The Indian Space Research Organisation is developing new heavy lift launch vehicle (HLV) to carry future satellites, weighing up to 10 tonnes. Dr. M.C. Dathan, the director of Vikram Sarabhai Space Centre at Thiruvananthapuram informed that the upcoming scheduled test flight of GSLV MK3 in 2016 will be able to carry satellites up to 4 tonnes. However, the future satellites will weigh a minimum of about six tonnes and it's become necessary to design and develop heavy lift launch vehicle.

Dr. Dathan further informed that ISRO is taking a modular approach to develop the HLV. One of the ideas is to add a semi-cryogenic engine stage to the GSLV MK3 which will generate a total lift of about 6 tonnes. A more powerful upper cryo-stage will be required to generate an overall lift of about 10 tonnes. ISRO engineers are considering need-based, progressive development of the MK3 variants instead of a new rocket altogether every time.

ISRO-HLV

The innovation in technology related to circuit design and miniaturisation is leading to lighter weight satellites which require lesser lift to put them into orbit. This is why ISRO's adopting a modular approach. Dr. Dathan further informed that ISRO's also developing an orbiter, lander and rover for the upcoming Chandrayaan-2 mission. India second mission to the moon is planned in 2017.

We've seen a lot of action at ISRO in the recent times. We ISRO's talented engineers and scientists all the best for all the upcoming missions. We promise to keep our readers updated with the latest and the best from ISRO.

@Swapnil Suman • 01 Jun, 2015 • 2 likes A major milestone in the development of Indian Space Research Organisation (ISRO)’s next generation launch vehicle, GSLV MkIII, was achieved on successful long duration hot test (635 seconds) of high thrust cryogenic engine (CE20) on 28-04-2015 at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu. The CE20 cryogenic engine is being indigenously developed by ISRO to power the cryogenic stage of GSLV MkIII launch vehicle.
The completion of successful long duration hot test has once again proved ISRO’s capability in mastering the complex cryogenic technology. All subsystems of this engine such as Thrust Chamber, Injector, Gas Generator, LOX & LH2 Turbopumps, Control Components, Pyro systems etc., and the ground Test Facility systems performed very well and the parameters are well within the prediction.
A series of development tests on this engine are being carried out to validate the performance and to prove the design of the engine. Two cold start tests and four short duration hot tests were already carried out on this engine at IPRC, Mahendragiri.
