249.The secret of the moon

Rockets always fascinated me right from my childhood days. Even while bursting crackers during festive seasons, my concentration would be on those fire-cracker-rockets which could propel up to around 100 feet. The topic for the day is Rockets.

The Russians and the Americans successfully tested un-manned Moon missions in the early Sixties. After almost 50 years India has done it. Yes the first Un-manned Moon mission,"Chandrayaan-1" was a success.

Chandrayaan-1 is India's first mission to moon and also the 51st satellite of the Indian Space Programme.The lifespan of this mission is two years.

What is the objective for launching Chandrayaan-1 ?

1) To design,develop and launch a spacecraft in lunar polar orbit using an Indian Launch Vehicle

2) Higher image resolution of lunar terrain along with Chemical and mineral mapping. (Hope they do not find urine samples there)

3) To enhance India's image in the Global scene by being a part of the select group which has the capability to observe planets/satellites directly.

What did Chandrayaan Carry?

1) Terrain mapper (To map the outer surface of the moon)
2) Mineral mapper ( TO map and sense for any new minerals)
3) Topography Mapper
4) Volatile object Mapper (To find if there are any volatile objects in the moon)
5) Moon Impactprobe (To find places in moon where a soft landing can be done)

Chandrayaan also carries 6 other loads from Germany, United States,Bulgaria,Sweden,Japan and UK
1) Mini-SAR from NASA (To distinguish water ice from dry lunar surface)
2)Mineralogy Mapper from NASA ( To map the geological composition of the moon)
3)Radiation monitor from Belgium ( For the study of solar particles in moon)
4)SARA from Sweden/Japan/India (Imaging of the moon's surface to measure moon's flux)
5) XRay Spetrometer from UK. ( Finding the abundance of various chemicals)
6)IR spectrimeter from Germany (To study lunar mineralogy)

The launch vehicle used for Chandrayaan-1 was none other than the tried and tested PSLV

1)The launch vehicle is 44.4 metre tall (PSLV-C11)
2) The propellant(fuel)weighs 138 tonnes (Now I realise that Rockets are indeed a big thing)
3) Moon is at a distance of 4,00,000 km from earth and Chandrayaan-1 will take 15 days to deposit all the 11 paylods in the respective orbits
4)The launch is a success but we have to wait for another 15 days to see whether all the 11 payloads have been placed in their respctive destinations.
Moon has been the only world other than Earth where human beings have set foot. No one knows whether moon has water particles or not. The moon has various other secrets too. Will Chandrayaan-1 reveal those secrets?

The man standing next to me in the picture is the brain behind this post.He is a Scientist and he heads the Liquid Propulsion plant (ISRO) of the country.I call him Papa (Daddy)



  1. u call him Papa, not Daddy. I am so proud of our Papa

  2. I luv physics dude...Ur post was like reading wikipedia...


    loved the post

    **.I call him Daddy

    u can bring fun

  3. hehehe..
    gud info and humour,both found together in ur blog :)
    nice one,yaar.

  4. Oh nice. It made for a good read! Interesting facts, did not know so much about Chandrayaan-1.

    "I call him daddy" He he....brilliant way of putting it! :)

    Thanks to your daddy for giving us so much information! Thank you! :)

  5. @akka
    check the post again.. added it..

    Fantastic post mate.. loved it.. informative and fun at the same time..

  7. @priya
    calling my dad, daddy.. was that funny? hehe.. glad to know that you love physics.. it is indeed such a cute subject... you dont have the chemical formulae that u have in chemistry and you dont have to dissect a frog too just like you do in biology.. physics is such a simple subject

  8. @archana
    good info , humor- both found in my blog? man i wanted this post to be a serious one.. did it sound like a jokers paradise? :)

  9. @tara
    he gives me lot of information.. my brain doesnt have a good storing capacity.. thats y i jotted them down in my blog..

  10. @arshat
    haha.. spoilt brat! yes.. never wanted to be a technical guy.. but our dreams are always shortlived

  11. wow!!! ur dad is a brilliant man dude...m sure his son will live upto his name :)

  12. Yes... we all love and salute ur daddy :)...

    It was nice to hear about all this... andyes I finally saw the video on youube... the cable sucks at the place i am deployed currently...

    salutes bro...

  13. nice post! informative!
    and, regards to Uncle!

  14. @ chriz
    i hate you.. i had chandrayaan as a detail answer and i just knew 4 lines on it which i made into 40 lines.. had u written this post atlease wud've assured me 10 marks!! nonsense!! if i fail its coz of u only!

  15. awwww...come on man,why not?

  17. @mayz
    are you sure? i am not sure though! hehe

  18. @the army guy
    finally you saw the code breaking act.. wow.. thats gud

  19. @josie
    he helped me to write this one.. he doesnt know that i have published it.. hehe thank you and would pass it on

  20. @anusha
    send me that answer sheet.. it would be a fun read i hope

  24. You must be proud of him!!! :) My best wishes to him!!

    And we had chandrayan for detail ans this semester!! Being a commerce student, I invented my own physics in the ans!!!

  25. hey the way u put it was funny..
    yupp true
    chemistry is wat i can't reely get thru...
    and bio ye ti's fine wth me..haven't done ny dissections may be tats

  26. @shiv
    hehe.. i am not weak in this subject.. infact i am a zero in the topic... but keeela vulundhaaalum enga meesaila mann ottaadhula.. modhala meesaiyae kidaiyaadhu
