Space reuse seemed like a SpaceX thing. China is already trying to replicate the formula with LandSpace

For decades, access to space was conditioned by a simple and very expensive logic: each launch was an almost unrepeatable operation, with rockets designed to be used only once. That model turned cost per kilo into a structural barrier for the entire industry. Reuse broke that inertia and changed the rules of the game, not as an incremental improvement, but as a different way of thinking about launches. Today, that idea has become the bar for who can compete in the new space economy. The trajectory that is currently taken as a model was not born from a comfortable position. In 2008, SpaceX faced a sequence of technical failures with the Falcon 1 that left the company with no financial margin. Elon Musk even admitted that a fourth explosion would have meant the end of the project. The turning point came first with a successful launch to orbit and, almost three months later, with a NASA contract to transport cargo to the International Space Station. That combination gave oxygen to a company that was still far from demonstrating sustained reliability. When launching is no longer the most expensive. The traditional model assumed that launch was the most expensive and risky part of any orbital mission. NASA analyzes place Historical costs in a typical range of between $10,000 and more than $20,000 per kilo in low orbit, with an average cost around $18,500/kg. The drop in prices associated with reuse altered that balance: with Falcon 9 and Falcon Heavy, the cost per kilo fell into the range of $3,000 to $1,500. By reducing the cost of travel, the door was opened to launch more often and rethink the scale of projects. Why LandSpace is coming into the picture now. In this new scenario of more frequent and scale-oriented launches appears LandSpace. Founded in 2015, a few years after China opened the space sector to private capital, the company has positioned itself as a player focused on building a complete chain from design and manufacturing to launch. Its program aims to recover and reuse the first stage, and in parallel it is committed to liquid oxygen and methane launchers, a combination linked in the industry to cost reduction strategies. This approach fits with China’s need to deploy large satellite constellations in the coming decades. Zhuque-3 from LandSpace With the Zhuque-3LandSpace proposed something unprecedented in China for an orbital-class launcher: attempting to recover the first stage in a real flight. The launch made this vehicle the largest Chinese commercial launcher ever flown and the first by a private company in the country to attempt a vertical landing after completing its primary mission. The profile was carefully planned, with a recovery area built specifically for it in the Gobi Desert. LandSpace has not given figures on the probability of success, and the flight was functioning as a recovery test in real conditions. Zhuque-3 from LandSpace Similar to Falcon 9, with nods to Starship. The comparison with SpaceX is not a rhetorical device, it is in the design itself. Zhuque-3 adopts a very recognizable pattern: nine engines in the first stage, return maneuver, aerodynamic control with grid ends and legs for a vertical landing. At the same time, it is not a carbon copy of the Falcon 9. The rocket is built of stainless steel and uses methane and liquid oxygen as propellants, two features associated with the development of Starship. SpaceX Falcon 9 The December attempt did not end as LandSpace had planned. After takeoff, the Zhuque-3 completed its initial phase of flight, but the first stage failed to execute the final landing maneuver. According to Reutersthe booster had to start its engines about three kilometers from the ground to stop the descent and carry out a controlled landing, something that did not occur. The result was an impact rather than a vertical landing. The design of the test itself assumed that risk: it was a reuse test, not a complete operational mission. Reuse and risk tolerance. The commitment to reusable rockets forces us to review how risk is understood within the Chinese space sector. The aforementioned agency highlights that the local industry has historically been dominated by state companies reluctant to see visible failures. The entry of private companies like LandSpace is introducing another logic, closer to controlled experimentation. The fact that failed attempts are documented and publicly explained suggests that the priority is beginning to shift from immediate success to the accumulation of experience, a necessary condition for reuse to be more than a promise.

Meeting the energy demand of AI is leading to desperate measures. How to reuse old airplane turbines

The AI ​​race has put the electrical infrastructures of half the world in check. Data centers need more and more megawatts, and they need them now. But the energy industry does not play at the same pace, which explains why there are companies installing airplane engines next to these huge graphics card farms. Two options, two problems. When a company builds a new data center for AI, it has two options. The first is to connect to the electrical network, but according to IEEE Spectrumpermits to carry out interconnection can reach eight or even ten years in some regions. AI, however, advances in a matter of months, and cannot wait a decade. Hence, many companies, like Elon Musk’s xAIopt for option 2: build their own power plant on the site. This is not without problems either. Global demand for gas turbines has skyrocketed, and not just because of AI, but because of economic growth in Asia and the Middle East. Manufacturers such as GE Vernova or Siemens Energy have waiting lists of three to five years, and for larger models, the period is longer. As noted in a report by Public Powera new gas plant project commissioned today could begin operating in 2032. Aircraft engines as power plants. This bottleneck has caused, on the one hand, that turbine manufacturers rub their handsand on the other, that companies sharpen their ingenuity. And this is where aeronautical engineering and the reuse of aircraft turbines come into play. The concept of using aircraft engines to generate electricity is not new. They are known as aeroderivative turbines: they are smaller, lighter and easier to maintain than heavy industrial turbines. What is new is the scale and urgency with which this solution is being implemented. From a Boeing 747 to the data center. An American company called ProEnergy has become a protagonist of the trend with a simple plan: buy used jet engine cores, specifically the CF6-80C2 model of the iconic Boeing 747, and adapt them. These engines, after decades of service in the air, are disassembled, reviewed piece by piece and rebuilt for a second life on dry land. The result is the PE6000 unit, a gas turbine that, as detailed the popia companyis capable of generating 48 megawatts (MW) of electricity. A single one of these units can power a small or medium-sized data center, or a city of up to 40,000 homes. A bridging solution. The reality is that these converted aircraft engines are not the definitive solution, but rather what the industry bridges for the first years of operation of its data centers. “Both projects are designed to provide bridge power for five to seven years, which is when they hope to have interconnection to the grid,” says the CEO of ProEnergy. But business is good. The company has already sold 21 of these turbines for two projects, adding more than 1 gigawatt (GW) of capacity thanks to its speed of delivery. Companies can buy a turbine from ProEnergy by 2027 or wait a decade to build a conventional plant. Everyone wins. Except the environment. It is gas that ends up burning in order to have these data centers operational in record time.

The Dana left 800,000 tons of waste and mud in Valencia. Now they will reuse for raw material

The Dana that hit the Valencian Community on October 29, 2024 caused great shock throughout the country, leaving more than 200 fatal victims. In almost five months, I They have generated More than 800,000 tons of waste mixed with mud, a huge figure, since the Valencian Community usually produces an annual average of 180,000 tons. And what are they going to do? In recent months we have seen with much of the national population has turned with the reconstruction and aid in the streets of the Valencian municipalities. However, given the data on the waste, the Ministry of Environment, Infrastructure and Territory He has decided to reuse The land mixed with flood waste for various works in landfills, quarries, agriculture and construction. Reuse. One of the points enabled to carry out this work is in one of the most affected areas of the catastrophe, Catarroja. The project consists of a machine that will make a screening between earth and waste, and then analyze them and make sure they are free of pollutants. Once treated, the Earth can be reused in different spaces. However, it is not there, because it is diversifying in other types of waste, such as tires, butane, scrap and mattresses, for its specific treatment. Reuse in agriculture. The floods caused by the overflow of rivers and ravines dragged large amounts of mud, debris and waste that affected both crops and soil quality. La Ribera Alta and the area of ​​L’Abufera, Key areas for agricultureThey saw how their rice crops, citrus and vegetables were destroyed. For this reason, working on the recovery of the affected soils trying to the sludge and the polluting sediments. However, mud samples taken in the area of ​​the Natural Park of L’Albufera are currently low, but concern persists on long -term effects. Other points to manage waste. The Ministry of Environment, Infrastructure and Territory has created Local collection points in which to accumulate the remains of the municipalities. Transfer points have also been enabled where to make a first crushing treatment, separation of metals and mattresses, located in Quart-Manises, Picasent, Catarroja and Alfafar. Waste energy management. While the Valencian Ministry has promoted this type of solutions, also It is exploring The possibility of incinerating some of this waste. In fact, incineration, as if it were a thermal power plant, allows transforming the heat generated into electricity. In fact, several experts They have defended That incineration reduces the percentage of rejection and, in addition, put as an example that burned waste produces ashes that are useful to develop, among other things, cement. In addition, Spain has advanced Significantly in the use of the biomethane, a clean energy source that can be generated from organic waste and landfills. The use of biomethane could complement the efforts of the Ministry of Environment, Infrastructure and Territory, by providing a sustainable energy solution and reducing the environmental impact of the waste generated by the DANA. Forecasts While the terrain is still being cleaned, one of the areas most affected by waste dragged by the Dana has been the Albufera of Valencia and its beaches. In them, more than 60,000 kilograms of garbage have been removed, including up to 36 varieties of different waste, such as tires, bumpers, butane, furniture and plastics. As cleaning and recovery efforts continue, more additional measures will have to be implemented to address waste dragged by future floods or natural catastrophes.
