GSLV-3D launch fails.



In a setback to India's space programme, GSLV D-3, the satellite launch vehicle showcasing its indigenous cryogenic technology, trailed off its designated course and went out of control shortly after lift-off from the spaceport on Thursday. The rocket, along with its two payloads -- satellites GSAT-4 and GAGAN -- crashed into the Bay of Bengal 293 seconds after launch.

The launch was key to India's space programme as it would have become the sixth nation to successfully deploy the cryogenic technology, joining US, Russia, Japan, China and France. The earlier five versions of the GSLV had Russia-supplied cryogenic engine. India's cryogenic upper stage (CUS) engine was meant to replace the Russian engines.

GSLV Rises, And Falls
4.27:00pm: GSLV-D3 soars into sky from Sriharikota spaceport at the end of 29-hr countdown
4.29:31: First stage separates
4.29:33: Stage two ignites
4.30:48: Heatshield separates
4.31:53: Isro loses contact with launch vehicle as it veers off course
4.32:04: Presumed ignition of cryogenic engine

What Went Wrong

* Failure still being analysed but possibly the two steering engines, which control the rocket's path, may not have ignited in the cryogenic stage

* ISRO chief not sure if main cryogenic engine ignited

Second Failure

* Out of six launches, this is the second time GSLV has failed

* This was first launch using indigenously made cryogenic engine

GSLV launch to make ISRO self reliant



India’s hunt for a satellite-based global positioning system is nearing its end. On April 15, a muchawaited GSLV launch will place in orbit a satellite with navigational features and will be followed by three more which will be part of Geo Augmented Navigational system (GAGAN) aimed at enhancing satellite signals to the levels needed for a GPS programme.

The launch will be the first part of a plan that eventually leads to an Indian regional navigational satellite system which is to be in place by 2014. When fully operational, it will cover the entire Indian landmass with an additional range of 1,500 km.

India to get second AWACS on Thursday


India will receive another Israeli-made Phalcon Airborne Early Warning and Control System (AWACS) on Thursday, giving it the second 'eye in the sky' for enhanced surveillance that would virtually cover the entire nation.

The second AWACS will arrive in Jamnagar in Gujarat and will be deployed in Agra, IAF officials said here today.

With the arrival of the second AWACS, officials said the IAF can keep an eye on both the eastern and western front at the same time.

"After the induction of the third system, we would be able to virtually cover the whole nation at one go," they added.

The system, primarily used for detection of incoming hostile cruise missiles and aircraft from hundreds of kilometers away, can also direct air defence fighters during combat operations against enemy jets. It also helps detect troop build up across the borders.

Merchant ship collides with Coast Guard vessel, no casualties but Coast guard vessel sink

A merchant ship collided with an Indian Coast Guard vessel off the Mumbai Coast but no one was injured.

The mishap occurred around 5 pm near the Mumbai Port when the merchant ship rammed into a stationary Coast Guard vessel undergoing repair, Deputy Commissioner of Police (Port Zone) M Kohe said.

He said 59 people, all crew members of Coast Guard Ship Vivek, were rescued or swam to safety. The cause behind the collision involving merchant ship 'Global Purity' was being investigated.

Kohe said the Coast Guard ship developed cracks because of the impact, tilted on one side and began sinking. ICGS Vivek was a 20 year-old platform inducted into the Coast Guard on August 19, 1989.

Kohe said efforts were on to plug the cracks in the Coast Guard ship and pump out the water gushing inside.

An FIR has been lodged with the Yellow Gate police station in south Mumbai and investigation is on, he said.

The 74x12 m Coast Guard vessel was anchored when the merchant ship crashed into it.

India to have clauster bomb...

The other hunter killer that the Indian Air Force (IAF) is acquiring is CBU-105, considered the world's smartest cluster bomb. There has been tremendous opposition to it because of the collateral damage cluster bombs are known to cause. But sources told Headlines Today that this bomb is really smart - if a CBU-105 fails to locate its target, it self destructs.

Consider this - a column of Pakistani tanks rumble towards the Indian border, ready to blast their way into the country. The Indian border defences watch in horror as the Pakistani tanks approach. Then B-52 aircraft flies in and drops a CBU-105 bomb. A single bomb releases several small bomblets which identify their individual targets destroying them almost simultaneously.

The air force's most intelligent tank-killing weapon disintegrates freeing bombs from the main CBU-105 unit. Each bomblet, fitted with geared with a laser sensor, is a tiny little hunter-killer in its own right. Once the tank target is acquired, the fireworks begin. A tiny copper warhead is blasted with explosive energy downward. The tank doesn't even know what has hit it.

The IAF will be the first foreign user of the American cluster bomb, the world's most blisteringly intelligent anti-tank weapon. It is called the bomb with brains and has been used only once in anger before.
