Google's Suncatcher satellite is online this week, carrying the first Google Tensor Processing Units—specialised AI chips—ever flown into space. After commissioning, engineers on the ground sent their first prompt to a pre-loaded Gemma 4 model and asked it to write a haiku about space. The short poem completed successfully, and the craft has also produced orbital reports.
A company spokesperson said the satellite was operating normally. The Google Suncatcher prototype rode a SpaceX Falcon 9 rocket into orbit earlier in October alongside more than 100 other spacecraft. Planet Labs built the satellite that hosts Google's hardware. Roughly three weeks of subsystem checks followed before the craft was ready for its first AI task.
What the satellite can do now
The spacecraft carries four TPUs and can generate up to 1 kW of electricity. Power limits mean only one chip can run at a time, and that chip works for about 20 minutes in each session. Those constraints make already difficult space communications even harder. Even so, the model managed both poetry and orbital reporting from orbit.
The haiku returned to the ground read: "Blue marble below / Data streams in silent grace / Starlight feeds my core."
Why engineers are still testing
The current campaign focuses on two hard problems. First, teams must see how the chips behave under thermal stress in space. Second, they must measure how radiation affects the processors. Radiation can trigger "bit flips"—silent errors that corrupt stored data. Ground tests in particle accelerators pointed to only a small effect on inference, the kind of work used to run a trained model. Real orbit may differ from those simulations. Training workloads, which teach models, face a higher radiation risk than inference. The flight tests are meant to check those predictions in place.
What Google wants next
If the prototype holds up, Google plans two further satellites in 2027. Those craft are expected to generate more power for longer runs and to show optical, laser-style links between satellites. Such links could one day support AI work spread across several spacecraft. The wider Suncatcher idea is a network of satellites flying close together to handle large inference jobs in orbit. That long-term vision leans heavily on SpaceX's Starship rocket.
Timeline: what has happened so far
- Earlier October: Suncatcher launched on a SpaceX Falcon 9 with more than 100 other spacecraft; Planet Labs built the satellite carrying Google's hardware.
- About three weeks after launch: Subsystem testing on the ground and in orbit prepared the craft for AI work.
- This week: The prototype went online; engineers prompted Gemma 4; it wrote a space haiku and produced orbital reports; a spokesperson said operations were normal.
- 2027 (planned): Two more satellites if the prototype succeeds, with higher power, longer sessions, and optical links between craft.
Aasan alfaaz mein
Google ne apna Suncatcher satellite falak mein chala diya hai, jis mein pehli baar Google ke AI chips gaye hain. Is ne pehle kaam mein space ke bare mein ek chhoti English nazm (haiku) likhi. Abhi power kam hone ki wajah se ek waqt mein sirf ek chip, lagbhag 20 minute, chal sakti hai. Agar yeh azmaish theek rahi to 2027 mein do aur satellites aane ka irada hai—aam logon ke bills abhi is se nahi badalte, lekin mustaqbil ke AI services isi tarah ke experiments se shakal le sakte hain.
