Mars-Rover Curiosity: Sediments probably no testimonies of pastile lakes

The crater gale, which the nasa-rover curiosity has been looking for for nine years on mars, is probably no former lake at all. In any case, that’s a researcher and two researchers of the university of hong kong, who considered the sediments explored by curiosity again exactly. The can therefore even be better explained better through special atmosphere conditions and the influence of wind, a conjunction with water at the formation has therefore not taken place. The humid surroundings, according to early analysis, was once again found there, has never given it. Should the analysis have been confirmed, the a contradiction became unrossed, which has been working for research for years.

Once river water, or not?

Curiosity had landed on the mars at the beginning of august 2012 and has been exploring the crater gale and the hange of the central mountain aeolis mons. Again and again, the researchers working with the instrument have since explained that they have found testimonies of long-lasting lakes and rivers that once passed there. They had existed several hundred million years. At the same time, other investigations had suggested that it has never given the climatic conditions on the red planet, which allows the occurrence of liquid water. Years ago, nasa had noticed that these two research results can not be brought together in accordance with each other.

That’s exactly what the team is about jiageng liu but now managed to explain how the three in the trade magazine science advances. According to various measurement data, they therefore show that some important chemical patterns in the rock can not be explained in the context of a surroundings of lakes. Central point are therefore proven elements that are not waterless and are stronger in the crater at high points, the team will succeed. This indicates processes how to find them in the ground and speak against the theory of water-rich mars. According to their analysis, the sediments have formed in an environment, which is equal to a desert and not in a lakes-rich landscape.

Liu and her team now realize that their findings contradict the galvan theories for the development of the landscape, both the suspected conditions on the ground and the hypotheses to the former atmosphere. That’s why they ame that they will take more research. Nasa had already completed 2017 that the rover provides contradictory research results. Already at that time it had walking that the models of it is a sophisticated river water "really hard" would do. In doing so, the research of liu and her team now returns the hoped-for answer, but promoted a mars of the once river water and thus life-friendly conditions.
