Somanath said next year the commercial arm NewSpace India Ltd (NSIL) has contracted two launches.

One of them will be for the UK based satellite communications company OneWeb to orbit the second batch of 36 satellites.

The other launch should be PSLV C55.

From the post launch speeches after the successful launch of SSLV D2:

Quote from: Steven Pietrobon on 02/10/2023 03:34 am

Preparing GSLV Mk.III for 36 OneWeb satellites in middle of March. Commencing launch campaign immediately after today's launch for PSLV C55 for end of March on commercial mission. Using new facility. Preparing for landing demonstration of RLV in a few days time.

For Gaganyan have abort and recovery mission today, another abort and recovery mission and trying for uncrewed mission before end of year.

GSLV for NAVIC series satellite prior to NISAR, scheduled for end of this year. More PSLV missions as well.

Thanks to a tip by forum member Ohsin here, there's this document which shows PSLV s/n C55 as launching with TeLEOS 2 of Singapore.

Reddit's ISRO sub-reddit lists this as in April, although I can't find a source. NET April would be appropriate though given the OneWeb launch now on NET March 26 already.

Launch vehicle should be a PSLV-CA, assuming there are no other similarly-massed payloads aboard, and that the upper stage will not maneuver extensively after deploying TeLEOS 2.

Launch preparations for PSLV-C55 are in full swing at Sriharikota with a tentative launch date on 22nd April!

The 1st and 2nd stages have already been integrated and transferred to FLP for integration with 3rd & 4th stages & PLF+payload assembly. #ISRO #PSLVC55

Quote

In previous PSLV missions, the entire vehicle was integrated at the FLP with the help of MST.

But from this mission onwards, the 1st & 2nd stages will be integrated at the new PIF facility, be transferred to MST/FLP (via FLP's new MLP) for rest of integration work & launch.

Quote

These changes to launch operations were made to allow the partial integration of a PSLV vehicle even when the FLP is occupied by another PSLV vehicle, thus increasing launch frequency.

FLP = First Launch Pad
MST = Mobile Service Tower
MLP = Mobile Launch Pedestal
PLF = Payload Fairing

. In addition to TeLEOS-2 there is apparently also a 12U cubesat on board named Lumelite-4 on board, also from Singapore (not sure who's the owner). In addition 8 non-separable payloads will fly attached to the 4th stage operating in the POEM (PSLV Orbital Experimental Module) configuration for the 2nd time.

Planned orbit: 585 km, 10° inclination LEO.

It’s possible a fuel tank from this mission has washed up on a beach in Western Australia.

Quote

The Australian Space Agency, which is also part of the investigation, said it was looking into the possibility that it could be a part of a foreign space launch vehicle.

“The agency is working to confirm whether the object could be part of a foreign space launch vehicle that has washed up on shore, and liaising with global counterparts who may be able to provide information about the object,” a spokesperson for the agency said.

“As the origin of the object is unknown, the community should avoid handling or attempting to move the object.”

Experts said that the object could be a part of India’s satellite launch to the moon. It is suspected to be the fuel tank of the Polar Satellite Launch Vehicle (PSLV) rocket. The latest PSLV mission was the PSLV-55 that was successfully launched in April this year.

This mission went into a low inclination orbit of 10°. Third stage separation occurred at T+586.68 s (9m46.68s) at an altitude of 350 km heading towards space. Not sure where re-entry would be but it would be quite a bit east of India. Someone could work this out from the telemetry that was shown. That's a fairly long trip to Green Head, Western Australia, where the stage was recovered! The previous C54 launch was to a polar orbit, so the third stage probably has an easier path to get to Western Australia.
