The Indian Space Research Organization (ISRO) is preparing for three upcoming space flight missions this year. The first launch of the CMS-03 communications satellite with its LVM3 vehicle will take place in a few days while the other two are scheduled for December.
Strategic communications satellite LVM3-M5, designed primarily to serve the Indian Navy, will fly on November 2. The fifth operational satellite in the series will replace the GSAT-7 satellite launched in 2013.
ISRO Spaceflight said in a post on X, “𝗗𝗲𝗰𝗲𝗺𝗯𝗲𝗿!! ISRO plans to launch the PSLV-C62 mission in mid/late December, which will be a comeback flight for PSLV after the failure in its previous mission.
Announcing the dates of upcoming space missions, it said, “Upcoming launches for ISRO in 2025 –
• LVM3-M5 》2 November
• LVM3-M6 》First week of December
• PSLV-C62 》mid/end December》
LVM3-M5
According to ISRO, the CMS-03 multi-band communication satellite will provide services over a wide maritime area including the Indian landmass. Weighing approximately 4,400 kg, CMS-03 will become the heaviest communication satellite ever launched by ISRO.
Talking about its upcoming spaceflight mission, ISRO said in a statement, “India’s LVM3 launch vehicle is scheduled to launch CMS-03 communication satellite in its 5th operational flight (LVM3-M5) on November 02, 2025. CMS-03 is a multi-band communication satellite that will provide services over a wide maritime area including the Indian landmass.”
It will be launched into Geosynchronous Transfer Orbit (GTO) from the second launch pad of Satish Dhawan Space Center (SDSC) in Sriharikota at 5:26 pm on Sunday. On October 26, the launch vehicle was transported to the launch pad after being fully assembled and integrated with the spacecraft.
LVM3-M6
LVM3-M6, the sixth operational mission of the LVM3 launch vehicle, is scheduled to launch in the first week of December, featuring the CE20 cryogenic engine.
“On March 14, 2025, ISRO successfully conducted flight acceptance hot testing of the cryogenic engine identified for the sixth operational mission of the LVM3 launch vehicle (LVM-M6) at ISRO Propulsion Complex (IPRC), Mahendragiri. Cryogenic engines for every mission undergo hot testing as part of their acceptance for flight,” ISRO said.
PSLV-C62
Months after the failure of Polar Satellite Launch Vehicle (PSLV) C61, ISRO is set to launch PSLV-C62 soon. The mission, launched on 18 May 2025 carrying the seventh satellite of ISRO’s RISAT series, was the 63rd flight of PSLV. Using the 27th PSLV-XL configuration satellite was expected to boost India’s space surveillance capabilities and contribute to better governance and faster disaster response.
PSLV-C62, which was scheduled to launch in September or October this year, will launch in mid or late December.
