Imagine few decades from now and kids going to space museum and being shown these crappy visuals! Very inspiring in terms of achievement but not matching the same in terms of visuals spoiling the moment a bit!


Ok.... this is the Narmaal attitude... even Soviet in earlier days cared less about these visuals... but I fully appreciate the frustration around not having a proper visuals ... in consulting term .. that is like low hanging fruits... Modi and BJP should have taken care of this

Kakarat per my reading the rocket wss 41km downrange and ?? Km up when booster separated. What kind of rig did you use?
The old handheld camcorders of bulky size had maybe 1 mp camera mode but massive stabilized kinda zoom ...

Fabulous achievement.

I fully expect positive repercussions in india's economy politics defence sports trade and society.

I have previously alluded to the concept of cooperativity. This is not formally studied as applied to societies but I believe it will find application and may eventually be developed into a predicative tool.

once again Congratulations ISRO! the extensive ground testing made the first launch a confident one, the only time they seemed to worry a bit was when the CUS was started up

other than that there is software based video stabilization, one such video was posted by brar in the International Aerospace thread

Thank You, I have a few more and one i think was the moment of booster separation. Just thinking if i should post it since nothing but a ball of fire is visible

Yes, I have seen many

Kakarat, great pictures specially of the booster separation, better than DD and reminiscent of SpaceX first stage separation!! You should replace DD as official photographer/videographer for ISRO.


Actually I am a engineer and photography is my hobby, I am interested in both and I like many of us here know whats is happening and what to expect. The photo is a result of that and if the DD crew is properly managed they could do better. Now that the DD has got a new boss with a good CV lets hope for things to improve, he is also on twitter

I use a 6 years old 12MP 20X Canon Power Shot (560mm max), a DSLR is long overdue

Actually its all thanks to the cyclone end of last year that knocked down the tree north of our house which blocked the view till now, the last GSLV launch gave me an idea where to look for this time. Anyways I am planning to replant a replacement tree in the same spot once the Corporation removes the remaining tree root and until that tree grows and covers the view I will try my best to cower all the launches from SHAR

Fantastic Fantastic achievement this. In post launch credits on telecast on DD, almost all scientists said native design, materials, manufacture, execution. True Made in India. Its been a long journey from Glavkosmos, sanctions.

Recall reading interview of some French scientist years ago.. who said.. we are closely following Mk III and what it could do at Indian cost structure. Well here it is.

This might very well rank as the Top 3 Tech Achievements of Independent India.

No. I liked the elephant comparison. That sort of comparison has been done in western media for decades to tell the ordinary mango man "The rocket weighs as much as 200 cars" or "it is as long as 2 football fields". Balls to BBC I don't know why anyone would watch BBC unless he is living in Bilayat.

Our satellite launch capability is far ahead of Britain. In 1987 - living in the UK - I recall calculating that Indians GDP was 1/6th of Britain. 30 years later we are catching up with an admittedly small nation that has a 150 year lead on us in industrialization. We will soon be farting on them and all they will see is atmospheric distortion from hot fart gas from Indian musharraf

hey, I have had the elephant comparison way back in a presentation I created for school kids during Chandrayaan days. :D

Someone I know worked on the Space shute program and part of his team's job was to do image analysis of the shuttle during launch, in orbit, and during descent.
They monitored each mission round the clock and on every overpass

I don't know why our people insist on slapping on some stupid unrelated background music. Just let it be - let us hear the actual sounds of the rocket - far better background score! The amateur video posted by SSSalvi-ji captures that, it's awesome.

I liked the screaming dive in the end to shift speed from 4km/sec to 9km/sec

Been ranting ineffectually for years about a shourya based pgs weapon to smite down large ac targets deep within cheen....thats the kind of brutal dive and speed thats needed. Even the shock wave of a near miss will spray yellow matter on the fan.

All we need is a demo to change some equations.

Excellent amateur videos and photos!

I have been watching them over and over again! Of course ISRO/DD needs to ramp up their production quality 100x times. DD broadcasting/telecast is still in SLV era.

Here is my wishlist:

1. A very high speed launch and tracking video. Nowadays for $1.2 k one can have a Sony DSC-RX10M II Cyber-shot Digital Still Camera which is extremely good for the price! I am wishing that Kakkarat'ji become uber-rich and can afford the $1.2 k camera. :D

2. A really good producer., and a "muxer"., Imagine seeing the range vs. velocity chart going into PIP and the announcement that the S200 stage separated and cutaway to large view in slo-mo of the booster peeling off.

3. And no showing of people! What is point in looking at people who are thoroughly enjoying the show live and in person there! It gets depressing.

---

The S200 stage even after separation travels up and then tumbles. I have a feeling it tumbles up., follows a parabolic trajectory and hits the sea some 200 km away and then disintegrates.

If you watched DD live as I did - the resolution on the ground is itself poor. It is likely that they have sent some old cameras to ISRO while dilli and "metros" have better cameras so oil on VIP face and zits can come out well

If you see ISRO's photos and recordings they are all high resolution. They must be recording it for any potential failure analysis but they are not releasing it to the public. Typically they have high filter high speed blpast proof cameras to record the launch from various angle

Regarding Al-PeePeeCee (f)artikal on elephants, one should ask them with the units they use to show off the power of their latest (Indian owned) luxury brand. Ahem: Isn't it called "Horse Power"? There is even something called britshit horse power.

Anyway, no more pollution of this thread. Fascinating achievement, soon we will have many combinations and permutations of this product family (just like how we are doing for our missiles).

Live long and prosper, ISRO.

Absolutely. This should interest a new generation of kids of the best and brightest towards physics and aerospace engineering. GoI should hype it along with ISRO. You can't get that level of achievement if you leave India for foreign shores.

If ISRO comes with 2 more variations of LVM3, it can replace GSLV and PSLV

1. S139 * 2 + L120 + C7.5 - should get 2.5T to GTO
2. S60 * 2 + L120 + L2 - should get 1T to GTO

Since the HS is bigger in LVM3 it can handle more satellites in a single launch

Given that there is likely to be an "IT" slowdown and hopefully a push towards military make in India - Mechanical/Aeronautical/Electrical/Electronics engg should all see a boost. These are all "traditional" fields which were sidelined by "software engineer/Infotech"

It should be DRDO/HAL/Tata/Mahindra doing campus hiring and not "infosyscognizantwipro"

Shiv sir, you are forgetting L& T already a big player.

OT - for one Engineering Graduate, they hire 10 diploma guys, pay is not as attractive as IT for similar experience, onsite opportunities are zero. End of OT

Hope your wishes come true. I think Sony DSC-RX10M II is a new generation bridge type super zoom camera, I am actually looking at buying a Canon 7D DSLR and a 50-500/150-500 lens but budget has been the biggest problem

Massive achievement,totally indigenous,proves what Indian scientists can do when they're unleashed without too many fetters. This success mantra must be established in our DPSUs too,so that they can emulate what ISRO and the Strat. missile teams are achieving.

We should now make out our list of priorities.Military sats at the top. A network of mil sats for NCW,maritime sats,etc. catering to the reqs. of each service. Sat etection of any enemy missile launch fundamental in assisting our ABM systems (S-400s/whatever we develop at home too). There was some mention of a third launch pad too,but the answer was deflected as there are going to apparently be monthly launches of PSLVs as well.

PS:The launch of a 100 sats last time caught the world's attention.No longer do they scornfully report how critical items were taken to the launch pad in a bullock cart,or "why does India need rockets ,etc. when they have millions starving?" These comments are slowly disappearing. However,to sustain the momentum of all-round development in ensuring that we morph into a developed power,requires the entire Indian economy working smoothly in unison without too many hurdles.It is here where some critical industries and sectors require intelligent legislation and govt. support with less bureaucracy. We're now supposedly over 1.3B people,have overtaken China as the world's most populated nation.This will require an immense amount of infrastructure creation in terms of housing,rail.road,shipping,air,telecom,etc.,infrastructure,which have diff. contours in diff parts of the country.. Paperwork and ease of doing business ,govt. support,access to capital,in these key sectors is needed as much as in the space sector.
