What's Happening?
On December 12, a SpaceX Starlink satellite narrowly avoided a collision with a newly launched satellite from China. The incident occurred at an altitude of 560 kilometers, with the two satellites coming within 200 meters of each other. SpaceX's vice
president of engineering, Michael Nicholls, stated that there was no prior coordination or deconfliction with existing satellites, leading to the close approach. The Chinese satellite was launched by CAS Space just 48 hours before the near-miss. The lack of an international space surveillance and coordination system is highlighted as a significant issue, with experts like astronomer Jonathan McDowell calling for a system that includes both the U.S. and China to ensure safe space operations.
Why It's Important?
The near-collision underscores the growing risk of space debris and the potential for Kessler Syndrome, where cascading collisions could render space inaccessible. As more countries and private companies launch satellites, the lack of a coordinated space traffic management system increases the likelihood of accidents. Such incidents could have severe consequences, including the creation of debris that threatens other satellites and the potential for debris to fall to Earth, causing damage. The event highlights the urgent need for international cooperation to establish protocols for satellite launches and operations to prevent future incidents.
What's Next?
The incident may prompt discussions among international space agencies and private companies to develop a comprehensive space traffic management system. Stakeholders might push for agreements on satellite deconfliction and coordination to prevent similar occurrences. The event could also lead to increased advocacy for regulatory frameworks governing space operations, potentially involving the United Nations or other international bodies. As space becomes more congested, the pressure to address these issues will likely grow, with potential implications for future satellite launches and space exploration missions.
