Concerns Over Debris Left By ASAT Missile Before ISRO’s April 1 Launch

Concerns Over Debris Left By ASAT Missile Before ISRO's April 1 LaunchISRO will launch the PSLV on April 1 carrying multiple payloads.NEW DELHI: 

Will India’s recent test of the anti-satellite (ASAT) missile endanger the launch of the Polar Satellite Launch Vehicle tomorrow? The anti-satellite weapon launched as part of Mission Shakti created a new debris pile some 300 kilometres above the Earth.

When the PSLV is launched from Sriharikota, it will have to traverse through that debris belt where there would be a risk of collision.

Using a new rocket part of the ballistic missile defence system on March 27, India shot down the over-700 kilogram MicroSAT-R satellite at an altitude of 300 kilometres, creating a debris pile of some 300 pieces.

The whole operation was completed in three minutes after the killer missile was launched from Dr Abdul Kalam Island off the coast of Odisha by scientists of the Defence Research and Development Organisation or DRDO.

The ASAT missile can bring an enemy nation to a halt by disrupting communication systems.

The big question that needs some introspection as the Indian Space Research Organisation (ISRO) gets ready for the PSLV launch is – what are the risks from this new debris that India itself has created? And does ISRO have a plan to mitigate this new threat?

Experts say that at 300 kilometres, the very high speed collision of two man-made objects would generate a lot of space debris and they would certainly come in the way of future launches at least for the next several weeks.

India is launching a satellite tomorrow, six days after the orbital collision. This too is another satellite belonging to the DRDO. Thus, there are concerns of whether the DRDO, by carrying out Mission Shakti, has endangered its own satellite called EMISAT.

“Yes, theoretically, that is right. But you should understand that today in space, millions of debris are floating around. Every satellite launch leaves anything between 100-150 fragments, they could be small bolts, they could be heat shields, they could be anything,” VK Saraswat, former DRDO head and member of the government think tank NITI Aayog told NDTV.

“These fragments keep floating around because as soon as you get out of atmosphere, nothing comes back; it always remains there and keeps on revolving because it is at the same speed of the satellite. So when they keep revolving they have a tendency to come in the way of other objects that are going to be propelled. That is why internationally there is a programme today to remove debris as much as possible and India is a signatory to that,” he said.

“Launching an anti-satellite missile does not create even 50 per cent of what we are doing while launching a large satellite, so it is not that we are going to increase by… suppose we have created 10 or 50 or 60 debris elements, one lakh or one million have become that much extra,” Mr Saraswat said.

On its part, before any launch, the ISRO does look out for space debris and on this occasion it would be more vigilant. “Collision avoidance is a standard procedure and on this launch at Sriharikota we will be extra cautious,” said Vivek Singh, ISRO assistant scientific secretary.

On several occasions when ISRO’s collision avoidance team has detected a threat of debris coming in the path of the rocket as it lifts off from Sriharikota, the launch has been postponed by a few minutes to ensure that the vehicle gets a clear path.

To track space debris, recently ISRO put in place a special multi-object tracking radar at Sriharikota. In addition, Indian space scientists depend on public domain information on space debris and situational awareness made available by the American armed forces.

Under normal circumstances, using these sophisticated radars the ISRO monitors space debris over the space port and on this occasion, sources say they are going to take abundant precautions.

India Successfully Test-Fires Agni-5 Ballistic Missile: All You Need To Know

India Successfully Test-Fires Agni-5 Ballistic Missile: All You Need To Know

ICBM Agni-V is most advanced missile in the Agni series.

India successfully test-fired nuclear capable surface-to-surface Agni-5 Ballistic Missiletoday, boosting indigenous missile capabilities and deterrence strength of the country. Agni-5 is the most advanced missile in the Agni series with a strike range of over 5,000 kilometres. Agni-5 was test-fired at about 9:54 am from launch pad number 4 of the Integrated Test Range (ITR) in Abdul Kalam Island, earlier known as Wheeler Island, off Odisha coast. During the test-fire, the sophisticated missile travelled for 19 minutes and covered 4,900 km. With the first testing of Agni-5, India had become a part of the super-exclusive club of countries with ICBMs or inter-continental ballistic missiles in 2012.
Here are 10 Facts about Agni-V Ballistic Missile:
  1. Agni-5 is most advanced missile in the Agni series with new technologies incorporated in it in terms of navigation and guidance, warhead and engine. It has a range of over 5,000 km.
  2. The redundant Navigation systems, very high accuracy Ring Laser Gyro based Inertial Navigation System (RINS) and the most modern and accurate Micro Navigation System (MINS) had ensured the missile reached the target point within few metres of accuracy, said an official of Defence Research and Development Organization (DRDO).
  3. After four successful developmental trials, this was the first user associate test of Agni-5 missile, sources said.
  4. Agni-5 missile has a high speed on-board computer and fault tolerant software along with robust and reliable bus. Its path is precisely directed by the advanced on-board computer and inertial navigation system.
  5. The three-stage, 17-metre tall, two-metre wide Agni-5 missile is capable of carrying a nuclear warhead of about 1.5 tonnes.
  6. The missile so programmed that after reaching the peak of its trajectory it will turn towards Earth to continue its journey towards the intended target with an increased speed due to the attraction of the earth s gravitational pull, DRDO official said.
  7. The first two successful flights of Agni-5 missile in 2012 and 2013 were in open configuration. Agni-5 has higher reliability, longer shelf life, less maintenance and enhanced mobility.
  8. At present, Agni series missiles that India has in its armoury are: Agni-1 with 700 km range, Agni-2 with 2,000 km range, Agni-3 and Agni-4 with 2,500 km to more than 3,500 km range.
  9. The first test of Agni-5 was conducted on April 19, 2012, the second on September 15, 2013, the third on January 31, 2015 and fourth trial on December 26, 2016 from the same base.
  10. With testing of Agni-5, India had become a part of the super-exclusive club of countries with ICBMs or inter-continental ballistic missiles after US, Britain, Russia, China and France.

As a member of MTCR, India can also buy predator drones from the us
US has successfully used to drones to kill Taliban leaders in Afghanistan
India is in all likelihood to go into the Missile generation manipulate Regime or the MTCR this week — aflow with the intention to help her export hello-tech missiles to other international locations andpurchase predator drones from the us.

reports say an announcement may also happen for the duration of high Minister Modi’s visit to the usthis week, so that you can be great

The drones have been used successfully by means of the united states to kill Taliban leaders in Afghanistan.

India had implemented for membership to the MTCR remaining yr but has confronted sturdy oppositionfrom some countries.

The Barack Obama management has strongly backed India’s club to MTCR and 3 other export manageregime — the Australia institution, Nuclear providers group and the Wassenaar arrangement.

mounted in 1987, the voluntary MTCR goals to limit the spread of ballistic missiles.

India is also aggressively pushing to come to be as member of the Nuclear suppliers organization, that isconsidering new packages at a assembly next week.

WASHINGTON: India may join the Missile technology manipulate Regime (MTCR) “right away‘ as there are not any principal limitations and things are transferring positively, a senior US reliable has said.

“We do assume that India will be a part of MTCR right away. I assume matters are shiftingundoubtedly,” a senior Obama administration legit told Press accept as true with of India when askedabout the opportunity of India joining the 34-member institution.

“There are no longer any foremost barriers that we are aware about,” the official said the day past.

US President Barack Obama has strongly subsidized India’s membership into the MTCR and 3 differentexport control regime – Australia group, Nuclear suppliers organization and the Wassenaar association.

The circulate will boost India’s efforts to buy Predator drones from the usa and export its excessive-tech missiles to pleasant countries.

however, on India turning into a member of Nuclear suppliers institution (NSG) wherein China isbrazenly opposing it, the Obama management is preserving its palms crossed for the moment.

“On NSG, there’s a system this is nevertheless ongoing. I do not assume the NSG plenary isn’t alwaysmeeting till later on this month. let’s see the way it goes but the US is actually, categorically, unreservedly committed to India’s membership in the NSG,” the reputable stated.

the usa and India and other pleasant nations are working actively together to peer that India get there,” the reliable, who asked anonymity, introduced.

established in April 1987, the voluntary MTCR goals to limit the spread of ballistic missiles and differentunmanned delivery systems that would be used for chemical, organic, and nuclear assaults.

The MTCR regime urges its 34 participants, which include most of the sector‘s key missile producers, torestriction their exports of missiles and related technologies able to wearing a 500-kilogramme payload at the least three hundred kilometres or delivering any sort of weapon of mass destruction.

on the grounds that 2008, India has been one of the five nations which might be Unilateral Adherents to MTCR.

After MTCR’s declaration, India and the usa are predicted to speedytune their discussion on sale of predator series of unmanned aircraft for the Indian military.
