Go through thousands of mountains and rivers, just to knock on the neighbor\’s door -why Mercury is so close but so difficult to go

In the vast universe, the solar system is a mysterious celestial system. In this system, many neighbors on the earth have their own unique characteristics and significance. In the exploration of these neighbors, Mercury\’s exploration journey is particularly difficult and challenging.

Mercury, as the planet closest to the sun, its surface temperature is as high as 430 degrees Celsius, which brings great difficulties to the detector\’s approach . Not only that, the huge grain of the sun also makes the detector flying to Mercury must face extremely high speeds, and when it is close to Mercury, it takes a lot of fuel to decelerate and enter the track.

scientists have found that Successful on Mercury trackThe quality of the fuel must account for more than 85%of the total quality of the detector, which undoubtedly puts huge pressure on the design and cost of the detector, because the remaining 15%also accommodate various instruments and equipment . In addition, Mercury itself runs around the sun at a speed of 170,000 kilometers per hour, which means that the detector must surround Mercury, and it must also reach similar high speeds, which further increases the complexity of the task.

In the face of these difficulties, human exploration of Saturday is not smooth. As early as 1973, humans visited Jupiter for the first time, and did not visit Mercury until 1974. Although Mercury is closer to the earth .

Mercury seems to be forgotten in the corner and no one asked. Until 1985, someone proposed a \”curve to save the country\” solution to solve the exploration of Mercury exploration of Mercury.

Only in 1998 were seriously considered . In 2004, the \”Merchant\” Mercury detection task was finally launched. -Darkmode-color: #000000; \”> It has been flying in the universe for 6 years and 7 months, and used Planet\’s gravitational slingshot effect to accelerate and change tracks, thereby gradually approaching Mercury > \”>> .

In this long journey, it turned 15 laps around the sun, passing the earth once, twice Venus, and Mercury three times. span> In the process, the \”messenger\” did not only rely on the gravitational slingshot effect, but also cleverly borrowed it. Mercury atmosphere and solar wind to slow down.

Design this complex orbit is Chen Wanyan, an engineer in the jet promotion laboratory. Ordinary women . Design the \”Merchant\” flight track . #A3A3A3; \”> This track is full of twists and turns, and you need to grasp every detail accurately. Chen Wanyan fully considers various factors, such as the position of the planet, the strength of the gravitational field, and the performance of the detector, etc., ensuring that the\” Merchant \”can fly smoothly according to the scheduled track </strong.\"

2011,\” Credit \”finally finally finally Arrive in Mercury . The original plan to work for one year and took 1,000 high -definition photos \”Music\” exceeded the task.

More than 200,000 photos, these photos provide us with complete images from Mercury\’s appearance to kernel, from geological structure to magnetic field characteristics. By analyzing these photos and data, our understanding of Mercury has greatly improved .

\”Merchant\” also conducted in-depth research on Saturday\’s chemical composition and internal structure, which revealed the formation and evolution of Mercury for us. The process has taken an important step for the mystery of human exploration of the solar system. In the end, the success of the \”Merchant\” is undoubtedly the crystallization of human wisdom and courage . Basic. The exploration spirit of the number will inspire us to continue to move forward to unveil the mystery of more universe.
