0915 GMT (4:15 a.m. EST)
Today's mission marks the eighth launch of a Geosynchronous Satellite Launch Vehicle since 2001, and the third flight of the upgraded GSLV Mk.2 version with an Indian cryogenic third stage.

Six of the GSLV's seven missions to date have flown with Russian-built hydrogen-fueled third stage engines, but India attempting to demonstrate its own cryogenic third stage to give the nation a launcher with all-Indian components.

The first GSLV launch occurred on April 20, 2001, with the GSAT 1 satellite. The mission was a partial success, delivering its payload to a slightly lower-than-planned orbit due to the premature shutdown of the rocket's Russian third stage.

Two subsequent launches of the GSLV in May 2003 and September 2004 proved successful before the GSLV was hamstrung by a series of mishaps.

A launch in July 2006 ended when the GSLV veered out of control and disintegrated about 55 seconds after liftoff due to a malfunctioning propellant regulator inside one of four liquid-fueled strap-on boosters, which allowed excess propellant to flow into the Vikas engine, driving up temperatures and pressures inside the engine.

The next GSLV mission in September 2007 placed the INSAT 4CR communications satellite in orbit, but the rocket's third stage again underperformed, deploying the spacecraft in the wrong orbit.

India followed with another GSLV launch in April 2010, the first time the launcher had ever used an Indian-built third stage. The rocket fell short of orbit due to a fuel pump anomaly on the indigenous cryogenic upper stage.

Another GSLV launch in December 2010, which reverted back to using the Russian third stage, disintegrated in a fireball less than a minute after liftoff, when cables between the launcher's computer and strap-on boosters inadvertently disconnected in flight, causing the GSLV to lose control.

ISRO considers four of the seven GSLV missions to date to be failures.

0735 GMT (3:35 a.m. EST)
The GSLV's third stage is now being filled with liquid hydrogen fuel, according to ISRO.

0620 GMT (1:20 a.m. EST)
Super-cold liquid oxygen is now being pumped inside the Geosynchronous Satellite Launch Vehicle's cryogenic third stage, a key part of today's test launch from the Satish Dhawan Space Center.

The third stage is the only part of the GSLV not already loaded with propellant. Its liquid hydrogen tank will be filled next. The third stage tanks will contain more than 28,000 pounds of propellant at the time of launch.

After the 161-foot-tall rocket rolled to the launch pad Dec. 28, engineers completed final preparations on the launch vehicle and commenced the 29-hour countdown at 0548 GMT (12:48 a.m. EST) Saturday.

Later Saturday, the GSLV's second stage and four L40H strap-on boosters were loaded with hydrazine and nitrogen tetroxide propellants.

The second stage and four strap-on boosters are powered by hydrazine-fueled Vikas engines, each producing about 150,000 pounds of thrust.

The GSLV's first stage is powered by a solid-fueled motor generating more than a million pounds of thrust. Its propellant was packed inside the motor casing before the rocket was assembled.

Fueling of the third stage comes last in the sequence because its cryogenic propellant is stored at frigid temperatures, and the liquid oxygen and liquid hydrogen boils off when exposed to ambient temperatures.

Интересно, каким образом Стефену Кларку удалось насчитать третий пуск с индийским водородником?

0948 GMT (4:48 a.m. EST)
 T-minus 60 minutes. No problems have been reported so far in the countdown. Here are some statistics on today's flight:

[/li]
• 8th GSLV launch since 2001
• 2nd GSLV Mk.2 launch since 2010
• 41st Indian space launch since 1979
• 24th geostationary communications satellite launched by ISRO

1038 GMT (5:38 a.m. EST)
 T-minus 10 minutes. At the time of launch, the GSLV will weigh 414 metric tons, or about 912,000 pounds. It will fly southeast fr om the Satish Dhawan Space Center, a facility on Sriharikota Island about 50 miles north of Chennai on India's east coast.
The payload for this launch is GSAT 14, a 4,369-pound Indian communications satellite. GSAT 14 will extend India's Ku-band and C-band communications capacity with 12 transponders, along with a pair of Ka-band beacons for frequency attenuation studies.
After three orbit-raising maneuvers with its on-board engine and deployment of its solar panels and two antennas, the satellite will be positioned in geostationary orbit at 74 degrees east longitude for a 12-year mission.
GSAT 14 will be positioned near other Indian satellites, such as INSAT 3C, INSAT 4CR and Kalpana 1, according to ISRO. The spacecraft also carries several technological experiments, including a fiber optic gyroscope, an active pixel sun sensor and new types of thermal coatings.
         
1033 GMT (5:33 a.m. EST)
 T-minus 15 minutes. Unlike many rockets utilizing strap-on boosters, the GSLV's first stage is powered by a core solid-fueled motor and four liquid-fueled booster engines. The rocket will generate a total thrust of more than 1.5 million pounds at liftoff.
The S139 core motor and Vikas engines on the boosters will jettison and two-and-a-half minutes after liftoff, yielding to the GSLV's second stage Vikas engine for a more than two-minute burn, during which the rocket's 11.1-foot-diameter metallic payload fairing will fall away.
The third stage will ignite for a 12-minute burn before releasing the GSAT 14 spacecraft in an orbit with a low point of about 180 kilometers, or 111 miles, a high point of 35,975 kilometers, or 22,353 miles, and an inclination of 19.3 degrees. See more details on the GSLV's flight sequence in our launch timeline.
          
1029 GMT (5:29 a.m. EST)
 The mission director has authorized the launch of the GSLV.
          
1028 GMT (5:28 a.m. EST)
 T-minus 20 minutes. Today is the second launch attempt for the GSLV-D5 mission following an Aug. 19 countdown which was aborted 75 minutes before liftoff due to a fuel leak in the rocket's second stage.
The leak of toxic hydrazine fuel was blamed on cracks in the second stage fuel tank, which was made of an aluminum-zinc alloy known as Afnor 7020. The Indian launch team rolled the GSLV back to the vehicle assembly building at the Satish Dhawan Space Center to be taken apart and refurbished.
Engineers replaced the first and second stages of the GSLV after the Aug. 19 launch attempt. The new second stage has a fuel tank made of a different aluminum-copper alloy named AA2219.
ISRO also changed out electronic components inside the GSLV's four liquid-fueled strap-on boosters damaged by the fuel leak and subsequent cleaning with water. The third stage and GSAT 14 spacecraft were inspected and tested during the fall and found to be ready for launch.
          
1022 GMT (5:22 a.m. EST)
 We are now streaming live video from India's Satish Dhawan Space Center, wh ere all launch preparations are on track for liftoff in 26 minutes.

1046 GMT (5:46 a.m. EST)
T-minus 2 minutes. The GSLV's four L40H strap-on boosters will fire their Vikas engines at T-minus 4.8 seconds, giving the engines time to ramp up to full power of 150,000 pounds of thrust.

Ignition of the launcher's S139 solid-fueled core stage occurs as the countdown clock hits zero, followed immediately by liftoff.

The countdown is under the control of a computerized automatic sequence.
1045 GMT (5:45 a.m. EST)
T-minus 3 minutes. A check of the weather conditions show all parameters are acceptable for launch.
1043 GMT (5:43 a.m. EST)
T-minus 5 minutes.
