ISRO LVM3-M5 Mission successful placed CMS-03 communiation satellite in orbit: Highlights

PM Modi appreciated the space sector via post on X (formerly known as Twitter). He wrote: 

"Our space sector continues to make us proud!" 

"Congratulations ISRO on the successful launch of India’s heaviest communication satellite, CMS-03." 

"Powered by our space scientists, it is commendable how our space sector has become synonymous with excellence and innovation. Their successes have furthered national progress and empowered countless lives."

After the successful placing of the heaviest satellite in the orbit, Chairman of ISRO- Dr V Narayan appreciated LVM3 rocket, stating it brought glory to India once again.

The Chairman of ISRO congratulated the team, who worked for this challenging mission – weather was not cooperative. Dr Narayanan congratulated the team who worked LVM3-M5 mission, along with their families who cooperated and helped to make the mission successful.  

CMS-03 separated successfully and reached the transfer orbit.

Finally CMS-03 satellite separated and has been injected to the intended orbit- smoothly!

After Gaganyaan-3, LVM3 lift off for its fifth space mission. It is heading smoothly in the space towards the Geosynchronous Transfer Orbit.

LVM3 is moving at a precise pace and heading towards the Geosynchronous Transfer Orbit. Performance is normal so far, stated ISRO officials.

C25 is thrusting normally and moving smoothly to the destination (Geosynchronous Transfer Orbit).

First stage perfomance of LVM3-M5 reportedly normal, and L1-10 stage is heading on to second stage smoothly- ISRO updated

LVM3-M5 susccessfully lift off from Sriharikota

The mission director of the LVM3–M5 CMS-03 mission has directed to start the automatic launch sequence.

Automatic launch sequence have been initiated- and in 14minutes the rocket will be lift off. All the checkups have been done.

• CMS-03 is a multiband communication satellite, weighing 4,410 kg — ISRO’s heaviest-ever satellite to be launched from Indian soil into GTO.
• Will be placed in a 29,970 km × 170 km transfer orbit.
• Marks India’s first launch of a satellite this heavy on its own rocket.
• Earlier, ISRO had to rely on foreign space agencies for launching heavier satellites.
• CMS-03 will be launched aboard the LVM3 ‘Bahubali’, ISRO’s most powerful heavy-lift rocket.

• LVM3, previously known as GSLV Mk-III, is ISRO’s heavy-lift launch vehicle.
• It has completed seven consecutive successful missions, proving high reliability.
• Uses a combination of solid, liquid and cryogenic engines for powerful lift.
• Can carry up to 8,000 kg to Low Earth Orbit (LEO) and up to 4,000 kg to Geosynchronous Transfer Orbit (GTO).
• LVM3-M5 marks the fifth operational flight of this rocket series.

The LVM3-M5 will launch in Sriharikota (AP) which is the Second Launch Pad (SLP) of the Satish Dhawan Space Centre (SDSC or SHAR).

The ISRO YouTube is live now at 4:56PM IST, and checking procedure started. 

LVM3 is set to go for its 5th operational flight till date. It's last mission was the Chandrayaan-3, where India became the first country to land near the lunar south pole successfully.

CMS-03 weighs around 4400 kg and is said to be the heaviest communication satellite to be lifted off to Geosynchronous Transfer Orbit (GTO) from the Indian soil. 

ISRO's CMS-03 is a multi-band communication satellite which wilkl be able to provide services over a wide oceanic region around the Indian landmass. 

India’s LVM3 launch vehicle is scheduled to lift off the CMS-03 communication satellite in its 5th operational flight (LVM3-M5) today (November 02, 2025).
