SpaceX and Google Launch AI Chips to Test Space-Based Data Centers
On Thursday, SpaceX is set to launch Alphabet's custom-built tensor processing units (TPUs) aboard Planet Labs satellites as part of the Transporter-18 mission. This marks the first in-orbit test for Alphabet’s Project Suncatcher, an initiative aimed at developing solar-powered AI computing infrastructure in space. The project seeks to leverage near-constant sunlight and vast orbital 'real estate' to create scalable machine learning systems beyond Earth's data centers. Alphabet holds a significant $82 billion stake in SpaceX following its record-breaking IPO earlier this year. While the two companies are close partners, they also compete within AI development. The mission is part of broader efforts by both firms to explore orbital computing solutions—SpaceX plans to build and launch its own data centers using satellites equipped with GPUs and solar arrays. Experts remain skeptical about the feasibility due to high costs, technical challenges like radiation resistance, cooling systems for extreme temperatures, and space debris. Despite these hurdles, SpaceX COO Gwynne Shotwell has stated that orbital supercomputing could be deployed by 2027.
