海外TECH	Engadget	Starlink is lowering thousands of satellites' orbits to reduce risk of collisions	https://www.engadget.com/science/space/starlink-is-lowering-thousands-of-satellites-orbits-to-reduce-risk-of-collisions-030509067.html?src=rss	Starlink will lower the orbits of roughly satellites this year as a safety measure according to engineering VP Michael Nicolls In a post on X Nicolls wrote that the company is quot beginning a significant reconfiguration of its satellite constellation quot in which all satellites orbiting at around kilometers miles will be lowered to around km miles The move is intended to reduce the risk of collisions putting the satellites in a region that s less cluttered and will allow them to deorbit more quickly should an incident occur nbsp quot Lowering the satellites results in condensing Starlink orbits and will increase space safety in several ways quot Nicolls wrote also pointing to the coming solar minimum ーa period in the sun s ish year cycle when activity is lower ーas one of the reasons for the move The next solar minimum is expected to occur in the early s quot As solar minimum approaches atmospheric density decreases which means the ballistic decay time at any given altitude increases lowering will mean a gt reduction in ballistic decay time in solar minimum or years reduced to a few months quot Nicolls wrote A screenshot of an X post by Starlink VP of engineering Michael Nicolls announcing that satellites orbiting at around kilometers will be lowered to kmThe announcement comes a few weeks after Starlink said one of its satellites had experienced an anomaly that created some debris and sent it tumbling Just a few days earlier Nicolls posted about a close call with a batch of satellites he said were launched from China seemingly without any attempt to coordinate with operators of existing satellites in the space With his latest announcement Nicolls added that lowering Starlink s satellites quot will further improve the safety of the constellation particularly with difficult to control risks such as uncoordinated maneuvers and launches by other satellite operators quot This article originally appeared on Engadget at	2026-01-02 03:05:09
