World's first mission to touch the Sun lifts off

Washington, Aug 12: NASA's Parker Solar Probe, mankind's first mission to 'touch' the Sun, has been launched on Sunday on a seven-year-long journey to unlock the mysteries of our star's fiery outer atmosphere and its effects on space weather.

Liftoff took place from Space Launch Complex 37 at Cape Canaveral Air Force Station in the US early on Sunday.

The launch of the United Launch Alliance Delta IV Heavy rocket carrying the spacecraft was scrubbed yesterday due to a violation of a launch limit, resulting in a hold.

The car-sized spacecraft will travel directly into the Sun's atmosphere, about four million miles from its surface - and more than seven times closer than any spacecraft has come before, thanks to its innovative Thermal Protection System.

The USD 1.5 billion mission will perform the closest-ever observations of a star when it travels through the Sun's outer atmosphere, called the corona.

It will make 24 passes through the corona during its seven-year mission. The mission will rely on measurements and imaging to revolutionise our understanding of the corona and how processes there ultimately affect near-Earth space.

The Parker Solar Probe carries a lineup of instruments to study the Sun both remotely and in situ, or directly. Together, the data from these instruments should help scientists answer three foundational questions about our star.

A Sun-skimming mission like Parker Solar Probe has been a dream of scientists for decades, but only recently has the required technology - like the heat shield, solar array cooling system, and fault management system - been available to make such a mission a reality.

Parker Solar Probe will explore the corona, a region of the Sun only seen from Earth when the Moon blocks out the Sun's bright face during total solar eclipses.

The corona holds the answers to many of scientists' outstanding questions about the Sun's activity and processes.

Mumbai, Mar 9: The mayhem in domestic stock markets deepened with the BSE Sensex falling over 2,400 points and the Nifty50 trading below 10,400 points.

The plunge in the domestic indices was in line with the global markets on persistent fears of economic impact of the coronavirus epidemic.

Stocks of Reliance Industries registered the biggest fall in over 10 years as it fell to Rs 1,094.95 per share. At 1.34 p.m., it was trading at Rs 1,100, lower by Rs 170.05 or 13.39 per cent from its previous close. The stock fell most since October 2008.

The benchmark index of BSE Sensex was trading at 35,232.67 points, lower by 2,343.95 points or 6.24% from the previous close of 37,576.62 points. 

It had opened at the intra-day high of 36,950.20 and has so far touched a low of 35,109.18.

The Nifty50 on the National Stock Exchange was trading at 10,314.25 points, lower by 675.20 points or 6.14% from the previous close. 

It was a sell-off across sectors, led by financial, metal, energy and IT stocks - which weighed on the markets.

Further, crude oil prices also slumped around 30% on Monday as Organization of Petroleum Exporting Countries (OEPC) failed to agree on an output cut deal, eventually causing Saudi Arabia to cut its prices as it is likely to increase its production. Saudi Arabia's stance has already raised concerns of an all-out price war.

Brent crude futures are currently trading around $34 per barrel.

On Saturday, Saudi Arabia announced massive discounts to its official selling prices for April, and the nation is reportedly preparing to increase its production above the 10 million barrel per day mark, according to reports.

As per analysts, the oil market witnessed the worst price fall on Monday since the 1991 Gulf War.

Dubai, Jul 29: Muslim pilgrims on Wednesday begin the annual Haj, downsized this year as the Saudi hosts strive to prevent a coronavirus outbreak during the five-day pilgrimage.

The Haj, one of the five pillars of Islam and a must for able-bodied Muslims at least once in their lifetime, is usually one of the world's largest religious gatherings.

But this year only up to 10,000 people already residing in the Kingdom will participate in the ritual, a tiny fraction of the 2.5 million pilgrims from around the world that attended last year.

"There are no security-related concerns in this pilgrimage, but (downsizing) is to protect pilgrims from the danger of the pandemic," said Khalid bin Qarar Al Harbi, Saudi Arabia's director of public security.

Pilgrims will be required to wear masks and observe social distancing during a series of religious rites that are completed over five days in the holy city of Makkah and its surroundings in western Saudi Arabia.

Those selected to take part in the Haj were subject to temperature checks and placed in quarantine as they began trickling into Makkah at the weekend.

State media showed health workers sanitising their luggage, and some pilgrims reported being given electronic wristbands to allow authorities to monitor their whereabouts.

Workers, clutching brooms and disinfectant, were seen cleaning the area around the Kaaba, the structure at the centre of the Grand Mosque draped in gold-embroidered cloth towards which Muslims around the world pray.

Haj authorities have cordoned off the Holy Kaaba this year, saying pilgrims will not be allowed to touch it, to limit the chances of infection.

They also reported setting up multiple health facilities, mobile clinics and ambulances to cater to the pilgrims.

Saudi authorities said only around 1,000 pilgrims residing in the Kingdom would be permitted for the Haj. Some 70 per cent of the pilgrims are foreigners residing in the Kingdom, while the rest will be Saudi citizens, authorities said.

All worshippers were required to be tested for coronavirus before arriving in the holy city of Makkah and will also have to quarantine after the pilgrimage as the number of cases in the Kingdom nears 270,000.

They were given elaborate amenity kits that include sterilised pebbles for a stoning ritual, disinfectants, masks, a prayer rug and the Ihram, a seamless white garment worn by pilgrims, according to a Haj ministry programme document.

"I did not expect, among millions of Muslims, to be blessed with approval," Emirati pilgrim Abdullah Al Kathiri said in a video released by the Saudi media ministry.

"It is an indescribable feeling... especially since it is my first pilgrimage."

The Haj ministry said non-Saudi residents of the Kingdom from around 160 countries competed in the online selection process but it did not say how many people applied.

Despite the pandemic, many pilgrims consider it safer to participate in this year's ritual without the usual colossal crowds cramming into tiny religious sites, which make it a logistical nightmare and a health hazard.

Beijing, Jun 11: Floods and mudslides in south China have uprooted hundreds of thousands of people and left dozens dead or missing, state media reported Thursday.

The bad weather has wreaked havoc on popular tourist areas that had already been battered by months of travel restrictions during the coronavirus outbreak.

Torrential downpours unleashed floods and mudslides that caused nearly 230,000 people to be relocated and destroyed more than 1,300 houses, official state news agency Xinhua reported, citing the Ministry of Emergency Management.

In southern Guangxi Zhuang Autonomous Region, six people were reported dead and one missing, Xinhua said.

Streets were waterlogged in popular tourist destination Yangshuo, forcing residents and visitors to evacuate on bamboo rafts.

The local government said more than 1,000 hotels had been flooded and more than 30 tourist sites damaged.

One owner of a family-run hotel told Xinhua that the guest rooms were submerged in one metre (three feet) of rainwater.

The extreme weather has dealt a hefty blow to the region's tourism sector, which is still reeling from the COVID-19 epidemic.

The emergency management ministry said there were direct economic losses of over 4 billion yuan (more than $550 million) from the flooding, Xinhua reported.

In Hunan Province, at least 13 people were killed in rain-triggered disasters, and another eight people are missing or killed in southwestern Guizhou province, according to the local emergency response departments, Xinhua said.

The heavy downpours began at the beginning of June and have led to "dangerously high water levels" in 110 rivers, Xinhua reported.

Further rainstorms are expected in the next few days across the south.
