NASA poised to launch first Sun-skimming spaceship

  • NASA calls this mismatch “the coronal heating problem,” and hopes the Parker Solar Probe will solve the mystery of why the corona reaches temperatures of up to 10 million degrees Fahrenheit
  • Speeding by at a pace of 430,000 miles per hour will make it “the fastest human-made object

TAMPA: NASA is poised to launch a $1.5 billion spacecraft on a brutally hot journey toward the Sun, offering scientists the closest-ever view of our strange and mysterious star.
After the Parker Solar Probe blasts off from Cape Canaveral, Florida on August 11, it will become the first spacecraft ever to fly through the Sun’s scorching atmosphere, known as the corona.
Understanding how the corona works will help scientists anticipate dangerous space weather storms, which can disrupt the power grid on Earth.
“It’s of fundamental importance for us to be able to predict space weather much the way we predict weather on Earth,” explained Alex Young, a solar scientist at NASA.
The corona is a “very strange, unfamiliar environment for us.”

The unmanned probe is named after Eugene Parker, the 91-year-old pioneering solar astrophysicist, and the US space agency has coined it as the first mission to “touch the Sun.”
It will actually skim by at a distance of 3.83 million miles (6.16 million kilometers) above the Sun’s surface.
Mission managers say that may sound like a lot but is really quite a close shave, given the sweltering conditions out there.
The Sun-facing side of the probe will endure temperatures of about 2,500 degrees Fahrenheit (1,370 Celsius).
The spacecraft is protected by a heat shield that will keep it closer to room temperature, about 85 degrees Fahrenheit.
Speeding by at a pace of 430,000 miles per hour will make it “the fastest human-made object,” said project scientist Nicky Fox of the Johns Hopkins University Applied Physics Lab.
Over the course of its seven year mission, the spacecraft aims to pass through the corona 24 times, which Fox said makes for an “incredibly daring journey.”

Unlike a campfire, which feels hottest at the source, the heat from the Sun gets more intense further away from its surface.
“As we go from the surface of the Sun, which is 10,000 degrees Fahrenheit, and move up into the corona, we find ourselves quickly at millions of degrees,” he said.
NASA calls this mismatch “the coronal heating problem,” and hopes the Parker Solar Probe will solve the mystery of why the corona reaches temperatures of up to 10 million degrees Fahrenheit.
Fox said scientists have already studied the corona “every way imaginable,” and a closer look is now needed.
“We need to get into this action region, where all of these mysteries are actually occurring.”

The probe is protected by a 4.5-inch-thick (11.43-centimeter) carbon-composite shield, built to withstand 500 times the Sun’s radiation on Earth.
A series of instruments on board the spacecraft will measure the magnetic and electric fields, plasma waves and high energy particles.
There is also a white light imager, taking pictures of what the spacecraft is about to “plow through,” said Fox.
“The goal is to have the instruments on all the time but the prime science gathering for us is about 11 days,” she told reporters ahead of the launch.
A 45-minute launch window opens on Saturday at 3:48 am (0748 GMT).
Awaiting liftoff, the car-sized probe is already packed on to the Delta IV-Heavy rocket at Cape Canaveral Air Force Station in Florida.


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.
