Space is getting crowded, and a recent near-miss between a Chinese spacecraft and a SpaceX Starlink satellite highlights the growing dangers of orbital congestion.
On December 9th, a Chinese Kinetica 1 rocket launched nine spacecraft into orbit. One of these, unfortunately, came alarmingly close to a Starlink internet satellite, prompting serious concern from SpaceX.
According to SpaceX, the close approach, a mere 200 meters at an altitude of 560 km, occurred without any prior coordination or deconfliction with existing satellites. This lack of communication is a significant issue, as it increases the risk of collisions. Michael Nicolls, SpaceX's vice president of Starlink engineering, expressed his concerns on X (formerly Twitter), emphasizing the urgent need for better cooperation among satellite operators.
The Kinetica 1 rocket, operated by CAS Space, is a 100-foot-tall (30 meters) solid-fuel rocket. CAS Space responded to the incident, stating that they follow mandatory procedures to avoid collisions and are investigating the matter further. The launch itself deployed a variety of satellites, including Chinese multifunctional satellites, an Earth-observation satellite for the UAE, a scientific satellite for Egypt, and an educational satellite for Nepal.
But here's where it gets controversial... The core of the problem lies in the rapidly increasing number of satellites orbiting Earth. In 2020, there were fewer than 3,400 functional satellites. Just five years later, this number has skyrocketed to approximately 13,000, with more being launched constantly. This dramatic increase in space traffic necessitates better coordination to prevent collisions.
SpaceX, with its massive Starlink constellation, is a major player in this domain, currently operating nearly 9,300 satellites. The company has launched over 3,000 satellites this year alone. Starlink satellites are designed to autonomously avoid collisions by maneuvering based on tracking data. They are quite active, performing about 145,000 avoidance maneuvers in the first six months of 2025, averaging about four maneuvers per satellite per month.
And this is the part most people miss... The challenge isn't just about the sheer number of satellites. It's also about the lack of data sharing and coordination between different operators. Even the most advanced collision-avoidance systems can be caught off guard if they don't have access to accurate trajectory information from other spacecraft.
Even a single collision could generate a cascade of debris, potentially leading to the Kessler syndrome, a scenario where the density of space debris becomes so high that it makes it difficult or impossible to operate satellites.
What are your thoughts on the growing congestion in Earth's orbit? Do you think current regulations and coordination efforts are sufficient, or do we need more robust international agreements to ensure the long-term sustainability of space activities? Share your opinions in the comments below!
