Will concern the Sun. Epoch-making mission of the probe Parker


NASA has sent the device which the first in the history will touch to our star to space. He should answer three main issues. The American space agency NASA has started in space the carrier rocket Delta IV Heavy with the probe Parker which has to fly by for the first time in the history through a crown of the Sun, having actually touched our star. Despite relative proximity scientists know about the Sun not so much, for example, why an external part of the atmosphere of a star one hundred times more hotly, than her surface. Корреспондент.net tells details. We will for the first time touch the Sun on August 12 the epoch-making space mission of NASA for the detailed studying of a crown of the Sun first in the history started. The mission is also unprecedented in details of her realization. So the probe Parker which has received a name in honor of the astrophysicist Eugene Parker described the solar wind causing a polar light and magnetic storms on Earth for the first time in the history literally will dive into an upper atmosphere of the Sun. Scientists have understood the tornado nature in the Sun This device became the first in the history of NASA, called in honor of the person. To Parker now 91 years, in 1958 he has written work in which I have predicted existence of solar wind (the stream of charged particles which is constantly let out by the Sun). Then his theory was perceived by many in bayonets while existence of wind on has been proved experimentally in 1962 during Mariner-2 mission to Venus. With the naked eye from Earth we can observe only a small part of sunlight therefore the Sun seems to us very quiet and stable disk. However our star is continuously broken off on a part by powerful explosions therefore streams of charged particles and electromagnetic radiation - so-called solar wind - scatter on billions of kilometers around. The device will approach a star on distance of six million kilometers - it is the one tenth part of distance from the Sun to Mercury, the next to him planets. Meanwhile the German-American probe Helios-2 which in 1976 has flown by in 43,4 million kilometers from the Sun was the closest terrestrial guest. The average distance of Earth from the Sun makes 149,6 million kilometers. "Touch the Sun", - the motto of a mission which should fly there where for all history of astronautics any device didn't fly. Also Parker will become the fastest of ever the devices started by the person in space. His speed will be 192 kilometers per second. The probe will measure electric and magnetic fields in the atmosphere of the Sun, to study structure of solar wind and to photograph a crown - external area of our star which by millions of degrees hot his surfaces. Parker is designed to answer such questions: As well as why particles of solar wind accelerate to transsonic speeds in a crown of the Sun? What mechanism of heating of particles in a crown? How do separate particles which manage to reach oklosvetovy speeds accelerate? "So far we won't be able to explain what occurs near the Sun, we won't be able to predict space пог
