    TOXICMAN: Ted jsem cetl ze starlink sice delal upravy aby se snizil odraz, ale pozdeji se na to vykaslal, tak nevim jak to je. Nejaka nezavisla mereni magnitudy nekde?:

    "These satellites, like several hundred before it, are version 1.5 of the Starlink design. Those satellites lack visors that SpaceX installed on satellites in 2020 to keep sunlight from reaching reflective surfaces on the satellites and thus reduce their brightness as seen from the ground. The visors were not compatible with the laser intersatellite links installed on the V1.5 satellites.

    Astronomers say they’ve noticed the V1.5 satellites are brighter than the earlier “VisorSat” Starlink satellites."

    @Starlink
    The Starlink team continues to share best practices for brightness mitigation, and has made the dielectric mirror film available at cost to other satellite operators → https://api.starlink.com/public-files/BrightnessMitigationBestPracticesSatelliteOperators.pdf

    TOXICMAN: @Starlink
    Developed in-house, the dielectric mirrors on the surface of the satellites and extremely dark black paint for angled surfaces or those not conducive to mirror adhesion help absorb and redirect light away from the ground

    We firmly believe in the importance of protecting the night sky for all to enjoy, which is why the Starlink team has been working with leading astronomers around the world to reduce satellite brightness

    E2E4: Mame starlink v praci, zapadni pobrezi US, misto kde neni signal a je to skoro jak pevna linka, na beznym surfovani/stahovani to clovek nepozna (videl jsem i lehce pres 200Mbps), jediny kde jo, tak jsou online hry, kde ma clovek krapet vyssi ping (na mistni servery kolem 50ms), ale na druhou stranu pres Starlink jdou hrat WoT na evropskym serveru (~150 - 200ms lag), kdezto doma na pevny to hrat nejde (500+ ms lag)

    JARDABEREZA: jo freonu bylo dost

    cca pred peti roky: estimates are that rocket launches around the world inject 10 gigagrams, or 11,000 tons, of soot and alumina particles into the atmosphere each year

    a pak tady nejaka cerstvejsi celkem pekna studie, kdyby sis chtel pocist: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021EF002612

    s tim jak pocet startu a vynesenyho nakladu rapidne roste, urcite bude zajimavy tohle sledovat

    SPLNYX: Koukám na to. Zatím popisují obavy z neznáma... což je určitě dobré vzít v potaz. Ale neznají nebezpečné množství ani jsem neviděl, jak dlouho čekají, že se to v atmosféře udrží. Mimo jiné uvádí: "Boley said that as the alumina sinks into the stratosphere, it will cause chemical reactions, which, based on existing knowledge, will likely trigger ozone destruction.

    Drolshagen, who wasn't involved in the recent study, agreed that because "satellites are mostly made of aluminum, the amount of aluminum deposited in the atmosphere will certainly increase."

    Není mi z toho úplně jasné jak by vypadal ten chemický process, který by ozon ohrožoval... co se s čím spojí.

    DZODZO: To bohužel vytváří nový problém s přehříváním satelitu na přímém slunci. Musí najít nějaký kompromis mezi odrážením a přehříváním.


    PER2: Jestli to čtu dobře tak 400 000t freonu ročně byl fakt problém. Ale u každé chemikálie to bude jiné, podle jejich reakcí. https://www.pnas.org/doi/10.1073/pnas.1417372111
