Corporations are once again competing in a space race, but this time it’s not about reaching the moon or Mars; it’s about harnessing the potential of data processing in orbit. Following Starcloud’s recent launch of its Starcloud-1 satellite, equipped with an Nvidia H100 GPU for AI processing in space, major players like Google and SpaceX are eager to join the fray. Starcloud, previously known as Lumen Orbit, had initially proposed this ambitious concept last year, though the current setup—a singular computer—offers only a glimpse of what’s possible compared to traditional data centers.
Elon Musk chimed in on the development, mentioning in a social media post that SpaceX could enhance its Starlink V3 satellites to support this initiative. While he remained vague about specific plans, his assertion suggested a straightforward scaling approach.
On the other hand, Google unveiled plans for Project Suncatcher, aimed at creating a solar-powered satellite constellation equipped with tensor processing units (TPUs). According to the company’s press release, this endeavor seeks to build a scalable infrastructure for machine learning in space, although it relies heavily on theoretical research that hasn’t undergone peer review yet. The project is projected to become financially viable around the mid-2030s.
Despite the excitement, experts caution that significant technological challenges remain before a functional space data center can be realized. Peter Judge, an analyst from the Uptime Institute, highlighted the need to address numerous technical hurdles before establishing data centers in orbit.
There are compelling reasons behind the interest in space-based data centers. Many reports suggest that increasing AI processing demands are straining terrestrial centers’ power consumption, with projections indicating annual growth rates of 26% to 36%. This has prompted organizations to explore alternative solutions.
Another critical factor is the growing data volume generated by satellites, which often exceeds what can be transmitted back to Earth due to bandwidth limitations. By equipping satellites with AI processing capabilities, they could analyze more data on-site, returning only valuable insights. Judge emphasizes that the push for space processing is increasingly driven by the demands of satellite data handling.
Moreover, China’s space computing efforts seem to be advancing rapidly. Last year, Guoxing Aerospace launched a series of 12 satellites to create a space-based computing network known as the Three-Body Computing Constellation. Ultimately, this network aims to consist of 2,800 satellites dedicated to data orchestration and processing, taking edge computing to unprecedented heights.
