Neue ESO-Studie bewertet den Einfluss von Satellitenkonstellationen auf astronomische Beobachtungen
Die Studie kommt zu dem Ergebnis, dass große Teleskope wie das Very Large Telescope (VLT) der ESO und das kommende Extremely Large Telescope (ELT) der ESO von den in der Entwicklung befindlichen Konstellationen “mäßig beeinflusst” werden. Der Effekt ist bei Langzeitbelichtungen (von etwa 1000 s) stärker ausgeprägt, von denen bis zu 3% in der Dämmerung, der Zeit zwischen Morgengrauen und Sonnenaufgang und zwischen Sonnenuntergang und…

The head of NASA’s human exploration program said today that the lunar Gateway that has been a linchpin of the Artemis program no longer is a mandatory component of getting astronauts back on the Moon by 2024. NASA has decided to “decouple” getting to the Moon “fast” versus getting there “sustainably” and Gateway is not needed to get there fast. This dramatic turnaround was driven by the need to meet the Trump Administration’s deadline to put astronauts on the lunar surface before the end of a second Trump term if he is reelected.”
