Print While the FCC evaluates the potential harms of satellite constellations, it currently exempts almost all telecommunications projects — including satellites — from facing formal environmental reviews. Currently there’s limited international cooperation in the regulation of satellite constellations. More than 100 space researchers signed a letter urging the federal government to perform an environmental review before allowing SpaceX to continue launching thousands of satellites for its internet service, Starlink. The Federal Communications Commission has licensed Elon Musk’s company to launch nearly 12,000 satellites into space — more than double the number of non-SpaceX satellites orbiting Earth. SpaceX is asking the FCC to allow it to launch over 20,000 more. While the FCC evaluates the potential harms of satellite constellations, it currently exempts almost all telecommunications projects — including satellites — from facing formal environmental reviews. The researchers’ letter, released on Thursday, argues that much has changed since the rule was created almost four decades ago.

Now it’s happening NASA JPL’s Europa Clipper spacecraft, the largest planetary probe ever built, will launch as early as Friday to explore Jupiter’s icy ocean moon. Oct. 9, 2024 Gutterman said PIRG has heard back from the FCC and is excited to meet with the agency to discuss the group’s concerns. The Starlink constellation provides internet coverage across the globe, especially to rural communities and countries without reliable cell tower service. The service has provided internet access to Ukrainian soldiers, hurricane victims and commercial flight passengers. Advertisement SpaceX’s satellites are designed to have a roughly five-year lifespan, after which SpaceX ground controllers will deorbit the satellites, let them burn up in Earth’s atmosphere and launch replacements. This injection of metals and other compounds into the upper atmosphere from the incineration of the spent satellites has the potential to disturb the delicate balance of elements and molecules in the air, the letter argues. “The industry has moved faster than regulators can act and faster than the public has really been aware,” Gutterman said. “The results aren’t in — we just don’t actually have the data on what effects this new technology could have.” In a 2022 report, the Government Accountability Office — a nonpartisan federal agency tasked with saving taxpayer money and increasing government efficiency — recommended the FCC review whether the satellite constellations normally have significant environmental impacts. The FCC agreed with the findings.

As satellites whiz past the field of view of telescopes, they leave streaks in astronomers’ images. To compensate, scientists have had to frequently retake images and develop more sophisticated computer programs to remove the streaks. “Picture an open book. Then picture a big marker streak across the page,” said David Jewitt, a distinguished professor of astronomy at UCLA who signed the letter. “That’s what they do.”
