Google is discussing future launch choices with SpaceX and different corporations for Venture Suncatcher, a analysis effort into orbital AI information centres. The mission is designed to check whether or not AI computing infrastructure can function in orbit.
The mission centres on a community of solar-powered satellites carrying Google’s Tensor Processing Models, 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 put up, the mission is predicted to contain two prototype satellites that can 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 stated satellites in sure orbits can entry photo voltaic vitality extra persistently than ground-based methods. These satellites would additionally keep away from the day-night cycle and climate situations that have an effect on photo voltaic era on Earth.
Google’s analysis additionally compares launch prices with terrestrial information centre vitality prices. Information 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 yr.
Google’s paper stated launch prices to low Earth orbit would want to fall to about US$200 per kg. At that stage, the launch value unfold in a spacecraft’s working life might turn out to be roughly comparable with terrestrial information centre vitality prices on a per-kW foundation. The comparability is determined by launch prices falling to that stage, and is unique of any prices of working a knowledge 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 elements uncovered to the radiation of area), thermal design (how you can 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 doable launch supplier for Venture Suncatcher. SpaceX has expertise launching massive satellite tv for pc constellations via Starlink and operates reusable rockets which can 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 complete 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 revealed nor funds dedicated.
Google’s deliberate prototype with Planet Labs is the following said step for Venture Suncatcher. Planet Labs already operates Earth-imaging satellites and is Google’s companion for the primary take a look at part.
