🛰️ 1 to 2 Starlink satellites are falling back to Earth each day

｢ Many of these are in low-Earth orbits, which extend up to an altitude of 1,200 miles (2,000 km) above our planet. And the lifespan of low-Earth orbit satellites, such as Starlink, is only about 5 to 7 years. Soon, McDowell told us, there will be up to 5 satellite reentries per day ｣

Ob sich die Internetanbieter via #Satelliten Gedanken um unsere #Atmosphäre machen?

Die aktuell mehr als 10.000 Satelliten, welche sich dafür in einem erdnahen Orbit bewegen, sind auf Verschleiß konzipiert. Das heißt sie haben nur eine begrenzte Lebensdauer und werden nach Ablauf dieser ersetzt. Jedes Jahr werden deshalb hunderte dieser Satelliten in der Erdatmosphäre verglühen. Sie bestehen aus seltenen Metallegierungen und viel Aluminium (ein eher reaktionsfreudiges Element). Die Anbieter wollen mit noch mehr Satelliten ihre Abdeckung verbessern, geplant seien mehr als 40.000 Satelliten im Orbit.
Untersuchungen, was die in die Atmosphäre eingebrachten Stoffe bewirken, scheint es bisher kaum zu geben. Immerhin gibt es erste Artikel, die am Rande auf das Problem eingehen.
(Die genannten Zahlen basieren auf Wikipedia -Einträgen zu #Starlink, #Kuiper & #OneWeb von #Musk, #Amazon & #Eutelsat )

So, I was talking with my supervisor about how #Starlink is trying to divert money intended for #FiberOptic, and told her about the #KesslerEffect (which will probably be caused by old Starlink satellites).
"I guess that will knock us back to landlines," was her reply.
"All the more reason to have fiber in place!" I chimed in!

Starlink tries to block Virginia’s plan to bring fiber Internet to residents

Starlink operator SpaceX is fighting Virginia's plan to deploy fiber Internet service to residents, claiming that federal grant money should be given to Starlink instead. SpaceX is already in line to win over $3 million in grant money in the state but is seeking $60 million.

Starlink satellite emissions interfere with #radio #astronomy.

The largest-ever survey of low-frequency radio emissions from satellites has detected emissions from the #Starlink satellite “mega-constellation” across scientifically important low-frequency bands, including some that are protected for radio astronomy by international regulations.

These emissions, which come from onboard electronics and are not intentional transmissions, could mask the weak radio-wave signals that astronomers seek to detect.

As well as being damaging for radio astronomy, the researchers who conducted the survey say their findings highlight the need for new regulations that cover unintended transmissions, not just deliberate ones.

I satelliti stanno silenziando l'universo: oltre 112.000 emissioni radio provenienti da 1.806 satelliti Starlink, con fino al 30% di alcuni set di dati che mostravano interferenze

Immaginate di dover ascoltare una conversazione sussurrata mentre vi trovate accanto a un cantiere edile. È essenzialmente ciò che i radioastronomi si trovano ad affrontare oggi, mentre migliaia di satelliti Internet invadono l'orbita terrestre, disturbando accidentalmente i deboli segnali utilizzati per svelare i segreti dell'universo. Uno studio rivoluzionario della Curtin University rivela che la ricerca di connettività globale sta creando un ostacolo inaspettato alle nostre più grandi scoperte scientifiche, dalla comprensione della materia oscura alla verifica delle teorie di Einstein.
