Starcloud Raises $250 Million To Build AI Data Centers in Space
Training AI is getting too expensive and too hot. The biggest AI data centers on the ground use a lot of electricity. They also need massive cooling systems. On top The post Starcloud Raises $250 Million To Build AI Data Centers in Space appeared first on Ventureburn .
Starcloud, an AI hardware startup, has secured $250 million in funding to construct data centers in space. The investment round was spearheaded by Manhattan West, with Nvidia, Cisco Investments, and more than a dozen other backers participating. Starcloud first demonstrated its capabilities by launching a single Nvidia graphics card into space, successfully running an AI training job while orbiting Earth.
The company's ultimate goal is to create an array of 88,000 satellites, combining their computing power to reach 20 gigawatts.
Traditional ground-based data centers face two main challenges: power consumption and heat dissipation. AI chips generate significant heat during model training, requiring costly cooling systems. Additionally, data centers consume as much electricity as small cities, with costs constantly rising. In contrast, space offers a naturally cold environment and an abundant source of solar power for energy needs.
Starcloud plans to launch Starcloud-2, the first real system, featuring AI chips, onboard storage, and a data backup module. This satellite will handle both AI training and inference tasks. Subsequent versions, including Starcloud-3 and Starcloud-4, will be mass-produced, each satellite consuming approximately 200 kilowatts of power. Starcloud-3 will include graphics cards along with dedicated cooling and heat-dissipation equipment tailored for space conditions.
The final vision, Starcloud-4, is an expansive cylindrical structure equipped with solar panels spanning 2.5 square miles. Inside, container-sized modules will house liquid-cooled servers, potentially rivaling the largest data centers on Earth without the limitations of land, water, and electricity. Starcloud is currently constructing production lines to mass-produce Starcloud-3 satellites and intends to secure space on rockets through SpaceX, a reported launch partner.
Notably, SpaceX is also developing its own competing AI satellite, "AI1," which will feature a 230-foot wingspan and computing power comparable to Starcloud-3. SpaceX aims to commence mass production by the end of 2027.
