Stop interrupting every two minutes

by

Improve productivity It is one of the biggest concerns of companies. However, a Microsoft study He has revealed that the main ballast for this productivity improvement is the bosses themselves and co -workers who They do not stop interrupting one another. The data suggests that not even those who are remote manage to get rid of that scourge that prevents employees concentrate on your work. 80% of employees acknowledge feeling exhausted because of the amount of interruptions suffered throughout the day. Silent exhaustion in the office. The Labor fatigue Not only is it due to the fulfillment of the working days, but also an invisible but constant phenomenon is added: interruptions. Each notification, message or consultation that is received from a partner is undermining the Capacity for concentrationthat in itself It is not in your best dimensions. The known as “Ping fatigue“Prevents that both the productivity of remote workers and those who are in person in the office can be increased, as they expect 53% of the leaders and managers surveyed for the Work Trend Index 2025 Report of Microsoft, which collects information from 31,000 employees and managers from 30 countries. 275 interruptions per day. According to the data collected by Microsoft, each employee receives an average of 275 interruptions per day at work. Those interruptions that They fight for your attention They include from emails, messages from the corporate messaging platform, meetings or consultations of other colleagues in face -to -face work models. This means that approximately, the workflow is stopped every two minutes to answer a question, address a notification or attend an urgent un programmed meeting. Taking into account that the brain needs between 10 and 20 minutes to re -reach the optimal level of concentration, it makes it impossible for an employee to even pretend to be productive. However. Not advance. The constant interruptions not only affect concentration, but also generate a feeling of chaos and disorganization that does not help to be productive. Employees are forced to change task continuously, which hinders the completion of important projects and increases the feeling of stress and exhaustion caused by multitasking and the constant objective changes. 48% of employees and 52% of managers who have participated in the Microsoft survey claim that their workload is chaotic and fragmented. Meetings do not help. The data reveal that meetings beyond eight In the afternoon, 16% year -on -year have increased, because people participate in different time slots in 30% of them. However, the main chaos generator in organization of the days is that 60% of these meetings are not scheduled and convened improvisedly. Microsoft has detected that improvisation means that, in the 10 minutes prior to those last minute meetings, the use of PowerPoint grew by 122%. That is, employees had to leave what they were doing, to finish the presentations they had to use in the improvised meetings. Microsoft’s solution: convert employees into bosses. Microsoft’s report points out that the arrival of AI agents Specialized will contribute to the reduction of these interruptions since it will be the agent himself who dissipates those doubts that the partner responded before. 82% of the managers of the companies that have responded to Microsoft ensure that digital labor is a priority for them in the next 12 to 18 months. However, and despite the changes that AI promises to contribute to the labor market, there is something against which the agents of AI will not be able to fight: The improvised meetings at the last minute.

Byd, Catl and Huawei fight for the final electric car charger

by

“Load 400 kilometers in five minutes.” That was the phrase that starred in the media. Justly. In fact, in Xataka We also cover the news of the last great novelty of Byd, a recharge for electric cars capable of filling the batteries at the same rate as a hose full of gasoline the deposit of a combustion car. The announcement arrived last March as another sample of to what extent The Chinese electric car is one step ahead. Especially as far as recharge costs and proposals are concerned. Little more than a month later, we have already seen two other proposals that point in the same direction. China ahead in electric cars recharge When Byd presented his ultra -grape loaders, we did not imagine that a war on the technology of the recharge of electric cars in such a short time would be opened. As if they already had their prepared proposal and Byd’s announcement had accelerated the plans for their announcement, Catl and Huawei have had to show their cards. On April 21, the Chinese company Catl He presented his latest innovations in his Tech Day. There they highlighted that they already had a sodium battery (One of the great promises to reduce the electric car) that they hope to produce this year, although in the month of December. They assure that it is an energy accumulator especially resistant to cold, Another problem of this type of technology. And although they put the focus on their batteries for plug -in hybrids with autonomies of 1,500 kilometers adding what was contributed by the battery and the combustion engine, the most interesting thing was the presentation of a battery that can assume the 520 kilometers recharge in five minutes. After the presentation of Byd, From catl They rose the commitment to an energy accumulator capable of supporting 1.3 MWh loads. That is, an amount slightly higher than that presented by Byd, leaving the figure in 2.5 kilometers loaded per second. In addition, Catl not only boasted of a Recharge extremely fastit also made it clear that they were able to sustain this power at a temperature of 10 degrees below zero, from 5% to 80% of the total capacity in just 15 minutes. And they stressed that it is capable of delivering 830 kW of power (more than 1,000 hp) even when electricity is very close to completely running out. Keep in mind that the speed shown in the homologations of an electric car can differ slightly depending on the load with which the battery has. If the battery is low of loading, it usually delivers less power, the recovery or accelerations from slower standing are. These batteries, just like those of Byd, have the problem that to load that power they need a charger that can deliver that stream of energy. To do this, in ByD they say they will deploy their own network of loaders, with 4,000 recharge points capable of delivering up to 1,360 kW of power. To do this, loaders use a liquid cooling system and, to get an idea, they are figures higher than those announced so far to load electric trucks. However, these figures are lower than shown by Huawei during the presentation of its new loaders for electric cars. The Chinese company presented its new plugs, capable of delivering 1.5 MW or 20 kWh of energy at minute. That is, with the right conditions and battery, a car could load 500 kilometers of autonomy in five minutes. Huawei states that he is able to sustain this power for 15 minutes with his new loaders, which makes them especially interesting for electric trucks. In addition, they say they can operate this power between -30ºC and 60ºC and have a dynamic management of the load delivered so as not to saturate the network and balance the power delivered to the maximum possible without knocking down the electrical installation. The biggest problem of this type of loaders is that they need a huge space for installation but, saved this obstacle, except for exceptions such as byd there are no cars capable of supporting this power. Right now, the fastest recharging vehicles do between 250 and 300 kW so there are no cars that benefit from them. And, despite everything, with that power a car with a battery of 100 kWh (of the largest in the market), would be passed from 10 to 80% of the autonomy available in about 14 minutes. With that 70% of recharged autonomy in less than a quarter of an hour, a car of that size would be recovering about 350 real kilometers if it meets a realistic consumption of 20 kWh/100 km. Interesting? There are doubts that such a high load power is interesting from a purely practical point of view. This same idea is what they hold from Mercedeswho ensure that current standards are more than enough but make it clear that they are aware of the importance of offering this warranty To customers. It is not so much a substantial improvement of what is already had as a positive reinforcement to the client. Entering the fight for offering the most advanced loaders in the market is a brand image, demonstrating that you are at the forefront and give the customer a more purchase incentive although, finally, never use it or do it very promptly.

These are the things I did during the blackout so as not to get bored, and what will I do if there is a light cut again

by

Behind him Mass blackout That we suffered a few days ago, I could use the mobile because I had an Internet connection. But there came a time when it didn’t work, so I took the opportunity to perform some activities to avoid boredom until the electricity supply arrived again. I made some, and others will do them in the hypothetical case of having a light cut. Take the opportunity to read at the ereader I’m currently reading ‘THE WAY OF THE KINGS‘, the first novel that begins the Archive of Brandon Sanderson’s storms, but had taken the reading for a week. I took the opportunity to continue reading a few digital chapters, using the Kobo Clara 2E. This model is no longer sold, so if you want a similar one Kobo Clara Color has a price of 169 euros In Mediamarkt. In Amazon it is cheaper, but the shipment takes several months. A EREADER It can come very well for prolonged moments in which we are left without light, since in addition to being able to save many digital books They usually have a several weeks autonomy. * Some price may have changed from the last review Start Berserk Nor did he have too much battery in the ereader, I did not want to exhaust her completely in case the light took too long to return. So taking advantage of the first two volumes from ‘the first two volumesBerserk‘, I decided to start Kentaro Miura manga. The first ‘Berserk’ volume has a price of 16.10 euros In its edition of Maximum Berserk. The truth is that it is a reading that I had pending for a long time, but that I bought, as I commented, a week ago. It is not the most premium edition, but it is very good. * Some price may have changed from the last review Play one Taking advantage that my partner was at home and that in my city it was festive (there was nothing open), we decided to play for a while ONE. We do not have many board or card games, but precisely the Deluxe edition We bought it a while ago and so far we had not played. Deluxe Cuesta edition 17.95 eurosbut the basic edition is cheaper, since it is found by 9.97 euros. * Some price may have changed from the last review Play the Nintendo Switch Although I have been playing some time without playing Nintendo SwitchI have connected it to the dock, so when the light left, the battery had completely charged. I took the opportunity to play just over half an hour at ‘The Talos Principle‘. However, the Nintendo console can be a good source of entertainment, at least for a few hours. Nintendo Switch currently has a price of 275 euros. In addition, he had several Video games in cooperative Local that are compatible with the Joy-with individual (although I also have a separate command), so, despite not getting to play them, we had in mind that we could spend some time playing the games. Nintendo Switch (standard) * Some price may have changed from the last review A puzzle To take advantage, above all, the sunny hours, I will bring the puzzles that I left for a long time at my parents’ house. I always let time pass and in the end I never start to ride them, so in this type of situation it may be well to take that step. Although it is not especially cheap, this Puzzle of ‘The Lord of the Rings’ I find it interesting to buy it. It has 2,000 pieces, so it can take a good time (or days) finish it. Can be found in Amazon by 32.69 euros.

This map shows how the land will be within 250 million years. If fulfilled, Spain will be very lucky

by

About 200 million years ago, the last supercontinent began to fragment. THE PANGEA DIVISION He gave way, very little by little, to the current geological composition. But that which separated will join again. The continents continue to movecolliding with each other, and a theory points out that it will be in 250 million years when another supercontinent arises. We have baptized it as PANGEA Ultimaand the truth is that it will give exactly the same what countries we have as neighbors. PANGEA Ultima. Plate tectonics It is curious because they continue to move under each other, and that is what has led to the theory of Continental derives. These movements are studied to understand the past, as well as to decipher the future, and one of those scholars is Christopher Scotese. This American geographer is the creator of the Paleomap Projectwhich seeks to show not only how the elements have moved these last 1,000 million years, but the prediction of that supercontinent future. And Scote elaborated This map: Who is the one who has inspired The one that opens this article: Curious neighbors. According to this, within 50 million years North America would have turned so much that Alaska would be in a subtropical latitude and Eurasia would also turn, but in the opposite direction, making Great Britain be closer to the North Pole. Africa will get closer to Europe and Arabia, disappearing both the Red and Mediterranean Sea and, within 100 million years, the Atlantic will start diminishing. It will be 150 million years when the Atlantic disappears as a result of being sucked by the American continent, bringing much more America and that block composed of Eurasia and Africa. And the culmination will occur within 200 million years how much that new supercontinent is formed, with the Indian as central sea and a curious neighborhood mixture. According to this model, Latin America would be more or less the same, but with African neighbors in the east. Cuba would be stuck to the United States, Greenland would be next to Canada (bad luck, Trump) and Spain would continue to bordered France and Portugal, but also with Italy, Morocco, Tunisia and Algeria. England would also have stuck to France and Korea would be in a curious sandwich between Japan and China. It will give exactly the same. But the truth is that it doesn’t matter what your new neighbors seem, not because, obviously, you will not be there to suffer them, but because it is possible that humanity has become extinguished by then. Not because we sometimes strive in it, but because conditions will not be the most suitable for the life of mammals. In a study Published in Nature, the researchers predicted that 92% of the land would be Inhabitable for mammals. The reason is that, in a simulation of the climate of this new supercontinent, it is estimated that the temperatures of much of Pangea Ultima will be more than 40ºC, but also the amounts of CO₂ will make the life of the mammals … complicated. Due to the number of shocks between plaques, there will be a great volcanic activity that will increase the CO₂ EMISSIONS TO THE ATMOSPHERA, heating not only the planet, but promoting that the levels of that co₂ bend to the current ones. In addition, the Sun will be 2.5% luminous at that time because its nuclear fusion rhythm will have increased and is something that will contribute to the planet, in addition, to be drier. Spain or so bad. It is not a panorama too encouraging, the truth, since plant life will also experience a massive extinction, but researchers point out that conditions may not be so bad in all parts of the New World. Thus, those closest to the upper part of the North Pole, could have cooler conditions that will facilitate a better adaptation to life. And Spain, Portugal, Morocco or England are in that stage. There is also the possibility that we become specialists in desert environments, becoming night animals in something similar to what is seen in ‘Dune‘. Alexander Farnsworth, one of the researchers who have simulated the climatic conditions of that future, also analyzed From the most serious point of view how life makes its way in Arrakis’s climate and points to that parallelism with the land within 250 million years. One more. Is it this how the land of within 250 million years will be seen? Namely, but there are several hypotheses formulated these last decades that, in one way or another, point to the existence of that supercontinent. One is Novopangeawhere the Pacific will close. Another is Auricawith the closure of both Atlantic and the Pacific. And another model is Amasiawith the union between Asia and America. And the model does not care, they are still similar to the Last Pangea And, after that new supercontinent, the estimate is that the Atlantic will open again, separating the countries and starting a new cycle of rupture. What will happen to life? Well, it will make its way, as the great Jeff Goldblum already said in ‘Jurassic Park‘, because mass extinctions … There have been several.

The lunar map of Johannes Hevelius, the first satellite cartography published in 1647

by

More and more countries achieve what until not too many decades seemed impossible: placing a satellite in The moon. To the difficult mission of sending a probe to hundreds of thousands of kilometers away we can add the double challenge of doing it in your hidden face, unlocked by China Some years ago. One side of the moon in permanent state of escapism to the naked eye. Unlike the hidden face, the one that we can always observe from our homes has been a reason for study and analysis for endless astronomers from several centuries ago. And in such special ephemeris it is worth remembering the first time in which human knowledge drew the known surface of the moon. A Polish did it from the roof of his house, and it took five years to complete the feat. We talked about Johannes Hevelius, Latinized form of Jan Heweliusz. Born in the current Gdańsk, once Danzig, Hevelius would publish in 1647 the first great Atlas of the Moon. Literally. His Selenographia, Sive Lunae Descriptionone of the most celebrated scientific books of the seventeenth century, compiled a good handful of detailed maps that disseminated among popular culture what other scientists and astronomers They suspected long ago. Color version Heweliusz undertook his work, in part, to complete the unfinished and still imperfect designs by Galileo at the beginning of the century. Son of a rich merchant Cervecer, Heweliusz had to attend family businesses first before devoting himself fully to astronomy. It was his unusual social position and his great wealth that allowed him Build telescopes precise and long -range that would install on the contiguous roofs of their homes in Gdańsk. Long night looking at the sky Of methodical procedure, Heweliusz combined in its publication a technical knowledge very high with a Artistic sense More than respectable. Our man inspected the lunar surface every night, Drawing by hand The apprehended reliefs and moving them to a copper plate later. The process of observation, drawing and printing would have almost a five years before being able to finish such a titanic task. With annotations. The result of his work is admirable today. Hevelius’s moon is a hand -drawn moon with great aesthetic sense and, at the same time, enormous astronomical value. On your maps, Heweliusz He proceeded to baptize The topographic characteristics of the satellite from the geographical accidents of the Earth. The Polish interpreted bays, deserts and meanders where there were only craters. Years later, Toponymic work of Giambattista Riccioli and Francesco Maria Grimaldi four years later, in 1615, the baptisms of Hevelius would expire. His maps, however, did survive, and served as a basis for many others elaborated by Other astronomers Europeans in later decades (such as Joanne Zahn in 1696 or Rost in 1723). Of course, the publication had A great tour and caused the usual scandal in the ecclesiastical estate. Hevelius, Polish and therefore Catholic, followed the teachings of another famous compatriot, Copernicus, and believed that the earth Orbitaba Around the sun. Another map included by Hevelius. At that time the representatives of God on earth were not in a position to accept the truth (a patent thing in their recent judgment to Galileo). So when Niccolo Zucchi, an Italian astronomer well related to the Vatican, gave Pope Innocent X a copy of the Selenographia from Hevelius his holiness He replied: “It would be a book without any comparison, of not having been written by a heretic.” Since the Church would lose that game, the Selenographia Heweliusz would mark a before and after in our knowledge of the moon. The astronomer would advance other technical aspects of the telescope and, in addition, observe To other planets of the solar system (such as Jupiter or Saturn) to those who would baptize as “fixed stars.” Despite his privileged vision to the moon, he won the planets cataloging. The astronomer would also leave sketches of his “fixed stars.” Be that as it may, Hevelius’s work marked the imagination of Europeans to the moon during the coming centuries. Already in the 19th century and in the twentieth century the new technical advances would take us from the first high definition images of the lunar surface to the moon landing of 1969. Of course, Hevelius was far from the first occasion in The one we saw The hidden face: it was in 1959 thanks to a satellite Soviet. Today we have closed a circle initiated largely by pioneers like Heweliusz, the astronomer enriched by beer.

We have already seen Yangwang U8 from byd float in a river. It is more impressive than we imagined

by

Cars and water have never got along well. It is enough to go for YouTube to see what happens When a vehicle Try to cross a riverhowever caudalous it is: drowned motors, electrical systems failing and assured breakdowns. However, Byd has been demonstrating that there is an exception for more than a year. Is called Yangwang U8a high-end mastodontic SUV that has just starred in a curious scene in the e-journey organized by the brand in China: floating and moving naturally by a river. Yes, you can navigate. And it’s not just marketing. How can we see in a videothe U8 descends through a slope to the water, floats without difficulty and advances maneuvering gently. It is not something that is seen every day in a serial vehicle. According to Car News Chinathe system allows to navigate up to 3 km/Hy stay afloat for 30 minutes, thanks to an IP67 protection for the car set and IP68 in its key components. Technology at the service of survival. When the driver activates the water crossing mode from the central screen, the car begins to monitor depth, inclination and other parameters by sensors. If it detects adequate conditions, automatically enters emergency flotation mode. At that time, the suspension rises to its maximum level, the windows are closed, the air conditioner goes to air recirculation and the fans adjust its operation to improve the sealing of the vehicle. Even the sunroof automatically opens as an escape in case of emergency. A SUV that wants to step hard in its segment. Yangwang U8 is not limited to floating. It is a luxury SUV that aspires to mark a before and after in its segment. According to the official press note of Bydthe Premium Edition version presented in September 2023 includes technologies such as the E⁴ platform (the first in the world with four independent electric motors in production) and the Disus-P intelligent hydraulic control system. With these technologies, the vehicle is capable of performing maneuvers such as turns on its own axis (Tank Turns), stabilization in case of a puncture and an acceleration of 0 to 100 km/h in just 3.6 seconds. All this with a joint power of 1,200 horses and an autonomy of up to 1,000 km thanks to its plug -in hybrid system. An ambitious bet on the electric. Byd’s proposal goes beyond the engine and traction. Yangwang U8 can completely recharge from 30% to 80% in just 18 minutes with rapid 110 kW charging and offers external food (VTL) capacity of up to 6 kW, enough to feed electronic devices or tools for more than 24 hours. Inside, luxury is also present: Nappa Leather, Curves OLED screens, wood and a 22 -speakers Dynaudio audio system. Everything, topped with the intelligent Nvidia architecture and more than 500 calculation power tops for advanced assisted driving. This is not about adventures. It goes emergency. Although more than one has passed through the head to cross a lake with his car for fun, Byd clarifies that this function is not intended for recreational activities. Its purpose is to provide a useful tool in case of emergencies, such as floods or sudden floods. In fact, if the flotation mode is activated, the manufacturer recommends taking the vehicle to review as soon as possible, as China Car Channel also emphasizes.

Spain suffered a mass blackout. The distributed teleworking came immediately to save many companies

by

Spain has lived an unprecedented fact in its history: A generalized blackout that affected the electricity supply of The entire Iberian Peninsulaincluding Portugal. As a collateral effect due to saturation, the mobile communications network He also collapsed. This made the normal development of The working day. So many companies ended up closing their doors. The blackout that Spain has suffered has been A very extreme casebut teleworking and, above all, distributed work has saved the furniture of those companies that did not have a staff structure based on workers resident in a single citycountry and even continent. While many companies They were forced at closing For not having electricity or Internet access, including those with remote employees, companies with remote workers distributed throughout the world demonstrated their resilience to any local incidence such as the one that left Spain in the dark. We have talked to two of those companies that could maintain their activity in Spain thanks to remote work distributed by different countries. Distributed work and global blackout templates One of the things that the proliferation of the Teleworking after the 2020 pandemicis that talent It no longer has borders And, thanks to technology, someone in Bali I could be teleworking For a Spanish company without any problem. Some digital native companies such as Eventbritea platform for the sale of tickets and events, broke with their centralized organization following the pandemic, and chose to redesign their structure in A decentralized model Based on small teams distributed throughout the world, but mainly in the US, India and Spain. Jaime ValloriVice President of Eventbrite engineering assured that Thanks to that decentralized structureEventbrite continued to function normally while the blackout lasted. “We organize in teams (Squads) that are responsible for the maintenance of the detail pages of certain events. On Monday, the Squads of Spain is not that they could not do the maintenance of those events, they could not even know if something happened because they could not access,” Vallori told us. Before such a scenariothe rest of the teams located outside Spain took over from their teammates. “We activate a protocol so that the teams we have in the United States and India, proactively monitoring those areas that we covered from Spain, but obviously, could not be covered by our team,” said Eventbrite Engineering head in Spain. Vallori stressed that the platform has an incident alert protocol that is automatically climbing to different equipment if it is not answered in a certain period of time. “Since we are geographically distributed, throughout that protocol there is people from different areas of the world Until you get up at all. Therefore, although we had not given us time to activate that checkup (of local events) proactively, in the end through the scaling, it would have reached someone who could access and resolve the incidence, “Vallorí explained. “Our customer service is also distributed between the United States and other countries,” says Vallori. Therefore, if someone with sufficient coverage In Spain I would like to be attended by the company’s customer service could have done so because it remained active despite the fact that the development team in Spain was not operational. Blablacar continued moving in the dark Víctor Méndez, Vice President of Engineering of Blablacar, already told us the Advantages of having a remote template distributed by different countries. Resilience to an event like the blackout that Spain has suffered is one that can add to its list. Florent BannwarthCountry Lead de Blablacar, lived in the first person the disconnection of your entire team of the company’s infrastructure. “He had time to see him come a little and notify France and other countries from which he was going to come to Spain. No one was going to be able to use the platform and we did not know when he was going to re -normalize. So from France they could organize and gave us support, “Bannwarth recalled. In addition to the shared car service, Blablacar also manages an international bus service, so it starts from France’s support was based on replacing the Spanish team in the management of those buses that came out of different parts of Spain. If not for them, This service would have stopped workingjust at the time when neither trains nor airplanes They operated normally. “The service worked without incident and had an important peak of activity, especially between Barcelona and cities in southern France such as Perpignan and Toulouse, many passengers. At the last minute the only thing that worked It was the bus“The head of the Blablacar team in Spain said. On the other hand, Blablacar’s distributed model allowed teams from other countries Maintain the operational platform in Spain so that it would not register incidents once the service was restored, avoiding delays in its implementation as it happened In the railway sector. “The next Tuesday was the day that the most reservations made in Blablacar in more than 15 years in Spain”, due to the need for urgent displacement of those who They had stayed halfway of his destinations because of the blackout. “Another advantage we had was that, part of the user service team that attends in Spanish, works from France and other countries,” although Spain’s staff of Spain was not operational, users who had coverage could solve their incidents normally.

The Steel Tank of the huge Cz-9 rocket has just manufactured

by

Spacex continues years away from any competitor, including the Chinese government. Like the rest of the world, China has been late for reusable rockets and the Starlink satellite constellation, which has an undeniable strategic value. But with Starship, the giant rocket that Spacex is developing in Texas, China is determined to cut distances. The Chinese starship. While Spacex continues to put the highest and most powerful pitcher in the world (not without some difficulty), China has stepped on the accelerator in the development of its own reusable superpesado rocket: the long march 9 (CZ-9) of 114 meters high. The renders are over. This time, the Chinese Academy of Release Vehicle Technology (CALT) has presented two real -scale prototypes of stainless steel tanks of the CZ-9. Its dimensions are not trivial: they measure 5 and 10.6 meters in diameter (Starship has a width of 9 meters). While the 10.6 meter tank fits perfectly with the CZ-9, the purpose of the 5-meter prototype is … less evident. Perhaps CALT is exploring a stainless steel version of the CZ-10, the rocket with which China wants to send astronauts to the moon, or simply using this diameter as a test bench to validate rapid manufacturing technologies (it took only 60 days to design and manufacture the tanks). The SpaceX recipe. While Spacex has the manufacture of stainless steel dominated, for China the production of tanks of this size steel is an advance, since the rockets usually be made of aluminum and carbon fiber. Calt has encountered the challenges of the material: it is more difficult to mechanize than aluminum, and more prone to buckling and deformation in the welds. Overcoming these obstacles has required, according to the state company, “several key technical advances” in assembly, welding and forming. But there are two good reasons why Spacex chose steel: its price (it is cheap and can be manufactured on a large scale) and its resistance (Starship has demonstrated a great capacity to resist the atmospheric braking), a crucial feature for a rocket that aspires to be total and quickly reusable. From partial to totally reusable. China’s plan is first develop a partially reusable version of the CZ-9, scheduled for 2030, and then evolve towards total reuse with version CZ-9BR at some point between 2033 and 2035. Another similarity with Spacex is the number of engines and the chosen fuel: 30 YF-215 methane with 200 tons of thrust each in its first stage, for a total load capacity of 150 tons to the low orbit. So that. The potential uses of CZ-9 They are so varied As in the case of Starship: establish a manned lunar base, display central gigantic solar energy in spaceto launch space telescopes and, yes, manned missions to Mars.
