CelesTrak has GP data for 1 object from the launch (2026-045) of EchoStar 25 atop a Falcon 9 rocket from Cape Canaveral on Mar 10 at 0419 UTC: spaceflightnow.com/2026/03/09/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....
This is a very interesting debate. At what point does an AI tool switch from a tool to "practicing law"? I expect this will be one of many such debates (and lawsuits) as more work is transitioned from white collar professions to AI.

CelesTrak has ephemeris-based SupGP data for all 29 satellites from the Starlink G10-40 launch (2026-042) atop a Falcon 9 rocket from Cape Canaveral on 2026-03-04 at 10:52:20 UTC: spaceflightnow.com/2026/03/03/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....
1/ In todayβs summary (celestrak.org/satcat/), these 141 active satellites include 4 lost ones with SupGP data (celestrak.org/NORAD/elemen...). The GP data for O3B MPOWER F10 is now 208 days old, even though the SupGP data is current within the past day (celestrak.org/NORAD/elemen...) & < 50 m RMS.
1/ COSMOS 2591-2594, launched 2025-08-21 from Plesetsk Cosmodrome (celestrak.org/satcat/table...), appear to be conducting VLEO operations at 280-289 km altitude. Graphs for each are linked in the Latest Data column of the table (e.g., celestrak.org/NORAD/elemen...).
CelesTrak has ephemeris-based SupGP data for all 29 satellites from the Starlink G10-41 launch (2026-041) atop a Falcon 9 rocket from Cape Canaveral on 2026-03-02 at 02:56:40 UTC: spaceflightnow.com/2026/03/01/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....
CelesTrak has ephemeris-based SupGP data for all 25 satellites from the Starlink G17-23 launch (2026-040) atop a Falcon 9 rocket from Vandenberg SFB on 2026-03-01 at 10:10:39 UTC: spaceflightnow.com/2026/03/01/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....
1/ We regularly see statistics showing the number of objects in Earth orbit and they are often woefully incorrect and lack specifics or citations. We now provide all of that information in one place on CelesTrak at celestrak.org/satcat/.

TinyGS (tinygs.com) now has more than 2200 ground stations. In addition to identifying satellites, they are now identifying cross-tagged satellites.
Cross-Tagging is a growing problem, especially with LEO megaconstellations. Cross-tagged sats identified to CelesTrak are corrected in our data.
CelesTrak has ephemeris-based SupGP data for all 29 satellites from the Starlink G6-101 launch (2026-020) atop a Falcon 9 rocket from Cape Canaveral on 2026-01-30 at 07:22:00 UTC: spaceflightnow.com/2026/01/30/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....
What a great step forward!
Ephemeris sharing is the right answer!
All operators need to be working with the highest quality data possible. Providing Spaceflight Safety and Conjunction data free of charge removes barriers which is in the best interest of all. #SpaceSafety #SpaceX #Stargazer

No SATCAT data from 18 SDS for 2026-004 (Twilight, 40+), -005 (Starlink G6-97, 29), -008 (Starlink G6-98, 29), -011 (NROL-105, ?), -012 (Starlink G6-100, 29), -013 (GuoWang Group 19, 10): celestrak.org/satcat/table.... In addition, no GP for those or 2026-010 (Tianqi 37-40, 4+).
Is this acceptable?

This event does provide an opportunity for comparison analysis across SSA data sources: Government, Commercial, SupGP, etc. It could be a valuable case study providing insight for data sharing and open data discussions.

Are the Chinese giving us the ride to the Moon because 2028 seems...ambitious, given how Starship is faring. Also this changes the directive to provide SSA data for free, instead saying that it should be available "for commercial and other relevant use"

Every time I see the issue of providing, sharing, or public SSA data I am reminded of a Dr. T.S. Kelso quote from years ago.
