- NISAR Mission 2020: to measure land surface
- GSAT-16: Communication satellite
- GSLV-Mark 3 for “FAT” satellites in future
- Liquid Apogee Motor (LAM) to drive vehicle carefully
Combining space-tech related topics from September W1 to October W3, in three part series
- IRNSS: the desi GPS
- Stuff send to space: NISAR-mission, GSLV-6, GSAT MK-3
- Stuff build on land: TMT, INO, TOPS
Apart from this lot of ball by ball commentary happened- Comet Siding spring, ESA’s Rosetta Mission, NASA’s Orion mission, Lunar Eclipse, Blood moon. But I don’t consider them much important for Mains-2014. Although I’ve noted them down, will release them later under prelim space-tech series 2015.
NISAR Mission 2020: to measure land surface
Topic in News: October W1, 2014
|Full name||NASA-ISRO Synthetic Aperture Radar (NISAR) mission|
What’s the purpose of this mission?
- Measure the changes on earth’s land surface, ice surface, glaciers, earthquakes and volcanoes.
- Find causes and consequences of such changes.
- NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band). Hence It can capture resolution even less than a centimeter of earth’s surface.
What’s the utility of such data?
- Understanding climate change
- Predicting natural disasters in advance.
Mock Question (GS3) Write a short note on NISAR MISSION 100 words.
GSAT-16: Communication satellite
Topic in News: SepW2, 2014
- Existing system: INSAT-3E at 55 Degree East Longitude.
- INSAT-3E is a communication satellite that powers DD and private TV channels, internet and radio signals.
- But INSAT-3E is getting old and outdated. Stopped working in March 2014, after serving for almost a decade.
- Solution? = replace it with GSAT-16
|Launch Vehicle||European Ariane-5 launcher|
Mock Question (GS3): Discuss the features and utility of GSAT-16 (100 words.)
GSLV-Mark 3 for “FAT” satellites in future
Topic in news: Oct W3, 2014 (Because ISRO planning launch in next 45 days)
|Polar satellite launch vehicle||Geosynchronous satellite launch vehicle|
|First launch 1993||2001.|
|Can carry upto 1600 kg satellite||2500kg|
|Used for launching Indian remote sensing satellites (IRS) such as CARTOSAT, RISAT, OCEANSAT, RESOURCESAT||For launching Indian National satellites (INSAT) such as INSAT 2E, 3A…., GSAT-2,8,12.|
|Latest version is PSLV-XL. Can carry upto 1750 kg. It was used to launch Chandrayaan, RISAT. And in future, it’ll be used for Mars mission as well.||
What is GSLV Mk-3?
Latest version of GSLV -Geosynchronous satellite launch vehicle.
|(ordinary) GSLV||GSLV Mk-3|
|Carry upto 2500 kg||
|49 meters tall||
|414 tonnes||629 tonnes.|
- Nov-Dec 2014: ISRO planning a test-launch it, using a dummy crew module.
|1st stage||Solid propellant|
|2nd stage||Liquid Propellant|
|3rd stage||Cryogenic Engine. (although during test-launch, ISRO won’t use this)|
GSLV MK-3 has multi-mission launch capabilities:
- GTO (geo transfer orbit)
- LEO (low earth orbit), Polar
- Intermediate circular orbits.
- Therefore it can be used for launching satellites into different orbits, according to Mission requirement.
- Thus, GSLV MK-3 will make ISRO a competitive player in commercial launches of foreign satellites (and earn million$$).
Mock Question (GS3): GSLV MK-3 will augment the both communication and commercial operations ISRO. Elaborate (100 words.)
Liquid Apogee Motor (LAM) to drive vehicle carefully
Topic in News: Sep W2, 2014
- LAM- Liquid Apogee Motor: is a special device on such liquid-fuel powered engines.
- LAM Helps moving the satellite to the precise orbit.
- LAM uses following chemicals: Helium gas, Nitrogen Tetroxide, Monomethyle Hydrazine
- ISRO originally designed this instrument for INSAT-2 and other communication satellite.
- Recently, ISRO used LAM on its Mars orbiter and on IRNSS satellites.
Mock Question (GS3): What is the utility of Liquid Apogee Motor (LAM) module developed by ISRO? (100 words.)
solid article sir…..really u made this INSAT GSAT satellites understood in lucid way. great mrunal and shivaram sir. sir hard copy of ur all article can be obtained??? please sir if posssible then help sir,,,,it will help in revising at the last moment
You can print them out mate. Use chrome and click on print/PDF option.
Print lelo bhai, kyun kaam badha rhe ho Sir ka
Take print out… i do the same
Thank you so much for the article sir.
thank you very much sir. its very use full to us
v nice sir….thank u very much…ur blog is of amazing help to us sir
thank you very much SIR
thanks for Giving focus on ISRO future plan and launching vehicles…
very very useful informations
Sir thnks a ton.U are really striving hard to making the aspirations of unknown friends true.I don’t know why we are searching examples of ethics , morality , humanity and Co brotherhood for paper 4; you are a solid example for that.selfless devotion, perfection and so many other qualities you are bearing .We are alwys keen to see your latest posts..I don’t know what are your motives behind such a nobel effort , but I must say u just deserve applause and acts to be annulled by each one..Thanks once again.keep it up buddy.
Sir ji, GSAT 16 launch date has been preponed to December 2014.
Thank you very much sir
The third bullet in the first point of GSLV Mk 3 in the differences between GSLV and GSLV Mk 3 table is incomplete. Kindly look into it

I want to take loan for IAS coaching so any one know is there any scheme for tht means provide at less interest rate or any other? If have any idea then pls suggest me.
thank you sir, for such a nice article…
Take print out … i do the sama
What is your Message? Search before asking questions & confine discussions to exams related matter only. i missed my hall ticket of upsc civil services so, i would not check my result. please suggest me.
“NISAR will be the first satellite system to use dual frequencies. (S band and L band)”
“IRNSS -1 C satellite uses two different frequencies of microwaves: L5 and S bands”
Aren’t the two statements contradictory?
We already launched IRNSS-1 c this month!
Please somone explain it.
same doubt .. INRSS has been already launched with dual frequency … someone explain
Incase of INRSS , microwave frequency was used with L5 and S band, while NiSAR uses two Radar frequency which is the first one to be used.
NISAR will be the first ‘Radar’ imaging satellite to use dual frequency
You are the Great Great person sir..
Most of the competitive exam websites are money minded…
You are giving worth articles for all competitive exams for free…
You are an Inspiration for all dedicated competitor!!!!!!!!!!!!!!!!
thanks for another masterpiece
thank you sir
Excellent article sir. I wish to make two additions:
1) GSAT 16 to be launched in December 2014 and not June 2015
2) GSLV Mk III also provides us with an opportunity to realize our dream to launch human crew to space.
