中国月球车在月球背面行驶了463米

新华社北京6月28日电中国月球车“玉兔2号”在月球背面移动了463.26米,开始对这片处女地进行科学探索。


着陆器和月球车Chang 'e-4调查的19太阴日刚刚结束他们的工作,并切换到月球夜晚的休眠模式由于缺乏太阳能,月球勘探和中国国家航天局的太空计划中心周日说。


2018年12月8日发射的中国嫦娥四号探测器,于2019年1月3日在月球背面南极艾特肯盆地的冯卡门陨石坑首次软着陆。


由于潮汐锁定效应,月球的公转周期与自转周期相同,且同一面始终面向地球。一个月的一天相当于地球上的14天,一个月的夜晚也一样长。


在第19个月日,“玉兔二号”检查了月球车西南约3米处的一个小陨石坑,获得了一批新的科学探测数据。


Yutu-2月球车的设计寿命为3个月,但它的工作时间远远超过了设计寿命,成为在月球上工作时间最长的月球车。


月球车帮助科学家揭开了深埋在月球背面的秘密,丰富了人类对天体碰撞和火山活动的历史理解,并为月球的地质演化提供了新的线索。


嫦娥四号任务的科学任务包括进行低频无线电天文观测,测量地形和地貌,探测矿物成分和月球表面浅层结构,以及测量中子辐射和中性原子。


嫦娥四号任务体现了中国希望将太空探索的智慧与荷兰、德国、瑞典和沙特阿拉伯开发的四个有效载荷相结合。


中国计划在今年晚些时候发射首个火星探测器和嫦娥五号探测器,将月球样本带回地球。

 

BEIJING, June 28 (Xinhua) -- China's lunar rover Yutu-2, or Jade Rabbit-2, has moved 463.26 meters on the far side of the moon to conduct scientific exploration of the virgin territory.

Both the lander and the rover of the Chang'e-4 probe have just ended their work for the 19th lunar day, and switched to the dormant mode for the lunar night due to lack of solar power, the Lunar Exploration and Space Program Center of the China National Space Administration said Sunday.

China's Chang'e-4 probe, launched on Dec. 8, 2018, made its first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3, 2019.

As a result of the tidal locking effect, the moon's revolution cycle is the same as its rotation cycle, and the same side always faces the earth. A lunar day equals 14 days on Earth, and a lunar night is the same length.

During the 19th lunar day, Yutu-2 examined a small crater about three meters southwest of the rover and obtained a new batch of scientific detection data.

Yutu-2 has worked much longer than its three-month design life, becoming the longest-working lunar rover on the moon.

The rover has helped scientists unveil the secrets buried deep under the surface on the far side of the moon, enriching humanity's understanding of the history of celestial collision and volcanic activities and shedding new light on the geological evolution on the moon.

The scientific tasks of the Chang'e-4 mission include conducting low-frequency radio astronomical observations, surveying the terrain and landforms, detecting the mineral composition and shallow lunar surface structure and measuring neutron radiation and neutral atoms.

The Chang'e-4 mission embodies China's hope to combine wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia.

China plans to launch its first Mars probe and the Chang'e-5 probe to bring lunar samples back to Earth later this year.
