Sept 27: US space agency Nasa on September 26 released high-resolution images of Chandrayaan-2 lander Vikram's intended landing site but said it was unable to determine the exact location of Vikram.

"Vikram had a hard landing and the precise location of the spacecraft in the lunar highlands is yet to be determined," a Nasa statement read.

The pictures were taken by a Lunar Reconnaissance Orbiter Camera (LROC) Quickmap fly-around of the targeted landing site.

"The lander, Vikram, was scheduled to touch down on September 6 at 4:24 pm Eastern Daylight Time. This event was India's first attempt at a soft landing on the Moon," the statement read.

The site was located about 600 kilometers (370 miles) from the south pole in a relatively ancient terrain.

"The Lunar Reconnaissance Orbiter (LRO) passed over the landing site on September 17 and acquired a set of high-resolution images of the area; so far the LROC team has not been able to locate or image the lander. It was dusk when the landing area was imaged and thus large shadows covered much of the terrain; the Vikram lander may be hiding in a shadow," Nasa said.

The agency added that the lighting will be favorable when LRO passes over the site in October and once again attempts to locate and image the lander.

After Vikram lost contact with ground stations, just 2.1 km above the touchdown site, the possibility of establishing contact with the lander had a deadline of September 21, because after that the region entered into a lunar night.

Isro had said the mission life of the Vikram lander and the Pragyan rover it carried will be one lunar day, which is equal to 14 Earth days.

The lunar nights can be very cold, especially in the south polar region where Vikram is lying. Temperatures could drop to as low as minus 200 degrees Celsius during the lunar night.

The instruments aboard the lander are not designed to withstand that kind of temperature. The electronics would not work in absence of solar energy and would get permanently damaged.

The Nasa orbiter passed over the Vikram landing site on September 17 and acquired a set of high-resolution images of the area; so far the LROC team has not been able to locate or image the lander.

“LRO will next fly over the landing site on October 14 when lighting conditions will be more favourable,” John Keller, Deputy Project Scientist Lunar Reconnaissance Orbiter Mission, Goddard Space Flight Centre, told PTI via email.

"It was dusk when the landing area was imaged and thus large shadows covered much of the terrain; it is possible that the Vikram lander is hiding in a shadow. The lighting will be favourable when LRO passes over the site in October and once again attempts to locate and image the lander," Nasa said.

New Delhi, Apr 21: The historic rout in oil markets that sent US crude prices plummeting to as much as minus USD 40 a barrel is unlikely to translate into any big reduction in petrol and diesel prices in India as domestic pricing is based on different benchmark, and refineries are already filled up to brim and cannot buy US crude just yet.

With storage capacity already overflowing amid coronavirus-induced demand collapse, traders rushed to to get rid of unwanted stocks triggering the collapse of US West Texas Intermediate (WTI) crude for May delivery.

Indian Oil Corp (IOC) Chairman Sanjiv Singh said the collapse was triggered by traders unable to take deliveries of crude they had previously booked because of a demand collapse. And so they paid the seller to keep oil in their storage.

"If you look at June futures, it is trading in positive territory... around USD 20 per barrel," he said.

Low oil prices may seem good in short-term but in the long run it will hurt the oil economy as producers will have no surplus to invest in exploration and production which will lead to a drop in production, he said.

He did not comment on retail fuel prices that have been static since March 16.

Oil companies have not changed rates despite a fall in international prices as they first adjusted them against the increase that was warranted from a Rs 3 per litre hike in excise duty and close to Re 1 per litre additional cost of switching over to cleaner BS-VI grade fuel from April 1.

Petrol in Delhi is priced at Rs 69.59 a litre and diesel comes for Rs 62.29 per litre.

"The negative price has no direct impact on India or Indian oil prices, as this has taken place due to crude oil produced and traded within the US. India's prices are driven partly by another benchmark, the Brent, which is still trading at USD 25/barrel. Therefore, the retail price of fuels in India are unlikely to fall," said Amit Bhandari, Fellow, Energy and Environment Studies, Gateway House.

Also, Indian refineries are already overflowing as fuel demand has evaporated due to the unprecedented nationwide lockdown imposed to curb spread of COVID-19. So, they can't rush to buy US crude.

The refineries have already cut operating rate to half because the fuel they produce has not been sold yet.

India imports 4 million barrels/day (1.4 billion barrels/year) of oil. The country has been benefitting from the falling prices of oil for the last five years, when oil dropped from a peak of USD 110/barrel to USD 50-60/barrel last year, enabling India to invest in public service programmes.

"However, the additional USD 30 fall of this week is good for India - but there is also a downside. If oil prices are too low, the economies of oil-rich gulf countries will be hurt, threatening the job prospects of the 8 million Indians working in the Gulf countries. India is the largest recipient of foreign remittances due to these workers – very low oil prices will hurt this cash stream," Bhandari said.

He said the negative price of oil shows how much oil oversupply exists in international markets today. "Global oil consumption has fallen due to the COVID-19 pandemic that traders are willing to pay customers to get rid of the barrels they can't store. The world does not have enough storage capacity, and dumping the oil is an environmental crime."

The first half of April saw Brent crude oil prices plummet 63.6 per cent to USD 26.9 per barrel. Prices of Western Texas Intermediate (WTI), the American oil, had also fallen similarly by 63.1 per cent.

But on April 20, WTI prices turned rapidly negative because traders on the Nymex exchange rushed to offload their May futures positions a day before expiry of contracts (on April 21).

Such WTI futures are traded on the Nymex exchange with contracts settled in physical crude oil. Problem is, those who had gone long are unable to find storage facilities for the oil and had to liquidate their contracts before expiry. This caused the plunge in WTI prices.

Contrast to this, June WTI Nymex futures prices is hovering around USD 21, while Brent for June delivery is at USD 25.

Miren Lodha, Director, CRISIL Research said the demand for crude oil was declining already because of economic slowdown when the COVID-19 pandemic-driven lockdowns crushed it further.

Consequently, oil demand is expected to contract by 8-10 million barrels per day (mbpd) in 2020 assuming demand recovery begins from the third quarter of the year, he said, adding if recovery doesn't happen by then, further demand destruction could occur.

On the supply side, producers reining in output following a strategic deal between OPEC members, Russia and the US.

Under this agreement, OPEC+ would reduce oil production by 9.7 mbpd for May and June, but gradually ease the curb to 7.7 mbpd between July and December 2020, and to 5.8 mbpd till April 2022 to stabilise prices.

"This is expected to reduce some surplus in the market by the end of 2020," Lodha said.

Crude oil demand is expected to decline by over 20 mbpd in April alone. Typically, monthly global demand is about 100 mbpd. Given this scenario, supply curbs would have limited influence.

Consequently, Brent oil prices is expected to be in the USD 25-30 range for the second quarter while increasing marginally in the last 2 quarters of 2020.

"The gigantic inventory build-ups and lack of storage facilities would also put pressure on prices," he said, adding overall Brent could average USD 30-35 in 2020, with a strong downward bias.

New Delhi, Jul 21: The Centre has written to all states and union territories warning against the use of N-95 masks with valved respirator by people, saying these don't prevent the virus from spreading out and are "detrimental" to the measures adopted for its containment.

The Director-General of Health Services in the Ministry of Health, in a letter to the Principal Secretaries of health and medical education of states, said it has been observed that there is "inappropriate use" of N-95 masks, particularly those with valved respirator, by the public other than designated health workers.

The DGHS referred to the advisory on the use of homemade protective cover for face and mouth available on the website of the Ministry of Health.

"It is to bring to your knowledge that the use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it does not prevent the virus from escaping out of the mask. In view of the above, I request you to instruct all concerned to follow the use of face/mouth cover and prevent inappropriate use of N-95 masks," DGHS Rajiv Garg said in the letter.

The government had in April issued an advisory on the use of homemade protective cover for face and mouth, asking people to wear it, particularly when they step out of their residences.

The advisory stressed such face covers must be washed and cleaned each day, as instructed and states that any used cotton cloth can be used to make this face cover. 

The colour of the fabric does not matter but one must ensure that the fabric is washed well in boiling water for five minutes and dried well before making the face cover. Adding salt to this water is recommended, it said.

It also listed the procedures of making such homemade masks, asking to ensure it fits the face well and there are no gaps on the sides.

It urges people to wash hands thoroughly before wearing the face cover,  switching to another fresh one as the face cover becomes damp or humid, and never reusing it after single use without cleaning it. 

"Never share the face cover with anyone. Every member in a family should have separate face cover," the advisory stated.
