    OMG. With virtually no experience in building commercial airliners let alone multirole fighters, how can the government even think of funding PSUs for a space shuttle programme?

    TR what makes you think that it will have humans, this programme is their for very long time and some of the rest have been done, like re entry. First test will happen this year or next year.

    I am sorry, this is a bit confusing. Is this showing two different ideas of reusable spacecraft? If so, the one on the left is more of a circus acrobatic than anything else.

    Pmaitra, these are two different things, look again it is Two stage vehicle, look at the model at the right
    [​IMG]

    It has two parts one is regular space shuttle (second stage), which is shown in right side of this image
    [​IMG]
    other one is motor which is first stage, since the ISRO wants its motor to be reuse when it is detach with the space shuttle type of vehicle, it lands on its legs, as they dont want to damage the motor.

    so it is two stage reusable vehicle.

    Why are you lot discussing about 2 year old thread ?

    Nothing happened as promised so far!!

    ISRO will join DRDO as failed organization if its next GSLV launch fails!! I really hope they succeed in next launch.

    Interesting post. Thank you for the explanation.

    I still have a few queries. Who exactly deploys the payload?

    The picture on top indicates the aeroplane or shuttle like vehicle is the second stage that deploys the payload and is in turn lifted by booster rocket(s). The picture on the bottom indicates that the shuttle like vehicle lifts the second stage which in turn deploys the payload.

    Obviously, at least to me, there are two ideas here:
    • Shuttle is Stage 1, Rocket is Stage 2
    • Rocket is Stage 1, Shuttle is Stage 2

    Yes Mr. Sayare, you are right. The Shuttle is the 2nd Stage and that makes complete sense.
