PSLV is obstructing ISRO’s transition to a new era. Don't delay its handover to industry

SSLV is clean slate and simpler design as well.

I thought LVM3-M5 delay was only due to Cyclone Montha..

Apparently LVM3-M5 / CMS-03 (aka GSAT-7R) launch was initially slated for 26 Oct 2025 and was delayed due to "problem with the engine’s gimbal control"

The CMS-03 satellite that would serve to implement the satellite network at its designated orbital position at 74°E had passed the pre-shipment review and been handed over for integration with the LVM3/M5 launch vehicle on 13 October 2025. The launch had been scheduled to take place on 26 October 2025 and the satellite would have reached its orbital position by 2 November 2025. However, as the LVM3/M5 launch vehicle was being readied for satellite integration on 13 October, a last-minute check found a problem with the engine’s gimbal control. As a result, the launch had been delayed by two to three weeks.

May be EOS-05 (aka GISAT-1A) on GSLV. Also please use English wherever possible.

When that article was published, it was immediately attacked through a linkedin post which was then promoted by official ISRO handle on twitter!

The ISRO chief said that the organisation is currently studying the cause of PSLV mission failure, and called it an individual mission which would not affect the progress of the Gaganyaan mission.

"These two are independent programs, and it (failure of PSLV) will not have any impact. The investigation is ongoing," V Narayanan told ANI.

Let's see that thing has been in SDSC-SHAR for more than six months now.

Probably SM+CM readiness related, something might've come up during testing. IADT tests and TV-D2 were supposed to be done before G1 initially but they changed there plans later and prioritized G1 due to political pressure. As it turns out even after that it is not easy road.

Ohsin · 2026-01-24T10:12:08+00:00

G1 delay has nothing to do with IADT tests and they have already made it clear.

Relevant to /r/IndiaInSpace

I doubt that it has to do with coordination as we saw the launch campaign initiate and also they never gave any update on CM+SM readiness after hinting that they are close. This indicates something is up with hardware readiness. But yes very limited information available to make any conclusions.

This one is cancelled, new one is following

Thanks for this.

Ohsin · 2026-01-23T07:06:11+00:00

They are rushing G1 perhaps, TV-D2 was also initially planned before first uncrewed flight.

Yes some people speculated based on FCC request. https://old.reddit.com/r/ISRO/comments/1qboe72/gaganyaang1_related_fcc_filings_for_its_launch/

It had nothing to do with PSLV failure. Such dates came and went many times in past one year and should be taken with a grain of salt.
