Starlink Lowers Thousands of Satellites' Orbits in Major Safety Move
In a significant step towards enhancing space safety, Starlink has announced plans to lower the orbits of approximately 4,400 satellites to around 480 kilometers (298 miles) above the Earth's surface. This move is expected to reduce the risk of collisions among satellites and allow them to deorbit more quickly in case of an incident.
According to Michael Nicolls, engineering VP at Starlink, the company is undertaking a "significant reconfiguration" of its satellite constellation. By lowering the orbits of all satellites currently circling at 550 kilometers (342 miles), the risk of collisions will be significantly reduced. The new orbits also place the satellites in an area that is less cluttered and more conducive to safe operations.
The move comes as solar activity is expected to decrease, leading to a reduction in atmospheric density over time. In essence, this means that satellites currently in lower orbits may remain aloft for longer periods before burning up in the atmosphere. By lowering their orbits now, Starlink hopes to shave years off their expected lifespan and reduce the overall risk of debris accumulation.
The decision has been made in light of recent incidents, including a near-miss with another satellite launched from China without prior coordination with existing operators. Additionally, one of Starlink's own satellites experienced an anomaly that created debris and forced it into a tumble.
With its latest announcement, Starlink aims to further improve the safety of its constellation by mitigating difficult-to-control risks such as uncoordinated maneuvers and launches by other satellite operators. The move marks a significant step forward in prioritizing space safety and minimizing the impact of human activity on low Earth orbit.
