Mengzhou spacecraft for China's moon-landing mission passes landmark test flight
China has completed the inaugural test flight of its next-generation Mengzhou crewed spacecraft , executing a critical zero-altitude escape trial at the Jiuquan Satellite Launch Centre in the Gobi Desert. Advertisement Developed for China's 2030 lunar ambitions , the modular Mengzhou spacecraft features two variants: a near-Earth version supporting space station operations with a seven-astronaut capacity and a deep-space model for lunar missions. Its reusable return capsule and advanced technologies place it among the world's most capable crew vehicles. 01:57 China's Chang'e-6 mission returns to Earth with first samples from moon's far side China's Chang'e-6 mission returns to Earth with first samples from moon's far side At midday on Tuesday, the spacecraft's escape engines ignited while grounded at the launch complex. Within 20 seconds, the return capsule reached its designated altitude and cleanly separated from the escape tower as parachutes deployed. The capsule subsequently touched down within the predetermined landing zone using an airbag cushioning system, marking the test's success. This foundational safety verification – designed to ensure crew survive during rocket failures at lift-off – simulates emergencies in which astronauts must be rapidly extracted from danger zones during a vehicle's most vulnerable launch phase.

China just started building an AI supercomputer in space
When you buy through links on our articles, Future and its syndication partners may earn a commission. China has launched its first cluster of satellites for a planned artificial intelligence (AI) supercomputer constellation in space. The 12 satellites are the beginnings of a proposed 2,800-satellite fleet led by the company ADA Space and Zhejiang Lab that will one day form the Three-Body Computing Constellation, a satellite network that will directly process data in space. The satellites, which launched on board a Long March 2D rocket from China's Jiuquan Satellite Launch Center May 14, are part of a plan to lower China's dependence on ground-based computers. Instead, the satellites will use the cold vacuum of space as a natural cooling system while they crunch data with a combined computing capacity of 1,000 peta (1 quintillion) operations per second, according to the Chinese government. "It's a good time to think about how we can put AI into space, not just in your laptop or cellphone," Wang Jian, director of Zhejiang Lab, said at the Beyond Expo tech conference in Macau Wednesday (May 21), the South China Morning Post (SCMP) reported. "Space has, again, become the frontier for us to think about what we can do in the next 10, 20 or 50 years." Whether satellites are used for GPS systems, climate sensors, telescopes, weather forecasting or communication, many organizations increasingly rely on the observations made by orbiting spacecraft. But this raw data needs to be crunched back on Earth, meaning it's limited by transmission bandwidths and the narrow windows it can be sent as satellites pass over ground stations, meaning a lot of it is lost. Related: China plans to build enormous solar array in space — and it could collect more energy in a year than 'all the oil on Earth' To overcome this restriction, companies have begun designing satellites capable of "edge computing," where raw data is processed on board the satellite before being transmitted down to the ground. Doing these energy-intensive computations in orbit also allows the satellites' power to be drawn from solar panels and their waste heat radiated into space, thereby lowering their carbon footprint. Each satellite in China's launch contains an 8 billion-parameter AI model that can perform 744 tera operations per second (TOPS), according to a translated ADA Space statement, with the number shooting up to five peta operations per second when their processing power is combined. For reference, Microsoft's AI Copilot+ laptops can currently process at a rate of around 40 TOPS. Orbiting in an array, the satellites will communicate with each other using lasers, one of which is equipped with an X-ray polarization detector for studying cosmic phenomena such as gamma-ray bursts. The computing constellation gets its name from the three-body problem, a question first formulated by Isaac Newton that involves predicting the chaotic motion of three objects orbiting each other under the effects of gravity. The quandary served as inspiration for the renowned science-fiction trilogy of the same name written by Chinese author Liu Cixin, alongside a Netflix adaptation. This initial inspiration carries over to the purported aims of the constellation, according to Wang, who highlighted the complexities of working with multiple entities in a call for increased international cooperation in the project. He claimed that the array will permit other international organizations to build and use its computers, the SCMP reported. Although the U.S. and Europe have performed tests on space computers, China's array is the first to be deployed at an operable scale. Meanwhile, former Google CEO Eric Schmidt, following his purchase of a controlling interest in the California launch company Relativity Space, has proposed launching data centers into orbit.

"It gives you a sense of how big this crisis is." "One of the estimates that I think is most likely is that data centers will require an additional 29 gigawatts of power by 2027, and 67 more gigawatts by 2030," he added. "These things are industrial at a scale that I have never seen in my life."

China Is Building an AI-Powered Supercomputer Network in Space
China is launching a space-bound AI supercomputer — and the first batch of the satellites it's comprised of was just sent up. As the South China Morning Post reports, the so-called "Three-Body Computing Constellation" project launched the first 12 of its planned 2,800 satellites last week from the Jiuquan Satellite Launch Center in northwest China. The orbital supercomputer network will, when complete, allow for rapid in-orbit data processing rather than relying on terrestrial computing facilities to relay information to Earth and then back up to space. It also doesn't require the copious amounts of water ground-based computers need to stay cool. Each satellite, the SCMP notes, carries an eight-billion-parameter AI model that can process raw data in orbit. Paired with the satellites' massive computing power of one quintillion operations per second, the constellation is expected, when complete, to rival the world's most powerful terrestrial supercomputers. Launched from northwest China's Jiuquan Satellite Launch Center, each satellite carries, per a statement from the ADA Space startup that helped launch the constellation, unique scientific payloads that can do everything from detect gamma ray bursts to create "digital twins" of Earth terrain for emergency services and other industries. While the concept of orbital computing is nothing new, this project is, as Harvard astronomer Jonathan McDowell told SCMP, "the first substantial flight test" of the gambit. As McDowell pointed out, theoretical space cloud computing projects are "very fashionable" right now, with private companies like Axiom Space and Jeff Bezos' Blue Origin planning their own orbital computing satellites. Unlike terrestrial data centers, which, according to the International Energy Agency are on track to use as much energy as Japan by 2026, orbital data centers can "use solar power and radiate their heat to space, reducing the energy needs and carbon footprint," as McDowell told SCMP. With the launch of the first of its 2,800 satellites, China's orbital supercomputer puts the country ahead of the United States in the rival countries' space race, though there's no telling which will actually cross the finish line first.
