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.

Feb 2: The Philippines on Sunday reported the first death from a new virus outside of China, where authorities delayed the opening of schools in the worst-hit province and tightened quarantine measures in a city that allow only one family member to venture out to buy supplies.

The Philippine Department of Health said a 44-year-old Chinese man from Wuhan was admitted on Jan. 25 after experiencing a fever, cough, and sore throat. He developed severe pneumonia, and in his last few days, “the patient was stable and showed signs of improvement, however, the condition of the patient deteriorated within his last 24 hours resulting in his demise.”

The man’s 38-year-old female companion, also from Wuhan, also tested positive for the virus and remains in hospital isolation in Manila.

President Rodrigo Duterte approved a temporary ban on all travelers, except Filipinos, from China and its autonomous regions. The U.S., Japan, Singapore and Australia have imposed similar restrictions despite criticism from China and an assessment from the World Health Organization that they were unnecessarily hurting trade and travel.

The death toll in China climbed by 45 to 304 and the number of cases by 2,590 to 14,380, according to the National Health Commission, well above the number of those infected in in the 2002-03 outbreak of SARS, or severe acute respiratory syndrome, which broke out in southern China and spread worldwide.

Meanwhile, six officials in the city of Huanggang, neighboring the epicenter of Wuhan in Hubei province, have been fired over “poor performance” in handling the outbreak, the official Xinhua News Agency reported.

It cited the mayor as saying the city’s “capabilities to treat the patients remained inadequate and there is a severe shortage in medical supplies such as protective suits and medical masks.”

After Huanggang, the trading center of Wenzhou in coastal Zhejiang province also confined people to homes, allowing only one family member to venture out every other day to buy necessary supplies.

With the outbreak showing little sign of abating, authorities in Hubei and elsewhere have extended the Lunar New Year holiday, due to end this week, well into February. The annual travel crunch of millions of people returning from their hometowns to the cities is thought to pose a major threat of secondary infection at a time when authorities are encouraging people to avoid public gatherings.

All Hubei schools will postpone the opening of the new semester until further notice and students from elsewhere who visited over the holiday will also be excused from classes.

Far away on China’s southeast coast, the manufacturing hub of Wenzhou put off the opening of government offices until Feb. 9, private businesses until Feb. 17 and schools until March 1.

With nearly 10 million people, Wenzhou has reported 241 confirmed cases of the virus, one of the highest levels outside Hubei. Similar measures have been announced in the provinces and cities of Heilongjiang, Shandong, Guizhou, Hebei and Hunan, while the major cities of Shanghai and Beijing were on indefinite leave pending developments.

Despite imposing drastic travel restrictions at home, China has chafed at those imposed by foreign governments, criticizing Washington’s order barring entry to most non-citizens who visited China in the past two weeks. Apart from dinging China’s international reputation, such steps could worsen a domestic economy already growing at its lowest rate in decades.

The crisis is the latest to confront Chinese leader Xi Jinping, who has been beset by months of anti-government protests in the semi-autonomous Chinese city of Hong Kong, the reelection of Taiwan’s pro-independence president and criticism over human rights violations in the traditionally Muslim northwestern territory of Xinjiang. Economically, Xi faces lagging demand and dramatically slower growth at home while the tariff war with the U.S. remains largely unresolved.

Among a growing number of airlines suspending flights to mainland China was Qatar Airways. The Doha-based carrier said on its website that its flights would stop Monday. It blamed “significant operational challenges caused by entry restrictions imposed by a number of countries” for the suspension of flights.

Oman also halted flights to China, as did Saudi Arabia’s flagship national carrier, Saudia.

Saudi Arabia’s state-run TV reported that 10 Saudi students were evacuated from Wuhan on a special flight. It said the students would be screened upon arrival, but did not say whether they would be quarantined for 14 days.

This weekend, South Korea and India flew hundreds of their citizens out of Wuhan. They went into a two-week quarantine.

On Sunday, South Korea reported three more cases for a total of 15. They include an evacuee, a Chinese relative of a man who tested positive and a man who returned from Wuhan. India reported a second case, also in southern Kerala state.

South Korea also barred foreigners who have stayed or traveled to Hubei province within the last 14 days from entering the country.

Indonesia flew back 241 nationals from Wuhan on Sunday and quarantined them on the remote Natuna Islands for two weeks. Several hundred residents protested the move, with one saying, “This is not because we do not have a sense of solidarity with fellow nationals. But because we fear they could infect us with the deadly virus from China.”

A Turkish military transport plane carrying 42 people arrived in Ankara from Wutan Saturday night. The 32 Turkish, six Azerbaijani, three Georgian nationals and an Albanian will remain under observation for 14 days, together with 20 personnel who participated in the evacuation, Health Minister Fahrettin Koca said.

Vietnam counted its seventh case, a Vietnamese-American man who had a two-hour layover in Wuhan on his way from the U.S. to Ho Chi Minh City.

The virus’ rapid spread in two months prompted the WHO on Thursday to declare it a global emergency.

That declaration “flipped the switch” from a cautious attitude to recommending governments prepare for the possibility the virus might spread, said the WHO representative in Beijing, Gauden Galea. Most cases reported so far have been people who visited China or their family members.

WHO said it was especially concerned that some cases abroad involved human-to-human transmission.

“Countries need to get ready for possible importation in order to identify cases as early as possible and in order to be ready for a domestic outbreak control, if that happens,” Galea told The Associated Press.

Both the new virus and SARS are from the coronavirus family, which also includes those that cause the common cold.

The death rate in China is falling, but the number of confirmed cases will keep growing because thousands of specimens from suspected cases have yet to be tested, Galea said.

“The case fatality ratio is settling out at a much lower level than we were reporting three, now four, weeks ago,” he said.

Although scientists expect to see limited transmission of the virus between people with family or other close contact, they are concerned about cases of infection spreading to people who might have less exposure.

Consumer watchdog Which? has claimed that more than one billion Android phones and tablets are vulnerable to hackers as they no longer supported by security updates.

According to the research report, the most at-risk phones are any that run Android 4 or older and those smartphones running Android 7.0 which can not be updated are also at risk.

Based on data from Google analysed by Which?, two in five android device users around the world are no longer receiving the important updates. Currently, those devices are unlikely to have issues, but the lack of security leaves them open to attack.

"It is very concerning that expensive Android devices have such a short shelf life before they lose security support, leaving millions of users at risk of serious consequences if they fall victim to hackers," Kate Bevan editor Which? said in a statement.

"Google and phone manufacturers need to be upfront about security updates with clear information about how long they will last and what customers should do when they run out. The government must also push ahead with planned legislation to ensure manufacturers are far more transparent about security updates for smart devices and their impact on consumers," Kate added.

Android phone released around 2012 or earlier, including popular models like the Samsung Galaxy S3 and Sony Xperia S, are particularly at risk to hackers.

Which? has made suggestions to Android users on what to consider if they have an older phone that may be at risk.

Any Android device which is more than two years old, check whether it can be updated to a newer version of the operating system. If it is on an earlier version than Android 7.0 Nougat, try to update via Settings> System>Advanced System update.

In case a user is not able tto update the phone, the device could be at risk of being hacked if it is running a version of Android 4 or lower.

A user also need to be careful about downloading apps outside the Google Play store and should also install a mobile anti-virus via an app.

London, Jan 11: Former cricketer Sachin Tendulkar's famous lap around the Wankhede Stadium after the World Cup 2011 win has been nominated in Laureas's list for the most inspiring sporting event in the last twenty years.

The moment featuring Tendulkar has been described as "Carried on the shoulders by a nation".

On his sixth attempt at the World Cup and with India not having won the competition since 1983, Tendulkar finally became a part of the team that lifted the coveted trophy. Carried on the shoulders of the Indian team, he made a lap of honour, shedding tears of joy after the victory was sealed in his home city.

The 2011 World Cup was also the first time, in which a host nation ended up winning the trophy.

Apart from Tendulkar, England's Andrew Flintoff is the only other cricketer to feature in the list. In 2005, England managed to defeat Australia in an Ashes Test, but Flintoff chose to first shake hands with Brett Lee rather than celebrate with his side.

Matthias Steiner (weightlifting), Natalie du Toit (swimming), Sky Brown (skateboarding), Alistair and Jonathan Brownlee (triathlon), Xia Boyu (mountaineering) have been nominated in the list.

Female tennis stars also feature in the list for coming up with an equal play, equal pay campaign. After pressure from Venus Williams and others, Wimbledon announced that female tennis players would receive prize money equal to the men's.

German international footballer Miroslav Klose was playing for Lazio in Italy's Serie A in 2012 against Napoli when he rose for a ball in the early moments of the game.

The ball came spiraling off his hand and skirted into the back of the net and a goal was awarded. While most players would carry on as if nothing had happened, Klose was honest with the referee and admitted that he handled the ball.

As a result, he also finds a place on the list.

The Laureus Sporting Moment Award celebrates the moments where the sport has unified people in the most extraordinary way.

This campaign has shortlisted 20 sporting stories from the last 20 years that have left their mark on the world.

The winner will be decided on the basis of public voting. It has already started, and the final date to cast the vote is February 16.

Finally, the result will be declared on February 17.
With three knock-out rounds, the top-20 moments will be whittled down to ten then five, with the top-five moments going head-to-head.
