Our Project Suncatcher prototype satellite is in orbit.
Google’s Project Suncatcher prototype satellite, developed with Planet, launched aboard SpaceX’s Transporter-18 mission to test machine learning hardware in space.
Google announced the successful deployment of its Project Suncatcher prototype satellite, launched aboard SpaceX’s Transporter-18 rideshare mission. The satellite was built in collaboration with Planet and has entered orbit as planned. Initial contact has been confirmed, and the satellite is functioning as expected, marking the first phase of a broader research initiative.
The mission aims to assess whether space could support scalable machine learning infrastructure in the future. Over the coming weeks, Google will collect data on how its Tensor Processing Units perform under spaceflight conditions, including radiation exposure and extreme thermal variations. These findings will guide further design refinements for potential long-term applications.
A peer-reviewed paper detailing the research behind Project Suncatcher has been published in the journal Joule. The paper outlines the scientific and engineering challenges addressed in preparing the satellite for space. Researchers emphasize that certain conditions required for testing can only be replicated in an orbital environment.
Google plans to share updates as the mission progresses, including insights gained from the satellite’s performance. The team will use the data to improve hardware resilience and explore opportunities for future scalable infrastructure in space. Further announcements are expected as experiments continue.
