Massive changes in shape of payload fairing.
They look more aerodynamically shaped than last one.
I think this will improve payload capacity by certain amount.
Any one knowledgeable please give your insight.

GSLV Mk III
About the Launch Vehicle​

GSLV Mk III is a three-stage heavy lift launch vehicle developed by ISRO. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.

GSLV Mk III is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO), which is about twice the capability of GSLV Mk II.

The two strap-on motors of GSLV Mk III are located on either side of its core liquid booster. Designated as ‘S200’, each carries 205 tons of composite solid propellant and their ignition results in vehicle lift -off . S200s function for 140 seconds. During strap-ons functioning phase, the two clustered Vikas liquid Engines of L110 liquid core booster will ignite 114 sec after lift -off to further augment the thrust of the vehicle. These two engines continue to function after the separation of the strap-ons at about 140 seconds after lift -off.

The first experimental flight of LVM3, the LVM3-X/CARE mission lifted off from Sriharikota on December 18, 2014 and successfully tested the atmospheric phase of flight. Crew module Atmospheric Reentry Experiment was also carried out in this flight. The module reentered, deployed its parachutes as planned and splashed down in the Bay of Bengal.

GSLV-Mk III-D1 is the first developmental flight, carrying 3136 kg GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO).

Story of the Week
National Database for Emergency Management (NDEM) Version 3.0 Released

Government of India has envisaged a policy to build a safer and disaster resilient India by developing a holistic, integrated and proactive multi disaster and technology driven strategy for disaster management through collective efforts of all government agencies and non-government organisations.

Ministry of Home Affairs (MHA) has translated this approach into National Database for Emergency Management (NDEM), and entrusted the responsibility of implementing NDEM to Indian Space Research Organisation (ISRO), Department of Space for reducing the impact of natural and man-made disasters and providing timely information and decision-making tools in the event of disasters. National Remote Sensing Centre (NRSC), ISRO, Hyderabad is the lead agency to implement and operationalise NDEM project.

Accordingly, NDEM Version 1.0 was operationalised in 2013. Subsequently, NDEM Version 2.0 was launched in 2015 with improved features like multi-scale databases, decision-support tools and mobile apps with secured access. In addition, value added products such as flood inundation maps, forest fire hotspots, damage assessment maps, drought indices maps etc., are hosted on NDEM Portal for all major disaster events since 2013. The portal is also equipped with multi-resolution satellite imagery ranging from 5.8m to sub-metre. Currently, NDEM services are deployed for all 36 States/UTs with multi-institutional support from Central/State departments.

In order to enhance NDEM features and services, NDEM Version 3.0, a web enabled Geo-portal has been developed for emergency management. The objective of the portal is to serve the nation with a comprehensive multi-scale Geo-spatial database services coupled with set of decision support tools to assist the disaster managers during emergency situations.

The portal is browser independent and compatible to all computer devices and mobile phones with vector rendering services. The salient features of the NDEM Version 3.0 are:

• A dashboard for visualisation of disaster alerts, warnings issued by nodal departments, current disaster news and authorised social media content.

• Incident reporting through web and mobile apps.

• Integrated visualisation of multi-scale data services.

• Customised decision support tools such as proximity and optimal path analysis, report generation, etc., for relief management.

• Interactive tools for communication among State Government Departments and MHA through portal.

• Live audio/video module for visualisation of on-site response operations.

• Resource management module for allocation and monitoring of relief resources.

NDEM Version 3.0 portal was released recently by Hon'ble Home Minister Shri Rajnath Singh during the inaugural ceremony of 2nd meeting of National Platform on Disaster Risk Reduction (NPDRR) at Vigyan Bhavan, New Delhi on May 15, 2017.

Forget ICBM. With this, India would be only the forth country to have a rocket for human space exploration. With heavier payload, we could very much take step for deep space exploration along with space station. With this interplanetary mission would be much benefited.

 

[Indx TechStyle]

So what are all the advantages with this new launch ...?

Bigger share of space launch market and cutting down our own launch costs of comm. Sats.
We provide cheapest and acceptable launch services for light category, goes that high that we are able to have a fair share of launch market.

So, development of a cheap Mid Heavy and heavy launch service can put great heat on other launch market players.
Really great, we can pull others down to fraction till reusable launchers come.

what new developments we can expect with this new payload capabilities to india and also to ISRO ..

Demonstration of cryo tech for our heavy class rockets
Sending humans in space
And docking, so probably making a modular space station in near future

Weight limitation will be covered up now, so better and more extra terrestrial probes from India.

By any way this will help our future ICBM technologies or even payload capabilities ???

Little to do will that at least at this stage.

We had same base for ballistic missiles and rockets but now both have diverged ways.
But yes, PSLV-3S has something to do with ICBM.

Making ICBM doesn't need a rocket capable of going hundreds of millions of miles deep in space but miniaturizing and erecting the rocket in small modules. 12,000-16,000 kms ranges are enough to reach anywhere on planet.

 

[captscooby81]

would really love to see we put our man or woman on space ....And also find answer to that one question which is in mind for so many years ..Did the amerikan s really landed on moon or did they fooled the world .. Hope our moon lander find some details about ..And yaa our own ISS that would be awesome for some deep space research and find out more ...

More then something like ISS, I would be more thrilled if ISRO start building something like HST or JWST right now. We need to move forward from ASTROSAT.
@Indx TechStyle .

 

[captscooby81]

Hubble telescope wow the kind of images it used to take yes we need some in that area tooo explore deep far away space locations ...

Forget HST.... JWST is the next big thing. We too should start exploring in this field before aiming for SS. ASTROSAT already provided us a start. We should move forward with our thinking.

Other countries' spacecrafts including China have found the proofs of manned Moon landing by US.
Let's not mock reasonlessly.

And yaa our own ISS that would be awesome for some deep space research and find out more ...

Ya, that's all regarding exercising manned missions before landings on alien territories.
We have all building blocks for tech but problem comes here with priorities. Once, we get involved in Space Station tech & operations, annual space funding will have to be $5-6 billions at least against current $1.2 billions, much closer to Russia & PRC. May be, we can even become short of staff.

ASTROSAT-2 and Polix aka XPOSat in near future.
But for something like Hubble, we need at least 8-10 tonnes to GTO capacity (HLV) and an earlier a decade experience before making a giant.
For details & updates, I have a thread:
India's all Orbital Space Telescopes

 

[Chinmoy]

But for something like Hubble, we need at least 8-10 tonnes to GTO capacity (HLV) and an earlier a decade experience before making a giant.

Not necessarily. I have stated the point about HST and JWST keeping certain things in mind. As you have mentioned regarding the budget which has to be allocated to try something sort of SS, a ST would be a good stepping stone in this direction. Its not mandatory to haul up the whole thing at one go neither its mandatory to build up such a state of the art equipment at the very first go. In both this cases it could meet different objective.

Case 1- Modular approach towards the ST. This could help us to gain experience in module integration in space. SS is only possible by modular approach. So by taking a modular integration approach towards ST, we could have valuable experience before trying SS integration.

Case 2- Low level ST. Its a known fact that interest gets build through visual aspect. We cant expect to fulfill our shortfall in manpower in future if we can't generate interest towards space among our younger generation. The best way to do that is to present them the exotic images captured in the outer space. The sort of images now generated by ASTROSAT is good enough for intellects to work with. But just imagine the kind of excitement and thrill anyone experience while they get to see the color enhanced captures of galaxy and stars and cosmic cloud captured by HST now. These images are the ones which does feed the young mind and give us the blooming astronomers and astronauts of tomorrow. For that purpose one doesn't need a state of the art equipment like Hubble. Any small scale ST could achieve the same. Moreover ISRO should organize competition at school level for students to come out with ideas of visual space exploration..............


Hope I am not thinking too much in excitement... :biggrin2:
