Gemma 4 Running in a Space Data Center? Someone Pulled Up Google's Timeline
The original poster says Gemma 4 is running in a space data center, but key information shows up in the comments: the prototype satellites are not due until early 2027, and radiation testing was done on the ground. Heat dissipation, bit flips, and TID/SEU—these hard problems are more worth looking at than congratulations.
A tweet claims that Google Gemma 4 is already running in a space data center and congratulates the Project Suncatcher team. The accompanying video shows a black background with white text: THEY ARE NOT THE SAME.
The news spread quickly. In the comments, someone directly pointed out the timeline issue. User AI Quanting replied that Gemma 4 is not in orbit yet. In Google's own wording, the next milestone is a learning mission with Planet; two prototype satellites are planned to launch in early 2027, and Trillium's radiation testing was completed on the ground. His conclusion was measured: the results are good, but it is still too early to call it a data center.
That reply brought the discussion back to engineering details. There is no air in space, so TPUs cannot be cooled by fans; heat can only be dissipated by radiation. Some users asked how large a radiator each chip would need. This question is not flashy, but it directly determines whether the system can run long term.
Another question is more fundamental. Orbital radiation can flip bits; how does the inference process handle bit flips? Someone asked for TID and SEU figures—total ionizing dose and single-event upset rate. For readers unfamiliar with space electronics, this can be simply understood as: how long a chip can survive in radiation, and how often it will make errors. The reply also mentioned that in-orbit inference has to make economic sense: the compute has to stay alive long enough that it is more cost-effective than transmitting the raw data back to Earth.
Regarding satellite imagery, one user mentioned a practical benefit: send conclusions back to Earth and transmit fewer raw pixels. This direction sounds reasonable, but the prerequisites remain stable in-orbit computing, sufficient lifespan, and controllable heat dissipation.
There were also lighter comments. Someone said the "local" in local AI has a new meaning, while their own model is still stuck on the Mac mini on their desk. Someone joked that in the future, inference latency will have to account for orbital mechanics and waiting for the satellite to come out from behind the Earth.
