We knew there was water on the Moon, but not why some craters were empty. Finally we have the answer

by

It’s been a while since It is known that there is water on the Moon. However, accessing it is quite complicated. To begin with, so far only water in the form of ice has been detected. But also, it’s not clear what the best places to look are. There are some clues, but exceptions keep appearing that baffle scientists. That’s why, the study recently carried out by scientists at the University of Colorado Boulder It has been very illuminating. Frozen water hidden in the shadows. The missions that have detected ice on the Moon have located it in the depths of the craters of the lunar south pole. Mostly, in something known as cold traps. These are places that are permanently in shadow, so that the very high temperatures that are reached during the day, of more than 120ºCthey cannot evaporate the water. An essential resource for lunar colonization. The detection of water on the Moon was a great milestone at the time, since it would make it easier for lunar colonizers to use water to cover basic needs in the future. They could use it for drinking, but also, for example, it would be possible separate hydrogen from oxygen through hydrolysis and use it as fuel. Let us remember that the formula of water is H2O, two hydrogen atoms and one oxygen atom. It’s not that easy. Some craters containing ice have already been detected, like the Cabeus. We could think that all the craters of the south pole that are found in cold traps, like this one, will serve as water sources. Unfortunately, the task is not so simple. It is known that several craters in this situation do not contain water, so another pattern must be sought to help future lunar colonizers know where to look. A question of orientation. The authors of the study just published relied on two types of data. On the one hand, the surface temperature data provided by the Diviner instrument of NASA’s Lunar Reconnaissance Orbiter (LRO). On the other hand, the results of a series of computer simulations on lunar evolution. Studying all of this together revealed something interesting. That the orientation of the Moon has not always been the same. Its relative inclination with respect to the Earth has changed slightly over billions of years, so that what is in shadow today may not have been in the past. That’s why there are craters in cold traps that don’t have water. The older the better. Something that these scientists have also observed when reviewing previous studies is that the oldest craters at the lunar south pole are more likely to house water. Therefore, the ideal is to look for ancient craters that are located at the south pole and in cold traps. The number of likely places to search is greatly reduced. In fact, there is already a candidate following this premise: the Haworth crater. According to the models, it has been in shadow for 3 billion years. We will have to check it. The authors of this study are already designing an instrument, called Lunar Compact Infrared Imaging System (L-CIRiS), to analyze this and other candidate craters for water ice. NASA plans to deploy it near the lunar South Pole at the end of 2027. It will be a good way to detect the best lunar water sources with an eye on future long-term missions on our satellite. The more the ground is prepared, the better. Image | Xataka | The “hidden” side of the Moon has been a mystery for decades: China already has a chemical map to shed light

This is what the Moon looks like from the ship

by

When we think of a GoPro, like the GoPro Hero and Hero13 Blackto mention a few examples, the first thing that comes to mind is not space, but sports, travel or any scene recorded at ground level. They are cameras designed to accompany us, to record what we experience from very close up. However, that is precisely what changes when we look at Artemis II: what we have seen these days is how that technology, with specific modifications, has made the leap to a ship that has flown over the Moon. And the most interesting thing is not only that it is up there, but that part of those images have been seen live. action cameras in space. GoPro Confirmed that its cameras are part of the Orion spacecraft’s imaging system, developed by NASA to capture images of the mission and support inspection tasks. These units, adapted for the space environment, are installed on solar panels and are added to a set of more than 28 cameras that record different moments of the trip. All of this also falls within the current phase of the mission, with the ship already back after passing through the lunar environment and with NASA beginning to disseminate this material. Where are they and what are they used for?. As we already mentioned, these cameras are not inside, but in the solar panels of Orion. It is not a coincidence: this position allows something very specific, that the ship itself appears in the frame along with the environment that surrounds it. From there they can capture high-resolution images of the vehicle, the Earth and the Moon during different phases of the journey. The manufacturer details that there are four units modified and integrated into NASA’s imaging system, and in addition to generating this visual material, they are also used to verify the status of the ship at key moments of the mission. In this image of the Orion spacecraft on Artemis I we can see a solar panel deployed The streaming. The first thing that becomes clear is that we are not facing a conventional broadcast. NASA notes that live views from Orion are part of the coverage, but also warns that signal variations may occur due to distance and communication limitations. Therefore, what we see is a broadcast that does not always maintain the same image: there are cuts, moments in blue when the signal is lost and sections in black when the ship is in darkness. In practice, the broadcast does not always maintain the same continuity, something logical in a mission of this type. Where to see it and what type of live it is. The window to all this is on the official NASA channel, with an active broadcast titled “NASA’s Artemis II Live Views from Orion“. It is a technical signal that remains active depending on the conditions of link with the ship and the priorities of the mission. This implies that we do not always see the same image or with the same continuity, something that responds directly to how a flight of this type is managed. The result is an unconventional live broadcast, closer to a technical signal than to a broadcast designed for television. Something difficult to replicate with words. Not only because of the images themselves, which already have enough weight, but because of what they represent. We are talking about a technology that many of us use in everyday contexts and that, with the necessary adaptations, has ended up being part of a manned mission around the Moon. And not only that, it has also allowed us to take a look at that journey almost live, with all the limitations that it implies.

It’s been more than 50 years since we saw the Moon like this. Artemis II has already left new historical images

by

Looking at the Moon again as we are seeing it now is not something that happens every day. More than half a century after the Apollo era, Artemis II has completed its lunar flyby and it has already left a visual trail that returns us to that type of trip that we believed almost from the past. At this time, with the mission progressing as planned, NASA points out that the Orion ship would have already left the lunar sphere of influence and would have begun its way back. How we knewthere has been no lunar landing, but what we have seen during these hours, those images captured by the crew, places us again in front of the Moon from a manned perspective that we have not seen for decades. From here, the key is what this overflight has left us. During their passage through the lunar environment, the Artemis II crew has photographed the Moon at different phases of the journey, capturing both surface details and broader scenes of the surrounding space. All this material is already being organized and published by NASA in your multimedia repositorywhere you can consult images, videos and other content of the mission. We are not talking about a specific selection, but rather an archive under construction that will grow over time. The Moon as we had never seen it again Among the material that NASA has already begun to disseminate there are especially powerful scenes, with the Moon dominating the frame and the Earth visible in the background in some shots. The image conveys the scale of the trip very clearly.with our planet reduced to a luminous sphere in the face of the massive presence of the satellite. In the photographs published by the agency, this play of distances is well appreciated, but also the contrast with the surroundings, that completely black background that surrounds the scene. This is where the images gain strength, because they not only show two celestial bodies, but also the relationship between them seen from a position that very few humans have reached. If we look closer, what appears is an enormous level of detail. In photographs taken during During the flyover, large craters, ancient lava flows and structures that run across the surface such as cracks and reliefs can be clearly seen.. The Artemis II crew described these formations as they observed them, also pointing out differences in brightness and texture that help to better understand the composition of the terrain. It is not just an aesthetic issue: each of these details provides information about the geological history of the Moon. The craters on the eastern edge of our satellite Our planet, in the crescent phase, passing behind the Moon Dark spots of ancient lava on the Moon There are moments of the flyover that go beyond the still photography and that help understand the complete sequence of what happened. During the passage through the far side of the Moon, the ship was temporarily without communication with the Earth, a planned section in which one of the most unique moments of the trip also occurred: the so-called “Earthset”, when our planet disappears behind the lunar horizon from the perspective of Orion. Later, when communication was resumed, “Earthrise” arrived, the moment in which the Earth appears again on the other side. These events occurred within a very measured sequence of observations which also included an eclipse seen from the ship. The Moon completely eclipsing the Sun Another image of the total solar eclipse captured by the Artemis II mission Astronauts also use glasses to view eclipses, just like we would on Earth! Here we see the astronauts capturing images through the windows of the Orion spacecraft Not everything we’ve seen happens outside the ship. Part of the disseminated material also allows us to look inside Orion and understand how this section of the journey was experienced from the inside. In the images shared by NASA you can see the crew working in a compact space, surrounded by screens, controls and onboard systems. There are no grand gestures, but a constant sense of activity and coordination, with the astronauts documenting what is happening as they continue with the flight plan. Although the ship has already left the lunar environment behind and is moving towards its return, there is a part of the mission that begins now. All the material collected during the flyby, as we say, will be analyzed in the coming days by the scientific teams, which will seek to extract information from the images, audio and data captured by the crew. As explained by NASA, these observations will be reviewed in detail once the data download from Orion is complete. Meanwhile, the agency has already made part of this content available to the public on its multimedia platform, where the images can be consulted in high quality.

This is how well the Artemis astronauts eat on their trip to the Moon

by

During a space mission, Everything that is loaded on the ship must be chosen very well.. The fuel depends a lot on its final weight, so it must be calculated carefully, taking into account every last drop of water. That also includes food. That’s why the crew of Artemis II carry with them a menu that was painstakingly designed weeks before launch. Now, just because precautions must be taken does not mean that astronauts do not eat well. It is important that they eat properly, with a balanced amount of nutrients and, of course, including foods that they like. In fact, to guarantee the latter, the crew itself actively intervenes in the design of the menu. Be careful with the crumbs. Food loaded aboard a spaceship must meet a series of requirements. To begin with, crumbs must be minimized, since they could float around the ship due to microgravity, potentially damaging electronic devices if they enter through its cracks. It is also important that the food is vacuum sealed and, if possible, dehydrated. Thus, food security is guaranteed during the days of the mission. In the case of Orión, it has a water dispenser, so that it can be transferred directly to the sachets in which the dehydrated foods are included just at the moment in which they are going to be consumed. Finally, it is important that they are nutritious foods, according to the requirements at each moment of the mission. Two key points. The water dispenser cannot be used during launch and landing. Therefore, meals eaten around these two key moments must be ready to eat, without the need for hydration. The all-round tortillas. Historically, astronauts have had the option of choosing at least one beloved food to take with them on their missions to space. Therefore, in 1985, Mexican astronaut Rodolfo Neri Vela He asked to bring wheat tortillas, like those used to make fajitas. Later, what began as the culinary whim of a single astronaut became one of the most in-demand foods on space missions, since it does not release crumbs, is very versatile and can be stored safely for many days. Tortillas need accompaniment. Precisely because of this custom of including tortillas on menus, over time accompaniments have been added to make their consumption more pleasant. In the case of Artemis II, for example, They carry five different types of hot sauce on board.and. Hot or cold food. Although all food on board can be eaten cold, astronauts have at their disposal a hand warmer, contained in a type of briefcase, in which they can heat the food if they wish. Again, this would not be possible during landing and launch. In that case you should eat as quickly as possible, without preparations. Each astronaut with their personal tastes. Astronauts help prepare the menu before the mission, trying different options and choosing the ones they like best. In fact, the dishes are distributed so that each person will have their own prepared in the ten days they remain on the ship. A single container contains two to three days of meals for each crew member. That includes breakfast, lunch and dinner. The Artemis II Menu. Some examples of foods on board Artemis II are vegetable quiche, broccoli gratin, nuts, beef brisket or macaroni and cheese, among others. As for drinks, in addition to the water that can be obtained from the dispenser, the astronauts have 43 cups of coffee, to be distributed among the entire crew, during the 10 days of the mission. You can also flavor chocolate, vanilla or strawberry drinks. Each astronaut is assigned two flavored drinks a day. It doesn’t taste the same. Without a doubt, the menu of the Artemis II astronauts seems most pleasant. Unfortunately, they will not taste it the same as they did during the tests on Earth, because It is proven that food in space tastes different. Still, I’m sure they enjoy it. As Christina Koch explained in a video for NASAeating those highly packaged foods, together with other people, in such a different place, is a kind of camping picnic with friends.

Artemis II takes off successfully and humanity returns to the Moon after more than 50 years

by

Artemis II It has taken off successfully and we are not facing just any launch. What we have seen marks the return of beings humans heading to the Moon more than half a century after the last missions of the Apollo program, a milestone that for decades seemed reserved for the history books. This time, furthermore, it is not just about returning, but about taking a crew further from Earth than any human being has gone in more than half a century, in a mission designed to validate NASA’s deep exploration system in real conditions. To understand the dimension of this takeoff, it is worth stopping for a moment at what exactly Artemis II is. The mission represents the first crewed flight of NASA’s new exploration system, which combines the Orion spacecraft, the SLS rocket and the Kennedy Space Center’s ground systems. For approximately ten days, the astronauts will evaluate the behavior of the ship in real deep space conditions, something that until now had only been tested without people on board. NASA itself raises it as an essential step to pave the way for future missions designed to return to the lunar surface. The journey that returns humans to the lunar environment Before reaching this moment, what we have had has been a countdown with some tension. In the hours before, the teams had to review an anomaly in a temperature sensor of a battery of the abort system, which NASA attributed to an instrumentation problem and which, according to the agency, would not affect the launch. Added to this was another incident in the flight termination system, the safety mechanism that allows the rocket to be destroyed if it deviates from its trajectory and poses a threat, a problem that placed the mission in “no go.” Both setbacks were left behind before takeoff and are now part of the background of a day that finally went ahead. The planned flight path of Artemis II Over the next few days, what we will see will be a relatively short, but very demanding mission. After launch, the spacecraft will first enter a high orbit around the Earth for about 24 hours to check that all systems are working correctly, before beginning the journey to the Moon. From there, the crew will perform various maneuvers, including a manual control test and approach to the upper stage of the SLS, to validate Orion’s behavior in real situations. The plan is to circle the Moon and return without setting foot on our satelliteon a journey of about ten days designed to rehearse each key phase of the trip. The crew of Artemis II If you look at the crew, What we find is a very measured mix of experience and symbolism. Reid Wiseman is the mission commander, accompanied by Victor Glover as pilot and Christina Koch and Jeremy Hansen as mission specialists, four profiles who have already experienced space first-hand. Together they have accumulated 660 days in orbit and 12 spacewalks, which fits with a mission in which every decision counts. Added to that is something that also weighs: Koch will be the first woman to travel to the Moon and Hansen the first non-American to do so, opening a new stage in who is part of these trips. There is a detail that touches us a little more closely and that we should not lose sight of. Part of this mission also passes through Spainspecifically by Tres Cantos, in Madrid, where Airbus Crisa has designed, manufactured and validated the Thermal Control Unit of the European Service Moduleintegrated into Orion. This system is responsible for supplying air and water to the crew and maintaining the temperature within appropriate levels for both the astronauts and the equipment. It is a discreet piece within the whole, but without it it would not be possible to sustain a mission like this in safe conditions. In development.

The pink Moon is here and again there are fake photos everywhere

by

Like every April, this week the pink Moon will shine in the sky, one of the moons with the best press of the entire year. These days, the media is filled with news crowned with photos in which we see a beautiful pink moon. The problem is that if we go out to look at the sky we will not be able to find it; since, basically, it does not exist. The confusion. With exceptions, every month has only one full moon. Astronomically speaking, these have no name. However, Sometimes they do receive names from popular culture. In fact, there are many full moons that are named after Native American tradition. They gave names to the moons taking into account natural phenomena that took place in that month. In the case of the Pink Moon, it coincides with the flowering of pink phlox. The fields were dyed pink, hence the name. This year the Moon began to be seen on the night of March 31 and will remain in the sky until April 2. Afterwards, it will begin to decrease. Either way, don’t expect any color change. nothing special. There are some moons named after colors that do have something special from an astronomical point of view. For example, blue moons They refer to the second full moon of the few months that exceptionally have two moons in this phase. It is something that normally happens every 2.4 years, although there are exceptions. For example, In 2018 there were two blue moons in one year just two months apart. Moons that are colored. It is normal to see the Moon in its characteristic grayish-pearlish color. However, sometimes, depending on how the light is dispersed around it, we can see it with yellow or orange tones. This depends a lot on the time of year. For example, the full moon closest to the autumnal equinox In the northern hemisphere it can appear more orange because it rises at a narrower angle to the horizon. The amount of particles suspended in the air also influences. And, of course, if a lunar eclipse occurs, we can see the moon in a more reddish tone. The famous blood moon. Other named moons. The Pink Moon itself has many more names, depending on the culture that names it. For example, the Celts knew it as the Moon of New Buds, also because of its relationship with the beginning of spring. On the other hand, in Anglo-Saxon culture it is known as the Egg Moon, because it happens at Easter time, when everything is decorated with the famous colored eggs. In short, there are many names for the same Moon, whose color may depend a little on the place from which you look at it, but always without leaving the usual tones.

Artemis II will make the Apollo that took us to the Moon look like a space slum: it will even have a private toilet

by

If all goes well, Artemis II It could be launched on April 1 towards the Moon. It will be the first time that a manned spacecraft travels to our satellite in more than 50 years and, although this time there will be no moon landing, the capsule with 4 astronauts on board will make a lunar flyby, which will be the highlight of a 10-day space trip. A week and a half during which, logically, the crew will have to clean up and relieve themselves. But how do you go to the bathroom in space? Luckily, the capsule will have a comfort that they didn’t have in the Apollo program. A toilet. The complicated mission of going to the bathroom. From Apollo 10, in 1969, until Apollo 17, in 1972there were a total of 12 astronauts who traveled to the Moon. At that time, her only toiletries were a few wet wipes. to urinate They used devices similar to condoms that were changed daily. When it was time to evacuate, they were connected to a bag, with a kind of hose. It was not a very efficient system and there were often leaks. There was also no system adapted to the female anatomy, since all the astronauts were men. The greater waters. As for feces, a bag was used that stuck to the buttocks. Something quite similar to a diaper, but with a compartment to put your hands in and use toilet paper. Again, there could be leaks. In fact, there is a transcript of an astronaut from Apollo 10 in which he asked for a napkin to pick up a fragment of feces that was floating in the air. Once caught (sometimes literally), the bags were saved and stored for analysis on land. Added to all this is that the astronauts did not have the slightest privacy to go to the bathroom in space. The experience, and especially the smell, could not have been pleasant at all. The urine collection system of the Apollo missions was very rudimentary. Opportunity cost. Whether it is for personal hygiene or for urinating or defecating, going to the bathroom in space involves two major complications. On the one hand, microgravity prevents what should fall under its own weight from doing so. We return to the problem of floating feces from Apollo 10. On the other hand, water is needed. Transporting sufficient quantities of water into space would place excess load on spacecraft. Furthermore, precisely because of microgravity, it would move freely, so that some of the many devices that exist in the small space of a capsule like the Orion of Artemis II could get wet and damaged. For this reason, the use of water is reduced to a minimum and methods are sought to overcome microgravity as much as possible. Artemis II’s toilet. In Artemis II the astronauts They will use liquid soap and leave-in shampooas well as very small amounts of water that can be dried immediately with towels. As for the most difficult part, the Orion capsule has a system similar to that used in the International Space Station. It is a container with a hose connected to a funnel through which urine descends thanks to an air suction system. Each astronaut will have their own hose and, since the crew has three men and one woman, it will adapt to both male and female anatomy, as necessary. Where does all that go?. Once the urine is collected, it is released into space. Regarding feces, they are also collected by suction and stored in sealed bags that will travel to Earth on the return trip. Best of all, this system is isolated, so astronauts can relieve themselves alone. There is a curtain that can be removed if they need more space and a door in the floor of the capsule that allows them the privacy they craved on the Apollo missions.

NASA already has a new date for its manned mission around the Moon

by

Since Apollo 17, no human being has traveled to lunar orbit again. More than five decades have passed since that last manned flight to the satellite, and the return has not been exactly quick or easy. He Artemis program accumulates delays, technical reviews and calendar adjustments, and the Artemis II has also had to stop recently due to a problem detected in the rocket’s helium system. Even so, there is an important novelty: after completing the repairs,NASA has already pointed out a first launch opportunity for this mission that will once again take astronauts to the Moon’s environment. The Date. Following a flight readiness review, the US space agency announced that it is working with April 1, 2026 as the first opportunity to launch Artemis II. That initial attempt is scheduled for 6:24 p.m. (Eastern time in the United States), which in mainland Spain is equivalent to 12:24 a.m. on April 2. This schedule comes after repairing a problem in the rocket’s helium system, an element that regulates the pressure of the fuel tanks and which forced the vehicle to be removed from the platform to replace a defective seal. Artemis II launch window schedule for April 2026 How launch windows work. In space exploration we do not work with rigid dates, but with periods of opportunity. A launch window is the interval in which the rocket can take off to follow the planned trajectory and meet the mission objectives. That margin depends on very precise orbital calculations that take into account the position of the Earth, the destination and the energy necessary to complete the trip. If the vehicle cannot take off within that interval, the attempt is canceled and you must wait for the next available window. Guaranteed launch? Although there is a calendar with concrete opportunities, each attempt still depends on several factors that must be aligned at the last moment. Technical teams continue to work in both the assembly building and the Kennedy Space Center launch infrastructure, and the rocket itself must return to the pad before beginning the final sequence. During a press appearance, Lori Glaze, acting associate administrator of the Exploration Systems Mission Directorate, remembered that there is still work to be completed and that the launch will depend on what the hardware itself indicates. Added to all this is the time, because in a mission like this you cannot operate with the risk of lightning, precipitation, hail or excessive winds. Ground travel. The Space Launch System rocket must first return to the Kennedy Space Center pad from the assembly building. Once there, teams must prepare the vehicle and facilities for the takeoff attempt within the available window. This type of operation requires continuous reviews and coordination between different systems, so it is not always possible to attempt a launch the next day. In fact, Lori Glaze noted that, within the first six days of April, the agency anticipates around four real attempt opportunities. The return. When it finally takes off, Artemis II will mark the return of a human crew to the Moon’s environment for the first time since 1972. The mission will take on board American astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Jeremy Hansen, on a flight of about ten days around the satellite. The plan is for the Orion spacecraft to circle the far side of the Moon, the region we never see from Earth, before beginning the return journey. This flight will serve to check the operation of the systems in real conditions before the next steps of the Artemis program, which aims to take astronauts back to the lunar surface on subsequent missions.

that is on the hidden side of the Moon

Just as it happens when you want to see a shower of stars or meteorites, to observe the universe well you have to flee from civilization. If you are looking for an elevated place, all the better. That explains why there are large observatories in the Atacama desert in Chile, in the Roque de los Muchachos from La Palma or the Square Kilometer Array in Australia and South Africa: deserts, volcanic peaks or remote plains are ideal candidates. That on Earth. Astronomer Jack Burns, whose career began in the late 1970s in the Very Large Array of New Mexicohas spent his entire professional life defending that the next big jump is the Moon. Time is proving him right. The Earth is not enough. Clear skies, a dry atmosphere (humidity distorts signals), and getting away from humanity’s electromagnetic noise are essential to having a good observatory. But as Burns has seen firsthand, even in an environment as privileged as that of the VLA, there are insurmountable limits to knowing more about the origin of the universe for two reasons: Earth’s ionosphere blocks much of that low-frequency spectrum. There is still electromagnetic pollution from humanity, for example electrical, telecommunications, radar infrastructures… that mask the signal. The problem of signs of the beginning of the universe. The most abundant element in the universe is neutral hydrogen, but while in the laboratory it emits at 21 centimeters of wavelength, if the signal arrives from the dark ages traveling through the universe, it reaches the Earth stretched to a range that cannot be heard well. From Earth. These radio signals from the cosmic dark ages, a period of between 200 and 400 million years that It started “only” 380,000 years after the Big Bangare really weak and reach frequencies below 50 MHz (very low), so it is difficult to capture them from Earth. Hajor. Wikimedia CC BY-SA 3.0 The solution is on the far side of the moon. The far side of the moon is probably one of the quietest places in the inner Solar system as the mass of the satellite serves as a kind of natural shield that blocks terrestrial and solar signals. When it’s night on the moon (a night that can last up to 14 Earth days), it is possible to achieve almost complete electromagnetic silence: without direct solar radiation and without interference from the Earth. Ideal for listening to the cosmos. Why is it important. Hearing about the dark cosmic age sounds abstract, but being able to observe them would be useful to better specify the models that explain how the first stars and galaxies were formed, not to mention the advances it would allow in the observation of dark matter, dark energy or gravitational waves. In addition, it opens the doors for the moon to become a permanent scientific platform for humanity. This is the LuSEE-Night radio telescope. It’s time for presentations: Lunar Surface Electromagnetics Experiment – Night It is the radio telescope designed to take advantage of that silence. It operates in a range from 0.1 to 50 MHz with the goal of mapping the first low-frequency sky and potentially capturing those first signs of the dark ages. Technically, it had to overcome contradictory demands: it was required to have high sensitivity to detect the weakest signals and, at the same time, high resistance to deal with a hostile lunar environment with large thermal variations. This minimizes its own noise so as not to dirty the listening and with the ability to communicate with the Earth. A winding path. The program has been full of disappointments: in 2024, the first American lunar landing in 50 years, the Odysseus module, landed poorly and broke a leg. It only had time to transmit two hours of data, enough time to at least confirm that the hardware was working. In March 2025, Firefly’s Blue Ghost 1 achieved the first successful private lunar landing and now LuSEE-Night will travel on its successor, Blue Ghost 2, which will land on the far side of the moon without anyone on Earth being able to see it. What comes next. If LuSEE-Night is successful, the roadmap is ambitious: develop FarViewa colossal lunar interferometer on a larger scale that would allow the study of the dark ages with a precision hitherto impossible. The project would begin assembly in the 2030s and would have initial funding from NASA. In Xataka | The hidden side of the Moon is no longer a mystery.

Mars was the great space battleground between China and the US. Now it’s the Moon (and the stakes are too high)

by

For years, Mars has been the great horizon of space exploration: the inevitable destination to which, sooner rather than later, humanity had to head. Earlier this year, Elon Musk, one of the main drivers of that narrative, assured that The United States could land on the red planet within a period of between five and ten years. In parallel, in China, different voices from its aerospace sector They located the first manned mission Mars around 2033. The message was clear: the race for Mars was already underway. On paper, deadlines are as stimulating as they are challenging. Because sending humans to Mars is not a simple evolution of what has already been achieved, but rather a leap in scale. NASA itself has detailed the enormous technical complexity involved in a mission of this type: from entry, descent and landing systems capable of landing heavy loads in an extremely tenuous atmosphere, to infrastructure that guarantees energy, communications and life support during prolonged stays. Depositing a one-ton rover is not the same as lowering dozens of tons of habitable modules and critical equipment. The race no longer looks at Mars, it looks at the lunar south pole However, while Mars made headlines, the real strategy has been taking another direction. As the NASA Artemis Program and the Chinese Lunar Exploration Program have consolidated calendars, investments and technological milestones, the focus has shifted to a more immediate and pragmatic objective: the Moon. Everything seems to indicate that It’s not about giving up Marsbut to assume that the most sensible path goes through intermediate stages. In both cases, the satellite is emerging as a technological test bed, logistics platform and operational experience before facing a journey of months and millions of kilometers. The new space race, therefore, is not being fought, at least for the moment, at tens of millions of kilometers, but at a few 400,000 kilometers away. This proximity changes the equation: it reduces transit times, facilitates the shipment of supplies and allows us to react to unforeseen events with reasonable margins. But, above all, it opens the door to something that is beginning to take shape: the birth of a lunar economy. Permanent bases, scientific experiments, transportation contracts and infrastructure development could make the Moon not only a destination, but a key node of human expansion in space. The epicenter of this new phase is not just any place, but the environment of the Shackleton craterat the lunar south pole. A permanent darkness, as we can see in the photo that accompanies this article, has fueled the hypothesis that in its shadow areas it could keep water ice. This possibility explains why both the United States and China are targeting this region in their next landings, with the stated objective of studying and, eventually, taking advantage of these resources. In practical terms, we talk about water for consumption, generation of oxygen and production of hydrogen and oxygen as a propellant, whenever technology and economic viability allow it. Illuminated rim and shadowed interior of Shackleton Crater The question, then, is not just what is at the south pole, but what changes if those resources are confirmed as usable. In this scenario, the Moon would cease to be solely a scientific destination and would become a functional piece within space architecture. We are not yet talking about industrial exploitation, but about something more basic: reducing absolute dependence on the Earth in each mission. This nuance introduces a real economic dimension to the lunar race, because it alters the logic of costs, transportation and planning of future operations. This is where the notion of an Earth-Moon supply chain stops sounding futuristic and starts to fit into concrete timetables. Although the lunar economy, with its own supply chainmay seem like a distant concept, its foundations are beginning to be built. On the American side, that architecture is beginning to take shape with very specific missions. Firefly Aerospace launched its Blue Ghost 1 module on January 15integrated into the initiative NASA Commercial Lunar Payload Services. This is a mission that aims to demonstrate what a cargo delivery system would look like for our satellite when it lands on the moon on March 2. In parallel to these cargo missions, Blue Origin is preparing its own movement towards the lunar south pole. The company founded by Jeff Bezos is working on the first demonstration flight of its cargo module Blue Moon Mark 1known as MK1, scheduled for early 2026. The eight-meter-high lander will take off aboard the rocket New Glenn and will need to validate key systems before any more ambitious operations. It should be noted that the mission does not involve resource extraction, but it is a necessary step to operate in the environment where expectations about the ice are concentrated.

If it passes this phase and the final integration with the launcher, the ship could become a relevant asset for future missions to the south pole. Another important fact is that the US agency you have already selected this module for transport the VIPER rover in 2027whose task will be to search for volatiles such as water ice in permanently shadowed regions. On the Chinese side, the centerpiece is the mission Chang’e 7conceived as a more complex deployment than a simple lander. The mission is targeting August aboard a Long March 5 rocket and will include an orbiter, a lander, a rover and a small jump probe. The set aims to operate in the vicinity of the lunar south pole, where experiments aimed at studying the surface and searching for signs of ice in permanently shadowed regions will be concentrated.
