Note that 18 SDS incorrectly identifies RAISE-4 as the ELECTRON R/B. Past Electron launches should make it easy to determine which objects are which. We will have to see whether 18 SDS reassigns (swaps) the data to match their IDs.

18 SDS now appears to have corrected the data for 2025-296B. Note the large difference in inclination, in addition to the orbital altitude: celestrak.org/NORAD/elemen....

*NOTE: The orbital data for 2025-296B appears to be something from the Guowang Group 16 launch (2025-295) rather than the DEAR-5 launch (2025-296): celestrak.org/NORAD/elemen.... And the data for the Guowang launch is still incomplete (only 6 of 10 objects).

A year and a half ago, 2024-06-06, we went over Catalog Number 59999. Yesterday, we passed 66999, meaning we have less than 3,000 catalog numbers left. At the rate for the last 1,000 (55 days), we have 165 days left or until 2026-05-24. Time is quickly running out to prepare.

Just found and fixed that this morning. Typed the wrong designation into the configuration, probably when I was bleary-eyed from working too late or not getting enough sleep. 😜 Sorry and thanks for keeping me on my toes!
