    ISRO is doing much better then other govt. entities in R&D. We will get there slowly. I am sure GSLV mk4 or the improved GSLV MK3 will have better payload capacity.

    Better to think over it again or you guys don't even read anything about those.
    Nothing like GSLV Mk4 exists. GSLV Mk3 is the last (at least the biggest) rocket of this series. It's just an experimental rocket to demonstrate technologies for future launchers. The only succesors here are PSLV HP and PSLV 3S.
    Rest, everything is to be replaced with expandable rockets.
    Next is Series ULV, followed by HLVs, with higher capacity, designs of these vehicles are very identical to GSLV Mk3 though.

    Must be near as that of Ariane-5 or it can has an efficiency near to Ukrainian Zenith.
    But we won't have to wait for very long. Work on TLP is yet on hold before configuration of HLV family is decided. Once it's done, we can get the info from DOS documents or in space expo next year.

    One reason is that we are using low energy low cost fuel to save cost. If we use NEPE like fuel, we may increase the efficiency of the rocket but cost will surge. Secondly,ISRO has made low weight motors, pumps from alternate material. If we use that than we can increase load by a very good margin. However they are costly. Price will go up if we try to improve the efficiency of the vehicle.

    we just need high energy fuel and more use of semi cryo engines. If we put semicryo engine into GSLV MK3, we may go beyond 6 ton and may reach upto 8 tons once the rockets are developed.

    January 20th, assembly already started if I'm not wrong.
    [​IMG]
    Followed by PSLV C-37 on 27th January.
    If ISRO can conduct two consecutive launches in 7 days, it will break it's own record of 18 days between PSLV C-35 and GSLV F05.

    ISRO to launch 103 satellites in the year 2017 (in a single launch)
    P. Kunhi Krishnan said success of every mission is important to them and expressed confidence in achieving more mile stones in 2017.
    [​IMG]The first launch for the year is going to be PSLV-C37 with a whopping 103 satellites including Cartosat-2D in January 27.
    So, it's 103 now instead of 83.:D
    @PARIKRAMA @Gessler
    GSLV Mk3 has been pushed to March though.
