Few important contents from the same link
Q]GSLV Mk III is equivalent to the Chinese Long March 3 and its variants. Whats the time frame for a Long March 5 equivalent(14T GTO) and what will it be called or is called?
[Ans:]No plans as of now. MkIII is more advanced than Long march 3.
Q]Are Indian spy satellites covered under the ISRO-space budget or under the Defense budget
[Ans:]No idea
Q]Does India have a Anti-Satellite capability and if its kept under wrap due to bad global PR reasons, whats the shortest span of time, India can retrofit a solution( an efficient jugaad of sorts)
[Ans:]Maybe an emergency will tell, but it can be done.
Q] How correct is the statement that the 2 Indian Space Launch vehicles can be within 6-9 months be turned into a ICBM if its required?
[Ans:]We already have good ICBMs. Why convert good old PSLV. PS: Tech is same everywhere. Go figure.
I ask as some people question the feasibility of this whereas I was also told or read even a decade back that India is not making a ICBM to avoid sanctions but it has the tech.
Again, Agni 5
Q]The Cryogenics technology took India so long to master because of the US-Soviet/Russian bilateral agreement and its implication on selling of tech to India. How is US seen in this regard since its the stumbling block for Technology transfer to India.
[Ans:]International geopolitical dynamics define such decisions.
Q]What other Advanced Technologies is still off the market for India and what portion of those concern ISRO and Indian space development.
[Ans:]After cryo, nothing very important remains. We can manage. We have got a great Semi-Cryo project going on, which would be even more awesome than cryo.
Q]What was the Indian position in the 1990's on the ISS. The US and the West intentionally kept China out citing security concerns. Why was India not involved and whats the probability India will get invoved now given that the ISS will only be up till 2020.
Sorry, I have no idea. I doubt India would join the program now.
Q]Few years back the US passed a Law which bars foreign nationals (students and Scientists from entering certain NASA enclosures) Has this(if at all) affected ISRO and the Indian Space development.
[Ans:]Nope. Even we don't allow foreigners in lots of our places
Q]ISRO mission to Venus in 2015. Whats new about it, what is going to be tested and surveyed.
[Ans:]No-one is going to Venus in 2015. Where did you hear about this?
Q]How are GAGAN and IRNSS different, this seems to be confusing me.
[Ans:]Google. Also, read other answer posted somewhere here.
Q]Why is IRNSS only limited to the Indian subcontinent Only, Why isn't it Global like the new Chinese BeiDou-2 system. Surely the sale of service like GPS does and BeiDou-2 and EU's Galileo will provide is enough incentive plus much more.
[Ans:]No, sales will not be that much. Read on the glonass conflict in usa that was in current affairs recently. For our purpose, Indian subcontinent will do.
Since its been mentioned that all ground hardware and receivers will be India made how will this be integrated into Mobile and such devices since such chips are manufactured at few places(near assembly plants).
Development is in progress.
Q] How long before we can use it in our phones?
[Ans:]It will take some time. Cannot comment on timeframe.
Q]How will the accuracy be, is using a geostationary orbit for GPS system efficient(i've read that such satellites provide limited coverage to only where the satellites are visible)
[Ans:]Accuracy will be good, comparable to other systems in use now.
Q] Lastly, all the best and keep doing your great work. Indians 200-300 years from now will thank you guys even more than you get now.
[Ans:]You are welcome. Spread the word about ISRO's activities among your friends and relatives.
