In 2024 BepiColombo will visit Mercury.

In ancient times, Thus the Babylonians called the goddess Mercury, Nabu, who was full of intelligence. And the god of writing. For the Romans, called Mercury, Mercury, the Greek, attributed the same god Hermes, the god of communication and interpretation. This is the source of the word hermeneutic, which refers to the science of interpretation.

As a journalist, Hermes is famous. Homer wrote this talisman in the Odyssey literature that he had wings with wings.

The speed of the storm. In antiquity, nobody knew it. Mercury is the fastest orbit of the five known human planets (ie Wednesday, Friday, Tuesday, Thursday and Saturday) Thus, the name Hermes is the proper name of Mercury

The Romans praised the gods. Mercury is the commercial goddess. The guardian He acts secretly. Not visible to anyone In the form of an invisible corpse. He gave Perseus the name of a medallion to use to kill Kali Medusa in Hell, as well as the giant Angus who has 100 eyes.

Most of them now know Mercury. But never seen Because Mercury often appears above the horizon at dusk. And the sunrise For reasons that are not more than 28 degrees from the sun, it is closest to the sun in most planets, so when we see Mercury near the horizon. Because the light of the star has to travel long through the atmosphere of the Earth over long distances.

In 1639 (under the reign of King Prasat Thong), Giovanni Battista Zupi was the first Roman priest to see the waning moon. Mercury C is because it is orbiting the sun. The surface of Mercury is unevenly lit by the sun, such as the time between the Earth and the sun. The side facing the world is dark. The surface of the star is brilliant. Then he becomes dark again. Shortly after, Johann Hieronymus Schroter reported seeing a darker area compared to the darkness of Mercury

In 1889, Giovanni V. Schiaparelli, astronomer of Milan in Italy, claimed that on the planet Mars has a human. And there are many channels. Posted Mercury revolves around him for 88 days and takes as long to orbit the sun, so Mercury turns his face towards the sun just as the Moon turns its head towards the Earth.

In the middle of the 19th century, at age 19, many physicists began to question the perfection of the gravitational law that Newton found: Urban Le Verrier found that the orbit of Mercury Was never the same as the axis of the circle. The orbits will be slightly deflected by about 1 degree every 625 years, which can not be explained by Newton's laws of gravity. The results of the measurements were then confirmed by Simon Newcomb

. Physicists have suggested that there are many possible causes, like another mysterious planet called Vulcan that revolves around the orbit of Mercury, some people think that our sun is not spherical because everyone thinks it's right. Central Some people have suggested this. Gravitational law does not inverse the square of distances. But it's a distance of 2 + E when E is a decimal

But these suggestions have not been proven true or even true. Because it does not matter which telescope to use. No astronomer sees the planet Vulcan to measure the size of the sun. Sunbeam in different directions The same value everywhere. Newton's gravitational law does not need to be adjusted. Finally, Albert Einstein allowed all physicists to agree that Newton's gravitational law is not just perfect. By proposing general relativity. In the May 20 issue of Physical Review Letters, May 8, Clifford Will of the University of Florida at Gainesville United States calculated the effect that it is based on the use of relativity general to study the orbit of Mercury in more detail. The gravity of Jupiter is determined by Mercury. The only difference is the current technology (with the exception of the sun itself), which has increased the axis of the orbit by 1 degree every 2,000 million years. It can not be measured, but the European Space Agency's BepiColombo spacecraft will send it to Mercury in 2024, another six years to measure it.

Important for Mercury. Alva Edison and Seth B. Nicholson used a telescope at Mount Wilson to analyze the light reflected by Mercury and found that the surface of Mercury on the Sun was 410 degrees Celsius. The temperature is -130 to -185 degrees C. The temperature is very high and very low. On Mercury is not likely to have a life.

In 1965, Gordon H. Pettengell and Richard B. Dyce sent radio waves from the Arecibo radio telescope to the surface of Mercury. Measure the wavelength of the reflected wave. In comparison, this time with 88 days, Mercury turns into orbit around the sun, the ratio of 58.6 / 88 is about two thirds that of the sun.

On March 29, 1974, NASA sent the Mariner 10 to explore Mercury at a distance of 700 kilometers above the star. The photos of the vehicle show it. The skin has many craters. As the moon's skin The largest meteorite, the Caloris Basin, has a diameter of 1,300 kilometers, because of its high edge. Thus, half of the holes will never get sunlight. Astronomers have assumed that.

39 years later, on March 10, 2015, NASA sent the MESSENGER (MErcury Surface Space Environment GEochemistry and Ranging) to Mercury. A camera, a spectrometer, which analyzes the composition of gas and rock on the star, passed near Mercury at a distance of 200 kilometers and 15,191 kilometers, and MESSENGER reported. The mercury has a diameter of 4,878 km (the Earth's diameter is 12,756 km, 3,476 km and 6,787 km.) Since 75% of the star's mass is steel, the l? Gravitational acceleration of Mercury is sufficient. More With the acceleration due to gravity on Mars. The Mercury is smaller.

After putting 4,204 rounds of mercury into orbit over 4 years, 1 month, 12 days, the spacecraft took a detailed photo of Mercury. Explore the atmosphere on the surface. The composition of the soil has been analyzed. At the collapse, NASA forced MESSENGER to dive to Mercury to destroy himself at a speed of 14,100 km / h.

In 2017, the European Space Agency and the Japan Aerospace Exploration Agency Japan plans to send BepiColumbo visit Mercury in 2024, where BepiColumbo will conduct several experiments at MESSENGER.

(1) Mercury Planetary Orbiter (DFO) to study the surface chemistry of stars. And explore the rocky conditions on the planet to get a better geological knowledge of the stars. And more.

(2) Mercury Magnetospheric Orbiter (MMO) acts to analyze the magnetic field of the star.

ESA determined that when BepiColombo approached Mercury The two planets will separate: DFO will approach Mercury at a distance of 480 km and 1500 km, the MMO will have an orbit greater than 590 km and 11,640 km

. Mercury C is interesting because MESSENGER found that the magnetic field of the southern polar axis of Mercury is about 3 times less intense than the North Pole and that the center of the magnetic field is not at center of the star. It is about 480 km north of the center. The axis of the magnetic field is 4.5 degrees with the spindle. (As in the case of the Earth, the magnetic axis is at an angle of 11 degrees with the pin)

Thus, the magnetic field of Mercury is different from that of the Earth. This is another puzzle where DFO and DFO must find the answer.

Another strange thing about Mercury is instead of having large amounts of iron on the surface of the star. Because of other elements. Lighter than sublimation lost in space. Receiving a lot of heat from the sun all the time. Mercury's surface contains only 2% iron, with magnesium, potassium, chlorine, and sulfur in a relatively small amount, but almost without oxygen. The abundance of elements on Mercury is similar to that of Mars and from BepiColombo. Planned to use the spectrometer to explain this cause by measuring infrared radiation to various elements released at the same time. In the past, 56 years ago, space technology introduced satellites. Telstar®, the world's first commercial communications satellite, revolves around the Earth at distances of 954 to 5,635 km above the Earth. To communicate and send. The main function of Mercury, but TelstarⅠ works faster. Because the signal used to receive and travel at the speed of light. It's a new era of communication. And if the gods knew Telstar, they would no longer use Mercury to communicate.
