Summary

Google Launches TPU Satellite

Google launched MVP satellite with four Tensor Processing Units on a SpaceX Falcon 9 rideshare from Vandenberg.
Satellite will run Gemini on TPUs in 15-minute bursts for a year.
It is powered by a 1-kilowatt solar array generating up to eight times Earth’s output.
UC Davis tests exposed the TPUs to five-year space doses with no failure.
Experts say heat removal, radiation, bandwidth and launch cost limit scaling data centers.

Summary

Google Tests Suncatcher

Google partnered with Planet Labs to build the Project Suncatcher prototype satellite.
The mission’s research team published a peer-reviewed paper in the journal Joule.
Senior director Travis Beals said the launch serves as an early technology-validation step.
Alphabet’s equity stake in SpaceX is valued at more than $82 billion.
Analysts say the test, aimed at informing future designs, is not a near-term revenue catalyst and will assess orbital scalability.
