Concerns Over Radiation Emission from Elon Musk's Starlink Satellites
Written on
Chapter 1: Understanding Starlink Satellite Emissions
Recent research set to be published in the Journal of Astronomy and Astrophysics highlights that the constellation of Starlink satellites is emitting "unintended radiation." However, this is not the radioactive type many might envision. Instead, it involves a specific form of electromagnetic radiation.
Using the Low Frequency Array (LOFAR) telescope, researchers measured the low-frequency radio signals emitted by 47 out of 68 observed satellites. Alarmingly, some of these frequencies fall within the spectrum reserved solely for radio astronomy.
Cees Bassa, an astronomer from the Netherlands Institute for Radio Astronomy, remarked, “This frequency range includes a protected band between 150.05 and 153 MHz specifically allocated to radio astronomy by the International Telecommunications Union.” If these satellites emit excessive amounts of restricted radio frequencies, it could lead to significant interference in radio astronomy, particularly in deep space investigations.
This measurable leakage is likely already affecting ongoing radio-astronomy research.
Section 1.1: Implications of Radio Emissions
While we are not facing hazardous radioactive fallout, the impact on astronomers could be substantial. The interference might disrupt critical deep space studies, where the signals from distant celestial objects are often weak and easily overwhelmed. Identifying the source of interference will become increasingly challenging as it blends with the radio astronomy signals.

Section 1.2: The Future of Starlink and Its Impact
Currently, over 4,000 Starlink satellites orbit the Earth, providing service to more than 1 million subscribers across 56 countries. Elon Musk's ambition is to escalate this number to over 12,000 satellites in the coming years. Despite the concerns regarding radiation emissions, Musk continues to launch additional satellites, with the latest deployment occurring last Sunday.
Notably, the researchers indicated that similar unintended emissions are anticipated from other satellites in low-Earth orbit, and further studies are planned to investigate other satellite constellations. The scientific community is increasingly concerned about the future of terrestrial space studies, not solely due to radiation but also due to other forms of pollution, such as light interference.
