Why in the news
- ISRO has successfully launched the LVM3 M2/OneWeb India-1 mission.
- This rocket carried almost 6 tonnes of payload into the lower earth orbit, the heaviest ISRO mission till now.
LVM3-M2/One Web India-1
- This mission is a dedicated commercial satellite mission of New Space India Ltd (NSIL).
- This mission is a Central Public Sector Enterprise (CPSE) under the Department of Space, Government of India.
- OneWeb is a joint venture between the UK government and India’s Bharti Global.
- Lift vehicle–GSLV MkIII was renamed for this mission as Launch Vehicle Mark-3 (LVM3-M2).
- It is a three-stage rocket with the
1st stage fired by solid fuel,
Followed by 2nd stage of liquid fuel
The 3rd stage is the cryogenic engine.
- LVM3-M2 of 36 satellites belonging to Network Access Associated Ltd (OneWeb).
- The mission includes the separation of all 36 satellites into 601 km orbit with a minimum 137 m distance between any payload satellites.
- It is the 1st Indian rocket with a six-ton payload.
- It is the 1st launch of LVM3 to LEO.

- This mission will make the company cable start offering satellite broadband services across the country by 2023.
- This mission will provide high-speed internet services in remote areas also, where terrestrial networks are difficult to set up, including the middle of the ocean, the Himalayas (even on top of Mount Everest)
- It will be capable of handling multiple satellite separation events.
- It will increase the nominal mission duration.
- It will also ensure a safe separation distance through C25 (Cyro ) stage re-orientation and will increase the velocity.
- It will also check the data availability data duration of the entire mission.
- Recognition of new payload adaptor and interface ring for the satellites dispenser
- It operates in LEO Polar Orbit Satellites; these satellites are arranged in 12 rings (Orbital planes) with 49 satellites in each plane.
- The one web constellation orbital planes are inclined to be near polar (87.9 Deg.)
- These orbital planes will be 1200 km above the Earth.
- Each and every satellite completes a full trip around the earth every 109 minutes.

About New Space India Ltd (NSIL):
- It is Headquartered in Bengaluru
- It is a Central Public Sector Enterprise of the Indian government.
- Under the administrative control of the Department of Space, it was set up in 2019.
- This is considered the commercial arm of the Indian Space Research Organization (ISRO) with the chief responsibility to empower Indian industries to take up high-technology space-related activities.
- The objectives
- Owning satellites for Earth Observation and Communication applications and providing space-based services
- Contractions of satellites and launching them as per customer.
- Accommodating the Launch Services for satellites belonging to the customer.
- Constructing the launches vehicles through Indian Industry and launching as per the requirement of the satellite customer
- It will provide space-related Services which are related to Earth Observation and Communication satellites on a commercial basis.
- It will construct the satellite through Indian Industry
- Technology will transfer to Indian Industry
Other Launch Vehicles Developed by ISRO
Satellite Launch Vehicle (SLV):
- The 1st rocket was developed by ISRO.
- It was simply named an SLV, or Satellite Launch Vehicle.
Augmented Satellite Launch Vehicle (ASLV):
- ASLV and SLV both can carry small satellites, measuring weight up to 150 kg, to lower earth orbits.
- Till the 1900s ASLV operated before PSLV came into operation.
Polar Satellite Launch Vehicle (PSLV):
- It was 1st launched in 1994, and since then it is ISRO’s main rocket.
- At present PSLV, it is improved in many ways and is many times more powerful than the ones used in the 1990s.
- It is the 1st Indian launch vehicle to be equipped with liquid stages.
- It is considered the most reliable rocket used by ISRO till now, with 52 of its 54 flights being successful.
- It successfully launched two spacecraft – Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft in 2013 – that later traveled to Moon and Mars respectively.
Geosynchronous Satellite Launch Vehicle (GSLV):
- This rocket of ISRO is substantially more powerful, it is designed to carry heavier satellites much deeper into space. Till today, GSLV rockets have carried out 18 missions, of which only 4 were failures.
- It is considered taking 10,000 kg of satellites to lower the earth’s orbits.
- India’s own developed Cryogenic Upper Stage (CUS), forms the 3rd stage of GSLV Mk II.
- Mk-III versions empowered ISRO to launch its satellites self-sufficiently.
- Prior to this, India used to depend on the European Arianne launch vehicle, to carry its heavier satellites into space.
- Chandrayaan -2 mission to the moon in 2019 was carried out in the GSLV Mark-III, it was the 1st operational flight of the rocket
- ISRO changed the name of GSLV Mark-III to Launch Vehicle Mark-III.
- A GSLV for the Geostationary Orbit (GEO) will continue to be called so.
- The LVM3 will go everywhere such as GEO, Medium Earth orbit (MEO), LEO, and missions to the moon, and sun.
