Bangalore, September 18: India's tryst with Mars will begin in November 2013 to explore the red planet's atmosphere and search for life-sustaining elements, a top space official said late Monday.

"We are scheduling to launch the Mars mission Nov 27, 2013 when the red planet will be closer to the earth for injecting our spacecraft into its elliptical orbit," Indian Space Research Organisation (ISRO) chairman K. Radhakrishnan told reporters here.

The Rs.470-crore Mars mission will demonstrate India's capability to send a spacecraft 55 million km away from earth and look for life-sustaining elements 500 km away from the Martian surface.

The Indian space agency plans to use a high-end rocket (PSLV-XL) to launch the 1.4-tonne Martian spacecraft from its Sriharikota spaceport, about 80 km northeast of Chennai, with nine instruments to study various aspects of the red planet.

"The Mars mission will make India join the elite club of five top nations comprising the US, Russia, Europe, China and Japan, with indigenous technology for a 300-day space voyage from the launch date," Radhakrishnan said.

"If we don't go Mars late next year, we may have to wait for another 27 months (two years & three months) to embark on such an ambitious mission when the earth and the red planet will be closer again," the top scientist pointed out.

As the fourth planet from the sun and smallest celestial object in the solar system, Mars is terrestrial with breath-taking valleys, deserts, craters and volcanoes in a thin atmosphere. Named after the Roman god of war, the red planet has many similarities with earth like the rotation period and seasonal cycles.

"As in the case of Chandrayaan-1, we will have to take the spacecraft first into the earth's orbit from 22,000 km to 200,000 km in stages using the propulsion system and fire the rocket's liquid apogee motor to push it into the Martian orbit after cruising about 300 days," Radhakrishnan observed.

In the run-up to the launch, the space agency plans to augment the ground support station such as the deep space network at Bylalu, about 40 km from this tech hub, and rope in other ground stations in the region.

"As there will be a 20-minute communication delay in receiving signals from the Martian orbiter, we need to have high radio frequency system in the spacecraft and adequate protection for the effective functioning of its digital instruments," the chairman noted.

For ensuring to have the launch on the D-day (Nov 27), the space agency plans to have the entire set-up in place by mid-October 2013

Mumbai, Jan 3: The Shiv Sena on Friday targeted the Centre by questioning the "efficacy" of the 2016 surgical strike and said the perception that it would demoralise Pakistani terrorists remained an "illusion" as Indian soldiers continue to get killed in terror attacks in Kashmir.

Accusing the Modi government of boasting about how Pakistan was straightened out after the surgical strike, the Sena sought to know whether it has really happened.

It also observed that troubled borders were not good for the country's well-being.

The Sena's remarks come in the wake of the death of an Army soldier from Maharashtra, Naik Sandip Raghunath Sawant, who was killed during a counter-insurgency operation in Jammu and Kashmir on Wednesday.

"The New Year did not begin on a positive note in Kashmir. Our jawan from Satara, Sandip Sawant, attained martyrdom in Kashmir along with two other soldiers. In the last one month, seven to eight jawans from Maharashtra were killed in the line of duty. The Maha Vikas Aghadi government in Maharashtra is not responsible for this," the Sena said in an editorial in party mouthpiece 'Saamana'.

The party also questioned whether the situation in Kashmir has improved after the surgical strike and abrogation of Article 370 provisions.

The party, however, maintained that scrapping Article 370 was a good move.

India had conducted the surgical strike on September 29, 2016, across the Line of Control (LoC) as a response to a terrorist attack on an Indian Army base in Uri sector of Jammu and Kashmir earlier that month.

Without naming the Centre, the Sena alleged, "Circulating news that only the Pakistanis were getting killed in Kashmir will not change the reality as tricolour-draped bodies of Indian soldiers, like Sawant, are reaching their respective villages."

"There is a bloodshed along the Kashmir border and mounting anger among the families of martyred jawans. The perception that surgical strike will demoralise Pakistani terrorists has turned out to be an illusion. In fact, the (terror) attacks have increased," it added.

The Uddhav Thackeray-led party accused the ruling BJP of boasting about straightening out Pakistan after the surgical strike.

"But has Pakistan been really straightened out? Rather Pakistan has been indulging in ceasefire violations along the LoC every day," it added.

The Shiv Sena also questioned the government's claim that the situation in Kashmir was under control after the nullification of Article 370.

"It is good that Article 370 was scrapped. Before that, surgical strike was carried out in Pakistan. But has the situation in Kashmir improved? The terror attacks continue. It's only that there is a control in reporting (these incidents)," it said.

The Sena also alleged that there was no clarity as to what was transpiring in Kashmir after the scrapping of Article 370 and only the media reports of soldiers sacrificing their lives have been coming out from that state

In a veiled attack on the BJP, its erstwhile ally, the Sena, also accused it of exploiting the surgical strike for political gains.

New Delhi, Feb 19: India will switch to the world's cleanest petrol and diesel from April 1 as it leapfrogs straight to Euro-VI emission compliant fuels from Euro-IV grades now - a feat achieved in just three years and not seen in any of the large economies around the globe.

India will join the select league of nations using petrol and diesel containing just 10 parts per million of sulphur as it looks to cut vehicular emissions that are said to be one of the reasons for the choking pollution in major cities.

Sanjiv Singh, Chairman of Indian Oil Corp (IOC) - the firm that controls roughly half of the country's fuel market, said almost all refineries began producing ultra-low sulphur BS-VI (equivalent to Euro-VI grade) petrol and diesel by the end of 2019 and oil companies have now undertaken the tedious task of replacing every drop of fuel in the country with the new one.

"We are absolutely on track for supplying BS-VI fuel from April 1. Almost all refineries have begun supplying BS-VI fuel and the same has reached storage depots across the country," he said.

From storage depots, the fuel has started travelling to petrol pumps and in the next few weeks all of them will only have BS-VI grade petrol and diesel, he said. "We are 100 per cent confident that fuel that will flow from nozzles at all the petrol pumps in the country on April 1 will be BS-VI emission compliant fuel."

India adopted Euro-III equivalent (or Bharat Stage-III) fuel with a sulphur content of 350 ppm in 2010 and then took seven years to move to BS-IV that had a sulphur content of 50 ppm. From BS-IV to BS-VI it took just three years.

"It was a conscious decision to leapfrog to BS-VI as first upgrading to BS-V and then shifting to BS-VI would have prolonged the journey to 4 to 6 years. Besides, oil refineries, as well as automobile manufacturers, would have had to make investments twice - first to producing BS-V grade fuel and engines and then BS-VI ones," he said.

State-owned oil refineries spent about Rs 35,000 crore to upgrade plants that could produce ultra-low sulphur fuel. This investment is on top of Rs 60,000 crore they spent on refinery upgrades in the previous switchovers.

BS-VI has a sulphur content of just 10 ppm and emission standards are as good as CNG.

Originally, Delhi and its adjoining towns were to have BS-VI fuel supplies by April 2019 and the rest of the country was to get same supplies from April 2020.

But oil marketing companies switched over to supply of BS-VI grade fuels in the national capital territory of Delhi on April 1, 2018.

The supply of BS-VI fuels was further extended to four contiguous districts of Rajasthan and eight of Uttar Pradesh in the National Capital Region (NCR) on April 1, 2019, together with the city of Agra.

BS-VI grade fuels were made available in 7 districts of Haryana from October 1, 2019.

Singh said the new fuel will result in a reduction in NOx in BS-VI compliant vehicles by 25 per cent in petrol cars and by 70 per cent in diesel cars.

The switchover, he said, is a tedious task as every drop of old, higher-sulphur content fuel has to be flushed out in depots, pipelines and tanks before being replaced by BS-VI.

"We are confident of disruption-free switchover to BS-VI supplies across the country," he said. "What we will be supplying is the best quality available anywhere in the world. You don't have any better fuel that is supplied in any part of the world. Perhaps our BS-VI fuel will be better than equivalent fuel in some parts of the US and Europe."

India adopted a fuel upgradation programme in the early 1990s. Low lead gasoline (petrol) was introduced in 1994 in Delhi, Mumbai, Kolkata and Chennai. On February 1, 2000, unleaded gasoline was mandated nationwide.

Similarly, BS-2000 (Euro-I equivalent, BS-1) vehicle emission norms were introduced for new vehicles from April 2000. BS-II (Euro-II equivalent) emission norms for new cars were introduced in Delhi from 2000 and extended to the other metro cities in 2001.

Benzene limits have been reduced progressively from 5 per cent in 2000 to 1 per cent nationwide. Lead content in gasoline was removed in phases and only unleaded gasoline is being produced and sold from February 1, 2000.

The octane number of gasoline signifies the improved performance of the engine. Loss in octane number due to phasing out of lead was made up by installing new facilities in the refinery and changes in refinery operation. RON (Research Octane Number) of gasoline for BS-2000 spec was increased to 88. This has over time been increased to 91.

Singh said sulphur reduction will reduce Particulate Matter (PM) emissions even in the in-use older generation diesel vehicles.

New Delhi, Feb 14: AAP convenor Arvind Kejriwal has invited Prime Minister Narendra Modi to his swearing-in ceremony scheduled to take place at the Ramlila Maidan on February 16, senior party leader Gopal Rai said on Friday.

Rai, the convenor of the Aam Aadmi Party's Delhi unit, said a letter was sent to the prime minister on Friday morning.

All seven Delhi MPs and eight newly-elected BJP MLAs have also been invited for the oath-taking ceremony, Rai told news agency.

No chief minister or political leaders from other states will be part of the event as it will be a "Delhi-specific" ceremony, Rai had said on Thursday.

Kejriwal, through front-page advertisements in newspapers, has urged Delhiites to attend his oath-taking ceremony as he is set to become the chief minister of Delhi for the third consecutive term.

Kejriwal will take oath as Delhi Chief minister along with his cabinet at Ramlila Maidan at 10 am on Sunday.
