ISRO GSLV D5 Will Launch On 27 Dec 2013

THE flight lest of rejuvenated Geo-synchronous Satellite Launch Vehicle(GSLV-D5) with indigenous cryogenic engine is likely to take place on January five from the space port of Sriharikota in Andhra Pradesh. Indian Space Research Organisation said.

ISRO's Mission Readiness Review (MRR) team will meet on December 27 to take a final call on the launch of GSLV-D5. Its mission was aborted at the 1 Ith hour on August 19. this year due to u fuel leak in its second stage.

"We have targeted the launch on January 5 afternoon; MRR team will meet on December 27 to take stock of the readiness and will finalise lite date and time for the launch." ISRO spokesperson told PTI. GSLV-D5 will put the communications satellite GSAT-14 into orbit. It Will be decide on the launch." The launch of GSLV-D5 scheduled ai 1650 hours on August 19 from Space Centre (SDSC) al Sriharikota. was called off afier a leak was detected in the fuel system of the liquid second stage in pre-launch pressurisation phase on the vehicle, just two hours before lift-off.

The propellanis were later drained from the cryogenic stage, liquid second stage and the four liquid strap-ons of GSLV-D5 and the vehicle was moved hack to the Vehicle Assembly Building in SDSC.

Fuel tank made ol aluminium alloy called Afnor 7020 tended to develop crack over a period of time and the leak was blamed on it.

Mangalyaan travels beyond Earth's influence

Mangalyaan travels beyond Earth's influence

INDIA'S maiden mission to Mars has traversed beyond the sphere of influence (SOI) of Earth extending aboul 9.25.000 km in its 10-momh long voyage lo the red planet.

The spacecraft crossed the SOI of Earth at around 1:14 hrs (1ST) on Wednesday. Indian Space Research Organisation (ISRO) said.

The Mars orbiter spacecraft had slune out of its earth-bound orbit in the early hours of December one during the critical 22-minute Trans Mars Injection, a manoeuvre hilled as the "mother of all slingshots."

The spacecraft which was in a hyperbolic orbit had escaped from the SOI. after the first step on Sunday in the Mars mission's 680 million-km-long odyssey to its destination to put on course the country's first ever inter-planetary space rendezvous. ISRO has planned four mid-course corrections —around December 11, in April, August and on September 14 —in case of any deviation along its path to the Martian orbit before its expected arrival in the orbit of the Red planet in September 2014. The spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry. Tracking and Command Network (1STRAC) in Bangalore with support from Indian Deep Space Network (1DSN) amennae at Byalalu here. The Mars mission's success would catapult India into a small club, which included the US. Europe and Russia, whose probes have orbited or landed on Mars. ISRO's workhorse ISRO's PSLV C 25 had successfully injected the 1.350-kg 'Mangalyaan' Orbiier into ihe orbil around the earth in a textbook launch from the Satish Dhawan Space Centre at Sriharikota on November five.

ISRO to launch Mars mission on 5 Nov 2013

INDIA'S ambitious space mission 10 explore planet Mars would be launched on November 5 from the spaceport of Sriharikota. ISRO announced on Tuesday.

The Mars Orbiter Mission(MOM). 'Manga!van'. would now be launched onboard'PSLV C25 on November 5 at 14:36 hours from the first launch pad of Satish Dhawan Space Centre at Sriharikota. some SO km from here, an ISRO spokesperson said. 

ISRO had staled that the liming of the launch was 3:28 PM. Ina revised press release. ISRO said "the correct time of lift-off is 14:36 hrs 1ST on Tuesday. November 5. 2013."

A decision on the launch date was to be taken on October 19 but postponed to Tuesday in view of bad weather in the South Pacific Ocean.

The powerful XL version of the Indian Space Research Organisation's workhorse Polar Satellite Launch Vehicle (PSLV) would be used for the Rs 450 crore mission.

Primary objectives of the mission are to demonstrate India's technological capability to send a satellite to orbit around Mars and conduct meaningful experiments such as looking for signs of life, take pictures of the red planet and study Martian environment.

launch campaign has already commenced in Sriharikota from where the 1,350-kg MOM spacecraft is slated to be launched by the Rs 110 crore Polar Satellite Launch Vehicle.

The satellite will carry compact science experiment instruments, totaling a mass of 15 kg. There will be five instruments to study Martian surface, atmosphere and mineralogy, ISRO said.
After leaving the earth's orbit, the spacecraft will cruise in deep space for about ten months using its own propulsion system and will reach Martian transfer trajectory in September 2014. The spacecraft subsequently is planned to enter into a 372 km by 80,000 km elliptical orbit around Mars. The main theme of MOM appears to be to seek whether there is methane, considered a "precursor chemical" for life, on the red planet.

ISRO to launch crucial GSLV mission on 19 Aug 2013

ISRO to launch crucial GSLV mission on 19 Aug 2013

After the failure of first engine in GSLV-D3 mission, which could not place the GSAT-4 satellite in the orbit, ISRO will embark on a crucial GSLV mission using its own cryogenic engine.

GSLV-D5 consists of eight tonne thrust engine and 12.5 tonnes of propellants. This would be the first GSLV mission for ISRO in three years after the twin failures in 2010.

The Indian Space Research Organisation (ISRO) will embark on a crucial GSLV mission using iis own cryogenic engine, when GSLV-D5. carrying the 1.980 kg advanced communication Sateliie GSAT-14. lifts offal 1650 his on August 19 from the SDSC Centre at Sriharikota. about 100 km from here.

ISRO sources told UNI on Friday that the 29-hour countdown for the launch that would take place from the Second Launch I*ad would commence at 1150 hrs on August 18. "The vehicle was completely integrated with the launch pad and the umbilicals connected." the sources said. "Pre-checks arc going on smoothly...everything is going on as per schedule." the sources said.

exuding confidence of tasting success this time. During the final countdown the rocket would be filled with propcllanis.

This would be the first GSLV mission for ISRO in three years after the twin failures in 2010.

The First stage of the three stage GSLV vehicle comprises S125 solid booster with four liquid (L40) strap-ons. The Second stage (GS2) was liquid engine and the third stage (GS3) was the cryo stage.

On the modifications carried out in the second engine in the wake of the failure of the first engine in GSLV-D3 mission, which could not place the GSAT-4 satellite in the orbit, the sources said some connected sub-systems in the fuel booster turbo pumps were modified. 

A her ihe flight lest of India's own cryo engine failed on April 15,20!0. the nexi GSLV-F06 mission (using Russian cryo stage) to place GSAT-5P satellite on Christmas Day the same year was aborted after the vehicle veered off from the trajectory due to failure of connectors.

This would be the eight GSLV flight for ISRO. In all. ISRO had tasted success in four GSLV launches of the total seven missions it had carried out so far. The first three missions GSLV-Dl (GSAT-1). GSLV-D2 (GSAT-2) and GSLV-FOI EDUSAT (GSAT-3) were successful. The next mission of GSLV-F02 carrying INSAT-4C failed but the GSLV-F04 that carried INSAT-4CR was successful, before the twin failures in 2010.
