Starlink Lowers Satellite Orbits for Enhanced Safety
In a move aimed at reducing the risk of collisions and improving space safety, Starlink will lower the orbits of roughly 4,400 satellites this year. According to Michael Nicolls, engineering VP at Starlink, the company is “beginning a significant reconfiguration of its satellite constellation,” which will involve lowering all satellites orbiting at around 550 kilometers (342 miles) to approximately 480 km (298 miles).
The decision comes as a response to concerns over the increasing clutter in space and the potential risks associated with it. By condensing the orbits, Starlink aims to reduce the risk of collisions between its own satellites and those operated by other companies or countries.
Reducing Collisions and Increasing Deorbiting Times
The reconfiguration is intended to achieve several benefits, including reducing the risk of collisions, putting the satellites in a region that’s less cluttered, and allowing them to deorbit more quickly should an incident occur. According to Nicolls, this will result in a >80% reduction in ballistic decay time during solar minimum, or 4+ years reduced to a few months.
The announcement comes just weeks after Starlink reported an anomaly that created debris and sent one of its satellites tumbling. Additionally, Nicolls recently posted about a close call with a batch of satellites launched from China without any attempt to coordinate with operators of existing satellites in the space.
Avoiding Space Debris and Enhancing Safety
By lowering its satellite orbits, Starlink aims to further improve the safety of its constellation, particularly with difficult-to-control risks such as uncoordinated maneuvers and launches by other satellite operators. The move is also intended to prepare for the upcoming solar minimum, which is expected to occur in the early 2030s.
As the world continues to rely on space-based technologies, it’s essential that companies like Starlink take proactive measures to ensure the safety and sustainability of their operations. By condensing its satellite orbits and reducing collision risks, Starlink demonstrates its commitment to responsible innovation and environmental stewardship in space exploration.
