   NOTAM issued for PSLV-C60/SpaDEx (Space Docking Experiment).

   Enforcement duration 1600-2000 (UTC), 30 December 2024 to 13 January 2025.

   https://en.wikipedia.org/wiki/SPADEX

   Fourth stage (PS4) will be configured as POEM-4 orbital platform to host few payloads from Indian space-startups.

     Three objects cataloged

     62459 ( 24253A )
     i=54.99°, A×P=476.32×469.14 km

     62460 ( 24253B )
     i=54.99°, A×P=476.40×469.26 km

     62461 ( 24253C )
     i=55.05°, A×P=475.43×356.84 km

     Last one should be POEM-4, cataloged before achieving 350 km circular orbit perhaps.

     If PSLV-C60/SpaDeX launches as scheduled from FLP, it will be the shortest period between two consecutive orbital launches for ISRO from same pad at 25.25 days after PSLV-C59/PROBA-3 launch on 5 December.

     Previous shortest gap was 31.02 days between GSLV-F09/GSAT-9 and GSLV MkIII-D1/GSAT-19 from SLP.

     ISRO began purging EXIF data as we used to use that to figure out launch campaign process and any oddities in it.
