    Reflect Orbital and SpaceX have filed proposals with the US Federal Communications Commission that threaten ground-based astronomy. We submitted replies and collaborated with the UK Royal Astronomical Society & the International Astronomical Union for their responses. 1/

      Space-X applied to launch one million satellites to act as data centres. Brightness estimates show that thousands would be visible to the naked eye, many more than visible stars. On average, each image with our Very Large Telescope would lose 10% of data due to satellite trails. 2/

        Reflect Orbital plans to use a constellation of space mirrors to reflect sunlight to Earth at night. Each beam would be four times brighter than the full Moon and would also contaminate areas outside the beam. Their planned 50,000 mirrors would make the night sky three to four times brighter. 3/

          Besides the obvious impact on astronomical observations, damaging the night sky threatens to collapse nocturnal ecosystems and will impact humans too. We support submissions to the FCC by other astronomical organisations, and we will follow up the eventual responses from SpaceX and Reflect Orbital. 4/4

            That's insane!
            I hope that the application will be denied "for the good of all of humanity"!
