Aetherflux is set to join the competitive landscape of orbital data centers with plans to launch its first solar-powered satellite in early 2027. This initiative comes at a time when AI workloads are straining existing data center capacities on Earth, prompting several companies, including SpaceX, Amazon, Google, and Starcloud, to pursue off-planet computing solutions.
In its announcement, Aetherflux revealed that the first orbital data center node will be operational by Q1 2027. The company aims to build a constellation of satellites, enhancing capacity to meet the growing demands of AI technologies. According to projections, data center energy consumption may double by 2030, and some estimates suggest that power demand could rise by as much as 160% due to AI’s requirements.
Despite the enthusiasm around orbital computing, only a small fraction of CIOs are incorporating it into their future plans. This hesitance comes even as over 60% acknowledge the challenges posed by energy, land, and permitting constraints in implementing AI infrastructure.
Aetherflux plans to provide multi-gigabit bandwidth and will utilize cutting-edge optical inter-satellite links to ensure comparable performance to terrestrial servers. The approach also involves continuously launching new hardware to integrate the latest technology while utilizing previously deployed systems for lower-priority tasks. The company plans to deploy around 30 satellites simultaneously using SpaceX Falcon 9 rockets and will conduct a power-beaming demonstration in 2026.
While the sector is experiencing rapid growth, analysts believe that orbital data centers will not replace conventional cloud data centers in the near future. They will primarily serve specific applications such as data sovereignty compliance, disaster recovery, and high-performance computing for lengthy batch jobs—activities that can handle the latency associated with low Earth orbit operations.
There are indeed immediate applications like processing satellite-generated data in orbit, enabling more efficient handling of large data without bottlenecks related to downlink capabilities. However, the suitability of space-based workloads is limited to those with low data transfer, latency tolerance, and high energy consumption needs.
Despite claims that energy costs in orbit might be minimal, overall economic viability remains questionable. The capital expenses for launching and maintaining infrastructure in space are considerable, and experts suggest that any advantages gained from lower operational costs could be offset by high launch and maintenance expenses.
Operational and upgrade challenges compound these capital expenses. Unlike terrestrial data centers, once hardware is launched into space, it cannot be easily updated, necessitating a model of treating satellites as disposable items that require frequent replacement, further inflating total ownership costs.
Surprisingly, most CIOs express a preference for at least a 30% to 40% cost advantage before considering orbital solutions. Current market forecasts, nonetheless, predict robust growth in the in-orbit data center market, which could reach $1.77 billion by 2029 and potentially soar to $39.09 billion by 2035.
As the industry evolves, caution is advised. Analysts suggest that for the next few years, orbital data centers should be viewed as part of broader scenario planning rather than a core component of transformation strategies. Experts emphasize that the pursuit of orbital computing should focus on sustainability and availability rather than immediate cost savings, with the realization that significant energy needs can drive this innovative approach forward.
