‘Touch the sun’: NASA spacecraft hurtles toward our star

CAPE CANAVERAL, Florida: Embarking on a mission that scientists have been dreaming of since the Sputnik era, a NASA spacecraft hurtled Sunday toward the sun on a quest to unlock some of its mysteries by getting closer than any object sent before.
If all goes well, the Parker Solar Probe will fly straight through the wispy edges of the sun’s corona, or outer atmosphere, in November. In the years ahead, it will gradually get within 3.8 million miles (6 million kilometers) of the surface, its instruments protected from the extreme heat and radiation by a revolutionary new carbon heat shield and other high-tech wizardry.
Altogether, the Parker probe will make 24 close approaches to our star during the seven-year, $1.5 billion journey.
“Wow, here we go. We’re in for some learning over the next several years,” said Eugene Parker, the 91-year-old astrophysicist for whom the spacecraft is named.
It was Parker who accurately theorized 60 years ago the existence of solar wind — the supersonic stream of charged particles blasting off the sun and coursing through space, sometimes wreaking havoc on electrical systems on Earth.
This is the first time NASA has named a spacecraft after a living person.

As Parker and thousands of others watched, a Delta IV Heavy rocket carried the probe aloft, thundering into the clear, star-studded sky on three pillars of fire that lit up the middle-of-the-night darkness.
NASA needed the mighty 23-story rocket, plus a third stage, to get the Parker probe — the size of a small car and well under a ton — racing toward the sun, 93 million miles (150 million kilometers) from Earth.
A Saturday morning launch attempt was foiled by last-minute technical trouble. But Sunday gave way to complete success.
It was the first rocket launch ever witnessed by Parker, a retired University of Chicago professor. He said it was like looking at photos of the Taj Mahal for years and then beholding the real thing in India.
“I really have to turn from biting my nails in getting it launched, to thinking about all the interesting things which I don’t know yet and which will be made clear, I assume, over the next five or six or seven years,” Parker said on NASA TV.
Among the mysteries scientists hope to solve: Why is the corona hundreds of times hotter than the surface, which is 10,000 degrees Fahrenheit (5,500 degrees Celsius)? And why is the sun’s atmosphere continually expanding and accelerating, as Parker theorized in 1958?
“The only way we can do that is to finally go up and touch the sun,” said project scientist Nicola Fox of Johns Hopkins University. “We’ve looked at it. We’ve studied it from missions that are close in, even as close as the planet Mercury. But we have to go there.”
A better understanding of the sun’s life-giving and sometimes violent nature could also enable earthlings to better protect satellites and astronauts in orbit, along with the power grids so vital to today’s technology-dependent society, said Thomas Zurbuchen, NASA’s science mission chief.
Parker, the probe, will start shattering records this fall. On its very first brush with the sun, it will come within 15.5 million miles (25 million kilometers), easily beating the current record of 27 million miles (43 million kilometers) set by NASA’s Helios 2 spacecraft in 1976.
By the time Parker gets to its 22nd, 23rd and 24th orbits of the sun in 2024 and 2025, it will be even deeper into the corona and traveling at a record 430,000 mph (690,000 kilometers per hour). Nothing from planet Earth has ever gone that fast.
Even Fox has difficulty comprehending the mission’s derring-do.
“To me, it’s still mind-blowing,” she said. “Even I still go, ‘Really? We’re doing that?’“
The 8-foot (2.4-meter) heat shield will serve as an umbrella that will shade the spacecraft’s scientific instruments, with on-board sensors adjusting the protective cover as necessary so that nothing gets fried.
A mission to get up close and personal with our star has been on NASA’s books since 1958. The trick was making the spacecraft compact and light enough to travel at incredible speeds and durable enough to withstand the punishing environment.
“We’ve had to wait so long for our technology to catch up with our dreams,” Fox said.


Pakistan is rapidly becoming a “digital-first country”, Google

Pakistan is rapidly becoming a “digital-first country”, Google

  • Pakistan digital growth is supported by population and increasing penetration of internet, IT experts
  • Prime Minister’s Taskforce on IT and Telecom to meet next week to draw comprehensive policy

KARACHI: Destine to become the fourth fastest growing economy by 2030, Pakistan, supported by a growing population, fast growing business and increasing penetration of Internet, is poised to grab first position among the digital economies, Information Technology (IT) experts say.
US technology giant, Google, says Pakistan is quickly becoming a “digital-first country”, which means there are new opportunities for brands to reach and engage with consumers that may have previously been overlooked.
“It shows that Google has realized the marketing potential of the country and they are now encouraging businesses to focus on Pakistan as a potential market,” Badar Khushnood, vice president of growth at Fishry.Com and vice chairman of [email protected], commented.
According to Google, there are five reasons for “considering expanding your digital campaigns into Pakistan”.
Pakistan’s growing population is the first reason that makes the country attractive for the foreign and local investors to venture into the IT sector.
“Pakistan has a population of more than 202 million people, which means there are lot of potential consumers coming online every day. And the country is even more urbanized than neighboring India, with nearly 40 percent of total households living in cities,” writes Lars Anthonizen, head of large customer marketing, South Asia, Google.
Pakistan’s economy grew by 5.7 percent in fiscal year 2018. HSBC in is recent report published in September 2018 has projected Pakistan to become the fourth fastest growing economy by 2030.
Around 90 percent of the companies in the country are SMEs which are contributing more that 40 percent to the country’s 313 billion economy, according to the State Bank of Pakistan.
Third attraction, according to Google, is the country’s growing smart phone users. Pakistan has 152 million cellar subscribers, and 60 million 3G/4G subscribers, according to Pakistan Telecommunication Authority (PTA).
This number will likely grow quickly as smart phone prices have dropped over the last few years. Pakistan also has some of the cheapest data prices in the world, which is helping to grow mobile app usage, according to Google.
However, experts say more work is needed to be done to fully utilize the existing potential. “We need to work on optic fibers, penetration of 4G, creation of data centers, telecom infrastructure and most importantly creation of awareness among masses,” Pervaiz Iftikhar, a member of the newly formed prime minister’s Taskforce on IT and Telecom, told Arab News.
Pakistan’s overall Internet penetration stands at 29.9 percent with 62 million broadband subscribers, a fourth attraction for the investor, as per Google. In spite of this, digital consumption in the country continues to grow quickly. YouTube watch time, for example, has seen over 60 percent growth over the last three years.
The Chinese-Pakistan Economic Corridor (CPEC) is the largest Chinese investment venture in Pakistan with around $62 billion, a fifth reason to look toward Pakistan.
The mega project under BRI is not only limited to the infrastructure and energy sector but it is also contributing to the growth of the IT sector in Pakistan.
“One of the first CPEC projects is to lay 820 kilometers of fiber-optic cable, connecting more Pakistanis to the Internet. This is in addition to ongoing investments in 3G and 4G network expansions from China Mobile, and the company has already announced plans to invest another $225 million in 4G expansion (bringing its total investment to $2.4 billion),” writes Lars Anthonizen.
“We have to connect every village through fiber optics that will not only create thousands of jobs but would multiply opportunities for the IT business countrywide,” Pervaiz Iftikhar added.
“A lot of potential exists in the IT sector of Pakistan with the young population turning to computers, smart phones and other digital means, and the country offers big market for local and foreign investors”, Jehan Ara, another member of the prime minister’s Taskforce on IT and Telecom and president of [email protected], commented.
Badar Khushnood, who is also former consultant of Google, Facebook and Twitter, called for comprehensive policy for the growth of the IT sector.
“Taxation systems should be rationalized, simplified, and encouraging for startups. The country also needs data protection laws, and broader cyber laws,” he added.
The first meeting of the prime minister’s Task Force on IT and Telecom is expected to be held next week in Islamabad. “Comprehensive strategy including short term and long term measures would be discussed in the upcoming meeting of taskforce because country needs a policy for the persistent growth of IT and Telecom sector”, Pervaiz Iftikhar informed.
