a mysterious whistle without explanation

In 1969, the Apollo 10 astronauts and one of the Apollo 11 astronauts They heard an intriguing whistle between ghostly and spatial that left them stunned. In both cases, they heard this type of music when they were flying over the Moon. Therefore, it could be expected that the Artemis II crew would have heard it as well. However, we know that he has not. Not only because they have not commented on it, but because today the origin of that sound is known and in the case of this new mission it would have been impossible for them to hear it. Nobody will believe us. It was the month of May 1969 when the Apollo 10 mission, the equivalent of Artemis II if we compare the Apollo program with Artemis, made its particular trip to the Moon. When they were orbiting around the far side of the satellite, the entire crew began to hear a mysterious whistle. The pilot, Gene Cernan, was the first to comment on the matter. “That music even sounds like outer space, right? You hear it? That whistling sound?” Everyone else joined in the comments, which later would appear in NASA transcripts. Later, John W. Young would add: “We’re going to have to find out about this, no one will believe us.” History repeats itself. Contrary to what Young thought, they did believe them. So when the Apollo 11 astronauts embarked on their own journey two months later, they were warned that they might encounter that sound. Two of the astronauts on this mission didn’t hear it, but one did. As the command module pilot, Michael Collins, would later explain in his memoirs, when he was flying over the Moon alone, with his companions perched on the satellite, he heard exactly the same noise. Even though he had been warned about it, he couldn’t help but be overwhelmed. No aliens in sight. In reality, the sound that all these astronauts heard was not alien at all, but something very terrestrial and human: an interference. Apollo 10 didn’t just fly over the Moon. He also tested the empty lander, to check that it undocked correctly from the command module. It did not touch the selenite surface, but it did separate and descend a little. It was at that moment that the sound was heard. In the case of Apollo 11, only Collins heard it at exactly the same moment. When the two parts of the ship were separated. Over time, those in charge of NASA’s transmission system discovered that it was interference between the lander’s radio system and the command module. When they separated, their respective radios they competed between them, causing this curious effect. YoIt is not possible that it was heard in Orion. On the Apollo missions, astronauts could use the command module or the landing module. While the second was on the Moon, the first remained orbiting around it, with only the pilot on board. Instead, Orion consists of a single capsule powered by European Service Module engines. For this reason, during the lunar flyby nothing was separated from the ship and there were no different radio systems that could interfere. Even so, communications systems are no longer what they were. Even if they had separated, a way would have been found to avoid interference. Or maybe not. Yeah your urine freezes and They have to wear t-shirts as blindsperhaps communication would have also given them some problems. The children surpass those parents. Artemis is a younger mission than Apollo, but it has already surpassed it in many aspects. Although the Artemis II astronauts have carried out a mission very similar to that of Apollo 10, they have gone further, breaking his record and, furthermore, they will possibly also surpass them in speed when they enter our planet again. It is a more advanced mission, but without mysterious music or whistles. It’s progress, but also a little more boring.

A strange night a whistle has been listening for weeks in Vigo. They just found the culprit

There are phenomena whose sounds They challenge not only reason, but even the very perception of reality. One of them is remembered in Scotland Since the late 90s, a low frequency buzz that is heard in different enclaves and that in recent times he has returned strongly. In Spain something similar to this part happened in an area of ​​Vigo. Weeks with acute noise when the night that had altered the dream of the neighbors. The problem is that they have just detected the “guilty”, and has a difficult solution. The mystery had wings. It The Faro de Vigo had. For weeks, the neighborhood of Vigo’s journey and Aragón Street has lived in confusion and irritation because of an acute, intermittent and persistent beep that began at nightfall and repeated every two or three seconds until dawn. The initial suspicion fell to multipable guilty: a spoiled alarm after the blackout of April 29, a port of the port amplified by the wind, or even some damaged traffic light out of decibels. The neighbors, unveiled and perplexed, mobilized to find the origin of the annoying sound, called 010, patrolled the streets in search of sound tracks and requested the intervention of the local police. In the end, neither industrial alarms nor port machinery: the author of the beep has turned out to be An unexpected creature and surprising, whose presence had gone unnoticed until then because of its historical silence and its expertise for camouflage. Small and nocturnal. Yes, apparently, the Local Police, after inspecting the area and confirming that it was not any mechanical source, identified the person in charge: a European autillo (Otus Scops), one of the smallest raptors in Europe (does not exceed 20 cm in length or 100 grams of weight) whose song remembers a high frequency electronic whistle. In fact and how I told the middle The biologist of SEO BirdLifeGustavo Ferreiro, the repetitive beep is part of the AVE mating ritual, which is in this time in an incubation phase. In other words: the autillo does not sing to bother, but to communicate its presence, claim territory and maintain the link with your partner during the breeding. Invisibility. Although common in southern Pontevedra, his nightlife and his perfect camouflage among the trees make him an almost inhabitant invisible which can only be detected by your voice. In this caseHabitat’s choice was an urban environment with dense vegetation and old trees, which surround the Matías Park and a nearby abandoned house. European Autillo Survival paradoxes. The case also offers other readings. The paradoxical is that The European Autilloonce a rural bird, it is today forced to take refuge in urban environments due to the loss of biodiversity In the field. Agricultural intensification has eliminated large trees, essential for nesting, and the massive use of pesticides has decimated insect populations that are fed. Thus, the natural habitat has degraded to such an extent that birds seek shelter in urban parks, where they can still find cavities and some food. This forced migration to the city is a reflection of the ecological decline in which the species is found, already included in The “vulnerable” category In the Red Book of the Birds of Spain 2021. Thus, the presence of the Autillo in Vigo is not an isolated anomaly, but rather a symptom of a deep change in the distribution and behavior of many species affected by human pressure on ecosystems. Endangered species. The case of the beep in Vigo demonstrates how a daily discomfort can actually be the life sign of an endangered species. What began as a sleep disturbance became an opportunity to reflect on coexistence between the city and nature. The case reminds others where the presence of cities ends up modifying the life of species. In fact, in Valencia something similar has happened With another copy. EITHER In Icelandwhen the frailecillos season begins and humans hunt them and throw them through the cliffs (by A good reason). In this case, climate change and cities lights threaten the survival of birds. With the autillo, the loss of biodiversity is what is throwing them into such Obern Like cities. That said, and if everything follows its course, the song will send for the neighbors in August, when the chicks and the priorities of the bird change from the courtship to the care.
