Lo Que Vieron los Astronautas de Artemis II Cambia Todo

We have just received the first images from the historic lunar flyby of Artemis II. And what they show is absolutely impressive. After more than 50 years since the Apollo missions, Humanity has once again traveled around the Moon. And this time it's not just about returning, but about preparing ourselves for something much greater. The permanent return of humans to the lunar surface, and perhaps one day the journey to Mars. The Artemis II mission marks a historic moment because it will be the first time since 1972. that astronauts return to venture so far from Earth. Four astronauts are on board. Reed Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. His vessel is the Orion module, designed to withstand the harsh conditions of deep space, very far from the natural protection provided by Earth's atmosphere. During the flyby, the crew reached a distance of approximately 4,000 miles above the lunar surface. and broke the record for the greatest distance humans have ever been from Earth since the Apollo 8 mission in 1968. And here's something incredible to put that distance into perspective. The Moon is about 384,000 kilometers from Earth. That means the astronauts were so far away that our planet began to appear small, fragile, and almost unrecognizable. In some images, Earth appears as a small blue dot hiding behind a crescent moon. Three worlds in a single image: Earth, the Moon, and the emptiness of space between them. It's hard to see something like this without feeling that our planet is truly tiny. The mission also allowed us to observe something extremely rare: a total solar eclipse seen from lunar orbit. From the astronauts' perspective, the Moon completely covered the Sun for approximately 54 minutes. For comparison, on Earth a total solar eclipse typically lasts only a few minutes. But why does it take so much longer from lunar orbit? Because from the crew's perspective, the Moon appeared much larger than how we see it from Earth. which allowed blocking the Sun for much longer. In some of the most striking photographs, the Sun is completely hidden behind the Moon. But the most fascinating thing is that one edge of the Moon is softly illuminated. That glow does not come from the Sun; it comes from the Earth. This is known as Earthshine or Earth's glow, The sunlight reflected by Earth that partially illuminates the lunar surface. It is exactly the same phenomenon we observe here when the dark part of a crescent Moon appears faintly illuminated. But this time, the roles are reversed. From the Moon, the Earth becomes the source of light. And while that eclipse was taking place, the astronauts also managed to capture several planets in the background of space. Saturn, Mars, and Mercury appeared visible near the Moon. All of this was possible because during the eclipse the Moon became much darker. And the cameras were able to use longer exposures, allowing them to capture stars and planets simultaneously. But those lengthy explanations also revealed another important detail. In some photos, small bright spots appear on the dark part of the Moon. They are not stars. His dead pixels in the cameras, likely caused by intense radiation from deep space. Beyond Earth's atmosphere, astronauts are exposed to a much more hazardous environment. The Earth constantly shields us from much of the solar and cosmic radiation, But Orion and his crew are traveling much farther beyond that protection. And that reminds us of something important. Going to the Moon remains extremely difficult. When we think of the Moon, we typically imagine a gray sphere, full of craters and quite uniform. However, the images from Artemis II show that the Moon is far more complex, dramatic, and varied than we usually imagine. During the flyby, the crew captured some of the most detailed views what we have had for decades in certain regions of the lunar surface. One of the most impressive ones was the Eastern Basin. The Oriental Basin is one of the youngest and best-preserved impact craters on the entire Moon. It has hundreds of kilometers in diameter and possesses enormous concentric rings. that formed when a gigantic asteroid struck the lunar surface billions of years ago. and countless other overlapping craters can be seen around it, showing that the Moon has been struck again and again over billions of years. Unlike Earth, the Moon has no atmosphere, rain, oceans, or plate tectonics to erase the marks of the past. Each impact remains there practically forever. That is why looking at the lunar surface is like viewing a fossil record of the early solar system. Another thing that makes these images so impressive It is the way in which sunlight falls upon the lunar surface. Many of the photographs were taken near the so-called terminus line. That name may sound strange, but it simply refers to the line that divides day and night on the Moon. Yes, precisely there where the lunar terrain becomes most spectacular. The mountains cast enormous shadows, the edges of the craters appear much higher, And the cracks and unevenness of the terrain become much more visible. It's similar to when we on Earth see a city at dawn or at dusk. Long shadows make buildings, mountains, and objects appear much more dramatic. The same thing happens on the Moon. That is why some of the craters photographed during Artemis II appear so deep and intimidating. But perhaps one of the most exciting moments of this mission has nothing to do with geology. but with something much more human. The Artemis II crew proposed naming two craters that currently do not have names. One of them was named Integrity, in honor of the Orion module. And the other was named Carol, in honor of Reed Wiseman's late wife and mother of his children. It's a small detail, but profoundly moving. But it would be better if you heard it yourself. This reminds us that, even in a mission as technological and scientific as this, We continue carrying our stories, our memories, and the people we love with us. Even as far as the Moon. Another thing that happened during the Artemis II flyby The crew captured some of the most spectacular images of Earth ever seen from lunar orbit. And one of the most impressive ones was something known as Earthset. It is basically the opposite of a terrestrial sunrise. Instead of seeing the Sun disappearing behind the horizon, The astronauts saw the Earth slowly disappearing behind the edge of the Moon. The dark side of the Earth was passing through the night, while on the illuminated side, enormous cloud systems could be discerned spinning over Australia and Oceania. It is a beautiful image, but also strange. Because we are normally accustomed to looking at the Moon from Earth. But here the opposite occurs. From the Moon, the Earth becomes the distant object that rises and sets on the horizon. And that completely changes our perspective. Well, we are accustomed to seeing the Moon in phases. Full moon, waxing crescent, waning crescent. But from the perspective of the Moon, Earth also goes through phases. It can appear full, waxing, waning, or completely dark. And this makes our planet appear strangely alien. Almost as if it were another world. And that must have felt very different from any other human experience. It's easy to get lost in the beauty of the Artemis II photographs. The Moon, the Earth, eclipses, craters, and the deep space. But behind each of those images is something even more incredible. There are human beings. Each photograph was taken by real people who were living through something that very few human beings have experienced throughout history. Reed Wiseman is the mission commander. Victor Glover will become the first African American astronaut to travel around the Moon. Christina Koch will be the first woman to undertake a lunar mission. And Jeremy Hansen will be the first Canadian to travel to deep space. During the lunar flyby, we saw several photographs of the crew working, observing, and simply enjoying the moment. In some images, they are seen using professional cameras to photograph the Moon. In others, we see them observing through the windows of Orion as the lunar surface slowly passes in front of them. There were even photographs showing them using special glasses to safely observe the solar eclipse. Yes, and even in space you need protection to look directly at the Sun. We also saw a series of highly symbolic photographs in which Christina Koch, Victor Glover, and Jeremy Hansen are shown looking toward Earth from the same window. Meanwhile, Reed Wiseman appears, gazing toward the Moon. It is a simple, yet powerful image. Three people observing the place we come from, and one observing the place we are going to. Although the images from Artemis II already seem historic, the most important thing is that this mission is only the beginning. Because Orion didn't travel to the Moon just to take stunning photographs. The true objective of Artemis is much more ambitious. NASA wants to return astronauts to the lunar surface, establish a permanent presence there, and use the Moon as a kind of training ground for future missions to Mars. And that completely changes the way we see these images. Because we are not just witnessing a mission of exploration. We are witnessing the first steps of something much bigger. Following Artemis II will come Artemis III, the mission that aims to take humans back to the lunar surface for the first time since 1972. And this time there is a huge difference compared to the Apollo missions. It's not just about planting a flag, picking up a few rocks, and going home. The idea is to stay, learn how to survive for weeks or months away from Earth. And that won't be easy. The Moon appears close when we see it in the sky, but in reality, it is an extremely hostile place. There is no air, no liquid water on the surface, and no protection against radiation. But the positive aspect is that the Moon's gravity is much weaker than that of our planet. That makes launching a spacecraft from there much easier than taking off from Earth. That is why many scientists believe a lunar base could become the ideal starting point for missions to Mars. And here is where Artemis truly becomes exciting. Because Mars is much, much farther away than the Moon. Depending on the positions of both planets, a trip to Mars could take between six and nine months. This means that before attempting something so extreme, we need to learn how to live off Earth for extended periods. And the Moon is the perfect place to learn all that. Only time will tell.
