Today, GSLV To Carry A Satellite And India's Hopes For Moon Mission

Best wishes to ISRO!

All the best to ISRO....

1. What makes the INSAT 3DR special is its imaging capabilities for night-time pictures. It also carries on board a special search and rescue transponder, which will help in satellite-aided rescue operations.

@Abingdonboy @PARIKRAMA i wonder what else this satellite can be used in....hmmmmmmm

I wish you well on this (as this is a peacefull endeavor)

Nice to have someone with different flags actually wishing us well

NEW DELHI: Countdown for the Indian Space Research Organisation's big launch has started at Sriharikota. An indigenous weather satellite - the INSAT 3DR -- is set to begin its journey tomorrow afternoon, piggybacking on the GSLV. But more than the satellite, it is the flight of GSLV that will be crucial for India.

Here are the Top 10 points to this big science story

1. The lift-off will take place at 4.10 pm from the launch pad at Sriharikota, Andhra Pradesh.
2. The success of GSLV (Geo-synchronous Satellite Launch Vehicle) is crucial for India since it will be the vehicle to launch the second mission to the moon -- Chandrayaan-2 -- next year.
3. A successful launch will also boost India's efforts to make a dent in the multi-billion dollar commercial space launcher market.
4. The 415-tonne GSLV rocket, with its indigenous cryogenic engine, is being tested for the tenth time. This is its first operational launch.
5. Dubbed the "naughty boy," this rocket has had a patchy record, with five of its nine flights resulting in failure.
6. The rocket is almost 49 meters high -- as much as a 17-floor building. It weighs 415 tons -- as much as the combined weight of 80 full grown elephants.
7. Rocket launches are still a very risky business, which became evident when the Falcon- 9 rocket by Space-X exploded on a launch pad in USA on September 1. Space-X a private company is owned by billionaire Ellon Musk, which is now experimenting with cheaper space launches.
8. The GSLV will be carrying the 2211-kg INSAT 3DR, which will eventually be placed in a geo-synchronous orbit 36,000 km above Earth.
9. What makes the INSAT 3DR special is its imaging capabilities for night-time pictures. It also carries on board a special search and rescue transponder, which will help in satellite-aided rescue operations.
10. Together, they represent an expenditure of Rs. 300 crore.

Wish the best!! Is it MK3?

That means the enemy can't take the cover of darkness anymore. In other words there will be no place to run, no place to hide!!

INSAT-3DR: This is a follow-on mission to INSAT-3D to ensure data continuity for meteorological observations, and
monitoring of land and ocean surfaces using Imagers and Sounders for weather forecasting and disaster warning.

This should aid our HADR ops by combination of developing met events and forecasting the triggers..

Don ask me about monitoring land and ocean surfaces day and night thing ..

No Its not mk3. That will be launched in December.

Thanks. it was stated in the OP that " indigenous cryogenic engine" would be used. India has different indigenous cryogenic engine other than CE20?

Thanks. it was stated in the OP that " indigenous cryogenic engine" would be used. India has different indigenous cryogenic engine other than CE20?

Yes. Initially CE 7.5 was developed. Now we have developed CE 200 , but GSLV MK 2 will use CE 7.5 .

 

[Dungeness]

Yes. Initially CE 7.5 was developed. Now we have developed CE 200 , but GSLV MK 2 will use CE 7.5 .

Thanks for the info. Which one will be used on this launch? CE 7.5? I couldn't find any info about CE 200, any spec?

 

[kaykay]

Thanks. it was stated in the OP that " indigenous cryogenic engine" would be used. India has different indigenous cryogenic engine other than CE20?

India has so far developed 2 cryogenic engines. CE 7.5 and CE20. CE 7.5 is meant for Gslv mk2( in this launch) while CE20 will be used in gslv mk3.

All the Best ISRO

May be he meant SCE-200 which is under development and will be ready for testing by next year. It will have a thrust of 2000 kn.

For long we have been beyond the point where a successful PSLV launch was a thing for the whole nation to cheer for - it has become a routine affair. However, the GSLV has given us trouble for a long time. Firstly because of certain incompatibility issues with the Russian cryos we bought, and then we had trouble making our own engine in the face of international isolation in this matter. We did not even receive ToT for the Russian engines to help us with our efforts.

We had to carry out an R&D cycle to reinvent the wheel, duplicate the efforts & the results. It was a tiring job, but we did it.

I still remember ISRO officials speaking on the TV during the event of GSLV launch on the last of the small bunch of Russian cryos we had...something like "This is our last Russian cryogenic engine, we can't launch our rockets on procured engines any more after this. Because after this, we will make our own."

If this launch goes as planned, it will be the 3rd successful launch of GSLV Mk-2 in a row. Will be a big boost toward making this a reliable launch vehicle. It has to be a a reliable vehicle if it's going to uphold the legacy of the PSLV's terrific 95%+ success rate.

Oh, and a GSLV Mk-3 launch with a cryo engine is scheduled for later this year - it will be carrying GSAT-19E which has electric/ion thruster propulsion for orbital maneuvers.

So, best of luck to ISRO for all it's ongoing & planned endeavors!
