The Geosynchronous Satellite Launch Vehicle Mark III is a launch vehicle developed by the Indian Space Research Organization (ISRO). It is intended to launch satellites into geostationary orbit and as a launcher for an Indian crew vehicle. The GSLV-III features an Indian cryogenic third stage and a higher payload capacity than the current GSLV.

Whole World eyes were set at the launch of ISRO’s heaviest rocket on June 5, 2017, and it was successfully launched. The 640-ton GSLV Mk III rocket is carrying a satellite weighing more than three tons into a high orbit above Earth.

Here are 10 things to know about the GSLV MkIII-D1 mission:

  1. The 43-meter (140-foot) GSLV MkIII-D1 rocket was launched from the Second Launch Pad at SDSC SHAR, Sriharikota in Andhra Pradesh.
  2. Dubbed ‘Monster Rocket’ by scientists, it is India’s most powerful homegrown rocket to date to be launched from our own soil and weighs as much as 200 fully grown elephants or five fully-loaded Boeing Jumbo Jets.
  3. The GSLV Mk III D1 is a three-stage vehicle with indigenous cryogenic upper stage engine designed to carry heavier communication satellites into the Geosynchronous Transfer Orbit (GTO).
  4. The GSLV Mk III D1 is capable of lifting payloads of up to 4,000 kg into the Geosynchronous Transfer Orbit (GTO) and 10,000 kg into the Low Earth Orbit.
  5. GSAT-19 satellite the heaviest satellite made and to be launched from India and is a voluminous animal and it will be launched using GSLV Mk III.
  6. GSAT-19 is going to be powered for the first time with indigenously-made Lithium-ion batteries. These batteries have been made so that India’s self-reliance quotient can increase. In addition, similar batteries can then be used to power electric vehicles like cars and buses.
  7. A successful launch of the 640-tonne rocket will be another feather in the cap for ISRO.
  8. Scientists say the rocket, developed over 15 years at a cost of Rs 300 crore.
  9. Till date, India had to depend on foreign launchers for communication satellites weighing more than 2,300 kg.
  10. The GSLV MkIII was earlier known as Launch Vehicle Mark-III or LMV Mark III – If it successfully clears tests –then it could be India’s first vehicle to ferry people into space.
