SpaceX launches Space Safety page urging satellite operators to share ephemeris data

SpaceX has published a new “Space Safety” page calling on every satellite operator to share ephemeris data proactively and adopt the company’s collision-avoidance standards, with the @Starlink account posting the public call on Tuesday.

According to SpaceX’s own figures, Starlink encountered collision risks with about 650 unique manoeuvring third-party satellites in 2026, with only around half sharing trajectory data. The company claims it recorded roughly 164,000 further collision risks over six months where the closest approach came within four hours of an unannounced manoeuvre. Starlink engineering vice president Mike Nicolls presented the case at a lecture at the International Astronautical Federation conference in Turkey, Behind The Black reported.

SpaceX is offering a free ephemeris-sharing and screening platform that returns conjunction risk results within a minute, backed by its Stargaze network of 30,000 optical sensors, which the company says tracks half of all objects below 600 km perigee — details at space-safety.starlink.com.

As an example, SpaceX points to December 2025, when it says a satellite deployed from a CAS Space Kinetica 1 rocket came within about 200 metres of STARLINK-6079 at 560 km altitude without coordination. CAS Space disputed the claim, responding that all its launches use ground-based space-awareness systems to select collision-avoiding launch windows as a mandatory procedure, and that the satellite was no longer under its direct control when the encounter occurred (TechSpot).
