Why in the news?

Indian heavy lift rocket Launch Vehicle Mark 3 (LVM 3) successfully carried 36 satellites weighing a total of 5.8 tonnes to outer space. The rocket took off from the launch pad at the Satish Dhawan Space Centre in Sriharikota.

About OneWeb Gen-1

OneWeb is a network providing worldwide communication connectivity, utilizing a constellation of satellites in Low Earth Orbit (LEO) to achieve this goal. A major investor and shareholder in OneWeb are India’s Bharti Enterprises. The current launch marks the 18th for OneWeb, and the third for this year, bringing the total number of satellites in its constellation to 618. This launch is a significant milestone for the company, as it marks the first time an LEO operator has achieved the number of satellites necessary for global service. OneWeb is now poised to commence its global coverage shortly.

About Launch Vehicle Mark 3 (LVM3)

LVM3 is a three-stage vehicle with two solid strap-on motors, one liquid core stage (L110), and a cryogenic upper stage (C25).

Significance of Launch Vehicle Mk 3

It is also known as GSLV Mk III (Geosynchronous Satellite Launch Vehicle Mark III) and is a significant achievement for India’s space program. Here are some of the reasons why:

  • Heavy lift capability: Launch Vehicle Mark 3 (LVM3) is the heaviest and most powerful rocket that India has ever built. With a lift-off weight of 640 tons, it can carry payloads up to 4,000 kg to Geosynchronous Transfer Orbit (GTO) and up to 10,000 kg to Low Earth Orbit (LEO). This heavy lift capability makes it an essential tool for launching large satellites and missions to the Moon and Mars.
  • Indigenous technology: The development of LVM3 represents a significant achievement for India’s space program because it relies on indigenous technology. The rocket uses an entirely new cryogenic engine that was developed in India, making India one of the few countries in the world to have the technology to build and launch cryogenic engines.
  • Reduced dependency on foreign launch vehicles: Before the development of Launch Vehicle Mark 3 (LVM3), India was dependent on foreign launch vehicles to launch its heaviest satellites. Now, with the capability to launch heavier payloads using indigenous technology, India has reduced its dependence on foreign launch vehicles.
  • Strategic importance: LVM3 has strategic importance for India’s defense and communication needs. It can help India to launch advanced surveillance and communication satellites, which are critical for national security and defense.
