- Google launched Suncatcher earlier this month aboard a SpaceX Falcon 9 with more than 100 other spacecraft; after about three weeks of commissioning, the prototype is online, communicating with the ground and operating nominally.
- Suncatcher carries four Google TPUs and can generate up to 1 kW, but the power budget allows only one TPU to operate at a time for roughly 20 minutes, complicating space-to-ground communications.
- Gemma 4 was preloaded on Suncatcher for its first ground prompt, which asked the model to write a space-themed haiku; the satellite was also tasked with reporting orbital conditions.
- TPU chips aboard Suncatcher are undergoing thermal-stress and radiation testing because radiation-induced bit flips can corrupt stored data without triggering standard monitoring tools; ground testing suggested inference would be less affected than training.
- Suncatcher’s next step, contingent on the chips proving capable, is two more satellites in 2027 with greater power generation and inter-satellite optical links for distributed workloads.
- SpaceX would need to fly Starship 1,800 times, according to a peer-reviewed Suncatcher analysis, to match learning-driven cost reductions from its earlier vehicles; both Google and SpaceX’s orbital-data-center plans require fully and rapidly reusable Starship.
- Suncatcher is largely alone among space-data-center concepts in planning high-speed links between satellites: Starcloud and Cowboy Space expect to perform inference on individual satellites, while SpaceX’s envisioned laser-linked satellites would orbit too far apart to share processing effectively.
Why it matters: Google’s planned 2027 follow-on of two satellites is conditional on the TPUs proving capable, but the 1 kW system currently permits only one chip to run for about 20 minutes. This makes the project a concrete test of whether orbital inference can survive radiation and power limits well enough to support a networked satellite architecture.
