WASHINGTON 鈥 The National Aeronautics and Space Administration (NASA) raised concerns about SpaceX鈥檚 plan to deploy about 30,000 satellites for its Starlink, as have some major companies.聽

Elon Musk鈥檚 SpaceX previously received authorization for about 12,000 satellites to offer broadband internet and has requested authorization for a second-generation constellation of聽 30,000 satellites.聽

鈥淣ASA has concerns with the potential for a significant increase in the frequency of conjunction events and possible impacts to NASA鈥檚 science and human spaceflight missions,鈥 the agency wrote the Federal Communications Commission.聽

NASA noted there are currently 25,000 total objects tracked on-orbit 鈥 and about 6,100 below 600 km. SpaceX鈥檚 Gen2 expansion 鈥渨ould more than double the number of tracked objects in orbit and increase the number of objects below 600 km over five-fold,鈥 it added.聽

Harvard-Smithsonian astrophysicist Jonathan McDowell, part of the American Astronomical Society panel examining the impacts of satellites on astronomy said: 鈥淲e鈥檝e been concerned with having these large numbers of satellites that interfere with astronomical observations … I think we need a little more experience with the several thousand operating satellites before we can ramp up to the tens of thousands.鈥澛

SpaceX did not immediately respond to a request for comment.聽

Mr. Musk tweeted on Jan. 15 SpaceX had 1,469 Starlink satellites active and 272 moving to operational orbits soon.聽

Amazon.com, which has pledged to spend at least $10 billion to build 3,236 such satellites through its Project Kuiper program, separately raised concerns with the FCC about SpaceX鈥檚 plan as did Dish Network.聽

Amazon said under SpaceX鈥檚 application 鈥渁t least hundreds 鈥 and potentially more than ten thousand 鈥 SpaceX satellites could operate at the same altitudes as the Kuiper System.鈥澛

It warned 鈥渢he effect of this orbital overlap would be a dramatic increase in risks and other burdens on the Kuiper System鈥 and asked the FCC to impose 鈥渞easonable conditions.鈥澛

While extremely costly to deploy, satellite technology can provide high-speed internet for people who live in rural or hard-to-serve places where fiber optic cables and cell towers do not reach. The technology could also be a critical backstop when hurricanes or other natural disasters disrupt communication. 鈥 David Shepardson and Steve Gorman/Reuters
