What is Moon Car? Lunar rover explained

A lunar rover is a specialized vehicle that can travel on the lunar surface and complete complex tasks such as lunar exploration, investigation, collection and analysis of samples. In the laboratory, the scientific name of this important role is the "lunar rover", in order to make the lunar rover can drive smoothly on the lunar surface, the United States, the former Soviet Union has launched a series of satellite exploration, and repeated scientific experiments on the lunar environment, Tankikong has laid a reliable foundation for the success of carrying the lunar rover on the probe. <

A lunar rover is a specialized vehicle capable of driving the blind lunar surface and completing complex tasks such as lunar exploration, investigation, collection and analysis of samples. In order to make the lunar rover run smoothly on the lunar surface, the United States and the former Soviet Union have launched a series of satellite explorations and conducted repeated scientific experiments on the lunar environment, laying a reliable foundation for the success of carrying the lunar rover on the probe. Scientists have analyzed and studied the valuable data brought back from the field expedition to the lunar surface of the lunar rover, which has greatly deepened mankind's understanding of the moon.

Interpretation of the lunar rover: a special vehicle that travels on the surface of the moon and investigates the moon and collects samples for analysis. There are two kinds: (1) unmanned lunar rover.

Solar cells and accumulators are combined to supply electricity. According to the remote control command on the earth, it enters the Bird Fighting Group and automatically collects lunar rocks and lunar soil, detects and photographs the lunar surface conditions, and then analyzes them through the instruments in its instrument cabin, and then sends them back to the earth by communication transmission equipment. (2) Manned lunar rover.

Powered by a battery. The lunar module of the manned spacecraft is sent to the surface of the moon for the use of lunar astronauts during their activities on the lunar surface.

Word Breakdown Explanation of the moon The moon is the largest natural guardian star (also known as the "moon", "moon"): moonlight (the moon reflects the sun's light). Eclipse.

Timing unit: January. Month.

Time goes by (time goes by without stopping). Appears monthly, monthly: monthly.

Monthly salary. Shaped like the moon, round: moon cake.

Jade Rabbit. Yutu is China's first lunar rover, and together with the lander, it forms the Chang'e-3 probe. With a design mass of 140 kilograms and solar energy, the Yutu lunar rover can withstand extreme environments such as vacuum on the lunar surface, strong radiation, and extreme temperatures of 180 degrees Celsius to 150 degrees Celsius above zero in the impulse state.

The lunar rover has the ability to climb 20 degrees and cross obstacles by 20 centimeters, and is equipped with scientific detection instruments such as panoramic camera, infrared imaging spectrometer, lunar radar, and particle excitation X-ray spectrometer.

Details: At 1:30 a.m. on December 2, 2013, China successfully launched the Chang'e-3 probe into orbit at the Xichang Satellite Launch Center. At 4:35 a.m. on December 15, 2013, the Chang'e-3 lander separated from the rover, and the Yutu rover successfully sailed to the surface of the moon.

At 23:45 on December 15, 2013, the Yutu revolved around Changqiaozhi'e-3 to take pictures and sent it back.

In the early morning of January 25, 2014, the Chang'e-3 lunar rover went dormant on a moonlit night for the second time. However, before hibernation, due to the influence of the complex lunar environment, the mechanism control of the lunar rover was abnormal. On February 10, 2014, the first Yutu woke up failed.

On the night of February 12, 2014, the Yutu lunar rover was fully awakened and its condition tended to improve, but the problematic "mechanism" still needs to be further restored.

The lunar rover is called Yutu-2.

Yutu-2, the Chang'e-4 lunar rover, completed its separation from the Chang'e-4 lander at 22:22 on January 3, 2019, and arrived on the far side of the moon. The landing on the far side of the moon for the first time has become another milestone in the development of China's aerospace industry.

At 11:53 on May 16, 2020, the "Yutu-2" lunar rover ended its cold and long moonlit night dormancy, woke up spontaneously by the light, and ushered in the 18th month of daytime work period.

On August 13, 2020, the Chang'e-4 lander and the Yutu-2 lunar rover ended their moonlit night sleep at 14:54 on August 13 and 20:34 on August 12, respectively. The two instruments are in normal working condition, and the energy balance of the tape measure continues the exploration journey on the far side of the moon.

On January 3, 2021, the Chang'e-4 lander and the Yutu-2 lunar rover have been working on the lunar surface for 731 days.

On March 8, 2021, the Chang'e-4 lander and the Yutu-2 lunar rover completed the wake-up setting, ushering in the 28th lunar day. As of March 8, 2021, Chang'e-4 has been working on the far side of the Moon for 795 Earth days.

As of April 6, 2021, Chang'e-4 has spent 825 Earth days on the far side of the moon, and on that day the Chang'e-4 lander and the Yutu-2 lunar rover entered their 29th lunar day.

Naming meaning:

The name of the lunar rover of the Chang'e-4 mission reflects the cultural origin of the Chang'e project as the destiny of China's lunar exploration program, and is in the same vein as the Chang'e-3 "Yutu" and the Chang'e-4 relay satellite "Queqiao", which is not only easy to accept by the masses, but also easy to remember and disseminate.

At the same time, the image of Yutu's kindness, purity and agility is both similar to the structure and mission of the lunar rover, reflecting China's position on the peaceful use of space.

On January 3, 2019, the lunar rover of the Chang'e-4 mission was finally named "Yutu-2".
