Voyager CEO Discusses Major Cooling Issues in Space Data Centers

TLDR

• Voyager CEO Dylan Taylor emphasizes that cooling is a major challenge for space data centers.
• Taylor explains that heat transfer in space is difficult due to the lack of a medium to dissipate heat.
• All heat in space must be eliminated through radiation, requiring a radiator away from the Sun.
• Voyager Technologies is collaborating with companies like Palantir, Airbus, and Mitsubishi on space data center solutions.
• Voyager has already placed cloud computing equipment aboard the International Space Station.

Voyager Technologies’ CEO Dylan Taylor has highlighted a critical issue facing space data centers: cooling. The company is developing technology to establish data centers in space, but cooling remains a major obstacle. Taylor emphasized that this issue will delay large-scale space data center deployments.

Cooling in Space is a Major Obstacle

Dylan Taylor pointed out that space data centers struggle to dissipate heat effectively. He explained that heat transfer in space is extremely difficult because there is no medium like air to facilitate cooling. “It’s counterintuitive, but it’s hard to actually cool things in space because there’s no medium to transmit heat to cold,” said Taylor.

He further elaborated that the heat in space must be eliminated through radiation. This process requires a radiator that is positioned away from the Sun. Without an effective cooling system, the operation of space data centers becomes highly inefficient and technically challenging.

Voyager CEO Explains Space Data Center Technology

Voyager Technologies, known for its Starlab project, is actively working on space-based infrastructure. Taylor noted that the company is collaborating with major partners such as Palantir, Airbus, and Mitsubishi to push forward their space data center vision. He expressed confidence in the ability to create a working solution for cooling and data processing in space.

Despite these challenges, Taylor remains optimistic about the future. He believes that advancements in laser communication technologies will play a crucial role in overcoming some of the difficulties. Taylor also mentioned that Voyager has already placed cloud computing equipment aboard the International Space Station.

Investment Surge in Space Technologies

Taylor’s comments coincide with a surge in space technology investments. Government spending, particularly in defense-related space initiatives, is fueling interest in this sector. Investment firm Seraphim Space reported a 48% increase in private investment in space technology in 2025, reaching $12.4 billion.

Seraphim Space also noted that U.S. defense spending, particularly related to satellite systems, is driving much of the growth. Taylor’s efforts to develop space data centers align with the broader push for advancements in space technology.
