Industry Odisha Bureau, Sept 25: In latest news, Google is preparing to send its Tensor Processing Units (TPUs) into low Earth orbit. This comes as part of an experiment to explore whether space could support future AI computing infrastructure.
The project goes by the name of ‘Project Suncatcher.’ It will begin with a prototype satellite carrying Google’s AI hardware. The satellite is scheduled to fly on SpaceX’s Transporter-18 rideshare mission in partnership with Planet Labs. The test will examine whether TPUs can operate in the harsh conditions of space, including radiation, extreme temperatures and launch-related forces.
Google said the first mission is an early experiment and does not represent the launch of an operational data centre in orbit.
Elon Musk reacted to Google’s plans on X. He said that computing capacity in space could eventually account for almost all computing resources. Musk has previously argued that space-based AI could help meet the growing energy needs of artificial intelligence.
Google is also examining the challenges involved in operating computing hardware in orbit. During launch, spacecraft can experience intense vibration and acceleration. Radiation from cosmic rays and solar activity can also disrupt electronic components.
The company said tests of its Trillium TPUs at UC Davis’ Crocker Nuclear Laboratory showed that the chips could withstand radiation levels above those expected during a five year space mission. However, Google plans to collect real-world data through the orbital test.
Cooling is another challenge because there is no normal airflow in space. Google is testing heat pipes and radiators to remove heat from the TPUs. Eventually, the company plans to test two satellites in orbit in 2027, using laser links to connect them. Future designs could involve satellite clusters carrying dozens of TPUs and working together on larger AI workloads.
