The GSLV-Mk III-D1 launcher would carry GSAT-19 satellite which has a mass of 3,200 kg.

The Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), the heaviest rocket ever made by India and capable of carrying large payloads, is set for launch from the Satish Dhawan Space Centre in Sriharikota on June 5, 2017

  • Height: 43.43 metres
  • Vehicle Diameter: 4 metres
  • Number of stages: 3
  • Payload capacity (Lower orbit earth): 8,000 kg
  • Payload capacity (Geosynchronous Transfer Orbits): 4,000 kg
  • Satellite on board: GSAT-19
  • Weight of the satellite: 3,136 kg
  • Total lift-off mass of the rocket: 640 tons.

History and Developments 

  • ISRO launched the first GSLV satellite in 2001 with an initial payload capacity of 1,500 kg.
  • Later, the payload was upgraded to 1,900 kg with another version.
  • Nine years and five flights later, the second iteration of the series, GSLV Mark II, was introduced with a payload capacity of 2,200 kg. ISRO is still using GSLV Mark II.
  • A total of five Mark II flights have been undertaken, out of which four were successful. The last was the successful launch of the SAARC satellite on 5 May, 2017.
  • Work on Mark III began early in the millennium but there were many obstacles.
  • One key challenge was developing a homegrown cryogenics engine.
  • India wanted to import the engine from Russia all the way back in 1991 but pressure from the US had seen the deal bite the dust.
  • However, in 2014, India was able to launch a GSLV with an indigenous cryogenic engine.
  • Mark III’s first experimental flight was successfully performed on 18 December 2014.
  • A series of tests followed to ensure that the different stages of the rocket were working. As reported by TOI, the total project cost is estimated to be at ₹2,900 crore.

Technology Behind GSLV MK III

  • A cryogenic rocket engine uses liquid fuel stored at very low temperature. ISRO has developed an engine called CE-20 that uses liquid hydrogen at -253-degree celsius and liquid oxygen at -195-degree celsius.
  • Because of the low temperatures required, developing the engine is a challenging feat.
  • The height of the rocket’s upper stage is 25 metres and it carries 28 tons of cryo fuel.
  • The current engine has 20 tons of thrust as compared to 12 tons of thrust achieved previously.

Here are a few facts you need to know about the rocket.

  1. GSKV-Mk III  is capable of launching four-tonne satellites in the Geosynchronous Transfer Orbit (GTO).
  2. The rocket is also capable of placing up to eight tonnes in a Low Earth Orbit (LEO), enough to carry a manned module.
  3. GSLV-Mk III’s first developmental flight, D1, will carry on June 5  the GSAT-19 satellite — developed to help improve telecommunication and broadcasting areas.
  4. This is India’s first fully functional rocket to be tested with a cryogenic engine that uses liquid propellants — liquid oxygen and liquid hydrogen.
  5. It took about 25 years, 11 flights and over 200 tests on different components of the rocket for it to be fully realised.
  6. The 640-tonne rocket, equal to the weight of 200 fully-grown Asian elephants, is the country’s heaviest but shortest rocket with a height of 43 metre.
  7. GSLV-Mk III is a three-stage vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C-25).
  8. ISRO successfully conducted the static test of its largest solid booster S200 at the Satish Dhawan Space Centre (SDSC), Sriharikota on January 24, 2010. The successful test of S200, which forms the strap-on stage for the GSLV, makes it the third largest solid booster in the world. The static test of liquid core stage (L110) of GSLV-Mk III launch vehicle was done at ISRO’s Liquid Propulsion Systems Centre test facility as early as March 2010.
  9. C-25, the large cryogenic upper stage of the GSLV, is the most difficult component of the launch vehicle to be developed. ISRO successfully ground-tested the indigenously developed C-25 on February 18, 2017.
  10. If successful, the GSLV-Mk III — earlier named as Launch Vehicle Mark-3 or LVM-3 — could be India’s vehicle of choice to launch people into space.
