The ambitious vision of space-based data centers, long championed by figures like Elon Musk, faces a significant hurdle: heat. Voyager Technologies CEO Dylan Taylor recently highlighted this challenge, stating that a two-year timeline for deploying such infrastructure is “aggressive” primarily due to the lack of effective cooling solutions in the vacuum of space.
While the heavy-lift capabilities of companies like SpaceX are essential for transporting components into orbit, the fundamental physics of heat transfer presents a unique problem. “It’s counterintuitive, but it’s hard to actually cool things in space because there’s no medium to transmit hot to cold,” Taylor explained. “So essentially, all heat dissipation has to happen via radiation, which means you need to have a radiator pointing away from the sun to do that.” This necessity for large, precisely oriented radiators adds complexity and mass to any space-based computing endeavor.
Musk’s recent moves, including the proposed merger of SpaceX and xAI, signal a strong commitment to building a future where data centers reside beyond Earth’s atmosphere. This vision is seen as a critical component for scaling advanced AI models and handling the massive data flows anticipated from a burgeoning space economy.
Voyager Technologies, a company that recently went public, is a key player in this evolving landscape. Its flagship project, Starlab, is being developed to succeed the International Space Station, which is slated for decommissioning in 2030. Taylor confirmed that Starlab remains on track for its projected 2029 launch, a development being pursued in partnership with industry leaders such as Palantir, Airbus, and Mitsubishi. The company already has a foothold in orbit with its own cloud compute device currently aboard the ISS.
The broader interest in space technology investment has been bolstered by geopolitical factors, including projected increases in defense spending and a renewed focus on national space programs. Furthermore, the much-anticipated public offering of SpaceX is expected to further energize the market.
However, the path for space tech companies has not been without its challenges. Following a period of intense activity, the sector has seen significant stock fluctuations. Voyager’s shares, for instance, have experienced a substantial decline since its initial public offering, and fellow rocket maker Firefly Aerospace has also seen a considerable drop in its market value since its August debut.
Despite these market headwinds, Voyager Technologies believes its laser communication tools position it to be a leader in the development of space-based data processing. “We’re big believers in the technology maturing and our ability to generate data in space and process data in space,” Taylor asserted, underscoring the company’s confidence in overcoming the technical hurdles associated with operating in the unique environment of space.
