‘India can defend its satellites'

Bangalore: India did not believe in space wars but had all the technology required to integrate systems to defend its satellites, V K Saraswat, Scientific Advisor to the Defence Minister, said Friday.

"Our country does not have a policy to attack anybody in space. We don't believe in it. But as part of the Ballistic Missile Defence Programme, we have all the technology elements which are required to integrate a system through which we can defend our satellites or take care of future requirements."

As a country, "we do not believe in space wars", he said in response to a query whether India had anti-satellite weapon capabilities.

India did not have a formal anti-satellite weapon policy of attacking satellites in space, but was well geared in case of any eventuality, he told reporters here.

Giving updates on the various defence programmes, he said the 'Nirbhay' project, relating to a subsonic medium range cruise missile, is undergoing integration and the first flight trial is expected early next year.

Discussing the Hypersonic cruise missile, he said it was one of the most complex technologies under development with only two countries -- US and Australia -- having done it so far. He said the engine for the missile had undergone a test of 20-second duration on the ground and had performed "reasonably well".

He expected that in early next year the flight test of Hypersonic Cruise Vehicle can be conducted in which they would be able to demonstrate the flight engine at an altitude of 30 kms.

Giving an update on Agni-V missile, he said all the rocket rotors, first stage, second stage and third stage have been developed. "We will ground test it," he said adding the software and hardware essential for control of guidance for a long-range missile is being developed.

"We expect that by end of this year we will have the first flight of Agni-V," he said.

good thing, please keep denying the project regarding our anti satellite capabilites. it should be kept under wrap.
 
DRDO and ISRO working on robust satellite programmes with many technologies for the armed forces. There is a project to defend satellites from evetual ASAT missiles. As well as sats for ELINT, COMINT, surv and recon.

When we have BMD its easier to develop ASAT but this move will be against India's long standing against weaponization of space as Dr. Saraswat told.

India can't declare that we have ASAT missiles according to its long standing policy and UN declaration. Of course China also had similar policy and wanted to test the ASAT under secrecy, but couldn't thanks to NORAD.

DRDO has done ground simulations of ASAT missiles but they will never test it in real against satellite until special situation arises. They said its upto the govt to decide.

to knock down a low orbiting satellite ,we need a missile like agni-2.
 
Guys what kind of hypersonic programme does Australia has........
anyone got any info????
 
All these are bull$#it..
Get up DRDo..
test ASAT..soon...
Space is the next place for war..

U guys will never learn...
 
australia is developing hypersonic scramjet technology for commercial use!!...not military!!!!

Human travellings at Mach 7 speed:cheesy:
passengers life at risk..
a small snag will kill all those people..

Traveling at mach 7...

I would prefer normal jet airways..
 
well NASA thinks it's possible

Nasa to develop 'hypersonic' jets that travel at 5 times the speed of sound

NASA is planning to build hypersonic jets that will fly through the Earth’s atmosphere and slash flight times around the world to a few hours at most.

The US space agency wants to manufacture a craft that would travel at five times the speed of sound and bring in a new age of aircraft akin to a turbo-charged Concorde.

Travelling at such speed would reduce the flight time from New York to Sydney to around two-and-a-half hours, from the 21 hours it is now.

The project is thought to be aimed at making a reusable aircraft that could fly to Mars but, as with previous space technology, it could have a huge impact upon passenger transport too.

Under the NASA Aeronautics 2010 proposal, the space agency will allocate $5million per year for the next three years to make the new aircraft a reality.

The aim is to create something which can carry passengers through the atmosphere, descend and land safely before being reused.

According to the proposal, engineers will look into ‘entry, descent and landing of high-mass vehicles entering into planetary atmospheres’ and ‘airbreathing access to space’

NASA is also aware of the many challenges it faces to build such a machine.

The proposal says: ‘The hypersonic heating environment, coupled with the emphasis on reusability, creates additional severe technology challenges for materials, material coatings, and structures that not only carry the aerodynamic loads of the air but also repeatedly sustain high thermal loads requiring long-life and durability while minimizing weight.

‘Space access launch vehicles must be lightweight, fully reusable and easily maintained if low-cost access to space is to be achieved.’

Hypersonic aircraft is still a fairly new concept and follows on from Concorde, which flew at Mach 2, or twice the speed of sound.

A hypersonic aircraft would reach Mach 5, or five times the speed of sound.

In June this year an experimental scramjet aircraft set a record for hypersonic flight, blazing through the air for more than three minutes at Mach 6, or more than 4,500 mph.

The X-51A Waverider scramjet was released from a B-52 bomber last week before its engine took it to Mach 6 and it flew autonomously for 200 seconds.

Scramjets work by using oxygen rushing in through the engine at supersonic speeds to ignite hydrogen fuel.

In October Richard Branson’s Virgin Galactic SpaceShipTwo completed its solo maiden flight after being carried aloft by its mothership to an altitude of 45,000ft and released over the Mojave Desert.

Built by famed aircraft designer Burt Rutan, the craft aims to be the first opportunity for space tourism at something close to an affordable price - tickets cost $200,000 (£125,000).

The craft is based on a prototype that won a $10million (£6.3million) prize in 2004 for being the first manned private rocket to reach space.

The six-passenger ship will undergo rigorous testing before it can carry tourists to space.

I think Shourya type missile will be enough. If a PDV can carry a anti-ballistic kill vehicle to 150 km altitude than Shaurya shall be able to carry anti-Sat kill vehicle upto 600 km altitude. Also note that ASAT kill vehicle is simpler than ABM kill vehicle. Satellite movement, orbit, trajectory, velocity are almost constant and lightly shielded unlike ballistic missiles.
 
when humans travel at Mach 7,won't it pull high pressure and does it stop our blood from flowing some thing like that...
even fighter jets wont go mach 4

I think nothing will happen if the aircraft reach Mach 7 in a slow and steady manner. There is something called inertial frame of reference. People will not be even aware that the aircraft moving at Mach 7! :D
