NASA lifted problems about SpaceX’s new Starlink satellites, such as an increase of the risk of collision in orbit, in a letter to the Federal Communications Fee (FCC).
The five-web page letter was submitted to the FCC Tuesday (Feb. 8) and was 1st noted in SpaceNews. The letter, which incorporates a separate a person-web page letter from the Countrywide Science Basis, was sent on NASA’s behalf by the Countrywide Telecommunications and Data Administration.
SpaceX submitted a proposal to the FCC to place 30,000 a lot more Starlink internet satellites into orbit as part of a “Gen 2” Starlink method. There are at this time about 1,800 operational Starlink satellites in orbit and there have currently been numerous in close proximity to-misses in orbit 1 research has suggested Starlinks are accountable for 50 percent of all close encounters in low-Earth orbit.
With this observe report, NASA has some severe reservations about SpaceX’s proposed new fleet.

NASA has “fears with the potential for a sizeable maximize in the frequency of conjunction occasions and attainable impacts to NASA’s science and human spaceflight missions,” the company stated in the letter, which was signed by Samantha Fonder, recognized as NASA’s consultant to the Professional House Transportation Interagency Team.
“NASA would like to guarantee that the deployment of the Starlink Gen 2 process is done prudently, in a fashion that supports spaceflight security and the very long-expression sustainability of the house surroundings,” the letter adds.
In accordance to the letter, NASA has significant issues about whether or not SpaceX’s automatic collision avoidance system would be plenty of to include the five-fold improve of objects in orbit. All of these countless numbers of new satellites will most likely have an effect on both crewed and uncrewed missions in orbit, the agency says, owing to an “boost in conjunctions” or close encounters with other objects.
This not only produces and raises collision hazard, but it also adds launch possibility, as there would be much less launch windows accessible owing to thousands more satellites passing in a rocket’s planned flight path.
“NASA is also worried with an growing unavailability of secure launch windows, in particular for missions requiring instantaneous or brief start home windows,” the company stated, citing the Europa Clipper mission as an example.
SpaceX’s Gen 2 satellites will also foreseeably induce problems for existing scientific missions. The new satellites could double the number of Hubble Space Telescope visuals that comprise satellite streaks. That volume of interference now stands at 8%, the agency mentioned.
Even worse, these added Starlink satellites could worsen the danger of interference with planetary defense surveys done by floor-primarily based telescope, which NASA works by using to scan the skies for possibly threatening asteroids (no imminent celestial objects have yet been found for our planet.)
The company, on the other hand, did not specific specific opposition to the FCC granting SpaceX a license for Starlink Gen 2, but as a substitute mentioned that such an enlargement would demand near coordination with other influenced get-togethers. SpaceX, which almost never responds to media inquiries, did not reply to a SpaceNews request for a response.
