...also 5 Satelliten reichen wohl nicht. Aber selbst falls sie eine globale Abdeckung anstreben würden, bräuchten #BlueWalker dafür anscheinend um Größenordnungen weniger Satelliten als #Starlink.

P.S.: Ich finde Lichtverschmutzung *nicht* gut.
Ein weiterer Beleg dafür, warum #Außerirdische uns nicht besuchen:
Genau das braucht die Menschheit: Noch mehr #Lichtverschmutzung. Weil das ja so gut ist.
"Der erste von 100: Riesensatellit #BlueWalker 3 heller als fast alle #Sterne
#ASTSpaceMobile will mit riesigen #Satelliten Smartphones online bringen. Nun bestätigt eine ausführliche Analyse die Befürchtungen in der #Astronomie."
Proud to be co-author to this just published paper in #Nature, about the high brightness of the prototype satellite, #BlueWalker 3, for a future 243-satellite satellite constellation:

Several hundred of magnitude zero satellites in the sky will not only alter the outlook of the sky, but also means astronomical observatories will have to do active mitigation. We call for more attention to such unwanted side-effects as part of launch permit assessments.

#Bluewalker 3 #satellite is brighter than 99.8 per cent of visible stars
Observations of a huge test satellite that launched in September have fuelled concerns about the impact a planned fleet could have on #astronomy
The 64 square metre reflective array of the Blue Walker 3 satellite for a future space-to-Earth mobile phone network is brighter than 99.8 per cent of stars visible to the naked eye. If a planned fleet of 100 additional satellites is as bright or brighter, astronomers are concerned it could severely impact ground-based astronomy
