Google has unveiled Project Suncatcher, a research effort to place AI‑focused Tensor Processing Units on solar‑powered satellites, creating data centers in orbit. The company argues that space could offer near‑continuous solar energy, potentially making compute more sustainable. Key hurdles include ultra‑high‑speed inter‑satellite links, tight formation flying, radiation tolerance, and cost competitiveness. Google plans a joint launch with Planet to test prototype hardware by 2027, hoping the approach could become comparable to Earth‑based energy costs by the mid‑2030s. Leia mais →

Google is developing Project Suncatcher, a plan to place AI‑focused data centers on a free‑fall satellite constellation. The design calls for tightly spaced satellites—within a kilometer or even several hundred meters—to maintain power links, a formation tighter than any existing constellation but deemed feasible by Google’s models. To keep costs down, Google intends to reuse Earth‑based hardware, testing its durability by exposing its latest Cloud TPU to intense radiation. Prototype satellites could launch by early 2027, with broader deployment targeted for the mid‑2030s when launch costs may fall dramatically, offering a potential solution to the environmental and community challenges of terrestrial data centers.
