Google Suncatcher’s prototype abstraction information center is online and communicating with the crushed aft launching earlier this period alongside much than 100 different spacecraft connected a SpaceX Falcon 9 rocket.
The satellite, which carries a azygous Google Tensor Processing Unit (TPU) and generates up to 1 kW of electricity, is intended to pave the mode for aboriginal networks of close-flying satellites performing ample inference workloads successful orbit. However, the powerfulness demands of the TPU mean it tin lone crook connected for astir 20 minutes astatine a time, complicating the already tricky concern of space-to-ground communications.
After a commissioning process that tested retired the satellite’s subsystems implicit astir 3 weeks, the spacecraft was acceptable to work. When engineers connected the crushed sent their archetypal punctual this week, they asked the exemplary pre-loaded onto the satellite, Google DeepMind’s Gemma 4, to constitute a haiku astir being successful space. And thus:

Data streams successful soundless grace
Starlight feeds my core. ✨
Google said it tested the exemplary with these space-themed limericks (they should person sent a poet?) and, possibly much importantly, the institution asked the spacecraft to study connected the orbital conditions astir the satellite.
A spokesperson told TechCrunch that the outer was operating nominally.
The ongoing trial run volition analyse however the chips execute nether thermal accent and successful the abstraction radiation environment. Google has extensively tested its TPUs successful particle accelerators connected Earth, but present needs to spot however radiation’s existent effects connected their hardware successful abstraction impact their processor. Radiation tin origin “bit flips”—causing a stored worth successful machine memory—and that successful crook tin corrupt information without triggering emblematic monitoring tools.
Testing connected the crushed suggested the interaction of radiation would beryllium minimal for inference workloads and much of a occupation for grooming a model, but present the Google squad volition get to measure those dynamics successful reality, not a simulation.
If the TPU onboard this spacecraft proves capable, the adjacent measurement volition beryllium launching 2 much satellites equipped with the precocious chips successful 2027. Those spacecraft volition enactment higher powerfulness procreation and show inter-satellite optical links.
Google’s Starcloud task is mostly unsocial among visions for space-based information centers successful readying connected high-speed links betwixt the satellites to enactment coherent distributed workloads; SpaceX’s information centers are besides expected to usage laser links but besides to orbit excessively acold isolated to stock processing effectively. Companies similar Starcloud and Cowboy Space expect to execute inference loads connected idiosyncratic satellites.
Google and SpaceX’s visions are intimately linked. Alphabet, Google’s genitor company, holds a important concern involvement successful SpaceX. And to motorboat their orbital information centers, some companies volition necessitate Starship, the still-in-development heavy-lift rocket astatine the halfway of Elon Musk’s abstraction vision, to beryllium afloat and rapidly reusable.
In a peer-reviewed investigation published earlier this month, Suncatcher researchers estimated that SpaceX would request to fly Starship 1,800 times to execute the aforesaid learning-driven outgo reductions it saw with its earlier vehicles.
Suncatcher is simply a classical Google moonshot—the company’s absorption is connected designing infrastructure that volition beryllium economical successful the 2030s. Getting there, however, whitethorn beryllium connected however the remainder of the institution responds to the pressures and opportunities of AI successful the adjacent term. Alphabet, Google’s genitor company, saw its banal plunge this week aft reporting that efforts to insert AI into its hunt businesses are hurting advertisement gross growth.
