SpaceX's next generation of Starlink satellites could pose an even greater threat to astronomical observations.
“Bottom line is that they are bigger. This in turn would mean that—everything else being equal—they will be brighter than SL1 [the first generation of Starlink satellites],” Olivier Hainaut, an astronomer at the European Southern Observatory, told Gizmodo in an email.
Hainaut estimates that Starlink 2.0 satellites will be about a full magnitude brighter than their predecessors. “With all the mitigation efforts by Starlink, they had managed to get SL1 close to the magnitude 7 limit most of the time,” Hainaut said. “One magnitude brighter would mean that more of the [second generation] satellites would be problematic, which of course is not nice.
“I hope Starlink keeps the communication lines open, and that they have not forgotten about their commitment towards the astronomical community,” Hainaut said.
