    Finally they did it !!!

    From the velocity plot it does seem that the C27 stage has more juice. Next step is to realize it's full potential, 4-4.5 tonnes to GTO.

    C25 thrust was better than predicted. Slight deviation seen on graph.

    As @Agent_47 said, you can see the increased velocity in this graph (green line on top going above & beyond the white nominal line) -

    This is a good indication as it shows there is much more untapped potential with the C25's performance - it leaves more room for future upgrades/payload optimization. It's possible that with this being the first real launch of Mk.III with actual C25 stage, ISRO may have reduced the margins a bit to stay on the safe side.

    Thanks ..... I didnot see that graph ...... :biggthumpup:

    Also why is that there is an initial altitude loss during cryo stage ??

    AFAIK, the dive is necessary in order to attain the additional velocity/altitude in the final stage (before separating the satellite). As you can see, the dive is followed by a sharp rise.

    Cryo engine cutoff happened 20seconds earlier than nominal.

    Modi says its a "step forward for higher capabilities". Looks like ISRO will be leapfrogging with upgrades and innovations
