May I ask a few simple questions:
Answer to all your 4 questions are there in my original post.
Nevertheless for your satisfaction i will answer them again.
Is this the first orbiter from planet earth?
No. But this one is unique which ill tell why in answer to another question.
If not then how is it despite many being sent this one failed and is still counted in victory dances?
Because, we sent it, simple as that. Our lengthy calculations worked. Satellites have been sent hundreds of times by many nations, and yet each successful launch is a victory as it is a complex process where thousands of variables need to be considered.
And no, the orbiter did not fail, lander failed. We can't say if rover failed, because after lander lander crashed
(presumably), rover didn't get a chance to prove its capabilities. Oribter is a success and will go on for another year.
Since it is not the only orbiter from planet earth why is it presumed that the data collected from this will benefit mankind when many others have done so previously?
All other orbiters are in an orbit around the equator of moon i.e. East-West on an axis which has been studied for a long time and we know about it as much as we know about our own planet Earth. What we haven't studied so far are the poles among which south pole is fo greater significance as it doesn't get much sunlight and thus possibly contains higher concentration of water in form of ice and maybe even single celled or primitive life signs since there is more water there.
ISRO's orbiter, which is working perfectly as it was intended to do, is in a polar orbit i.e North-South instead of East-West, thus it will be able to study poles of moon and gather new data of any past life that if it ever existed there and composition of polar surface and ice formation.
I am not into space science hence these are genuine questions as to what is so special about this one?
Answered what is special about this rover above.
Cheers.
