Google plans to establish a satellite system in Earth’s orbit to harness solar energy for powering data centers, as detailed in the company’s blog<\/a>.<\/p>\n

The corporation views artificial intelligence as a transformative technology with the potential to change the world. However, unlocking its full potential requires significant computational power.<\/p>\n

\n

\u201cThe Sun is the primary energy source in our solar system, emitting energy 100 trillion times greater than the total production of all humanity. In the right orbit, a solar panel can be eight times more efficient than on Earth, producing energy almost continuously and reducing the need for batteries,\u201d the firm asserts.<\/p>\n<\/blockquote>\n

In the future, space could become the optimal location for scaling artificial intelligence, prompting Google to launch the ambitious research project Suncatcher. This initiative involves creating compact groups of solar-powered satellites equipped with the company’s tensor processing units (TPUs) and interconnected through optical communication channels.<\/p>\n

The proposed system will operate in a sun-synchronous low Earth orbit, where devices can receive nearly continuous sunlight exposure and maximize energy collection.<\/p>\n

Challenges<\/h2>\n

Google highlighted several challenges that must be overcome to realize the Suncatcher project.<\/p>\n

Ensuring Inter-Satellite Communication Channels<\/strong><\/p>\n

Large-scale machine learning workloads require task distribution among numerous accelerators with high bandwidth and low latency.<\/p>\n

To achieve performance comparable to terrestrial data centers, communication channels between satellites must support tens of terabits per second. This is feasible through dense multi-channel transceivers<\/span> with wavelength division multiplexing<\/span> and spatial multiplexing<\/span>, according to Google experts.<\/p>\n

Achieving the necessary bandwidth requires levels of received power thousands of times greater than typical for conventional long-range systems.<\/p>\n

\n

\u201cSince input energy is inversely proportional to the square of the distance, we can overcome this issue by launching satellites in a very dense formation,\u201d the blog states.<\/p>\n<\/blockquote>\n

The team has already begun testing this approach. A laboratory prototype achieved data transmission speeds of 800 Gbps in each direction.<\/p>\n

Satellite Management<\/strong><\/p>\n

High-bandwidth inter-satellite communication channels require very dense device placement.<\/p>\n

Experts have developed models to analyze the orbital dynamics of such a cluster. They indicate that with satellites placed only a few hundred meters apart, minor maneuvers will be necessary to maintain stable positioning.<\/p>\n

Radiation Resistance of TPUs<\/strong><\/p>\n

To ensure the resilience of ML<\/span> accelerators, they must withstand the conditions of low Earth orbit. The company tested the Trillium chip, with promising results.<\/p>\n

High-bandwidth memory subsystems began to show instability after accumulating an ionizing dose<\/span> nearly three times the expected level.<\/p>\n

Experts did not observe any significant failures.<\/p>\n

Economic Viability<\/strong><\/p>\n

Previously, high launch costs were the main obstacle to creating large-scale space systems. Data analysis suggests that by the mid-2030s, launch prices could drop to less than $200 per kg.<\/p>\n

At such rates, a space-based data center could become economically comparable to an equivalent terrestrial data center.<\/p>\n

Initial Launches<\/h2>\n

Google emphasized that the primary computations do not contradict fundamental physical laws and do not face insurmountable economic barriers.<\/p>\n

\n

\u201cHowever, significant engineering challenges remain, such as thermal regulation, high-bandwidth ground communication, and orbital system reliability,\u201d the blog notes.<\/p>\n<\/blockquote>\n

Google will begin addressing these issues with a training mission in partnership with Planet, planning to launch two prototype satellites by early 2027. The experiment will test the functionality of models and equipment in space.<\/p>\n

Back in May 2025, China launched<\/a> 12 satellites as part of a project to build a network of orbital supercomputers.<\/p>\n","protected":false},"excerpt":{"rendered":"
