Google is discussing future launch choices with SpaceX and different corporations for Venture Suncatcher, a analysis effort into orbital AI information centres. The challenge is designed to check whether or not AI computing infrastructure can function in orbit.
The challenge centres on a community of solar-powered satellites carrying Google’s Tensor Processing Items, or TPUs. The satellites would use free-space optical hyperlinks to maneuver information between one another.
Google plans to launch an preliminary studying mission with Planet Labs in early 2027. In accordance with Google’s analysis publish, the mission is predicted to contain two prototype satellites that may take a look at its {hardware} and design in orbit.
Reuters reported that Google confirmed the launch discussions on Tuesday, after The Wall Road Journal first reported the event.
Google’s Venture Suncatcher analysis additionally discusses energy availability in orbit. In its analysis, it mentioned satellites in sure orbits can entry photo voltaic power extra persistently than ground-based programs. These satellites would additionally keep away from the day-night cycle and climate circumstances that have an effect on photo voltaic era on Earth.
Google’s analysis additionally compares launch prices with terrestrial information centre power prices. Knowledge Centre Dynamics, citing Google’s analysis, reported that US information centre energy prices are estimated at about US$570 to US$3,000 per kW per 12 months.
Google’s paper mentioned launch prices to low Earth orbit would wish to fall to about US$200 per kg. At that degree, the launch value unfold in a spacecraft’s working life might turn out to be roughly comparable with terrestrial information centre power prices on a per-kW foundation. The comparability depends upon launch prices falling to that degree, and is unique of any prices of working an information centre in orbit.
Google’s analysis identifies a number of technical areas that want additional work. It proposes optical communication between satellites and constellation coordination. It additionally factors to points round radiation sturdiness (digital parts uncovered to the radiation of house), thermal design ( cool tools in a vacuum), and deployment economics (the price of getting payloads into orbit).
SpaceX’s AI infrastructure hyperlinks
The launch discussions contain SpaceX as a potential launch supplier for Venture Suncatcher. SpaceX has expertise launching giant satellite tv for pc constellations by Starlink and operates reusable rockets which might be central to its launch enterprise.
SpaceX has additionally been tied to a different AI infrastructure settlement. Reuters reported that Anthropic agreed final week to make use of the total computing energy of SpaceX’s Colossus 1 facility in Memphis. Anthropic additionally expressed curiosity in working with SpaceX on a number of gigawatts of space-based orbital information centres, though no plans have been printed nor funds dedicated.
Google’s deliberate prototype with Planet Labs is the following acknowledged step for Venture Suncatcher. Planet Labs already operates Earth-imaging satellites and is Google’s accomplice for the primary take a look at section.
