Honestly, these two paragraphs are one of the most compelling things they could possibly say in a press release:

> Stargaze already has a proven track record in its utility for space safety. In late 2025, a Starlink satellite encountered a conjunction with a third-party satellite that was performing maneuvers, but whose operator was not sharing ephemeris. Until five hours before the conjunction, the close approach was anticipated to be ~9,000 meters—considered a safe miss-distance with zero probability of collision. With just five hours to go, the third-party satellite performed a maneuver which changed its trajectory and collapsed the anticipated miss distance to just ~60 meters. Stargaze quickly detected this maneuver and published an updated trajectory to the screening platform, generating new CDMs which were immediately distributed to relevant satellites. Ultimately, the Starlink satellite was able to react within an hour of the maneuver being detected, planning an avoidance maneuver to reduce collision risk back down to zero.

> With so little time to react, this would not have been possible by relying on legacy radar systems or high-latency conjunction screening processes. If observations of the third-party satellite were less frequent, conjunction screening took longer, or the reaction required human approval, such an event might not have been successfully mitigated.

Looks like a non-trivial upgrade to previous systems, and they're making Stargaze's data available to other satellite operators free of charge. Nice!

Now I would really love to know who the other operator was.

> In a statement posted on social media late Dec. 12, Michael Nicolls, vice president of Starlink engineering at SpaceX, said a satellite launched on a Kinetica-1 rocket from China two days earlier passed within 200 meters of a Starlink satellite.

> CAS Space, the Chinese company that operates the Kinetica-1 rocket, said in a response that it was looking into the incident and that its missions “select their launch windows using the ground-based space awareness system to avoid collisions with known satellites/debris.” The company later said the close approach occurred nearly 48 hours after payload separation, long after its responsibilities for the launch had ended.

> The satellite from the Chinese launch has yet to be identified and is listed only as “Object J” with the NORAD identification number 67001 in the Space-Track database. The launch included six satellites for Chinese companies and organizations, as well as science and educational satellites from Egypt, Nepal and the United Arab Emirates.

This is funny, the way things are just discarded in space, not our problem anymore vs. deorbit

If you get hit by a car 5 minutes after you get let off at a bus stop it isn't the bus drivers fault.

Yeah while I didn't directly mention it, I'm referring to stages being discarded in space by a specific party
