"Niebo gwieździste nade mną - prawo moralne we mnie", mawiał wielki filozof z Królewca.
Niestety nieba gwiaździstego nad naszymi głowami coraz mniej z powodu light pollution, a nad moralnością takich delikwentów jak Elon Musk lepiej spuścić zasłonę milczenia. Wskazałem akurat na tego typa, bo to on jest w dużym stopniu odpowiedzialny za "zaświnianie" nieba coraz większą ilością minisatelitów, generujących zanieczyszczenie wizualne. Problem ów ma dwa wymiary. Pierwszy jest kulturowy, bo prawo do nieba gwiaździstego nad głową każdego człowieka jest prawem...naturalnym. Drugi jest zdecydowanie bardziej konkretny, bo dotyczy badań Kosmosu prowadzonych przez rozliczne obserwatoria astronomiczne, dla których rozświetlające nieboskłon gadżety Muska stają się coraz poważniejszym problemem. Jest jeszcze rzecz jasna problem zaśmiecania Kosmosu żelastwem satelitarnym oraz kolizji do jakich może dochodzić w coraz bardziej gęstniejącym "ruchu satelitarnym" wokół naszej planety - ale to temat na tyle obszerny ze warty odrębnego wątku.

"The natural serenity of the night sky is a touchstone for all of us. Everyone alive today looks at the same stars no matter where they are located on the planet. But the connection is more profound because, next to our brief lives, the stars are immortal. Shakespeare saw the same stars in the same patterns that we do. So did Galileo, Columbus, Joan of Arc, Cleopatra and the first human ancestor to look up in curiosity. The night sky is nothing short of our common human heritage.Since that time, SpaceX has launched hundreds more Starlink satellites, and although watching these satellites pass overhead has become a new hobby for some, others are worried about the cultural implications, and the way it could affect our relationship with the night sky. Left unchecked, we may never again be able to experience a view of the silent, still cosmos with our own unaided eyes. Instead, it will always be criss-crossed by bright, human-made objects.“In a couple of generations there will be no one left alive who remembers the night sky before these satellites. They will have grown up with Starlink and the other proposed megaconstellations as part of their conception of the night sky. I think that’s a radical change,” says Alice Gorman of Flinders University, South Australia, a pioneer in the emerging field of space archaeology and heritage.“One of the reasons people value the night sky is because it gives you a sense of transcendence and connectedness to the universe, and inspires contemplation about the meaning of life and the massive scale of stars and galaxies. That seems to be an experience that people really value and so people have argued that a right to the night sky is kind of fundamental to being human,” says Gorman."

"But then there are the astronomers. They perhaps stand to lose the most from the megaconstellations as the satellites will forever be crossing their fields of view, damaging their ability to collect data from the distant universe. Take, for example, the Vera C Rubin Observatory, an American-funded facility in Chile. This gigantic telescope has been in development for more than 20 years and costs millions of dollars. It is designed to begin the deepest survey of the night sky ever in 2022, but now its astronomers are wondering how to deal with the plethora of Starlink satellites that will streak across its images every night.Robert Massey, the deputy executive director of the Royal Astronomical Society, has taken a particular interest in the consequences and understands that it is a knotty problem. “I recognise that there are multiple uses of space, and that astronomers are not the only community with a stake in that,” he says. “On the other hand, you can also argue that private companies are not the only organisations that have a stake in the now burgeoning commercialisation of low-Earth orbit. They should be regulated, just as they are on the surface of the Earth and in the atmosphere, the seas and so on.”.
