Indian Space Program: News & Discussion

Up to third stage was normal. No news so far about fourth stage ignition. Hopefully it is only a delay of some sort.

Now, launch streaming is stopped.
From the graphics, it appeared that when the 3rd stage ended and the coast phase began, the rocket lost its attitude.
Briefly later, the info display showed that PS4 had ignited.

Seems it was a failure. Some spinning of the satellite observed.

Probably DRDO needs to launch it's own satellites .. under secrecy.. or use only whetted people for the high profile ones

‘Deviation seen in third-stage': Isro’s PSLV-C62 mission fails

A workhorse PSLV suffering two successive 3rd stage failures is unbelievable. The C-61 FAC has not determined the exact cause of that failure yet.

SRIHARIKOTA: The Indian Space Research Organisation (Isro) on Monday said that the PSLV-C62 mission encountered an anomaly during end of the PS3 stage and a detailed analysis has been initiated.

"Today we have attempted the PSLV C62 / EOS - N1 Mission. The PSLV vehicle is a four stage vehicle with two solid stages and two liquid stages," Isro chief V. Narayanan said.

"The performance of the vehicle close to the end of third stage was as expected. Close to the end of third stage we are seeing more disturbance in the vehicle. Subsequently, there is a deviation in the vehicle observed in the flight path. We are analysing the data and will come shall come back at the earliest," he added.

Isro launched EOS-N1, along with 14 co-passenger satellites and a capsule into a re-entry trajectory in a marathon mission, marking the space agency’s first mission of 2026.

The flight comes months after a rare setback, when PSLV-C61, launched on May 18, 2025, failed to place the EOS-09 earth observation satellite into orbit due to a third-stage anomaly.

This is bad. Once is happenstance, twice is coincidence, thrice is enemy-action

PSLV was carrying a hyperspectral satellite - a strategic payload

Our IRNSS network is hanging by a thread. PSLV two consecutive failures. Our launch rates have plummeted while other countries and even private companies are surging ahead

Its either sabotage or a serious drop in in morale/discipline at ISRO (or) both

If we recall the Stuxnet worm, it was so sophisticated that all the accidents looked random. Its entirely possible that some deep-state actors are at play. Even if failures have different root-causes, it does not rule out sabotage. It could probably be an advanced form of sabotage

Plus, ISRO needs a kick up its rear too. Focusing too much on vanity projects like Gaganyaan when strategic projects are dying on the vine. For comparison, China has 100s of milsats in orbit

Why can't they just launch instead of such fanfare, I think sabotage is happening at private company factory itself masking component failure.
Hope in future they do this quietly like boomers or at least don't mix civilian and strategic payloads
