Environmental groups want America's FCC "to slam the brakes on orbital datacenters," writes The Register. They're arguing for an environmental impact assessment for what could be 1 million satellites:Earthjustice, acting on behalf of DarkSky International, Environment America, and Public Employees for Environmental Responsibility (PEER), filed a petition this week... The filing doesn't target any single company. Instead, it asks the regulator to put the entire emerging orbital datacenter sector on hold while it assesses the cumulative effects of proposals from SpaceX, Starcloud, Blue Origin, Cowboy Space, and any similar applications that follow. According to the petition, those proposals collectively seek "well over a million datacenter satellites" in low Earth orbit.... " increasing the existing volume of satellites in low-earth orbit by multiple orders of magnitude." The groups argue that the FCC is trying to apply licensing rules written for much smaller satellite constellations to an entirely new class of infrastructure. "If ever a situation warranted a Programmatic Environmental Impact Statement [PEIS], it is this one," the petition says. It argues that a single review would allow the agency to examine "the risks, alternatives, needs, costs, and impacts of this sudden transformation of Earth's exosphere" before deciding whether any of the projects are in the public interest. The petition raises concerns about rocket launch emissions, pollutants released as satellites burn up during atmospheric reentry, depletion of the ozone layer, orbital debris, light pollution, impacts on wildlife, and interference with astronomy. It also argues that the combined effects of these constellations cannot be understood by evaluating applications one at a time.... "It is difficult to imagine a better example of multiple projects presenting essentially identical impacts and risks that compound synergistically and cumulatively than the present proposals..." The petition argues that the FCC's current approach, which generally treats satellite licenses as categorically excluded from detailed environmental review, is no longer fit for proposals measured not in dozens or thousands of spacecraft but in hundreds of thousands and, potentially, millions. If the FCC agrees, orbital datacenter operators will have a mountain of paperwork to clear before sending their hardware skyward.Read more of this story at Slashdot.
