'Touch the sun': NASA spacecraft hurtles toward our star

Space agency Nasa postponed the launch of a satellite set to fly into the sun's atmosphere, or corona.
NASA managers have cleared the $1.5 billion Parker Solar Probe for launch early Saturday on a daring mission to "touch the sun". He proposed the existence of solar wind - a steady, supersonic stream of particles blasting off the sun - 60 years ago.
The powerful Delta 4 Heavy and a solid-propellant upper stage will provide the energy needed to counteract Earth's 18-mile-per-second orbital velocity, allowing the Parker Solar Probe to fall into the inner solar system. This image made available by NASA shows an artist's rendering of the Parker Solar Probe approaching the Sun.
The launch countdown was halted with just one-minute, 55 seconds remaining, keeping the Delta IV (four) rocket at Cape Canaveral, Florida, with the Parker Solar Probe. "We need to go so fast because we have to lose the influence of the Earth".
Over the course of seven years, Parker will make 24 loops around our star to study the physics of the corona, the place where much of the important activity that affects the Earth seems to originate.
Once on its way, the Parker probe will venture closer to our star than any other spacecraft.
The probe is created to plunge into the Sun's mysterious atmosphere, known as the corona, coming within 6.16 million kilometres of its surface during a seven-year mission.
The spacecraft eventually will run out of fuel and, no longer be able to keep its heat shield pointed toward the Sun, will burn and break apart - except perhaps for the rugged heat shield.
"In our very first flyby (of the sun), we get a little more than 15 million miles away from the sun's surface", Fox said.
"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. We've studied it from missions that are close in, even as close as the planet Mercury.
"Scientists have sought these answers for more than 60 years, but the investigation requires sending a probe right through the 2,500 degrees Fahrenheit heat of the corona". The trick was making the spacecraft small, compact and light enough to travel at incredible speeds, while surviving the sun's punishing environment and the extreme change in temperature when the spacecraft is out near Venus. On the probe Parker spent about $ 1.5 billion.
Bakayoko has been cast off by Maurizio Sarri this summer following a disappointing year since he joined Chelsea from Monaco. The 30-year-old Argentine marksman recently completed a sensational loan move to AC Milan from rivals Juventus.
As recently as June, China was the top foreign buyer of United States crude, importing a record 15 million barrels that month. Meanwhile, traders looked ahead to a report from The American Petroleum Institute on US crude inventory, due this evening.
If Liverpool want to continue to operate as one of Europe's elite teams, they'll have to get used to the weight of expectation. No team has successfully defended the English title since Manchester United in 2008-09.
It isn't clear if Google will release this in Malaysia so you'll probably need to turn to grey importers if you're interested. In additional photos, we can see that Google will apparently be changing the color of the power button this time around.
The problem? Many senior advisors were not aware of the photoshoot, and they ultimately banned her from sharing any of the images. But in an interview Sunday on NBC's "Meet the Press ", she said that she only heard the tape after her book had gone to press.
In the Netherlands, Ryanair filed for an urgent court order to try to prevent Dutch pilots from joining the industrial action . In July, around 300 flights were cancelled in similar strikes in Portugal, Spain and Belgium .
Fredericton's police chief, Leanne Fitch, says delivering news of fallen officers is the worst moment for any chief of police. The Liberal government unveiled proposals in March to tighten already tough gun control laws to address a spike in crimes.
After the oath of MNAs, the elections of the speaker and deputy speaker of the National Assembly will be held on August 15. Earlier, the maiden session started with the National Anthem, followed by recitation from the Holy Quran.
"I think there was one defensive mistake, and probably the linesman could have helped him and given a free-kick against Leicester.
Look up for the Perseid meteor shower this weekend
This year's Perseid meteor shower promises to be one of the best for stargazers as a new Moon bringing darker skies. The Perseid meteor shower peaks this weekend and viewing conditions should be spectacular in mid-Missouri.
Trump doubles steel and aluminum tariffs on Turkey
Trump announced the action Friday on Twitter . "Don't forget, if they have their dollars, we have our people, our God", he said. Erdogan has been putting pressure on the central bank not to raise interest rates in an attempt to help borrowers.
White House seeks to prevent Omarosa from releasing more tapes
Even Trump had begun wearying of Manigault Newman's omnipresence in meetings by the middle of his first year, those people said. It is the same amount that a few others who have departed the White House under inauspicious circumstances are receiving.
