The Parker Solar Probe, the closest thing to the sun's history, will be launched at Cape Canaveral Air Force Base in Florida, United States, in early August.
IV heavy rocket launches in 16 weeks to enter the orbit of the sun and perform seven years of solar exploration missions.
On July 20, 10 days before launch, scientists at Parker's Solar Exploration Project Dr. Nicky Fox of the Johns Hopkins Applied Physics Laboratory and Dr. Alex Young of NASA's Goddard Space Flight Center have held a televised press conference at the NASA Kennedy Space Center to discuss the purpose of scientific exploration of the Parker probe.
Dr. Young said, "We have been studying the sun for decades" and "It's time for us to finally get there and move on." Video
NASA's solar probe Parker leaves Earth.
The sun is much more complicated than what we see with our eyes.
The atmosphere of the Sun constantly expels magnetized materials on the outside, envelops our solar system beyond Pluto, and during the solar system,
The Clean Energy Rings Explode the light and radiation of particles, which are transmitted through space, causing temporary confusion in the atmosphere of our Earth, and sometimes distorting radio and communication signals near the earth.
The influence of the sun on the Earth and the other planets of the solar system is known around the world as the time of the universe, and the key to understanding the origins of this meteorology depends on how much you understand the sun itself. The energy is still flowing in front of us. "
The solar wind is a huge amount of energy and particles that flow into the atmosphere, although it's not visible, but a beautiful dawn is wrapped around poles, because we do not yet understand the mechanism of the solar wind

Three riddle answers?
The Probe carries a series of instruments that can be used to study the sun from a distance or in the field.The data from these advanced equipment will help find answers to three fundamental questions about the sun.
The first is the mystery of the solar wind acceleration, the constant flow of the sun. We usually know some of the origin of the solar wind, but we still do not know where the solar wind is accelerating up to supersonic speed.
The data suggest that this change occurs in the crown, the outermost layer of the solar atmosphere. Parker's probe will pbad directly through the solar atmosphere, and scientists plan to reveal how this happens with remote and on-the-ground measurements.
The second plan is to unlock the secrets of the incredible high temperatures of Corona. The temperature of the visible surface of the sun is about 10,000 degrees Fahrenheit (5.538 degrees Celsius), but Corona is hundreds of times warmer and up to several million degrees Fahrenheit.
Since the sun's energy is generated in the center, the fact that the outer atmosphere, the crown, is so hot that the surface is not understood as being our intuition.
Finally, Parker's probes are also working to shed light on the mechanism behind the acceleration of the sun's energy particles, said Dr. Fox, "as if we were getting away from the campfire. and was getting a lot hotter. " These energy particles arrive at speeds faster than half the speed of light as soon as they are launched from the sun. These energy particles interfere with the electronic equipment of satellites, especially the electronics of satellites outside the Earth's magnetic field.

Four Advanced Exploration Equipments
To solve this question, Parker's probe will utilize four sets of equipment.
A led by Berkeley, California The FIELDS product line measures the electric field and the magnetic field around the probe. FIELDS will capture the waves and turbulence inside the solar wind with high resolution resolution, and study waves, shocks and magnetic field repetitions that are the explosive realignment of magnetic lines.
Whisper (WISPR) Parker is the abbreviation for Wide-Field Imager for Parker Solar Probe, the only imaging device on the probe.
Whisper is the mbad ejection (CME) of the sun-blowing crown, It captures images of other eruptions and helps to connect the phenomena that occur in gigantic corona structures with physical measurements detailed captured directly in the solar environment. Whisper is led by the Naval Research Institute in Washington, DC
SWEAP (abbreviation for SWEAP) is an abbreviation for the solar wind and corona plasma, C is a device for calculating helium ion and for measure acceleration, density and temperature Two complementary equipment is used. Sweep is led by the University of Cambridge, Cambridge, Berkeley and the Smithsonian Astronomical Observatory.
Finally, ISISIS is an acronym for Integrated Science Investigation of the Sun, which is a sign that symbolizes. The instrument measures particles from a wide range of sources of energy. Measuring electrons, protons and ions will help you understand the life cycle of particles, where they come from, how they accelerate and how they move from the sun through the atmosphere. space between the planets.
Solar exploration missions such as the Parker solar probe have long been the wishful thinking of a scientist for decades. With the recent development of technology, the advanced heat sink, solar panel, and error management system have been applied to achieve the dream. ” src=”http://www.sciencetimes.co.kr/wp-content/uploads/2018/07/176175_web.jpg” width=”480″ height=”364″/>

Technology Development Hot Solar Road Exploration It took 60 years. Since the beginning of the age of the universe, humanity has become curious about all the dimensions of the sun that have a powerful impact on the solar system.
In 1958, physicist Eugene Parker published a groundbreaking scientific article on solar wind theory. This solar exploration mission gave its name to NASA's space exploration mission and named it the first living person.
Parker's solar exploration is now a reality because the technology has grown considerably in recent decades. This drastic exploration of space is driven by three key technologies.
Dr. Andy Driesman, director of the parker solar exploration project at Johns Hopkins Applied Physics Laboratory, said, "The heat dissipation system makes this space mission possible. "
When a probe orbits around an orbit of about 6.4 million kilometers from the sun, the heat sink or shield will rise to about 1400 degrees Celsius," knows that it is about 29 degrees Celsius
The Parker Probe Thermal Protection System (TPS) is a type of carbon sandwich in which a carbon composite surrounds a 4.5-inch carbon foam. It has a thickness of 97% and is approximately 8 feet in diameter, but weighs only 160 pounds (72.6 kilograms) using lightweight materials.
Auto Error Fixed [19659002] Other Important Innovations Error Management System The solar cell cooling system is capable of producing energy without compromising the intense heat load of the sun, and the failure management system allows the spacecraft to protect the spacecraft even when the spacecraft can not communicate with the Earth for long periods. The management system protects the ship for extended periods, even when the probe can not communicate with the Earth, using data from the seven solar collectors placed around all the edges of the radiator shade.
The Delta IV heavy rocket is one of the most powerful rockets in the world, but the Parker probe is relatively small in size and
Because objects launched from Earth start to spin around from the Sun at a speed equal to the Earth's orbiting speed (18.5 miles per second), even if they are small, they require a lot of energy to get into orbit.

8 Mon Second Afternoon 5 ~ 7 City ( Korea ) ] The launch of the Parker Probe takes place two weeks before and after the beginning of August, between 4 pm and 6 pm in the eastern part of the United States (between 5 pm and 7 pm in Korea) . ” src=”http://www.sciencetimes.co.kr/wp-content/uploads/2018/07/176175_web.jpg” width=”480″ height=”364″/>
.
Dr. Yanping Guo of Johns Hopkins Applied Physics Laboratory, who designed the orbit of the probe, said: "The energy needed to reach the Sun is the Mars." C & # 39; is 55 times more than the energy needed to reach Earth and reach twice the amount needed to reach Pluto at the very end of the solar system. "" Earth and other solar planets are ideally aligned to send probes to the sun for in the summer. "
The probe will fly at 700 000 km / h and reach Venus in 8 weeks In Venus orbit, we use an auxiliary gravity device and leave the orbital energy network again for 8 weeks before entering the solar orbit.
The Parker Orbiter has crossed the orbit around the sun's surface at only 38 million miles (6.12 million kilometers) , and in 1976, the US and German exploration helicopter nd Helios 2,
Dr. Thomas Zurbuchen, chief scientist at NASA headquarters, said: "By studying the sun, we can see that more than the sun itself. "You can also learn more about all the other stars across galaxies, the universe and the origin of life."
