Tentative launch window is between July 25th - August 10th. RLV-TD will fly from FLP in september. (http://www.defence.pk/forums/indian-defence/241849-rlv-airframe-under-construction.html (http://www.defence.pk/forums/indian-defence/241849-rlv-airframe-under-construction.html))
Is this protrusion odd in GSLV-D3?It looks like that it has a temporary protective cover. It also appears to be on the rockets umbilical side. So it is possibly an umbilical interface that has been covered.

Countdown even before vehicle rollolut from VAB to launch pad !! ? This is unlikely as the launch is still a week away.
Are they gonna use Acoustic suppression system in this launch??
What is the mass of GSAT-14, some sites are saying it is 1980 kg while ISRO is saying it is 2050kg which is it?
Video Imaging system is installed on the the vehicle. Hope they telecast the video and not just use it internally.
A very serious security breach has happened. Without the knowledge of ISRO officials some one has secretly intruded into the ISRO premises and shot the videos using spy cams. What is the ISRO security department doing ? Who is responsible for these serious security breach? Also how come the composition and working of Cryogenic has been made public?

Gee, so hopefully this time we'll get to see some onboard footage from the rocket's perspective, as it takes off from the ground and ascends to orbit?
That's certainly one thing I've been missing while watching ISRO launches, in comparison to NASA and SpaceX launches. Seeing onboard video showing the progress of the flight is a lot better than watching ISRO's typical boring plotgraphs. This is long overdue.
S-band telemetry and C-band transponders enable GSLV-D5 performance monitoring, tracking, range safety / flight safety and Preliminary Orbit Determination (POD).

I don't think the launch time has moved - in fact the ISRO main page (http://www.isro.org) is now showing that the 29 hour countdown has commenced at 06:20 UTC.
^11:00 UTC should translate to 4:30 PM. IST not 4:50 PM. IST ??4:30pm (IST) /11:00UTC launch time was apparently a misunderstanding from the press (PTI) and has now been reverted to the original 4:50pm (IST)/11:20UTC
status update ( http://isro.org/ ) : propellant loading of 2nd stage in progress.
Regarding the assembly of the launch vehicle in the Vehicle Assembly Building and its subsequent transport to the launchpad on that slow crawler -- is this all necessary?
Why not just mount the building and launchpad on rail tracks to shift them in or out of the way, while leaving the launch vehicle stationary? Seems to me that these large structures are less critical than the launch vehicle itself, and so they could be shifted more rapidly and less gingerly without having to use a slow crawler type of pedestal

They do that for the PSLV don't they? I don't think the pad-roll out is on the critical path. As in shaving time off there probably wouldn't enable faster launch processing. Moreover, I don't think it's less critical than the LV. If you break the VAB while moving it, that's going to cause delays and disrupt the next launch. And possibly even scrub the existing launch, since they don't want to risk further damage.
But so that sort of makes it sound like the crawler thing is an evolutionary improvement over the pad assembly. Why is doing it the crawler way better than the old way?

I believe you are seeing water sprayed onto the pad from the tower, possibly for acoustic, fire or thermal control to minimise damage.
Modified design of the Fuel Booster Turbo Pump (FBTP), taking care of the expansion and contraction of the bearings and casing at cryogenic temperatures- I was tempted to blame similar 'unexpected' contraction for the 2nd stage counterparts, for the leak, but the cold stuff is whole stage apart. So, I'm leaning toward some contamination/corrosion/manufacturing defect as a cause.
Wow, months.
But as with all rockets, that's good news when they find the issue on the ground and not half way uphill!
"Next flight in December for which first and third stages are preserved. Second stage is being prepared"
"ISRO used an old tank delivered 4 years ago in the second stage which might be prone to cracks"

ISRO to assemble new stage for GSLV flight:

Preparations in full swing for December 15 GSLV mission (http://www.deccanchronicle.com/131105/news-current-affairs/article/preparations-full-swing-december-15-gslv-mission)
Thanks for that article. It mentions its performance to a variety of orbits, is it known what it can launch to the Moon or Mars as I know it will also be fulfilling India's further ambitions in interplanetary missions?
PSLV is a four stages rocket. GSLV is a three stage with an H2 third but a very inefficient first (the boosters actually carry the empty weight of the first stage for almost a minute!).
Wow, months.My initial reaction was: oh no! how much money will be lost (high taxpayers, ISRO & to Govt/businesses who can't lease/buy) because of this leak disaster and the impending delay :-X
But as with all rockets, that's good news when they find the issue on the ground and not half way uphill!
Speaking to reporters at the city airport, Dr K. Radhakrishnan, chairman of the Indian Space Research Organisation (ISRO) said that scientists identified problem in the cryogenic stage of the GSLV and had rectified the issue. “The launch vehicle is ready for launch and we plan to launch it in December,” he said.
The indigenous cryogenic third stage engine is ready. The mission readiness meet will be held on December 3 and the GSLV-D5 will be launched by December third week from Sriharikota
This article places the launch in third week of December:
http://bit.ly/18nN6DD (http://bit.ly/18nN6DD)
" ... The GSLV Mark III variant, initial launch planned by April next year is a sub-orbital flight test having the first and second stage active solid and liquid propellants, its cryogenic stage will be passive," said Vikram Sarabhai Space Centre (VSSC) director S Ramakrishnan.
"An advanced heavy cryogenic engine C-25 is being designed with 25 ton propellant loading with 20 tonnes of engine thrust for the GSLV Mk-3 D-1 mission in early 2017," he said. "The huge cryogenic engine is slated for completion and testing by 2015."(Emphasis mine)
Oxygen remains a liquid only at temperatures below minus 1830 Celsius and Hydrogen at minus 2530 Celsius, developing a cryogenic engine from such propellants is a crucial test.
Thailand has been warned of potential debris falling close to its territory from GSLV D5 launch "between December 15 to January 14"
(source (http://www.nationmultimedia.com/national/Falling-satellite-carrier-expected-to-land-in-sea--30222068.html))
Thailand has been warned!!!! Does this mean that our scientists are not confident of successful launch :( ?
In other words, why aren't we considering the very tip of India, or a straight south (or even North) trajectory for the PSLV etc.? We can just warn Sri Lanka (or parts of India) like we've warned Thailand prior to a launch.

It is possible that this could have something to do with reliability - or in the GSLV's case, lack thereof. To date, more GSLVs have ended up in the Indian Ocean than the correct orbit, its success rate is less than 30%, and it hasn't had a successful launch in the last four attempts. The PSLV by contrast has had 21 consecutive successful launches with around a 90% success rate overall. So maybe they just realise this one is more likely to fail.
Now it's a question of numbers. How much does the launch angle and the subsequent yaw manoeuvre cost us in terms of mass penalty? Would it open up a new market segment?
Seems like this might be one of the more dramatic examples of course shaping among world-wide launch sites? I suppose that imposes some performance penalty, as would trying to shoot for the poles from anywhere this close to the equator?
Performance penalty is close to 500 Kgs of payload loss. ISRO is considering second spaceport that will not require such course shaping.
ISRO is working on third launch pad in SHAR and considering a new launch site that will improve the payload capacity of current launch vehicles by 500 kgs. Currently, a launch blocks the launch pad for 60 days. With the third launch pad, ISRO is hoping to reduce the gap to 30 days. We need more frequent PSLV launches that will boost commercial activities.
"The GSLV launch will be in January. The exact date will be decided Dec 27 at a meeting," M.Y.S.Prasad, director, Satish Dhawan Space Centre (SDSC), told IANS over phone from Sriharikota in Andhra Pradesh.
ISRO officials told IANS that the rocket would be moved to the launch pad Dec 28 or 29 and after that around 10 days would be needed to ready the rocket for its flight.So launch not earlier than January 7

The leak was blamed on the fuel tank made of aluminium alloy called Afnor 7020 which tended to develop cracks over a period of time. The GSLV-D5 was dismantled and the “restoration process” done under the guidance of K. Narayana, former Director, Satish Dhawan Space Centre, Sriharikota. The GSAT-14 communication satellite, which was encapsulated in the heat shield, was preserved and tested periodically.
Since the liquid fuel leaked from the second stage tank made of aluminium alloy Afnor 7020, the Liquid Propulsion Systems Centre (LPSC), ISRO, Mahendragiri, Tamil Nadu, came up with a new second stage with its propellant tank made of aluminium alloy 2219. The four strap-on booster motors were refurbished. The rocket’s first stage, which uses solid propellants, has been replaced with a new one. The restored vehicle has new electronic components because the components in the four strap-on motors in the earlier vehicle had become wet from the fuel leak.
....
The GSLV-D5’s cryogenic stage had been stored for the past three months-and-a-half. Mr. Dathan added: “The cryogenic stage’s critical components and valves have been tested, and found in good condition. There are three levels of checks on the vehicle. Phase III, level I checks have been done. This means all the fluid lines and electrical circuits have been checked. Everything is giving results as expected. We are ready to go ahead with the launch.”
Dr. Radhakrishnan said: “We got a new S139 solid first stage. Its four liquid strap-on stages have a lot of avionics, so we refurbished them at Mahendragiri and Hindustan Aeronautics Ltd. We also made a new second stage. When the launch was called off in August, the liquid stage had to be drained of fuel and washed with much water. This might have affected the electronics systems, so we replaced them, too.”
More importantly, the fuel tank material has been changed, fully phasing out the traditional but corrosion-prone aluminium-zinc combine, called AFNOR 7020. The new alternative, aluminium-copper alloy called AA2219, is now the material for all PSLV and GSLV tanks.
Mission Status: GSLV-D5/GSAT-14
We are all set for the launch, the launch rehearsal has been successfully completed a few hours back, all results are apparently normal.

I presume the 4 L40 stages remain attached to the core solid booster for pitch and yaw control (using gimbal controls on L40).
I presume the 4 L40 stages remain attached to the core solid booster for pitch and yaw control (using gimbal controls on L40).
The 4 L40 boosters remain attached to the core to provide thrust for the entire stack after the core burns out. For some reason, ISRO decided on a system where the core burns out 40 seconds before the strap-on boosters.
I understand that the reason is to reuse the PSLV first stage. The GSLV MkI/II was a short term solution for GTO until the MkIII was ready. Thus, they based it off the PSLV, and tried to do the minimum additions to get the desired performance. Thus, the rocket is not exactly very efficient, but it was done that way due to budget and schedule restrictions. Now, given all the failures, were attributed to the new elements, it was not a bad idea to use already developed parts with minimum mods.

Can anyone here confirms that all the photos and videos currently on the ISRO website are from the second launch attempt and not from the one last August? Thanks!
Sure, it may not be paint, and it may just be the colour of the insulation material, but what good insulators are coloured black?It is not a black paint but I guess its a "Multilayer Insulation blanket" wrapped manually. It came in all colors.
Did they replace the booster or just repair it?The stage that leaked was replaced with a new one made from an alloy less susceptible to cracking; the first stage is also new, and the boosters were refurbished.

I think you can assume they are rather pleased about the mission ;)
congratulations...What were the final parameters ?
congratulations...What were the final parameters ?
It was almost a textbook launch. The targeted apogee was 36000 km, the actual apogee is just 50km within this value. Even the achieved perigee is within 0.5% of the desired distance.
USSTRATCOM has catalogued a first object (presumably the 3rd stage)
2014-001A/39498 in 160 x 35710 km x 19.41°
(The target injection orbit for GSAT-14 was:
perigee 180+/- 5 km
apogee 35975 +/- 675 km
inclination 19.3 +/- 0.1°)
The GSLV-D5 placed the GSAT-14 communication satellite in an orbit with an apogee (nearest distance to earth) of 179 km, against a targeted 180 km with a plus or minus 5 km margin for error, and a perigee (furthest distance from earth) of 36,025 km against a target of 35,975 km with a 675 km margin of error.http://www.indianexpress.com/news/isros-mission-successful-gslv-d5-completes-flight-gsat14-satellite-separates/1215701/

Amazing! Congrats to ISRO. I was at Sriharikota today to witness the historic launch. Electrifying excitement all over :) Looking forward to more successful GSLV launches.
Superb launch :) Very enthusiastic celebrations in the control room for this one too :D
Were you in SHAR? Is there an ISRO designated viewing area for the public - either inside or outside? Or is everyone scampering to get to the terrace of the tallest building nearest to the complex? Did you make it a point to tell them to start selling tickets for tours - for the revenue generation (small though it may be) and outreach? :D

ISRO does have a theater/hall to display the launch. The launch is projected onto a screen live from the MCC. This has been for years. The tickets (known as entry pass) are not sold and rather given on a first come first serve basis to employees and their families/relatives..etc
There is also a walky-talky system which announces critical launch event from the MCC. This system is setup in many public areas especially in residential colonies(I am not sure of how many of these are setup)
Apart from these, people generally crowd places like water tanks, tall buildings etc in SHAR and also in the nearby town Sullurpeta
The CE-7.5 indigenous cryogenic upper stage engine has a claimed 454 second specific impulse, better than the Ariane 5 ESC-A stage HM7B engine, better than the Atlas 5 Centaur RL10A-4-1 engine, better than the Long March YF75 engine, better than Japan's LE-5B-2 engine, and so on.

Nominally the target orbit was "super-synchronous" with apogee higher than GEO; the achieved orbit was just slightly lower than GEO.The target orbit was not super synchronous.
They keep referring to the cryogenic stage... I assume this is a HydroLox stage?
The first orbit raising operation of GSAT-14 is planned at 0758 hrs IST on January 6, 2014. The remaining two orbit raising operations are planned on January 7 and 9, 2014 to place the satellite in geostationary orbit.http://isro.gov.in/pressrelease/scripts/pressreleasein.aspx?Jan06_2014
GSAT-14 first orbit raising operation successfully completed.
may be because CE7.5 is staged combustion and others are either gas generator or expander cyclesAsking again: would you provide your source? (http://forum.nasaspaceflight.com/index.php?topic=15187.msg1143127#msg1143127)
ISRO does have a theater/hall to display the launch. The launch is projected onto a screen live from the MCC. This has been for years. The tickets (known as entry pass) are not sold and rather given on a first come first serve basis to employees and their families/relatives..etc
There is also a walky-talky system which announces critical launch event from the MCC. This system is setup in many public areas especially in residential colonies(I am not sure of how many of these are setup)
Apart from these, people generally crowd places like water tanks, tall buildings etc in SHAR and also in the nearby town Sullurpeta

The Third Orbit Raising Maneuver of GSAT-14,successfully completed. Initial data:35,462 km Perigee/35, 741 km Apogee/0.25 degree inclination
ISRO Confirming this, USSTRATCOM has tracked the satellite, after the second orbit raising maneuver, in the following orbit:@ISROOFFICIAL 7 Jan The MEASURED orbital parameters after the second Orbit raising maneuver is 32,544 km (Perigee) by 35,742 km (Apogee); 0.6 degree inclination
Mission Status: GSLV-D5/GSAT-14 mission:
All orbit raising maneuvers for GSAT-14 satellite have been successfully completed. Both the reflectors of the satellite have been deployed. Satellite has been put under the three axes stabilized mode. The satellite is slowly being drifted to its designated orbital slot of 74 deg E. It will reach there on January 18, 2014 ...
ISRO chief reflects on the success of GSLV, says that the payload injection was so precise that satellite could save some fuel for orbit correction, thereby gaining extra 1.5 yr life.

The politician says something about Kulasekarapattinam at the end. I've heard ISRO is considering this location seriously for the 2nd spaceport.
Meanwhile, minister of state in Prime Minister's Office V Narayanasamy said on Friday that the third rocket launching pad is being considered in Kulasekaranpattinam of Tuticorin district by the central government. Talking to reporters at Mahendragiri, the minister said that there has been a demand for setting up the launching pad in Kulasekaranpattinam, as it is found to be a vantage point.http://articles.timesofindia.indiatimes.com/2014-02-01/science/46897203_1_mahendragiri-vikram-sarabhai-space-centre-gslv
The Cryogenic Engine develops a nominal thrust of 73.6 kN (vacuum) with a specific impulse of 452 seconds. The engine works on Stage Combustion Cycle in the pump-fed mode with an integrated turbopump running at around 40,000 rpm. The steering engine with the thrust of 2.2 kN provides three-axis control of the vehicle during thrusting phase. During coast phase, the OSS provides the required control to the vehicle. The unique feature of this engine is the closed loop control of both thrust and mixture rati os, which ensures optimum propellant management during the mission. The overall stage length is 8469 mm and the stage dry mass is 2548 kg.
