NASA loses contact with its key orbital repeater

When you launch a probe into space that is not exactly cheap, without a doubt one of the biggest fears you can have is that it will stop send data or cut off your communication. This is precisely what has happened 225 million kilometers away with the MAVEN probe who has lost contact like NASA itself has been able to confirm. And this has been carrying out its function outside of our planet for many years now. His story. The ship, which has been orbiting Mars since 2014, it stopped communicating with Earth on December 6, 2025 and, so far, attempts by the Deep Space Network (DSN) to reestablish the connection have been unsuccessful. Although the worrying thing is not only that this scientific instrument could have been lost in space, but that MAVEN is a fundamental piece in the “interplanetary internet” that connects the Rovers on the surface with us. What we know. As NASA itself reports, everything indicated that it was a very normal day at the orbital office. MAVEN was preparing for its usual passage behind Mars that would leave it hidden, but a priori everything was working correctly inside. But logically the moment it is lost behind mars (something that almost always lasts between 25-30 minutes), the signal loses. However, on day 6, when the probe was to leave the shadow of Mars and reestablish the link with the Deep Space Network, the signal never arrived. It stayed just behind Mars with no further signs of ‘life’. Now the objective is to try to wake up the ship without success, although they assure that there are no indications that its trajectory has been altered. The worst possible moment. This is something that hasn’t had the best timingand as is known, we are already approaching the superior solar conjunction that is expected for January 2026. This phenomenon occurs when the Sun comes between the Earth and Mars, which makes communications very difficult and risky. In this way, if NASA does not recover MAVEN in these weeks, everything indicates that they will have to wait several weeks without being able to make more attempts. Because. Among the hypotheses that NASA has right now to explain this failure is radiation. Recently the Sun has been very active and a flare or cosmic ray could have corrupted the probe’s onboard computer, as already happened to other missions as Curiosity. Another hypothesis lies in atmospheric drag, since MAVEN flies really low. Thus, if a solar storm had ‘bloated’ the Martian atmosphere, the friction could have destabilized the spacecraft, forcing it to enter a mode where its antennas were not pointed at Earth. Its importance. This probe is not just a decoration in space, but rather plays a crucial role in understanding how Mars lost its atmosphere and water over the eons. It has been a resounding success, surviving well beyond its original lifespan. But in 2025, its role is more pragmatic: acting as a signal repeater. Right now the Rovers that are on the Martian surface as they are Perseverance and Curiosity They do not have the necessary power to optimally send information to Earth. This caused its data to be passed to MAVEN and other probes and then sent to Earth. In this way, losing MAVEN means leaving two probes that are much older on Mars and that could cause problems when sending this data.

Faced with the threat of an “orbital Pearl Harbor”, Europe has made the same decision as the US: shield space

The race to militarize space has accelerated to an extent unprecedented since the end of the Cold War. The reasons are several, but the main one is driven by the combination of explicit russian threatscovert sabotage and an international architecture incapable of containing the emergence of atomic weapons out of the atmosphere. The last one to join: Europe. The war in orbit. Moscow not only has reactivated its classic nuclear discourse, but has opened a second front in low Earth orbit through the development of anti-satellite systems equipped with nuclear warheads that openly violate the Outer Space Treaty. In this context, European and North American experts match in which the Kremlin is lowering the threshold for the use of tactical nuclear weapons both on Earth like in spacewhile experimenting with platforms capable of camouflaging orbital bombs designed to disable satellites essential for the economy, defense and communication. Thus, the very idea of ​​a “Space Pearl Harbor” (a nuclear explosion that destroyed thousands of satellites, blinded entire continents and turned low orbit into a radioactive dump for generations) has forced Europe to abandon the romantic vision of an exclusively civil space and enter a new strategic reality which combines deterrence, diplomacy and operational preparedness. The bet of the old continent. This turn has crystallized in a historic decision: For the first time, European Space Agency countries have approved funding a program designed explicitly for military functions. He ERS projectconceived as a “system of systems” equipped with surveillance capabilities, secure navigation, encrypted communications and Earth observation, marks Europe’s entry into the club of actors who recognize that their future security depends both on what happens on the ground and what happens hundreds of kilometers above it. The approved financing (1.2 billion euros with more to come) comes accompanied by an unprecedented political mandate that redefines the concept of “peaceful purposes” at a time when China multiplies its space capabilities and Russia turns orbit into a space hybrid pressure. The magnitude of the support, bordering 100% of what was requestedreflects an internal consensus: without its own capabilities, Europe would be a vulnerable spectator in a conflict that would be decided by the speed and resilience of its satellite constellations. The French and German response. On this new board, France and Germany have assumed a central role both for its industrial capacity and for its newly adopted conviction that the wars of the future will begin (or be decided) in space. Paris has invested 10 billion euros in its new Space Command, oriented to military operations in orbit, to shield satellites against kinetic attacks and to promote an interoperable architecture with NATO. Berlin, for its part, has announced an investment of 35 billion until 2030 to reinforce its own Space Command, develop guardian satellites and equip itself with advanced early warning systems. Both countries have publicly assumed that orbital infrastructure is so critical such as energy or digitaland that any Russian aggression could paralyze not only defense, but European civil society as a whole. National security is no longer decided solely on the eastern land border, but in a three-dimensional environment where the loss of a single satellite node can destabilize entire sectors. Nuclear beyond the atmosphere. Analysts agree that the most feared scenario is not a specific attack against specific satellites, but the detonation of a nuclear charge in orbitcapable of generating devastating electromagnetic pulses and cascading space junk that would render low orbit useless for decades. Historical precedents, such as try Starfish Prime that destroyed a third of existing satellites in the 1960s, serve as a warning of what it would mean to repeat a similar experiment today, with more than 10,000 active satellites. Such an explosion would kill astronauts, destroy global navigation infrastructure, fossilize the digital economy and cause a domino effect that could move the war from space to Earth. Although some experts hold While Moscow would only resort to such action in a scenario of terminal collapse, the mere existence of these capabilities forces Europe to prepare for a type of conflict that would break the traditional limits of deterrence. Political pressure and a new order. Fear of an orbital conflict has reactivated debates on nuclear disarmamentboth in the United States and in Europe, where legislators are promoting initiatives to revitalize multilateral negotiations that have been stagnant for decades. At the same time, ESA has achieved a record budget (22.1 billion euros) that not only finances its transition towards space security, but also promotes scientific and commercial programs, such as reusable rockets, Martian exploration or new astrobiological missions. This growth, supported by Germany, France, Italy and Spain, reflects the strategic convergence between defense, research and technological sovereignty. In the new scenario, Europe seeks not to be a secondary actor in the face of spatial duopolization between the United States and China, but to develop real autonomy that reduces dependence on private platforms like starlink or American systems such as the space interceptors of the Golden Dome. Militarize space. If you also want, the intersection between russian threatsAmerican technological advances and the European strategic awakening marks the beginning of a stage in which the Earth’s orbit is consolidated as the new global scenario military competition. What was once a scientific and commercial domain has become a space where the resilience of entire societies is decided. He ERS projectthe expansion of national space commands and the growing funding of dual capabilities make up a defense ecosystem that seeks to avoid a conflict that no one wants to imagine. And in that scenario, Europe seems to have understood that the only way to deter orbital escalation is to demonstrate that it has the same means to resist it, respond to it and recover.

PLD Space, one step away from becoming the company that has developed an orbital rocket the fastest

Whether in the Elche factory, on a test bench at Teruel airport or on the launch pad under construction in French Guiana, PLD Space is abuzz. The company advances one milestone per week and he tells us why: the Miura 5 rocket is practically ready at the design level. “I would tell you that it is 99%,” says Raúl Torres, CEO of the company, in an interview with Xataka. Candidate to become the Europe’s first private orbital rocketthe Miura 5 is about to finish the Critical Design Review (CDR) and take shape for the first time. “Now we are finishing the QM1 qualification models and starting the QM2, which means that shortly, and I’ll leave it there, we are going to have a first teachable Miura 5,” he reveals for the first time. This first fully integrated model will not fly, but will allow PLD to close engineering fronts and carry out key tests before the end of the year. If everything goes according to plan, the rocket chosen to take off will begin assembly in January. “The idea would be that in May we would be in Guyana to start doing the combined tests with the French space agency CNES,” confirms Torres, adjusting the schedule that originally pointed to a launch at the end of 2025. It is not an unexpected adjustment, but it was pending official confirmation since Chris Larmour, founder of Orbex, PLD’s British competitor, 1,000 euros were bet with Raúl Torres that the Miura 5 would not fly in 2025. Raúl accepted the bet. Will he pay Larmour now? “We have invited him to come sign the rocket at the end of the year, we are waiting for him to answer us,” says Torres. “I would like Orbex to also invite me at the end of the year to sign their rocket. Mine is going to sign it, so I only have to pay half of the bet.” Works in Guayana, lighting in Teruel If the Miura 5 flies in early 2026, PLD Space will be one of the fastest companies to have developed an orbital launcher, which is even more impressive considering the Spanish company’s financing compared to several of its competitors. But PLD Space is not starting from scratch. The successful launch of the Miura 1 suborbital rocket in October 2023 was the graduation of a team that now faces a higher challenge. “Miura 1 has been like primary school, ESO and high school, and now we are at university,” explains Torres. “That is why we have developed Miura 5 so quickly, because we have gone one step ahead with many developments.” Technologies such as the stage power system, cryogenic protections or the welding techniques of the Miura 5 are a direct inheritance from its little brother. However, “university” brings new and more complicated subjects. The most obvious technological leap is in the Miura 5 engines. The five TEPREL-C of the first stage and the vacuum-optimized TEPREL-C of the second They are beasts of another categoryespecially due to the introduction of turbopumps. PLD has developed most of the critical components in-house, such as liquid oxygen and kerosene valves. Combustion chambers are manufactured by electroplating copper and nickel, turbopump housings are 3D printed, and high-precision rotating components are machined. The objective is to achieve a production rate that allows one engine to be manufactured every two weeks in the Elche warehouse. PLD Space passed a fundamental milestone on October 6 with the first static ignition of a fully integrated TEPREL-C Vac in its facilities at Teruel airport. With 75 kN of thrust, it is one of the most powerful vacuum engines ever powered by a private company in Europe. But the real muscle of the rocket will be in the five TEPREL-C engines responsible for takeoff. Each one has 190 kN of thrust, almost double than its competitors. When will we see the first roar of a Miura 5 with the TEPREL-C fully integrated? “In one quarter you should expect the long and qualification tests of both the first and second stages, and also the restart test of both engines,” Torres told Xataka. To validate each component, PLD Space has also deployed new infrastructure at the Teruel airport. The T3 bench has been the protagonist of the static and compression tests of the rocket structures. Valves and gas generators are tested on bench T6. Bench T7 will be used for qualification of first stage Teprel-C engines and second stage long duration ignitions. The T9 bench will be used to test the separation between the first and second stages. Meanwhile, thousands of kilometers across the Atlantic, PLD Space construction in French Guiana has begun. PLD has become the first New Space company to begin construction of its own launch base at the Guyana Space Center. “It is very likely that Miura 5 will be before Kourou’s works,” says Torres. The first structures of the launch pad They are being built in Spain. The rocket should arrive in South America in May. Advances in reuse since flight 1 Inspired by SpaceX, PLD does not conceive of a modern launcher without reuse. And their plan for the Miura 5 is to start collecting landing data from the first flight. If it achieves stage separation on its debut launch, the rocket will perform a maneuver boostback like that of the Falcon 9. “In flight one mission, in the test flight that we will do next year, we are going to try to re-enter the stage,” confirms Torres. After separation, the rocket will turn around and turn on its central engine for a few seconds to brake. “The booster will be ready to re-enter. We don’t want to miss the slightest opportunity to collect data.” And he talks about data because he does not expect to recover the rocket. “Evidently, it’s not going to happen the first time.” The first flight won’t even have a parachute. The main objective is to survive reentry from a hypersonic speed at Mach … Read more

An orbital computing network designed for AI

Just a few minutes after noon on May 14, a Long March 2D rocket took off from Jiuquan’s launch center with an ambitious objective: to put into orbit the first 12 satellites of the “Three-Body” computer constellation. It is the official beginning of which China presents as the first supercomputing network distributed in space, a movement that marks a before and after in the race to move artificial intelligence beyond traditional data centers. A scale jump: from data centers to space. The constellation, led by Zhejiang Lab and developed in collaboration with the company Guoxing Yuhang (Ada Space), is part of the so -called “Star Computing Plan”. This first mission, called 021, has placed in the same orbit 12 smart satellites with names that honor Chinese cities such as Neijiang, Haikou or Taizhou. Each of them is equipped with an intelligent calculation system and laser connectivity up to 100 GB/s to form an interconnected orbital network. According to the official information published by the Chinese Government and collected by media like Xinhuathese first satellites total a capacity of 5 pops (peta-operations per second) and have in conjunction of 30 TB of storage on board. What are pops? HkexNews explains that 1 pops equals a four -year period (10^15) of operations per second. China’s goal is to deploy a constellation that, According to the information that Spacenews managescould reach 2,800 satellites, with a total capacity of 1,000 POPs. An orbit laboratory. Each satellite has a space computer developed by Zhejiang Lab, with a capacity of up to 744 tops (thera-operations per second) per unit. In addition, they are accompanied by a model of 8,000 million parameters, specially designed to operate directly into orbit. This allows real -time data processing tasks without the need to send all the information to land stations. Use cases: from natural disasters to astronomical science. The satellites They are designed To offer very specific services: Gamma ray detection, generation of 3D digital twins of entire regions, remote observation with processing on board and monitoring of natural phenomena. One of them even includes an x ​​-ray polarimeter Developed by the Chinese Academy of Sciences and the University of Guangxi, designed to detect Gamma explosions and activate in second coordinated observations with other missions. Besides, According to Ada Space herselfthe data collected will also serve for civil applications such as emergencies, immersive video games and smart tourism. A orbital cloud under sovereign control. Behind the deployment there is a geostrategic ambition: build a spatial computing infrastructure under Chinese control that combines global coverage with energy efficiency and low latency. Unlike land data centers, satellites can use solar energy continuously and do not require active cooling systems. What’s coming: more power, more satellites. Ada Space has already confirmed that is working on a second generation of satellites with even more power. The objective is clear: validate the computing architecture distributed in orbit, climb it and turn it into the nucleus of a space cloud capable of operating large -scale AI models without depending on the terrestrial infrastructure.
