nearby rock called Kodiak. It does not belong to the main delta of the former lake, but to a secondary delta. Its position helped identify the strata and debris. Team leader Nicolas Mangold, geologist at the University of Nantes in France, describes the first look at the photos as a shock: “The first picture is actually one on which we can see boulders.” He adds: “A delta fault should not have large boulders. It should be consistent. ”Mangold’s team identified the area as the so-called Gilbert Delta through the rock. These species arise when strong water currents, including waves and tides, shape the landscape. The team believes they know from the find that the river flow increased over time.
