After several delays and a sub-orbital test flight on 18 December 2014, ISRO successfully conducted the first orbital test launch of GSLV Mk III on 5 June 2017 from the ISRO conducted the first static test of the L110 core stage at its Liquid Propulsion Systems Centre (LPSC) test facility at A second static fire test for the full in-flight duration of 640 seconds was completed on 17 February 2017.After the suborbital test flight of GSLV Mk III, modifications were made to the vehicle to improve performance. But that doesn’t mean we shouldn’t be proud of what ISRO's built. The total cost of a launch can go up to $220 mn, but most commercial launches are pegged at about $60 mn.In 2017, the Ariane 5 set a world record by launching a 10,865 kg payload to GTO. A heavier payload, where the boosters are not recovered, could cost about $150 mn.The Falcon Heavy has so far been launched only twice – the first took a Tesla Roadster to space. It’s also incredibly hard to develop, which is why only a handful of nations have succeeded in building one.The average cost of a GSLV launch is estimated to be about Rs 400 cr or $62 mn, making it one of the cheapest launch vehicles in the world.The biggest rival to ISRO’s GLSV Mk III is the Falcon 9 Full Thrust. It is bested by only Saturn V, the rocket that launched Apollo astronauts to the moon 50 years ago. If that wasn’t enough competition, SpaceX has managed to bring down the cost of each launch to a mere $50 mn, making it cheaper to launch than even the GSLV.The secret to that price is, of course, is the Falcon 9's reusable first stage, which returns to Earth under its own power after launch. The central stage will also separate once it runs through its fuel.Interestingly, the side cores are easier to recover than the central core because they separate at a much lower altitude and thus, require less energy to land. SpaceX’s Falcon Heavy is the most powerful launch vehicle in the world and the second most powerful rocket ever built. With its 4,000 kg of payload capacity the GSLV Mark III is yet another feather in ISRO's cap. It is this engine that allowed the PSLV to It develops a thrust of 200 kN in vacuum and can operate for 640 seconds. For fuel, it uses a mixture of oxygen and hydrogen, which are cooled to cryogenic temperatures (below -183ºC) and are thus in liquid form.A cryogenic engine is extremely efficient as compared to a regular rocket motor, making it ideal for spacecraft. These are all liquid-fuel engines.If it’s a true behemoth you seek, look no further than SpaceX’s Falcon Heavy. The Falcon 9 has has been launched 52 times to the GSLV’s three, and each of those missions was a success. Falcon Heavy. At an altitude of around 15 kilometres (9.3 mi), the module's apex cover separated and the parachutes were deployed. The S200 booster uses an The payload fairing has a diameter of 5 metres (16 ft) and a payload volume of 110 cubic metres (3,900 cu ft).The L110 core stage in GSLV Mk III is planned to be replaced by a As per a frame agreement for cooperation in the peaceful uses of outer space between India and Ukraine signed in 2005, Ukraine was expected to test components of the Indian version of the engine. Geosynchronous Satellite Launch Vehicle (GSLV) is an expendable launch system operated by the Indian Space Research Organisation (ISRO). Launch vehicles that are currently in development around the world What ISRO has developed with limited resources, limited cooperation from the world at large, strife from within, and a budget ($1.6 bn) that many space agencies would laugh at, is nothing short of enviable.The GSLV or Geosynchronous Satellite Launch Vehicle is classified as a Medium-Lift Launch Vehicle (MLLV) and is rated to carry a payload of 8,000 kg to LEO or Low Earth Orbit.
Even though GSLV Mk III shares the name, it is an entirely different launcher. Both missions were a success. ISRO downloaded launch telemetry during the ballistic coasting phase before the radio black-out to avoid data loss in the event of a splash-down failure.
And rather than carry a single, large engine, the Falcon 9 operates a total of 10 small engines.
