Google’s “Project Suncatcher” highlights a profound, modern dilemma: the rocket. This one technology is simultaneously the key to a sustainable future and a source of significant pollution.
On the one hand, the “falling cost of rocket launches” is what makes Google’s plan for orbital, solar-powered AI datacenters viable. The rocket is the only way to access the “unlimited, low-cost renewable energy” of space, which (as Starcloud claims) could lead to a “10 times carbon dioxide savings” over the datacentre’s life.
On the other hand, the article explicitly states that “launching a single rocket into space emits hundreds of tonnes of CO2.” This makes the very tool for achieving a low-carbon future a high-carbon emitter.
This paradox is at the center of the plan. To build its 80-satellite constellations, Google will need many of these high-emission launches. This upfront environmental cost must be “paid” to unlock the long-term, zero-emission operational benefits.
This is a high-stakes environmental gamble. Google is betting that the long-term benefit of 8x-more-efficient solar power will far outweigh the short-term CO2 emissions. But for now, every “clean” AI datacentre launched into orbit will begin its life with a significant carbon footprint.
