< warm>ISRO BlueBird Block-2 set in motion unrecorded: The last countdown for the launch of the LVM3-M6 rocket, which will carry the BlueBird Block-2 spacecraft, a new-generation US communication satellite, has begun.
The Indian Space Research Organisation (ISRO) BlueBird Block-2 spacecraft is scheduled to launch at 8.54 AM IST from the second launch pad at Andhra Pradesh's Sriharikota spaceport on Wednesday, December 24. The Live streaming for the event began at 8:25 AM.
After a flight of about 15 minutes from liftoff, the Bluebird Block-2 satellite is expected to separate from the launch vehicle.
The ISRO said that this historic mission would deploy the next-generation communication satellite designed to provide high-speed cellular broadband directly to smartphones worldwide.
The ISRO’s heavy-lift Launch Vehicle Mark-3 (LVM3-M6) was launched at 8.55am, after a brief 90 seconds delay.
According to an NDTV report, the delay was caused due to a possible space debris conjunction along the flight path.
The report claimed that ISRO detected a potential risk of collision involving debris or another satellite passing through the rocket’s trajectory.
In a post on X, ISRO confirmed the revised schedule, stating, “Launch Day for #LVM3M6. LVM3-M6 lifts off today at 08:55:30 IST with BlueBird Block-2 from SDSC SHAR."
After a flight journey of about 15 minutes, the spacecraft BlueBird Block-2 riding piggyback on the rocket, is expected to get separated and reach its intended orbit at an altitude of about 520 km, ISRO said.
ISRO's heaviest rocket LVM3-M6 is 43.5 metre tall, supported by two S200 solid boosters lifted off majestically at 8.55 am from the second launch pad at this spaceport, situated about 135 km east of Chennai.
The LVM3-M6 rocket is carrying a next-generation US communication satellite BlueBird Block-2.
BlueBird Block-2 mission is part of the global LEO (Low Earth Orbit) constellation to provide direct-to-mobile connectivity through satellite.
This constellation would enable 4G and 5G voice and video calls, texts, streaming and data for everyone, everywhere at all times. It features a 223m2 phased array, making it the largest commercial communications satellite ever deployed into Low Earth Orbit, about 600 km altitude by ISRO.
