Chang' e 5, a little knowledge of the moon, completed its first calibration!

exploring the moon has always been a scientific and technological project of great interest to all countries. Since the 21st century, China Aerospace has undoubtedly been a pioneer in leading the cause of human exploration of the moon. In the sixteen years since the official launch of the Chang 'e lunar exploration project in 24, China Aerospace Lunar Probe has launched the largest number, the highest success rate, the greatest achievements and the greatest pioneering and innovative efforts.

Chang' e-1, Chang' e-2, Chang' e-3, Chang' e-5 T1 and Chang' e-4 have achieved five victories in five missions to the moon, and have continuously broken through and mastered a series of core engineering technologies, such as flying around the moon, soft landing on the lunar surface, lunar patrol and returning to the lunar orbit.

The Long March-5 remote-5 carrier rocket, which is about to carry out the sampling and returning mission of Chang 'e-5 on the 24th of this month from 4: to 7: a.m., is in station 11 of Wenchang launch site, Hainan, and is ready to bow, according to the arrangement of the mission launch window.

The experimental journey of the Chang 'e V Pathfinder has set sail. Yesterday at 2 o'clock in the morning, a small member of the Chang 'e family, the third phase of China's self-developed lunar exploration project, re-entered and returned to the flight tester, which was launched by the Long March III C carrier rocket in xichang satellite launch center and accurately entered the earth-moon transfer orbit. As of 16: yesterday, the Chang 'e V flight tester, known as "Little Chang 'e", had been flying in space for 14 hours, with a height of about 13, kilometers from the ground. The successful launch of the spacecraft marks the perfect first step of the reentry flight test for the first time in China's lunar exploration project.

At 16: 29 yesterday, under the control of beijing aerospace control center's scientific and technical personnel, the re-entry flight tester successfully implemented the first mid-course correction of the Earth-Moon transfer orbit.

The moon is what we often say. In ancient times, China, also known as Taiyin, Xuantu, Chanjuan and Yupan, is a satellite of the earth and the fifth largest satellite in the solar system. The diameter of the moon is about a quarter of that of the earth, and its mass is about one-eighty-first of that of the earth. Its surface is covered with craters formed by the impact of small celestial bodies. The average distance between the moon and the earth is about 384,4 kilometers, which is about 3 times the diameter of the earth.
