The Indian Space Research Organisation (ISRO) will flight-test the Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), its heaviest rocket so far, on an experimental flight next year.
The first of the heavy-duty rockets is expected to take to the sky next January on an experimental flight whose later versions could be used to send humans on space missions, ISRO said.
The Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), a launch vehicle currently under development by the ISRO, would be used to put in orbit heavier communication satellites weighing up to five tones and pack more transponders.
It would also enhance the capability of the country to be a competitive player in the multimillion dollar commercial launch market. The vehicle envisages multi-mission launch capability for GTO, LEO, Polar and intermediate circular orbits, ISRO said in a web site release.
GSLV-Mk III is designed to be a three-stage vehicle, with a height of 42.4 metres and a lift off weight of 630 tonnes.
The first stage comprises two identical S200 large solid booster that uses 200 tonne solid propellant that are strapped on to the second stage, the L110 re-startable liquid stage. The third stage is the C25 LOX/LH2 cryo stage. The large payload fairing measures 5 m in diameter and can accommodate a payload volume of 100 cu m.

The Indian Space Research Organisation (ISRO) will make a fresh attempt at launching the Geosynchronous Satellite Launch Vehicle (GSLV), the last two flights of which have ended in failure, in July this year, ISRO chairman K Radhakrishnan said on Tuesday.
The GSLV will carry a communication satellite GSAT-14 to be put into the space.
GSLV is the second satellite launch vehicle developed by ISRO, the other one being PSLV, or Polar Satellite Launch Vehicle, which has just completed the 22nd successful launch in a row. The GSLV has been less lucky, with four of its 10 attempted flights, ending in failure.
“GSLV is an excellent vehicle, a beautiful vehicle. As compared to the PSLV, it is much less complex, except for one stage. It is far simpler to handle, though it has a large number of control components,” Radhakrishnan said at a public lecture at the Indian National Science Academy.
The GSLV to be launched in July will be run on an indigenous cryogenic engine. Its assembly has started at Sriharikota facility on January 31, Radhakrishnan said. The cryogenic stage is being integrated and one more test is planned to be conducted later this month.
Radhakrishnan said the next generation of the GSLV, called GSLV-Mark III, which is expected to revolutionise India’s space capabilities, would be launched in January next year. The GSLV-Mk III would be the heaviest Indian rocket to fly off, and would be capable of putting large satellites, weighing up to 5 tonne, into space.[Either it is a typo or the 5 ton payload is wrt to SSO. According de website of ISRO, MkIII can carry upto 4 tons to GTO] The present GSLV can carry up to 2.5 tonne.
GSLV-Mk III is also planned to be used for human space flights in future. “We are targeting an experimental flight of the GSLV-Mk III in January. Further development will happen after that,” Radhakrishnan said.
The project director of GSLV-Mk III, S Somnath, said simulation of the flight were being done. “But there are certain tests that cannot be performed on the ground. So an experimental launch is required,” he said.

ISRO planning first privately built PSLV launch in 5 years
Moving forward on its plans to rope in the industry in its activities, ISRO is looking towards the launch of the first privately built rocket in the next five years.
The Indian Space Research Organisation has embarked on hiving off production of communication satellites and polar satellite launch vehicles (PSLVs) to the industry.
“We are now setting up a national committee to work out the modalities on how to go about it,” ISRO Chairman K Radhakrishnan told PTI when asked about the agency’s plans to rope in the industry for producing PSLVs and communication satellites.
He said the space agency had told the industry representatives at a meeting in Ahmedabad in January that it was looking at PSLVs and communication satellites produced by them.
“My target is five years from now on. Five years from now the first PSLV will roll out from that entity,” Radhakrishnan said.
He said the proposed national committee would look at various steps in this regard including the revenue model, technology transfer and related matters.
The space agency is keen to focus on unique science projects, develop remote sensing satellites and do more research and development instead of engaging in the repititive exercise of building communication satellites and launch vehicles.
The industry participation in development of communication satellites is upto 80 per cent. If satellites and launch vehicles can be produced by industry players, ISRO scientists will be able to concentrate on research-oriented activities, and have greater involvement of academic institutions.

ISRO Tests Human Spaceflight Program (HSP) Crew Module (CM) in Plasma Wind Tunnel
April 10, 2013, (Sawfnews.com) - ISRO recently conducted a Plasma wind tunnel test on a 1:28 scaled model of the Human Spaceflight Program (HSP) Crew Module (CM).
The test was conducted at the 6 MW high enthalpy facility at VSSC to check the performance and evaluate the erosion characteristics of the Thermal Protection System (TPS) material of the CM.
The CM would encounter temperatures in the range of 6,000 K to 10,000 K during re-entry. At such temperatures, the air gets dissociated and ionised and gets into a hyper reactive state.
Light weight, high performance TPS is employed to protect the vehicle in such a hostile environment.
The Plasma wind tunnel facility simulates the re-entry thermal regimes for the qualification of TPS.
In the PWT facility, an air stream is converted into plasma at temperature ranging from 8,000 K to 10,000 K. Scaled down models of the TPS are exposed to the plasma stream in the test chamber, where pressure corresponding to the altitude also is simulated. The performance of the TPS in the simulated re-entry conditions is evaluated.

just making a correction: the LVM3-X mission that is supposed to take place in jan 2014, ISRO will be using a passive cryo engine with liquid nitrogen to simulate real engine weight. The experimenter wont involve testing the CE20 engine. it is only to collect data of LVM3 journey through the atmosphere.

ISRO Conducts Functional Qualification Test of GSLV Mk-3 S200 Separation System
April 17, 2013, (Sawfnews.com) - ISRO is making steady progress towards the debut launch in April 2014 of its GSLV Mk-3 launcher, which will be capable of inserting a 10 ton spacecraft in low earth orbit.
It recently tested the separation system of the S200 strap on motors of the launchers from the core vehicle.
The first stage of the GLSV Mk-3 consists of two 200 ton, S200 solid rocket motors, strapped around the 110 ton restartable core liquid propellant second stage (L-110) using two Vikas engines.
The separation system consists of two joints viz fore end joint and aft end joint, which attaches the L110 stage of the core with S200 motors. The thrust developed by the S200 motors are transferred to the core vehicle through the fore end joint while the aft joint takes care of the lateral loads.
The S200 separation system is used to dump the two spent S200 motors at about 145 seconds after take off allowing the second stage to kick in.
The third stage of the GSLV Mk-3 would be an ISRO developed cryogenic rocket motor with a propellant loading of 25 ton (C-25).
The first flight of the Mk-3 will be a sub-orbital flight test, sans the cryogenic third stage.
