Momentous times for Indian Science and Technology..

Two momentous months for ISRO, August and September of 2016.

For any space mission, reducing the overall weight of the rocket / space vehicle (or substituting with lighter fuel, enabling heavier payloads to be carried aboard and developing higher thrusts with better technology is always and will always remain the highlights of all future space research.

The majestic GSLV Mk II with 2 strap on motors
Firstly, the great step, yesterday, ISRO has mastered cryogenic technology which besides providing 1.5 times thrust sends heavier payloads up to 2.5 T, to outer space (replacing heavy solid fuels) to geostationary orbits. 

The average speed for yesterday's 36,000 km journey of the 542 Tonne rocket with the satellite payload of 2.2 T, to geotsationary orbit ay 36,000 kms altitude took 17 minutes at velocity of 35.3 kms/sec (1,27,058 kmph).

The second feat was the air breathing rocket, scramjet, which besides on our Brahmos cruise missiles (at Mach 3, six times faster than the fastest US missile, Tomahawk), fuels our reusable launch vehicle, the Indian version of space Shuttle, which will bring down the cost of near earth (<100kms altitude) launches by 90%.

Feeling proud of ISRO and all friends working in that great organization.. 

Our Scientists and technologists are now showing that the scientists who did not ditch their motherland and stayed back are indeed far better than the worthless, opportunistic ones that migrated. 😊

Let us start believing in ourselves. We may have a lousy and a much-to-be-desired political and social systems in the country.

Let's be optimistic and hope the system would change for the better, a change being spearheaded by our private sector and selected very advanced high tech sciences public sector ! 

The CE20 Cryogenic engine which will power the third upper stage of the GSLV Mk III launch in December 2016 is going to be yet another milestone in Indian space industry. 

India as of September '16 has two power horses to ferry satellites and other payloads on our interplanetary expeditions. The much tested and reliable Polar satellite Launch Vehicle (PSLV) to ferry payloads of upto 1400 kgs to space and the operational Geosynchronous Satellite Launch Vehicle (GSLV) that can carry payloads of upto 2.5T to outer space.

In the case of GSLV, it is just a question of scaling up the payloads with more efficient and powerful cryogenic engines (under development) that can take payloads upto 10 T and more in future.
