Jeff Bezos envisions space-based data centers in 10 to 20 years -- could allow for natural cooling and more effective solar power
Jeff Bezos predicts that within the next 10 to 20 years, extremely large-scale data centers will be constructed in orbit, where continuous access to solar power and relatively easy cooling could allow them to surpass Earth-based facilities in efficiency and cost, reports Reuters. However, building a data center in space will require a number of breakthroughs as it is commercially unfeasible today. "One of the things that is going to happen in the next -- it is hard to know exactly when, it is 10+ years, and I bet it is not more than 20 years -- we are going to start building these giant gigawatt data centers in space," said the Amazon and Blue Origin founder during a discussion with Ferrari chairman John Elkann at Italian Tech Week in Turin, Italy. The global rise of AI and cloud-based technologies is pushing the limits of existing computing infrastructure in terms of power supply and cooling, which has led companies to consider new options for locating these massive data centers. Some believe it makes sense to locate data centers on ships, others think about constructing them in northern countries, there are even thoughts about placing them deep in the ocean. According to Bezos, outer space provides a solar power source that is not subject to atmospheric or weather disruptions. Without clouds, rain, or night cycles, energy collection becomes far more consistent, which makes solar power practical for 24/7 applications. Meanwhile, temperatures in space vary from -120 degrees celsius in direct sunlight to -270 C in the shadow, which greatly simplifies cooling. This could make orbital clusters ideal for intensive computational tasks like AI model training, which demand constant and massive power input. It is technically feasible to generate about 1 GW of continuous electrical power in Earth orbit using solar panels, but the scale is immense, creating massive difficulties. Solar constant on earth is around 1,366W/m2, it should be around the same on the Earth orbit. High-efficiency triple-junction solar cells can convert about 35% of that into electricity, and after accounting for system-level losses like wiring, thermal inefficiency, and other factors, the net usable output is typically 300 - 410 W/m² depending on various factors. That means the project would need 2.4 to 3.3 million square meters of solar panel area -- roughly equivalent to a square array between 1.56 and 1.82 km per side. Such an array would likely weigh 9,000 - 11,250 metric tons just for the photovoltaic material, not including structural supports, power routing, and control electronics. Lifting 9,000 - 11,250 metric tons of space-grade solar panels into low Earth orbit (LEO) using today's best commercial launch vehicles -- such as SpaceX's Falcon Heavy with an up to 64 metric tons payload -- would cost between $13.7 and $17.1 billion at an optimistic ~$1,520/kg, assuming near-max efficiency in payload mass per launch. However, at a more conservative cost of over $2,000/kg, that cost will increase to $25+ billions and will require well over 150 launches only for solar panels. In addition, nearly all of the input power becomes heat, which must be radiated into space, which means millions of square meters of radiators to handle 1+ GW of thermal load. How much will such radiators weigh and how much will cost lifting them to space is something that remains to be seen, but since radiators tend to weigh more than solar panels, we are talking about tens of billions of dollars here. Last but not least, actual AI servers equipment also weighs tens of thousands of metric tons and costs tens of billions of dollars even on earth. So while possible in principle, the logistical, economic, and engineering challenges of assembling and maintaining such an orbital power system are enormous.

Jeff Bezos Predicts We'll Have Gigawatt Data Centers in Space in 20 Years
When he's not battling bugs and robots in Helldivers 2, Michael is reporting on AI, satellites, cybersecurity, PCs, and tech policy. Don't miss out on our latest stories. Add PCMag as a preferred source on Google. As major tech companies race to build massive data centers for next-generation AI, Amazon founder Jeff Bezos is looking further ahead, with plans to one day place data centers in space. At Italian Tech Week 2025, Bezos was asked to predict what the world might look like in the years to come. In response, the billionaire discussed his rocket company, Blue Origin, before talking about the construction of data centers in Earth's orbit. "It's hard to know exactly when -- it's 10 plus years, but I bet it's not more than 20 years -- we're going to start building these giant gigawatt data centers in space," he said. The idea may sound far-fetched. However, others, including startup Lumen Orbit, have also discussed operating data centers from orbit, citing the abundant solar energy and cooling capabilities. Bezos mentioned the same energy benefit. "So these giant training clusters, those will be better built in space because we have solar power there, 24/7. And the solar power there, there are no clouds, no rain, no weather," he added. "We will be able to beat the cost of terrestrial data centers in space in the next couple of decades." Orbital data centers could also help address the soaring energy costs associated with building them on Earth. OpenAI, Meta, and Elon Musk's xAI are all planning to erect massive data centers across the US, which will require multiple gigawatts of energy and the construction of numerous new power plants. (For perspective, the Hoover Dam generates about 2 gigawatts.) Presumably, the same data centers could beam data back and forth using lasers. However, launching and operating them from orbit is easier said than done. Bezos is essentially betting that Blue Origin will one day have reusable rockets large enough to haul data centers into space. Currently, the company's heavy-lift launch vehicle, New Glenn, is still preparing for its second launch; the craft has also not yet achieved a successful booster landing. Still, Bezos is predicting we won't just have data centers in space, but people living there as well. "In the next kind of couple of decades, I believe there will be millions of people living in space. That's how fast this is going to accelerate," he said.

Bezos dreams of orbital datacenters powered by the sun
Aspiring Bond villain believes the best place to train our AI overlords is in orbit Amazon founder and executive chair Jeff Bezos says that, within two decades, gigawatt-scale datacenters powered by a continuous stream of photons from the sun will fill Earth's orbit. Bezos' prediction might sound like he's auditioning for the role of Hugo Drax in the inevitable Moonraker reboot, but the billionaire businessman really believes that spaceborne datacenters are going to be a thing and may eventually outperform their terrestrial counterparts. "One of the things that's going to happen in the next - it's hard to know exactly when, it's 10 plus years, and I bet it's not more than 20 years - we're going to start building these giant gigawatt datacenters in space," he said during a fireside chat with Ferrari and Stellantis chair John Elkann, at Italian Tech Week. Of course, to make this dream a reality, we're going to need heavy lift rockets capable of shuttling the various components to and from orbit, which Bezos' Blue Origin just so happens to be building. However, even if we can make putting bit barns in orbit economical, there is no shortage of challenges to overcome. Datacenters are massively complex facilities. Even with an abundant supply of power, an orbital datacenter would still need a way to reject a gigawatt of thermal energy through radiation. For reference, the ISS's radiators are capable of rejecting about 70 kilowatts of thermal energy. Bit barn operators will also have to contend with bit-flips on a fairly regular basis unless the hull can be sufficiently hardened against charged particles from the sun and cosmic rays from the outer reaches of space -- standard ECC probably isn't going to cut it. Many of these challenges are already being tackled at a smaller scale. HPE has been working on the problem for several years now with Spaceborne and Spaceborne-2. These systems have made several trips to the International Space Station already and have tested things like edge compute storage and recovery on long-term space missions. The first unit, launched in 2017, experienced several failures during its 615-day mission aboard the ISS. As HPE's Dr Eng Lim Goh told The Register at the time, one of the machine's four redundant power supplies and nine of its 20 SSDs encountered issues. Axiom Space has also launched a similar compute prototype to the ISS. In August, the startup's shoebox-sized Data Center Unit One (AxDCU-1) arrived on the space station. However, all of these designs have been tiny power-optimized designs and are nothing like the kinds of data stations Bezos is describing. Orbital datacenter advocates expect full scale facilities will require high degrees of automation, including the extensive use of robots to perform maintenance or upgrades. But while most of the challenges facing spaceborne datacenters are engineering and economic in nature, there's one that can't easily be overcome, at least not without bending the laws of physics: latency. We think about the speed of light being practically instantaneous, but it's very much not. Depending on how high up these datacenters are parked, access latencies will be on the order of 20-40ms for low Earth orbit and upwards of 600ms for Geostationary satellites. That's an eternity compared to terrestrial datacenter networks. While these facilities may be untenable for certain workloads, for other less-latency-sensitive, more power-hungry workloads, they may be ideal, Bezos argues. "These giant training clusters, those will be better built in space, because we have solar power there, 24/7 ... There are no clouds and no rain, no weather," Bezos said. "We will be able to beat the cost of terrestrial datacenters in space in the next couple of decades." ®

From Earth to orbit: Jeff Bezos outlines bold vision for space-based data centres
Jeff Bezos projects space data centres within two decades. These facilities will operate with energy efficiency and reliability. They will use constant solar power. Bezos sees this as a next step for space infrastructure. Orbital centres will support the computing needs of AI development. This model aims for computing sustainability. Launch costs and radiation present challenges. Amazon founder and executive chair Jeff Bezos has projected that data centres could be built in space within the next 10 to 20 years. Speaking at the Italian Tech Week in Turin, he stated that space-based facilities could outperform those on Earth in terms of energy efficiency and reliability due to access to constant, uninterrupted solar power, as per a report by TOI. Bezos described orbiting data centres as a logical next step in the evolution of space infrastructure, which he said has already enhanced life on Earth through satellite-based weather monitoring and global telecommunications. He likened the current artificial intelligence (AI) boom to the internet surge of the early 2000s, noting that while speculation is to be expected, the long-term societal benefits of AI are significant. Bezos argued that orbital data centres would enjoy unique operational advantages over terrestrial facilities. These include continuous solar energy availability, freedom from weather-related disruptions, and the absence of environmental constraints found on Earth. He suggested that space-based facilities could operate at "unprecedented efficiency" and envisions "gigawatt-scale" systems capable of managing the intense computational needs of AI development. According to Bezos, such centres could transform how large AI models are trained, how data is stored, and how cloud services are delivered. Positioning them in orbit would reduce energy consumption, cooling requirements, and environmental impacts, presenting a more sustainable model for the technology sector. He referenced satellites as proof of concept, noting their contributions to weather forecasting, GPS, and communication systems. In his view, data centres are the next practical application of space technology. He also pointed to potential future uses such as in-orbit manufacturing and research that requires extreme environmental conditions. Despite the potential, Bezos acknowledged several challenges. Launching heavy infrastructure into space remains costly, and carries risks such as launch failure or damage during transport. Maintenance is complicated by limited human access, making reliable robotic servicing essential. Radiation in space also poses a risk to electronic equipment, requiring robust system designs to withstand harsh conditions. Nonetheless, Bezos expressed confidence that progress in space transportation, solar power collection, and robotics will ultimately make orbital data centres a viable and cost-effective option. Bezos compared the rapid growth of AI to the early internet era, noting that while hype is inevitable, the underlying technological progress is real. He stated that AI holds the potential to improve sectors including healthcare, education, finance, and manufacturing. He argued that orbital data centres could support this progress by providing the extensive computational power required for AI research and training. According to Bezos, the benefits of AI are expected to be broadly distributed, fostering global innovation, job creation, and long-term technological advancement.

Jeff Bezos makes wild prediction about data centers as energy demand...
Amazon founder and executive chair Jeff Bezos said Friday gigawatt-scale data centers will be built in space within the next 10 to 20 years, predicting they would eventually outperform Earth-based ones thanks to the abundance of uninterrupted solar energy. The number of these enormous centers, which store computing infrastructure, is growing exponentially as the world increasingly uses artificial intelligence and cloud computing, driving a surge in demand for electricity and water to cool their servers. "One of the things that's going to happen in the next - it's hard to know exactly when, it's 10 plus years, and I bet it's not more than 20 years - we're going to start building these giant gigawatt data centers in space," Bezos said during a fireside chat with Ferrari and Stellantis Chairman John Elkann at the Italian Tech Week in Turin. The concept of space-based data centers is gaining traction among large tech companies, as the energy needs to maintain such operations on Earth are growing sharply. "These giant training clusters, those will be better built in space, because we have solar power there, 24/7. There are no clouds and no rain, no weather," Bezos said. "We will be able to beat the cost of terrestrial data centers in space in the next couple of decades." Bezos said the shift to orbital infrastructure is part of a broader trend of using space to improve life on Earth. "It already has happened with weather satellites. It has already happened with communication satellites. The next step is going to be data centers and then other kinds of manufacturing," he said. However, hosting data centers in space has its own challenges, including cumbersome maintenance, limited scope for upgrades and high costs of launching rockets as well as the risk of failed rocket launches.
