00:09Google is heading to the stars.
00:12The tech giant just announced plans to launch its first test of AI chips in space, known
00:18as Project Suncatcher.
00:20Project Suncatcher is a research effort aiming to explore if space can actually host large-scale
00:27AI computing infrastructure, potentially bypassing terrestrial energy constraints.
00:32I think everyone's reaction almost when you hear this idea is, that's crazy, there must
00:36be a reason it won't work.
00:38And so the first thing we tried to do is to find that reason.
00:41It turns out that it is possible.
00:45At the heart of it, Project Suncatcher is a simple idea.
00:49How can we efficiently scale AI infrastructure through orbital data centers by leveraging
00:54the abundant energy that we can get from the sun?
00:57The mission is set to fly on SpaceX's Transporter 18 rideshare launch, partnering with satellite
01:03company Planet Labs to get this technology into orbit.
01:07At the core of this mission are Google Tensor Processing Units, the same hardware behind much
01:13of their advanced AI work here on Earth.
01:15The satellites will head to Low Earth Orbit, or LEO, to see how these chips handle the harsh
01:21conditions of spaceflight and operation.
01:24Engineers need to know how the hardware survives launch forces, extreme temperatures, and intense
01:31space radiation, which often causes data errors like bit flips.
01:35Before reaching orbit, Google tested these TPUs running AI workloads extensively at a specialized
01:42facility at the University of California, Davis.
01:45Because conventional airflow cooling doesn't work in a vacuum, the team is testing a unique
01:51cooling design using a combination of heat pipes and radiators.
01:55This first mission is strictly for gathering in-orbit data and identifying potential failure points,
02:02rather than attempting to launch a full-scale orbital data center.
02:06Looking ahead, Google plans to launch two more satellites in 2027 to test high-bandwidth laser
02:13links, essential for connecting future computing clusters.
02:16Despite the ambition, experts note this concept remains years from commercial viability due to
02:23high launch costs, satellite production bottlenecks, and engineering constraints.
02:28Google's foray into space computing marks a bold step, but only time and testing will tell
02:34if AI data centers belong among the stars.
