Weighing 6,100 kg, the communication satellite would be the heaviest payload to be placed into the Low Earth Orbit (LEO) in LVM3 launch history from Indian soil.
The Indian Space Research Organisation (ISRO) on Saturday said it has successfully conducted the flight acceptance hot testing of the cryogenic engine identified for the sixth operational mission of LVM3 launch vehicle (LVM-M6) at ISRO Propulsion Complex, Mahendragiri in Tamil Nadu.
ISRO stated that the disengagement of at least one contact -- in both the main and redundant paths -- of a connector led to the failure of NVS-02.
ISRO is set to launch its communication satellite CMS-03 from Sriharikota. The satellite, weighing 4,410 kg, will be the heaviest launched from Indian soil into a Geosynchronous Transfer Orbit (GTO).
The heaviest communication satellite to be launched from the Indian soil onboard a new generation, homegrown 'Bahubali' rocket was successfully placed into the intended orbit on Sunday, the Indian Space Research Organisation said.
Kwatra termed India's successful launch of an American communication satellite on Wednesday as a 'very important and big day' for partnership between Washington and New Delhi, saying it caps a series of achievements in 2025 in bilateral space cooperation between the countries.
Indian Space Research Organisation scientists have carried out a new experiment on the indigenously developed C25 cryogenic stage of the LVM3-M5 rocket which successfully placed the Communication Satellite CMS-03 into the intended orbit on Sunday, said its Chairman V Narayanan.
The satellite, weighing about 4,410 kg will be the heaviest to be launched from the Indian soil and into a Geosynchronous Transfer Orbit (GTO), the space agency said. The satellite will travel onboard a LVM3-M5 rocket, dubbed as 'Bahubali' for its heavylift capability.
ISRO is developing a third launch pad at Shriharikota to accommodate heavier satellites and next-generation launch vehicles. The new facility will support both crewed and uncrewed missions.
These upcoming launches carry added significance in light of setbacks suffered in recent years.
ISRO has announced plans for seven launch missions by March, including the first uncrewed mission for the Gaganyaan project and demonstrations of new satellite technologies.
India is set to take its first steps towards its own human space flight when the uncrewed Gaganyaan mission soars to the skies later this year. Private players in the space sector are also gearing up for launching satellites on home-built rockets.
From a surge in startups to crewed mission preparations, 2025 marks a transformative year as India eyes $44 billion space economy by 2033.
ISRO chairman announces plans for nine major launches by the end of the fiscal year, including the Blue Bird Block2 communication satellite for the US in collaboration with NASA.
The ISRO on Sunday scripted yet another history after its LVM3 rocket successfully placed 36 satellites of United Kingdom-based OneWeb group company into intended orbits.
Indian Space Research Organisation's (ISRO's) heaviest rocket LVM3 will launch British start-up OneWeb's 36 broadband satellites from the spaceport in Andhra Pradesh's Sriharikota on October 23, marking the launcher's entry into the global commercial launch service market.
The mission is targeted for launch in the fourth quarter of 2024.
'The LVM3 rocket will orbit one Block 2 BlueBird satellite in Low Earth Orbit.'
The Indian Space Research Organisation (ISRO) on Thursday announced that its lunar mission Chandrayaan-3 will be launched on July 14 from the space port at Sriharikota in Andhra Pradesh.
The Human-rated LVM3 vehicle, the Crew Escape System and the Crew Module and Service Module are all in final stages of testing and integration.
The Indian government has approved the construction of a third launch pad at Sriharikota, capable of sending heavier spacecraft into orbit. This new facility will support India's ambitious space program, including the Gaganyaan human spaceflight mission and a lunar landing. The launch pad will be built at the Satish Dhawan Space Centre and is expected to be operational within four years.
Indian astronaut Shubhanshu Shukla and three others are expected to travel to the International Space Station on June 19, after SpaceX successfully resolved the liquid oxygen leak in its Falcon-9 rocket, the Indian Space Research Organisation (ISRO) announced on Saturday.
Narayanan has a long and distinguished career at ISRO, having played a key role in several important missions, including Chandrayaan-2 and 3, and the Gaganyaan programme.
Chandrayaan-4 will involve at least two separate launches of the heavylift LVM-3 rocket that will carry five different components of the mission which will be assembled in orbit.
The fuel cost will come down if rockets are launched from Kulasekarapattinam as they will have a straight trajectory and need not have to avoid Sri Lanka, which is being done by rockets flown from Sriharikota.
'The work is already on with various data being studied.'
Rigorous testing demonstrates the engine's mettle, it said, adding the CE20 engine identified for the first uncrewed flight LVM3 G1 also went through acceptance tests.
For the Gaganyaan programme, LVM3 rocket is re-configured to meet the human rating requirements and has been christened as 'Human Rated LVM3', ISRO said and it would be capable of launching the Orbital Module to an Low Earth Orbit of 400kms.
ISRO is part of an exclusive league which has forayed into the Moon and Sun.
The cryogenic upper stage of the LVM3 M4 launch vehicle, which successfully injected the Chandrayaan-3 spacecraft into the intended orbit on July 14 this year, made an uncontrolled re-entry into the Earth's atmosphere, the ISRO said.
At 6.23 am on 29.1.2025, the 50.9 metre tall and weighing 420.7 ton Geosynchronous Satellite Launch Vehicle-F15 (GSLV-F15) is slated to blast off from the second launch pad carrying the 2,250 kg NVS-02 navigation satellite.
A number of private companies have contributed to the development of ISRO's Chandrayaan-3 spacecraft which successfully landed near the south pole of the Moon on Wednesday evening.
The Indian Space Research Organisation successfully launched its 100th mission on Wednesday, with a GSLV rocket carrying navigation satellite NVS-02.
The soft landing of the spacecraft is planned for late August. The mission is expected to be supportive to future interplanetary missions.
In a boost to the space programme, the government on Wednesday approved the Chandrayaan-4 mission to bring back moon rocks to earth, to send a spacecraft to orbit planet Venus and to expand the Gaganyaan project to build an Indian space station.
On Friday, July 14, India launched its ambitious third lunar mission Chandrayaan 3, eyeing a rare feat in moon exploration.
A team of Indian Space Research Organisation scientists on July 13 visited the Tirupati Venkatachalapathy temple ahead of Friday's much anticipated Chandrayaan-3 launch.
The Indian Space Research Organisation (ISRO) is all set to make its maiden commercial launch of 36 broadband communication satellites on board the space agency's heaviest rocket LVM3-M2, the countdown for which began early on Saturday at Sriharikota spaceport in Andhra Pradesh.
The engine is earmarked for the LVM3-M3 mission identified for launching the next 36 OneWeb India-1 satellites, the Indian Space Research Organisation said.
The heaviest rocket of the Indian Space Research Organisation -- LVM3-M2/OneWeb India-1 -- blasted off from the Sriharikota spaceport on Sunday to place 36 broadband communication satellites into the Low Earth Orbit (LEO) for a UK-based customer.
