Re: Indian Space Program: News & Discussion - Sept 2016

While there was very heavy rain in some hill areas (Wynad), the story of monster rains all over, may not hold water.

Re: Indian Space Programme Discussion - Sept 2016

It should be noted that from the early 1980s the various candidate configurations for GSLV indicated a strong need for modular solid strap-on. Till 1984 no substantial progress was made in the design of the PSLV launch pad. An opportunity was available to build the facility which would cater to the...

Re: Indian Space Programme Discussion - Sept 2016

Yes. ISRO engine nomenclature generally reflects approx fuel in the stage in tonnes. All-up wt of stage thus is more, depending on MF. I think the mini Pslv will be: 1. Booster 60 tonne, 2.8m dia, 9m long (2 segments instead of 5 segments of current pslv S139) 2. Second stage ~24 tonne, 2.8m dia, 5...

Agni-V will be a 50-ton launcher. The thrust of the S200 engines will be too much for a 100 ton launcher. If a stage has to be modified to obtain the launcher, the easiest path would be to modify the S139 (first stage of PSLV) of the PSLV-3S config. Alternatively, substitute the first stage of the ...

This is very interesting. The PSLV-3s was proposed low-cost/low payload variant to lift 500-700 kg to LEO (2000 km?). It was to be achieved by removing the boosters and the second stage. Such a config would be around 200 Tons. This is something new. This is an even lighter version with an even ligh...

Re: GSLV-Mk III launch program/post-launch analysis

If ISRO comes with 2 more variations of LVM3, it can replace GSLV and PSLV

1. S139 * 2 + L120 + C7.5 - should get 2.5T to GTO
2. S60 * 2 + L120 + L2 - should get 1T to GTO

Since the HS is bigger in LVM3 it can handle more satellites in a single launch
