The Race to Put Data Centers in Space: Starcloud’s Bold 88,000-Satellite Plan
The future of data processing may not be on Earth. A new wave of companies, led by Washington-based startup Starcloud, is looking to move data centers into orbit. On March 13, Starcloud filed an application with the Federal Communications Commission (FCC) to deploy a constellation of up to 88,000 satellites, designed to function as orbital data centers for artificial intelligence and other demanding applications.
Why Space Data Centers? The AI Demand
The driving force behind this ambitious move is the insatiable appetite for computing power fueled by the rapid growth of artificial intelligence. Starcloud argues that traditional data centers are hitting scalability roadblocks. “By avoiding the constraints of terrestrial deployment, space datacenters will be the most cost-effective and scalable way to deliver compute this decade,” the company stated in its FCC filing. Space offers advantages like near-constant solar power, efficient radiative cooling, and the potential for significantly larger scale than is feasible on the ground.
Starcloud’s Vision: From Prototype to Massive Constellation
Starcloud isn’t starting from scratch. The company has already launched Starcloud-1, a 60-kilogram satellite equipped with an Nvidia H100 processor. This satellite successfully ran a version of Google’s Gemini AI model in orbit, demonstrating the viability of the concept. The company is planning Starcloud-2, scheduled for launch in 2027, and further constellations, Starcloud-3 and Starcloud-4. The latter, according to a video on the company’s website, envisions massive satellites with arrays four kilometers on a side, supporting a five-gigawatt data center.
The Competition: SpaceX and Beyond
Starcloud isn’t alone in this endeavor. SpaceX filed plans with the FCC in January to develop a constellation of up to one million orbital data center satellites. Other industry giants, like Amazon (through Project Kuiper) and Blue Origin (Tera Wave), are also exploring space-based communication infrastructure that could support these data centers. However, some skepticism remains. Amazon Web Services CEO Matt Garman recently noted the current limitations in rocket launch capacity, although OpenAI’s Sam Altman doesn’t anticipate space data centers providing significant compute power for at least five years.
Addressing Concerns: Sustainability and Space Debris
Starcloud acknowledges the importance of responsible space operations. The company states its satellites are “designed for full demisability,” meaning they will burn up entirely upon reentry, preventing debris from reaching the ground. They also plan to coordinate with other satellite operators and implement brightness mitigation measures to minimize impact on astronomical observations.
How Will It Work? Inter-Satellite Links and Ground Communication
The Starcloud constellation, like SpaceX’s proposed system, will rely on optical intersatellite data links. In other words satellites will communicate with each other in orbit, and then connect to ground-based broadband systems like Starlink, Project Kuiper, and Tera Wave for broader connectivity. The FCC filing also requests authorization for Ka-band spectrum for telemetry, tracking, and control communications.
Frequently Asked Questions
What is a space data center? A space data center is a facility for processing data located in orbit around Earth, leveraging the unique advantages of the space environment.
Why use satellites for data centers? Satellites offer near-constant solar power, efficient cooling, and the potential for greater scalability compared to ground-based data centers.
How many satellites are currently in orbit? Approximately 14,500 satellites are currently orbiting Earth, with around 9,600 belonging to SpaceX.
What is Starcloud-1? Starcloud-1 is the company’s first satellite, launched in November, featuring an Nvidia H100 processor and used to run AI models in orbit.
What are the concerns about space debris? The increasing number of satellites raises concerns about space debris and the potential for collisions. Companies like Starcloud are designing satellites for full demisability to mitigate this risk.
