Lots of interesting stuff...Will try to provide an overview of the most significant updates later.

Annual Report for 2015-16

Just for the record...

This is how the RLV TSTO is supposed to be.

There was one news article in ToI that talked about SpaceX beating ISRO in terms of cost advantage once their reusable rockets mature. They havent refurbished and launched any of the 3 returned boosters yet, so we don't really know cost-wise yet. If it does turn out that way, I wonder how long it w...

I couldn't find any concrete answers through Google chacha. However it looks like ISRO is doubling down on reusable shuttle option and not reusable rockets like Space X. Is there a plan in the medium future to develop reusable rockets? It looks to me that a mature space program would need both. Can...

Good to see you back Rohit_K, been a while. Bangalore <none> BMRCL has not yet invited CMS for conducting a safety audit of Purple line's underground corridor. This part speaks volumes when read along with the other updates. Namma metro seems to be in a mess, perhaps due to the underground issues v...

Although not quite related to AMCA, Japan unveiled a downscaled prototype of its 5th gen aircraft.

I believe the RLV HEX will be launched FLP.

PSLV can't support all these ambitious missions. Worry about getting the GSLV Mk.2/3 certified first by launching satellites. Only then, will it be feasible to start doing these missions. Venus hot-air balloon mission has never been done and talked about before by ISRO, it would be a really amazing...

Its a tremendous achievement and I would like to congratulate the whole team on getting bird till here. Sir, if I might ask, what mach numbers have been achieved by LCA at sea level and overall? Also, the GE414 for Mk2 were scheduled to start arriving by december 2015. Since Mk1A is the priority, w...

what are the military applications of IRNSS satellits? Guidance!! For missiles, aircraft and what not. ISRO was working with some application developers in Bangalore o bring this to the civilian area. The devices(mobiles etc) will need a some small piece of new hardware to start making use of the I...

Grand mufti bans chess in Saudi Arabia Remarkably, chess is actually an Arab invention which was exported by Muslims from Persia to Europe during the Islamic Golden Age from the 7th century onwards. :lol: :lol: The Gulf region is no stranger to seemingly weird fatwas.

^^ Condensation usually depends on the Gs being pulled by the aircraft and also the altitude because closer to sea level and the coast the air would be more moist right?

So, I guess it is a combination of the higher Gs and the lower altitude at Bahrain.

^^ Interesting that the TSP consulate was targeted! :twisted: Hmm..why would ISIS target the Pakistani consulate? The Indian and Iranian consulates would have been better targets considering they were close by and would have resulted in much wider propaganda value for ISIS. Considering that ISIS ar...

I read somewhere that there are no Indian records of Alexander's invasion at all. It must have been something really minor. There is text describing the events around the fall of Nandas and rise of Chandragupta Maurya. It's the Mudrarakshasa. It was actually composed a long time after the events (I...

Some new info on Chandrayaan-2 and future Chandrayaans.

1. PSLV /GSLV core stage is a 4800 KN thrust solid (and hence a low isp). Replacing that core stage with a 4000 KN (ie 4MN) thrust high isp liquid will result in a far more efficient vehicle, and you can get rid of a lot of boosters and maybe even the 2nd stage 2. A PLSV --> with the 4MN liquid cor...

member_29267

Sorry. Meant Atlas V and not Saturn V. The Atlas V (one of the most efficient launch vehicles), is basically a 4MN thrust RD-180 topped by a 100 KN cryogenic stage. A GSLV with a 4MN thrust LOX/Hydrocarbon core topped with the 200 KN CE 20 will be pretty competitive. Let us first see what ISRO want...

The 8 F414s ordered by ADA for Mk2 PVs were supposed to arrive by end of 2015 right? Do we have any further cues on that?

member_29267

I already mentioned the long delays in the RLV TD program. But, given the current status and the issue at hand it would be good to say that we shouldn't be expecting years worth of delays anymore. ISRO might have a history of not keeping schedules and very long delays, but I do see them working on t...

Rest assured theere will be no RLV flight in 2016. Sorry? The HEX is scheduled for February or April as per ISRO . Sure things might delayed but the timeline waswhat ISRO gave. Yes it has seen a lot of delays but I am expecting to see it happen in the next year and then we would see ISRO start focu...

member_29267

Well, ISRO mostly prefers names based on the functional aspects (GSLV, PSLV, RISAT, INSAT, IRNSS) or even after personalities (Aryabhatta, Bhaskara, Kalpana). There have been instances where ISRO did give the spacecraft like Chandrayaan, Aditya (mind you the official name of Mangalyaan is Mars Orbit...

PAM-G is different from PSLV 4th stage. PAM-G has more fuel. The first use will be Chandrayaan-2. Hopefully it will replace PSLV 4th stage later. It can be incorporated to GSLVMk3 replacing C-25 so that a uniform core can be used for different payload reqs But, PAM/G was developed based on the PSLV...

member_29267

Latest info about 2nd burn: A unique feature of this flight is that 46 minutes after all the satellites are launched the 4th stage will Re-start and will remain ignited for 4 seconds. This may appear to be an insignificant thing but there are technological achievements for ISRO if this happens. Thi...

All of the Jaguars should be upgraded. At least the quote asked from Honeywell was for 270 engines. We don't need to subvert this order for the HTFE-2500. Even if we get all the trainers, that will be close to 1000 engines over the lifetime. If the core is to be used for turboshafts, the order will...

One of the little known facts about Bengaluru is that we had (still have) a couple of rivers (or rivulets) flowing through the proper city. Sadly, these have been turned into drains during the past 30-40 years. These rivers are the tributaries of the Arkavathy river which in turn joins the Kaveri. 1...

I do not understand why the forest officials in Gujrat are doing this. The lions have to have the at most importance. If it makes sense to move them Kuno Barda then do it. Stop giving stupid reasons. I hope the supreme court forces them to comply with the reintroduction project at Kuno Barda.
