Space Bugs: Astronomers Raise Objections to Google’s AI Constellations

Google’s ambitious “Project Suncatcher” may promise a cleaner future for AI, but for the astronomy community, it represents a growing nightmare. The plan for constellations of 80 satellites adds to a problem that astronomers warn is “like bugs on a windshield,” obscuring our view of the cosmos.
Scientists are increasingly concerned that the rising number of satellites in low orbit is hampering vital research. These objects, including Google’s proposed AI datacenters, reflect sunlight and create bright streaks across telescope images, ruining observations and polluting the night sky.
This objection creates a significant public relations and regulatory hurdle for Google, which is trying to frame its space plan as an environmental positive. The company’s goal is to minimize the land and water impact of AI, but in doing so, it may be maximizing the visual and scientific impact on the sky.
The plan also faces a second environmental critique: the launch emissions. While the satellites would run on clean solar power, each rocket launch to deploy them emits “hundreds of tonnes of CO2.” This upfront carbon cost complicates the “green” narrative.
As Google moves toward its 2027 prototype launch, it will have to navigate this “ground-versus-sky” environmental conflict. The company must balance the clear benefits of 8-times-more-efficient solar power against the objections of astronomers and the undeniable carbon cost of every single launch.
