ISRO makes history, its heaviest rocket LVM3-M2 successfully placed all 36 satellites

Indian Space Research Organisations’ heaviest LVM3-M2 rocket successfully placed 36 UK-based customer broadband communications satellites into their intended orbit on its first commercial mission on Sunday, the space agency said, describing the mission as “historic”. OneWeb Ltd is a UK customer of NewSpace India Ltd (NSIL), the commercial arm of ISRO and a global space-powered communications network enabling internet connectivity for governments and businesses. Bharti Enterprises is one of the main investors in OneWeb.

With Sunday’s success, ISRO averted the anomaly it experienced during its SSLV (Small Satellite Launch Vehicle) mission on August 7, which rendered the satellites unusable.

Early on Sunday, a beaming ISRO chairman S Somanath announced that Deepavali has started early for the space agency’s scientists.

“LMV3 M2/OneWeb India-1 mission successfully completed. All 36 satellites placed in intended orbits. @NSIL_India @OneWeb,” ISRO said in a tweet minutes after Somanath announced that 16 satellites had been placed in desired orbits . while the rest would take some more time.


All 36 satellites were injected into orbit about 75 minutes after the rocket lifted off from the spaceport here.

Addressing a gathering at the Mission Control Centre, Somanath said the festival celebrations began at the Satish Dhawan Space Center when LVM3 and its very first commercial mission achieved the orbit very precisely.

“Now the rocket has entered the orbit, 16 satellites out of 36 satellites have already been injected. I wanted to tell you that it is a slow process of separating the satellites. The data about the separation of the remaining 20 satellites will come.” a little later and the observation missions of this department continue,” he said earlier. ISRO later confirmed that the desired objective of the mission was achieved.

Former ISRO chiefs K Sivan and AS Kiran Kumar and Bharti Enterprises founder and chairman Sunil Mittal, among others, witnessed the launch from the mission control centre.

Terming the mission as “historic”, Somanath, also a minister, the space ministry credited Prime Minister Narendra Modi’s support for the success of the mission.

“Congratulations to the entire launch vehicle team for taking the opportunity to prepare for a historic mission today. I would also like to thank the OneWeb team for trusting us to host LVM3…We very much hope that the next LVM3 mission will do the same to accommodate the remaining 36 satellites contracted by NSIL,” he said.

Completing the ISRO team for the ‘laudable’ LVM3 mission, NSIL Chairman and Managing Director D Radhakrishnan said, “The three major stakeholders of this particular mission, NSIL, ISRO and OneWeb India, have shown the world how to contract and execute missions in less than 3 -4 month.”

Earlier, at the end of the 24-hour countdown, the 43.5-metre rocket took off majestically at the preset time at 07:07 on Sunday from the second launch pad at the Satish Dhawan Space Center here.

The vehicle is also referred to as one of the heaviest for its ability to carry satellites weighing up to 8,000 kg.

The entire mission to place the 36 satellites took about 75 minutes from liftoff, as scientists had to shut down the engine to place the satellites in their orbits.

Sunday’s mission marks several key milestones, as the LVM3-M2 mission is the first dedicated commercial launch vehicle mission.

According to ISRO, the vehicle carried the heaviest payload with 36 OneWeb satellites and became India’s first rocket with a payload of 5,796 kg.

Mission Director Thaddeus Baskar said, “The mission was a requirement given to this team by the Chairman of ISRO to execute the mission in a very short time, in less than three months.”

“Once the requirement was defined, the entire ISRO team seized the opportunity and worked with full vigor. There was no room for sleep during the whole plan and everything has to be done right the first time,” he said.

The launch is also the first for LVM3-M2, which will place satellites in Low Earth Orbit (LEO – up to 1,200 km above Earth) as opposed to Geosynchronous Transfer Orbit (GTO).

ISRO scientists renamed the launch vehicle as LVM3-M2 from GSLV-Mk III as the latest rocket is capable of carrying 4,000 kilogram class satellites to GTO and 8,000 kg payload to LEO.

The LVM3-M2 mission would give the space agency a shot at a new launch vehicle set to put satellites into low Earth orbit, along with ISRO’s trusty Polar Satellite Launch Vehicle (PSLV).

The rocket is a three-stage launch vehicle consisting of two S200 solid propellant belts on the flanks and a core stage containing an L110 liquid stage and a C25 cryogenic stage.

OneWeb implements a constellation of 648 satellites in low Earth orbit. While 36 satellites were launched on Sunday, the next batch of satellites is expected to be placed into orbit in early 2023, ISRO said.
