Introduction
Elon Musk stated on Thursday that SpaceX’s Starlink satellite internet service can now provide symmetrical, reliable upload and download connectivity at speeds of up to 10 gigabits per second anywhere on Earth. This claim represents a massive leap for satellite-based broadband, but it comes amid growing scientific concern over the company’s lofty orbital ambitions and their widespread impacts.
Trial success in Alaska and the global promise
The announcement follows a successful Starlink demonstration in Utqiagvik, Alaska, the northernmost city in the United States, located 320 miles above the Arctic Circle and inaccessible by road. Starlink posted on the X platform on July 9 that it delivered peak speeds of up to 10 gigabits per second in the remote community. Musk then confirmed on X that the capability now extends worldwide. Starlink added that interconnected gateways can provide up to 20 gigabits per second of symmetrical service for harsh environments. This achievement relies on Starlink’s third-generation satellites, which Musk previously said will deliver 10 times the bandwidth of older units, reaching 1 terabit per second per satellite. As of early July, SpaceX has deployed more than 10,400 Starlink satellites and has over 12 million subscribers.
Astronomers’ concerns and fears
The speed breakthrough comes in light of a study published in late June by the European Southern Observatory warning that plans to launch more than 1.7 million satellites—with SpaceX alone seeking approval for 1 million of them—will have devastating consequences for ground-based astronomy. The research found that for the observatory’s Very Large Telescope in Chile, images taken two hours after nightfall could lose up to 28 percent of their clear field of view due to the bright streaks left by satellites in the night sky.
Balance and future challenges
Lead researcher Olivier Hainaut called for a strict cap of 100,000 satellites in orbit, with all of them kept below the naked-eye visibility threshold to preserve the continuity of research. According to additional reports, the proliferation of orbital hardware could brighten the sky by 3 to 4 times, obscuring observations of faint galaxies, exoplanets, and potentially hazardous asteroids. Starlink’s technical achievement underscores the tension between expanding global connectivity and protecting scientific infrastructure. Although SpaceX has previously worked with astronomers to reduce satellite brightness, the study indicates that these efforts will be insufficient for the scale envisioned by Musk, while questions remain over whether regulators will impose strict limitations.
Frequently asked questions
Question: What is the maximum speed announced by Musk for the Starlink network around the world?
Answer: Musk stated that the network now provides ultra-fast connection speeds of up to 10 gigabits per second globally and in the most remote areas.
Question: Why are scientists expressing concerns about SpaceX’s space ambitions?
Answer: Because of the massive light pollution caused by dense satellites in orbit, which disrupts precise astronomical observations from ground-based telescopes.
Question: What is the solution proposed by the European Southern Observatory?
Answer: They propose setting a maximum deployment limit not exceeding 100,000 satellites and dimming their brightness to ensure the continuity of astronomical research.
