An analysis in
Monthly Notices of the Royal Astronomical Society: Letters concludes the overall brightness of the night sky could increase by more than 10 percent across a large part of the planet.
“Our primary motivation was to estimate the potential contribution to night sky brightness from external sources, such as space objects in Earth’s orbit,” said Miroslav Kocifaj of the Slovak Academy of Sciences and Comenius University in Slovakia, who led the study.

SpaceX plans to give vehicles internet by beaming service from its Starlink satellites, according to new filings.
Elon Musk’s space company wrote in filings to the United States’ Federal Communications Commission that it “seeks authority to deploy and operate these earth stations as VMES throughout the United States and its territories . in the territorial waters of the United States and throughout international waters worldwide, and . on U.S.-registered aircraft operating worldwide and non-U.S.-registered aircraft operating in U.S. airspace”.
The filing goes on to assert that it would serve the public interest by expanding “the range of broadband capabilities available to moving vehicles throughout the United States and to moving vessels and aircraft worldwide”, which it suggests is urgent because of “escalating requirements for speed, capacity, and reliability and ongoing adaptations for usage” with regards to internet use.
