Starlink Satelitten... was wird denn jetzt?

SpaceX hat letzte Woche vom FCC Lizenzen für 30000 weitere Satelliten bekommen, die im LEO stationiert werden sollen. Damit wächst die Flotte von 12000 auf 42000.

Zur Starlink-Problematik gibts noch einige weitere interessante Artikel, die in den letzten Tagen erschienen sind. Offenbar ist das Problem für die professionelle Astronomie und für die Raumfahrtexperten nach wie vor relevant!

Für die fotografische Detektion von Meteorschauern wird es in Zukunft, Dank der Starlink Satelliten, schwierig werden. Hier ein "schönes" Belegvideo aus La Palma, das während des Peaks der Alpha Monocerotiden am Morgen des 22. November 2019 aufgenommen wurde. Dabei wurden die einzelnen Himmelsaufnahmen addiert.

Spaceweather.com schreibt folgendes:

As predicted by forecasters Esko Lyytinen and Peter Jenniskens (NASA/Ames), Earth grazed a filament of comet dust, prompting a modest flurry of meteors to emerge from the constellation Monoceros (the Unicorn). In La Palma on the Canary islands, a Global Meteor Network camera captured the display--and something more. Starlink photobombed the meteor shower:

Dozens of Starlink satellites flew through the camera's field of view, putting on a display that rivaled the meteor shower itself. The score: alpha Monocerotids 90, Starlink 50. And the Starlink satellites were much brighter.

"It was a real eye-opener," remarked Bill Cooke, the lead of NASA's Meteoroid Environment Office, when he saw the video. "This kind of thing could force us to change how we write software to auto-detect meteors."

Starlink is a venture by SpaceX. The idea is to launch 12,000 or more satellites into Earth orbit, surrounding our planet and providing global internet coverage even to people in remote areas. The first batch of 60 Starlink satellites launched in May 2019 surprised astronomers and prompted the International Astronomical Union to issue a statement of concern. Filling the sky with artificial stars might not be good for astronomy, they suggested.

The satellites that flew over La Palma during the alpha Monocerotid shower on Nov. 22nd came from a 2nd batch of 60 launched on Nov. 11, 2019. To be fair to Starlink, the train did not stop the camera from successfully recording the shower as shown in the histogram above. However, sharing the sky could become more challenging in the years ahead as Starlink expands from dozens to potentially thousands of satellites.
