My understanding is that solid boosters are are heavy and inefficient, but at the same time are easier to store, provide huge thrust and are cheap. I don't know about the 'cheap' factor but it would be really useful to have a comparative table of launch costs per kg, as opposed to wright of...

They seem to have the labels the wrong way round. If GSLV III can lift 10 tonnes to GTO, then I would be a very happy man. Anyway, the main goal should be for India to be self sufficient in launching satellites and not worry about who can lift the most! or who can send humans to the moon. The...

GSLV Mk3 will give 4tons to GTO which is not significantly behind the Chinese. With hopefully the new ISRO semi-cryo engine now in testing stage we will get 6tons to to GTO in a couple of years hence matching the Chinese in terms of lift capacity.

I suspect your right about PR. ISRO maybe hoping to get a high publicity (which MOM is) success under its belt. MOM has already been a publicity success and the final icing on the cake will be insertion into Mars orbit in September. I think the risk of failure to Insert MOM is much lower than...

Agree entirely. We all prefer delays to disasters. Just wish we get proper information releases rather than random comments in newspapers.

Pretty lame blaming the delay on the Mars Orbiter Mission when MOM does not enter Mars orbit until late September. Reading between the lines seems like the crew module is causing the delay, which is a shame as the biggest benefit of the launch is to test the new 1st and 2nd stage rockets.

good to hear. although I don't get the logic of putting in an expensive new engine for the cryo stage but without any fuel!
