URGENT MESSAGE: From TS Kelso of CelesTrak "[The US Space Force 18th Space Defense Squadron] will run out of 5-digit catalog numbers at 69999 not 99999, which is estimated to occur around 2026‑07‑20 (we're currently at 68014). At that point, newly cataloged objects will have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format. CelesTrak developed new formats that removed this limitation (and finally fixed the Y2K problem) in May ...Continue Reading
