"Space Debris Collisions Generate Audible 'Noise' Detectable on Earth"

Collisions between space junk in orbit around Earth produce electrical bursts that can be detected from Earth using radio telescopes, according to a study by researchers from the University of Michigan. The method could help track the millions of tiny fragments of space debris that are currently invisible to current tracking methods but pose a threat to operating satellites. The researchers plan to conduct further simulations and compare their results with real signals measured by NASA's Deep Space Network. The increase in orbital debris raises concerns about the potential for devastating collisions and the Kessler Syndrome, an unstoppable cascade of collisions that threatens other spacecraft.

"Starlink Satellites: Dodging Objects, Leaking Radiation, and Disturbing Astronomy"

SpaceX's Starlink satellites have performed over 25,000 avoidance maneuvers in a six-month period, double the previous reporting period, as low Earth orbit becomes more crowded. The company uses a stringent threshold for maneuvering, moving satellites when the probability of collision exceeds 1 in 100,000. Over 1,300 maneuvers were made to avoid debris from Russia's anti-satellite weapon test. Additionally, a study found that Starlink satellites emit unintended electromagnetic radiation that could impact astronomical research, with simulations showing a compounding effect from larger constellations. The International Astronomical Union has been vocal about the potential impacts of satellite constellations on astronomy, and SpaceX has introduced changes to mitigate the emissions in the next generation of Starlink satellites.

The Looming Threat: Space Junk Endangers Satellite Survival

The risk of anti-satellite (ASAT) weapons was highlighted when Russia conducted a test in 2021, creating a cloud of debris that poses a threat to satellites and space missions. According to a research article, the cascade of collisions caused by shattered satellites could render Low-Earth Orbit (LEO) unusable in just 40 years. The growing problem of space debris from past tests and other space activities is threatening satellites and limiting the launch of additional satellites. The weaponization of outer space could lead to the destruction of most, if not all, satellites in orbit, with catastrophic consequences. Controlling satellite warfare may require the same level of deterrence as the nuclear arms race.
