Placing AI in area might sound like a sci-fi nightmare, however Google is considering the concept with a analysis endeavor referred to as Project Suncatcher. The concept is to place power-hungry knowledge facilities into orbit on solar-powered satellites, to allow them to be powered by limitless, clear power out there 24 hours a day. That may mitigate the nastiest points of AI cloud computing, like the usage of energy vegetation that spew big quantities of CO2 into the environment.

Mission Suncatcher is a literal moonshot of the sort that Google used to do extra typically. The search big needs to place its AI chips, referred to as Tensor Processing Items (TPUs), into orbit aboard photo voltaic panel-equipped satellites. “Sooner or later, area could also be the most effective place to scale AI compute,” wrote Google senior director Travis Beals. “In the best orbit, a photo voltaic panel may be as much as 8 instances extra productive than on Earth, and produce energy almost constantly, decreasing the necessity for batteries.”

Suffice to say, the concept poses quite a few challenges. That proximity to the solar would expose the TPUs to excessive ranges of radiation that may quickly degrade digital elements. Nonetheless, Google has examined its present chips for radiation tolerance and stated they’d have the ability to survive a 5 12 months mission with out struggling everlasting failures.

One other problem is the high-speed knowledge hyperlinks of “tens of terabits per second” and low latency required between satellites. These speeds can be exhausting to realize in area, as transmitting knowledge at lengthy distances requires exponentially extra energy than on Earth. To attain that, Google stated it might must maneuver TPU-equipped satellites into tight formations, probably inside “kilometers or much less” of one another. That may have the additional benefit of decreasing “station holding” thrust maneuvers wanted to maintain the satellites in the best place.

The figuring out issue, although, is cash. Launching TPUs into area might not appear cost-efficient, however Google’s evaluation reveals that doing so could possibly be “roughly comparable” to knowledge facilities on Earth (by way of energy effectivity) by across the mid-2030s.

Whereas it is presently solely a preliminary research paper, Google is planning to place Mission Suncatcher via some preliminary trials. It has teamed with an organization referred to as Planet on a “studying mission” to launch a pair of prototype satellites into orbit by 2027. “This experiment will take a look at how our fashions and TPU {hardware} function in area and validate the usage of optical inter-satellite hyperlinks for distributed ML [machine learning] duties,” Google wrote.
