3.7 billion years ago it still had lakes

The evidence that Mars once had rivers and seas that covered much of its surface with water continues to accumulate. These tests serve, however, more than just to demonstrate what we already know with some certainty, they also help us to know what these seas were like and, perhaps one day, they will tell us the story of their disappearance. New tests. The images captured by the rover Curiosity have made it possible to identify in the Martian rock some geological structures undulating waves similar to those that can be found in the sandy beds of lakes and on beaches on our planet. These structures not only denote the presence of water, they also imply that it was on the surface, at the mercy of the winds of Mars. The ripples. These geological marks were found in two places and, according to estimates, they were formed about 3.7 billion years ago. This detail is important since, as the team responsible for its discovery emphasizes, it implies that the surface water of the red planet lasted longer than some estimates calculate. That is, they extend the period in which Mars was partially covered by water. The ripples observed by Curiosity are tiny: about six millimeters high, and separated by intervals of between four and five centimeters. From these data, the team estimates that these were formed on the floor of a shallow lake, about two meters deep. Uncovered. Another important detail that these marks reveal to us is that the water in these lakes was liquid on the surface, that is, it was not covered by a layer of ice, since it would be the result of the action of the wind. This also contradicts some of the climate models applied to the Martian climate of the time. “The shape of the waves could only have been formed under water open to the atmosphere and affected by the wind,” stated in a press release Claire Mondro, co-author of the study. Modeling the undulations. The team analyzed the Curiosity observations and simulated through computer models the conditions that gave rise to these marks on the rock. Thus they were able to estimate an average wavelength of about 4.5 centimeters and the estimated depth of the body of water in which they formed. Details of the analysis were published in an article in the magazine Science Advances. Curiosity. He rover Curiosity has been 12 years of activity on the surface of Mars, where it has already traveled tens of kilometers. Perseverance’s older brother arrived in Gale Crater in mid-2012 as the spearhead of the Mars Science Laboratory mission.

Stephen Muldrow, head of the United States Attorney’s Office for the District of Puerto Rico. “The U.S. Attorney’s Office, together with federal, state and local partners, will continue to vigorously enforce federal laws to bring to justice criminals who engage in violent crimes,” Muldrow added. For Christopher A. Robinson, special agent in charge of the Miami Field Division of the ATF (Agency for Alcohol, Tobacco, Firearms and Explosives), the prosecution demonstrates the commitment of that office in the fight against violence and destructive criminal behavior, whether in the United States or the territories.

The woman is scheduled for a hearing this Friday before a judge of the United States District Court for the Eastern District of Missouri. If convicted, the defendant faces a minimum sentence of 5 years in prison. and a maximum of 20 years. The federal authorities thanked the collaboration of prosecutors from the Department of Justice in Mayagüez and the Explosives and Public Security Division of the Puerto Rico Police. Ismael Cartagena, in charge of the Office of Explosives and Public Security, indicated through Facebook this Thursday that, to be effective, “investigations are not carried out in a hurry.” “The responsibility of the law and order agencies is to collect all possible evidence, corroborate information and present it to the public ministry to file charges and achieve a conviction. With this, we make true justice shine,” he said as a reflection on the course of events and the management of the authorities. El Diario is carrying out procedures to interview Cartagena as a follow-up to the coverage of the case. The accusations against the woman occurred about two weeks after the fire that occurred on highway 3301 in the El Combate sector. which affected four businesses: Luichy’s Seaside Hotel, Marinera Restaurant, Bar Marea and Artesanías Juavia. Merchants and residents of the area provided local and federal authorities with audiovisual material that allegedly implicates the woman in the crime.

In an interview with the podcast specialized in issues about Puerto Rico, Válgame PR, this week, Ángel Luis Marrero Negrón, owner of Luichy’s Seaside Hotel, revealed that there are other videoslike one from cameras from a nearby business, which link the woman directly to the events. “That girl is walking with a container, I don’t know, because it was dark, she sprinkles something that is supposedly gasoline and takes a match, and, ‘wow.’ There you can see when the fire starts and she stares, making sure, and walks along the side of the businesses; But, I want to clarify that the coldly calculating woman waited for all the businesses to be closed,” described the interviewee. Audiovisual content began to be shared massively on social networks until reaching members of the Puerto Rican diaspora in the states, who expressed themselves with indignation. St. Louis Councilwoman of Puerto Rican origin, Daniela Velázquez, sent a letter to Bertothy’s employers to take disciplinary action against the woman in light of the seriousness of the allegations. “Your audacity to commit such a brazen act of violence during our beloved holiday season too has impacted Puerto Ricans like me in the diaspora“, Velázquez said to the senior advertising management of HLK Agency. “As a St. Louis-based company with a reputation for commitment to diversity and community impact, I am confident that they will review the situation with the seriousness it requires. “Your response will send a powerful message about living in accordance with global values ​​and communities,” he added.

The case has also encouraged the debate about the humiliating treatment of some tourists towards locals on the island versus the concessions of the authorities to those who visit the territory. The merchants have questioned that, despite the fact that the municipal police were alerted on at least two occasions about the bellicose and aggressive attitude of the woman, who also had verbally and physically attacked staff and customers of Bar Marea before the incident was reported. fire, they did not take her to the barracks or take her information.
