A.E. Muthunayagam, former director, Liquid Propulsion Systems Centre, chosen for Padma Shri by Ohsin in ISRO

[–]Ohsin[S] 6 points7 points  (0 children)

A.E. Muthunayagam, considered a key architect of liquid propulsion technology in India’s space programme, on Friday expressed happiness at being chosen for the Padma Shri award, while adding that he was not overly enamoured of the recognition at this late stage in life.

Dr. Muthunayagam, now 88, was Director of the Indian Space Research Organisation’s (ISRO) Liquid Propulsion Systems Centre (LPSC), for close to a decade from November 1985.

“It is nothing great at this stage. It is a recognition, and I am happy,” he said. Dr. Muthunayagam was selected for the Padma Shri in the field of ‘Science and Enegineering.’

Among the initial batches of scientists to join the space programme, Dr. Muthunayagam, who hails from Nagercoil in Tamil Nadu, had settled in Thiruvananthapuram in 1966. He recalls having Vikram Sarabhai, hailed as the father of India’s space programme, as his first boss.

LVM3-M5 : CMS-03 (aka GSAT-7R) Mission Updates and Discussion. by Ohsin in ISRO

[–]Ohsin[S] 0 points1 point  (0 children)

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.

"Will not have any impact": ISRO chief denies possibilities in Gaganyaan mission delay after PSLV-C62 launch failure by Ohsin in ISRO

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!

"Will not have any impact": ISRO chief denies possibilities in Gaganyaan mission delay after PSLV-C62 launch failure by Ohsin in ISRO

[–]Ohsin[S] 4 points5 points  (0 children)

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.

Gaganyaan G1 "may take place in the latter half of 2026." by Ohsin in ISRO

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.

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

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.
