SpaceX Transporter-18 carries Google’s first in-orbit TPU test
On Oct. 1, 2026, SpaceX’s Falcon 9 Transporter-18 rideshare from Vandenberg is scheduled to loft Planet Labs’ Project Suncatcher M1 prototype with Google TPUs, the first flight test for Alphabet’s orbital AI compute moonshot.
Why it matters: Transporter-18 puts Google’s first TPU pathfinder on a SpaceX rideshare, a real flight step toward orbital AI compute.

SpaceX is targeting Thursday, Oct. 1, 2026, for Falcon 9’s Transporter-18 rideshare from Space Launch Complex 4E at Vandenberg Space Force Base, with a 58-minute window opening at 11:18 a.m. PT. Among 130 payloads, the manifest lists Project Suncatcher M1, manifested by Planet Labs, for deployment about an hour after liftoff, according to the SpaceX mission page.
Google says the prototype is the first in-orbit test for Project Suncatcher, a research moonshot on whether low Earth orbit can host scalable machine learning infrastructure. The satellite, built with Planet, carries Google Tensor Processing Units so the team can gather data on launch stress, radiation, and thermal extremes. Google’s Project Suncatcher post notes near-constant sunlight in LEO can yield up to eight times more solar power than on Earth, and that a 2027 follow-on aims to test high-bandwidth laser links between satellites. CNBC reported the same Thursday window and framed the flight as Alphabet’s first spaceborne TPU trial.
Key facts
- Launch target: Thursday, Oct. 1, 2026; window opens 11:18 a.m. PT from Vandenberg SLC-4E; backup Friday, Oct. 2 (SpaceX).
- Transporter-18 carries 130 payloads on a dedicated smallsat rideshare (SpaceX).
- Project Suncatcher M1 is on the deployment list, manifested by Planet Labs (SpaceX, Google).
- Goal of this flight: measure how Google TPUs handle launch loads, radiation, and thermal conditions in LEO (Google, CNBC).
- Ground tests already included vibration and proton-beam runs at UC Davis; Google says Trillium TPUs survived a total ionizing dose above a five-year mission estimate (Google).
- Next stated milestone: two satellites in 2027 to exercise short-range, high-bandwidth laser links (Google).
How to read it
This is a pathfinder flight, not a full orbital data center. Success means useful telemetry on chips and cooling in vacuum, not commercial AI capacity on day one. SpaceX has separately talked about its own orbital supercompute plans; this payload is Google’s hardware on a Planet-built bird riding SpaceX’s rideshare.
