Voyager Technologies CEO: Cooling Challenges for Space Data Centers Remain Unresolved
Voyager Technologies CEO Dylan Taylor stated that space data centers are likely to become a reality, but cooling issues remain a key obstacle that must be solved for this emerging technology. He believes that deploying space data centers within two years is an "extremely challenging" timeline, as there has yet to be a breakthrough in cooling technology.
Core Cooling Challenge: The Dilemma of Heat Dissipation in a Vacuum Environment
In an interview with CNBC reporter Morgan Brennan, Taylor pointed out that although SpaceX has heavy-lift rockets capable of sending components into space, the lack of effective cooling solutions to dissipate the heat generated by equipment remains the main bottleneck for the development of space data centers.
"It seems counterintuitive, but in the space environment, actually cooling equipment is very difficult because there is no medium to conduct heat," he explained. "All heat dissipation must be achieved through radiation, which means you need a radiator facing away from the sun to complete the cooling process."
In space, the vacuum environment is a perfect thermal insulator, so heat cannot be transferred quickly by convection and must be dissipated slowly through radiation (converting heat into infrared light). This method is extremely inefficient, with each square meter able to radiate only a few hundred watts at most, while large AI clusters require massive passive cooling panels, presenting extremely high demands for radiator design.
Musk's Ambition for Space Computing Power: The Core Motivation Behind the Merger of SpaceX and xAI
Tesla CEO Elon Musk has long been optimistic about the future development of space data centers and has made their construction one of the main reasons for this week's merger between SpaceX and AI startup xAI. This $1.25 trillion deal aims to create a space-based computing power network to solve the core pain points faced by ground data centers, such as high electricity costs and low cooling efficiency.
Musk believes that the current evolution of AI technology heavily relies on large ground data centers, whose energy consumption and cooling needs are staggering. Ground-based energy solutions alone are simply insufficient to fill the global AI electricity gap. Space offers nearly constant solar energy, with no expensive land operation or cooling maintenance costs. By launching a million satellites to form an orbital data center, solar energy can be directly converted into computing power.
Voyager Technologies' Starlab Program: Starlab Space Station and Space Computing Deployment
Voyager Technologies went public in June 2025 and is known for its Starlab project, which plans to replace the International Space Station when it is retired in 2030. Taylor said the company is progressing toward its 2029 launch goal as scheduled and is currently working with Palantir, Airbus, and Mitsubishi to develop the project, having already deployed its own cloud computing equipment on the International Space Station.
Voyager Technologies also plans to leverage its laser communication tools to play a leading role in the field of space data centers. Taylor stated: "We are confident that this technology will gradually mature, and we also believe we have the ability to generate and process data in space."
Investment Boom in the Space Industry: Dual Drivers of Policy Support and Market Expectations
President Donald Trump's plans to increase defense spending and reform the U.S. space program have boosted market interest in space technology investments over the past year. In addition, the highly anticipated SpaceX initial public offering (expected later this year) has also fueled investor enthusiasm.
Last year, as the IPO market reopened after years of stagnation, a wave of space technology companies went public. However, the path isn't always smooth—since Voyager Technologies' listing, its stock price has dropped by more than half, while rocket manufacturer Firefly Aerospace has seen its market value shrink by nearly two-thirds since its IPO in August 2025.
