SpaceX calls for better coordination in orbit after near-misses with Starlink
“These led to conjunctions of tens of meters to hundreds of meters. Way too close to comfort.”
TL;DR
- SpaceX is advocating for enhanced data-sharing among satellite operators to ensure safe operations in orbit.
- Near-miss incidents involving Starlink satellites and other operators' spacecraft underscore the risks of uncoordinated maneuvers.
- Michael Nicolls, VP of Starlink and President of xAI, emphasized that sharing satellite location and trajectory data (ephemeris) is vital for preventing collisions.
- The increasing number of satellite constellations, including SpaceX's Starlink and Amazon's Project Kuiper, amplifies the need for space traffic management.
- While SpaceX shares its ephemeris data and implements collision avoidance systems like Stargaze, many operators, particularly some Chinese and Russian entities, do not share their data.
- Amazon Leo, a competitor, stated they actively coordinate with SpaceX and other operators, deeming ephemeris sharing a 'non-issue' for their company.
- SpaceX has adjusted the altitude of its Starlink constellation and plans to fly future satellites even lower to mitigate risks and improve service.
- Starlink satellites perform approximately 1,000 collision avoidance maneuvers daily, often avoiding active satellites from operators who do not share data.
