Europe has thought of throwing three robots into a volcanic lava tube and now colonizing the moon or Mars is closer

While the mission Artemis II Its objective is for human beings to return to the moon after more than half a century later, space agencies continue to investigate how to reach other planets and there space robotics is essential because well: space in general and places like Mars are the most inhospitable for life. So a European research group in which, among other entities, the European Space Agency participates, has introduced an autonomous robotic system inside a volcanic lava tube in Lanzarote, like collects this paper published in Science Robotics. Their conclusions bring us closer to a future colonization of the Moon or Mars. The context. Neither Mars nor the Moon have a flat desert surface, but rather they constitute volcanic worlds where there are underground cavities formed millions of years ago by liquid lava. We are not talking about small cavities precisely: there is space for a city to fit in as long as low gravity allows sizes of kilometers, how this study explains. Lava tubes are present on the Moon, on Mars and also on Earth, without going any further we can find some in Hawaii or the Canary Islands, precisely where the research was carried out: The lava tube of La Corona de Lanzarote has sections that reach 30 meters wide and high, come on, that It’s a cave like a cathedral. Why is it important. Because the space environment is harsh: there are extreme temperatures, radiation and meteor showers, a crude combination that makes it difficult for life to exist or simply to establish an eventual foundation for human civilization. On the other hand, if there is any remains of life or frozen water left, these caves are the ideal place to look for it. These structures are strategic because they function as natural shielding against ionizing radiation, extreme thermal flows and meteorites. So the next generation of robots will have the mission of exploring those underground lava tubes on Mars and the Moon to see what their conditions are like. The Lanzarote experiment. Anyone who has been to Lanzarote will know that it has places that seem taken from outer space. That is where the La Corona lava tube is where three different robots with different roles began their characterization mission without GPS or sunlight: The lookout stays outside mapping the entrance. The Explorer: It is essentially a cube full of cameras that you drop into the hole to look before anyone else. The speleologist, who rappels down to enter the darkness at a depth of 235 meters. The discovery. That they did 3D mapping as they progressed was just one of the objectives of this mission, led in the technical section by the German Center for Artificial Intelligence. But what is as important as how: the robots were not controlled with a remote control, but rather functioned autonomously, making their own decisions on the fly. Their performance in collaborative tasks is essential since in space the radio signal takes minutes to arrive from Earth. First Lanzarote, then Mars. The test carried out on heterogeneous and cooperative space robotics was a success, although there is still room for improvement regarding navigation without light and how the sensors respond to interference from the environment.

74,000 years ago, a volcanic eruption led humanity to the edge of extinction. We begin to understand how we survive

74,000 years ago, in a remote lake north of Sumatra, a volcano erupted. But it wasn’t a normal volcano. According to archaeologist Jayde N. Hiniak“The Toba expelled 2,800 cubic kilometers of ash to the stratosphere, created a crater of 1,000 soccer fields” and caused a global winter. That could take our species to the edge of extinction: for more than half a century, many anthropologists are convinced that it was that eruption (one of the greatest known eruptions) that reduced the human population to about 10,000 fertile couples. It would be the most critical moment of Homo Sapiens since it arose. It is true that the theory is controversial and the debate around the real climate change that the Toba created is still very alive; However, no one doubts that what happened that day in Sumatra was a huge catastrophe. And that can be seen in archaeological remains. As Hiniak pointed out“Most archaeological sites show a history of resistance.” In areas such as South Africa or the lowlands of Ethiopia these climatic changes led to the adoption of technological innovations such as the development of arches and arrows. In much closer places (such as Indonesia, India or China), the population also suffered deep changes that allowed him to survive. All this can be known because the Toba left many geological samples distributed throughout the world. Studying the deposits before and after the ash of the volcano gives a lot of information on how these societies changed socio-technologically. The flexibility was key. Regardless of what Toba will cause (or not) drastic reduction Of the population, what is clear is that it allows us to draw conclusions about what was the fundamental feature that explains the survival of human communities: behavioral flexibility.

In Madrid there are 24 tons of Canarian volcanic sand giving tumbos. So they will become a “dry garden”

by

Every summer has its informative soap opera. That is no novelty. What is less common is that, As is happening In La Palma, a few sacks of sand star. It sounds strange, but after all it is the history of the 24 tons of volcanic sand that in May 1,800 kilometers traveled to value the Canarian culture and then ended up abandoned. From the case we already talk to you A few weeks ago. Now we finally know its conclusion, which is no less surprising. Volcanic sand … and traveling. A few months ago, in May, the Canary Authorities had a peculiar idea: they collected more than 20 tons of sand from Tajogaite volcano (La Palma), prepared it and put it in large bags and then uploaded it aboard a ship that transferred it to Cádiz, from where she traveled again on board trucks to Madrid. It took several days to cover the entire journey. Once in the capital they opened the sacks and scattered those blackish grains in the middle of Callao, drawing a huge, dark and bright circle. And all that, for what? To value the Canarian struggle, a popular sport on the islands, but that many do not know in the Peninsula. Coinciding with the Month of the Canary Islands, on May 17 the outdoor playing field was prepared in the Plaza de Callao and everything arranged so that two of the teams with the most footprint in the islands, the Saladar of Jandía and the Candelaria de Mirca, dispute in Madrid one of the most emblematic days of the DISA Government of the Canary Islands. As was in charge of emphasizing The regional government was the first time in the very extensive history of the island sport in which an official fighting day was held in the center of Madrid. But even so, to give it more epic, they decided that the fighters were measured on authentic volcanic land of La Palma. Hence the whole logistics deployment of sacks, permits, ship, trucks and crane. First stop: Callao Square. The experience was a success. In addition to the Arena, in Callao, stands were installed and the appointment attracted a nourished audience that included some authorities, such as the island president, Fernando Clavijo. “Fighting about the sand with which so many palm trees continue to fight to get ahead was a spectacular moment. We were recorded in memory,” Recognize in The Spanish newspaper (EPE) Lorena Hernández, general director of native sports of the regional government. At first, the sand, he remembers, sounded like “crazy”, but the idea went ahead for his “romanticism.” And what do I do with all this sand? That was the next question. Once the competition is over and the experience is over the next question was what to do with those 24 tons (some versions speak of 20) expelled in their day by the Tajogaipe volcano. They could take the way back to the palm. Or they could stay in Madrid as a gift, which was the idea that ended up. There were those who thought that the grains would be divinely in the Madrid volleyball pigs and for that purpose they reserved, but there was a problem: the sand was heated too much, so it was not a good idea to dedicate it to that end. Second stop: Torrelodones. The history of those volcanic sands ended A report With a suggestive headline: “Without a trace of the 24 tons of sand from the palm volcano that Canary Islands gave to Madrid for beach volleyball fields.” The newspaper said that the Consistory had no evidence that they went to dedicate volleyball sand to its volleyball fields. Apparently the material was lost track. The mystery did not last little. A day later the same medium revealed That the sand of discord was actually in a Torrelodones warehouse, where they accumulated dust waiting for the City Council to ultimately accept the sacks formally and look for a new use. Discarded the Volleyball fields and without short -term plans that the Canarian struggle was to take root in Madrid, then it was pointed out to be given a third use: environmental. Third stop: “Dry Garden”. The story seemed to conclude there, but EPE He has just contributed A new fact that (at least apparently) puts the end to the soap opera of volcanic sand, at least for the moment: instead of allocating sports clues, the sand will be dedicated to gardens. And not any kind. There is talk of “dry gardens.” One of the ideas on the table is to create a garden with low water consumption species and a typology similar to those that exist in the Canary Islands. Another option is to use it in other green spaces to take advantage of the properties of the material, of porous structure, good for drainage and that prevents the land from flooding. “It is a high material in minerals, in the Canary Islands it has worked wonderfully. If the sand can have a second use and create a green space with the sand of the palm, it will be wonderful,” Recognize Hernández. Why does it take so long? Simple: bureaucracy. The Cabildo had already prepared a document with the details of the donation, but now it is time to modify it: instead of allocating the sand to sports uses, it will be dedicated to the parks and gardens of Madrid. “Being a donation between public institutions, it requires a lot of paperwork. With this, we believe that we can put an end to management in one or two weeks,” they explain to EPE after specifying that a few days ago new documentation was requested. While the procedures advance in the offices, in the Torrelodones ship follows the one that is probably the most traveling sand in the history of the palm.
