Entering a part of the Sun's atmosphere known as the corona for the first time, the probe will explore how energy moves through the atmosphere. About this сообщаетAFP, reports the Chronicle.info with reference to the UNN.
The probe won't actually land on the sun, but it will make history - getting closer than any other man-made object.
He said: "Wow, here we go!"
"This space weather has a direct influence, not always positive, on our technology in space, our spacecraft, it disrupts our communications, it creates a hazardous environment for astronauts and in the most extreme cases can actually affect our power grids here on the Earth", said Alex Young, associate director of NASA's Heliophysics Science Division.
But these solar outbursts are poorly understood.

Turkey crisis risks souring military ties with US
Some would like to see Turkey's central bank increase interest rates. "I'm not there yet and I don't think the market is there". BBVA is the most exposed, followed by UCG, ING, BNPP and HSBC , whose share price was down 0.8 per cent in afternoon trading.

I don't like to look too far ahead - we just need to do the talking on the pitch and make sure we perform well. The Guinean looked the part in pre-season and will be keen on making an instant impact in the Premier League.
Great knowledge about the solar wind and space storms will also help protect future space explorers when they go to the moon or Mars.
The shield should enable the spacecraft to survive its close shave with the center of our solar system, coming within 3.83 million miles (6.16 million kilometers) of the Sun's surface.
The probe is protected by an ultra-powerful heat shield that is 4.5 inches (11.43 centimeters) thick.
The probe will fly into a region where temperatures exceed a million degrees Fahrenheit (555,000 degrees Celsius) but the sun is expected to heat the shield to a relatively modest 2,500 degrees Fahrenheit (1,370 degrees Celsius). "Another question we hope to answer is: Why is the solar wind accelerating up to very high speeds in the corona?" Engineers tried to identifiy the problem, but the launch window - when a spacecraft can take off in the right direction due to the Earth's rotation - closed before they could make progress.
The device will measure the electromagnetic field of the Sun and determine the nature of the particles emitted by the star. "Some high-energy solar particles accelerate to almost half the speed of light, and we don't know why".
There is also a white light imager, taking pictures of what the spacecraft is about to "plow through", said Fox. When it nears the Sun, the probe will travel rapidly enough to go from NY to Tokyo in one minute - some 688,000kmh - making it the fastest human-made object.
