"Earlier this morning, from our South American site, we captured a low-elevation pass of SpaDeX-A (SDX01) and SpaDeX-B (SDX02) at 09:30 AM IST. These two spacecraft, currently separated by an estimated 4.5 km, are setting the stage for the groundbreaking docking of the
ISRO SpaDeX Mission."

"The SpaDeX Docking scheduled on 7th is now postponed to 9th.
The docking process requires further validation through ground simulations based on an abort scenario identified today."

‪s2a systems‬ on bsky: SpaDeX A and SpaDeX B over South America. Recorded on 2025-01-06 at 03:58:42 UTC. Distance: about 4 km.

And Chethan Dash of ToI just informed on X that docking event has been postponed to 9 January.

"Video Captured by Video Monitor Camera onboard SPADEX on 2nd Jan 2025 10:27 hrs IST"

"Selfie video of the chaser is recorded during chaser approaching totarget at the Inter-satellite distance (ISD) of 4.8 km on 2nd Jan 2025 10:27 hrs IST.
Further VM will provide real time visualization of docking event during capturing process of twin spacecrafts."

On X they noted that the distance between satellites is about 5.7 km

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.
