Google detailed progress on Project Suncatcher, its moonshot to run ML infrastructure in space: a prototype satellite with TPUs launches on SpaceX's Transporter-18 rideshare (with partner Planet) after ground tests showed TPU survival beyond a five-year equivalent radiation dose, with vibration and thermal-vacuum cooling tests underway. Two satellites follow in 2027 to test high-bandwidth laser links between orbital compute nodes.

Why it matters

First hardware milestone toward satellite-based AI scale-out, positioning compute-in-space as a long-term alternative to terrestrial datacenter buildout.

Importance: 3/5
