In the request, David Goldman, SpaceX's director of satellite policy, said the expansion "would serve the public interest" and "allow operators and passengers to access services that enable increased productivity."

Musk also tweeted Friday that Starlink's "service uptime, bandwidth & latency are improving rapidly." In February, Musk promised that Starlink internet speeds would double and latency would drop by the end of 2021. Insider previously reported that Starlink subscribers were getting faster internet than SpaceX said they should expect.

Even in freezing temperatures, high winds, and snow, Starlink has hit speeds of 175 Mbps, users told Insider.  

SpaceX has already launched 1,300 Starlink satellites into orbit, and eventually wants up to 42,000 enveloping the Earth.
