China Lands Chang'e-5 Spacecraft on Moon to Gather Lunar Rocks and Soil

The New York Times

China has landed a robotic spacecraft on the moon, Xinhua, the official statenews agency reported on Tuesday. The probe will spend two days gathering rocks and dirt from the lunar surface, with the goal of returning the first cache of moon samples to Earth since 1976.

The spacecraft, Chang’e-5, was the third successful uncrewed moon landing by China since 2013, when Chang’e-3 and its Yutu rover became China’s first visitor to make a lunar soft landing. In 2019, Chang’e-4 landed on the moon’s far side, the first spacecraft from Earth to ever do that. At least three more Chang’e moon landers are planned for the coming decade, ahead of China’s aspiration of building a moon base for astronauts in the 2030s.

If the operations on the moon and the return to Earth are successful, China will be only the third nation to bring lunar samples here. NASA astronauts accomplished that feat during the Apollo moon landings, as did the Soviet Union’s Luna robotic landers, ending with Luna 24 in 1976. Those samples made major contributions to the understanding of the solar system’s evolution, and planetary scientists have eagerly waited for additional samples.

After the spacecraft entered orbit around the moon, Chang’e-5 was split into two: the lander now on the surface and an orbiter that awaits its return. The spacecraft braked and successfully entered an elliptical orbit on Saturday, and braked again on Sunday to enter a nearly circular orbit, according to CCTV, the state television network. Additional maneuvers on Monday and Tuesday prepared the landing spacecraft for its descent to the surface.

The lander touched down at Mons Rümker, a volcanic plain on the moon’s near side that is estimated to be around 1.2 billion years old. That is considerably younger than the places explored by Apollo and Luna, which were all more than three billion years old.

The lander will need to accomplish its drilling and scooping tasks within a single lunar day, which lasts 14 Earth days. It is not designed to survive the frigid and dark lunar night.

The Chang’e-5 lander includes a small rocket, and before the sun sets, it will blast off with the rock and soil samples. This rocket will rendezvous and dock with the orbiting spacecraft for the journey back to Earth. The samples will be transferred to the orbiter for the journey back to Earth.

The sample is scheduled to land in China’s Inner Mongolia region in the middle of December.

The young age of the samples could prove valuable to scientists on Earth, who can use them to better calibrate techniques for estimating the ages of geological surfaces on planets, moons and asteroids throughout the solar system.

The specimens may also help scientists test hypotheses about what caused the volcanism evident in the region of the moon where Chang’e-5 landed.

The New York Times

China has landed a robotic spacecraft on the moon, Xinhua, the official statenews agency reported on Tuesday. The probe will spend two days gathering rocks and dirt from the lunar surface, with the goal of returning the first cache of moon samples to Earth since 1976.

中国官方媒体新华社周二报道，中国的一艘机器人航天器已经在月球着陆。本次探测将用两天时间采集月球表面的岩石和土壤，从而带回自1976年以来的首批月球样本。

在恏渏 亾類哋夲能文中提到了probe作名词有“探索；探查；查究；调查”的意思，英文解释为“an attempt to discover information by asking a lot of questions”，如：an FBI probe into corruption 联邦调查局对腐败的调查；也可以指“（医生或科学家用的）探针”，英文解释为“a long thin metal instrument that doctors and scientists use to examine parts of the body”。

此处probe解释为“探测器”，英文解释为：a device that is put inside something to test or record information. 如：a space probe 航天探测器/太空探测器。

🎬电影《像素大战》（Pixels）中的台词提到：That videotape will be placed in a space probe 录影带将放在太空探测器中。

此外，也可以作动词：

1）表示“调查；探寻”，英文解释为“If you probe into something, you ask questions or try to discover facts about it.”举个🌰：

The more they probed into his background, the more inflamed their suspicions would become.

他们越深入调查他的背景，对他的怀疑就会越强烈。

2）表示“用探针探查”，英文解释为“If a doctor or dentist probes, he or she uses a long instrument to examine part of a patient's body.”举个🌰：

He probed around the sensitive area.

他在敏感部位周围做了探查。

1）表示“聚集；集合”，英文解释为“When people or animals gather, they come together in a group.”举个🌰：

A crowd had gathered to hear her speak.

一群人围拢过来听她演讲。

2）表示“收集，搜集；聚集，集拢”，英文解释为“to collect several things, often from different places or people”举个🌰：

The spacecraft, Chang'e-5, was the third successful uncrewed moon landing by China since 2013, when Chang'e-3 and its Yutu rover became China's first visitor to make a lunar soft landing. In 2019, Chang'e-4 landed on the moon's far side, the first spacecraft from Earth to ever do that. At least three more Chang'e moon landers are planned for the coming decade, ahead of China's aspiration of building a moon base for astronauts in the 2030s.

本次的嫦娥五号航天器成功完成了中国自2013年以来的第三次无人月球着陆，第一次的嫦娥三号和玉兔月球车是中国首次在月球上软着陆。2019年，嫦娥四号在月球远端着陆，是来自地球的航天器首次做到这一点。在未来十年里，嫦娥月球着陆器按计划还会有至少三次任务，而后中国的设想是在2030年代建造一座供宇航员使用的月球基地。

rover常见意思是“ 流浪者；漫游者”（a person who roves; wanderer），此处rover的英文解释为“a vehicle for exploring the surface of an extraterrestrial body (as the moon or Mars)”，即指部署在火星/月球上的探测器，即火星车/月球车，此前在「嗯，用不了多久...」一文中就提到美国的火星探测车（亦称为机遇号/机会号/火星探测漫游者-B，MER-B）因火星尘暴与地球“失联”3个多月时就这么表达：An American rover called Opportunity stopped working six months ago in a dust storm, but may revive if wind blows the dust off its solar panels.

📍此外，我们常听说的汽车品牌“路虎”的英文就是“Land Rover”。

Land Rover is a luxury car brand that specialises in four-wheel-drive vehicles, owned by British multinational car manufacturer Jaguar Land Rover, which has been owned by India's Tata Motors since 2008.（Wikipedia）

表示“着陆器，着陆舱，登陆载具”，英文解释为“a spacecraft designed to land on the surface of a planet or moon”。

If the operations on the moon and the return to Earth are successful, China will be only the third nation to bring lunar samples here. NASA astronauts accomplished that feat during the Apollo moon landings, as did the Soviet Union's Luna robotic landers, ending with Luna 24 in 1976. Those samples made major contributions to the understanding of the solar system's evolution, and planetary scientists have eagerly waited for additional samples.

如果成功完成本次月球任务并返回地球，中国将成为第三个将月球样本带回的国家。美国国家航空航天局(NASA)宇航员通过阿波罗登月行动完成了这一壮举，此外还有苏联的机器人月球着陆器，最后一次是1976年的月球24号。那些样本对理解太阳系演化有着极大的帮助，行星科学家在热切盼望得到更多的样本。

feat表示“功绩；技艺；武艺；功绩；英勇事迹”，英文解释为“If you refer to an action, or the result of an action, as a feat, you admire it because it is an impressive and difficult achievement.”如：to perform/attempt/achieve astonishing feats 表演惊人的技艺；争取/取得惊人的功绩，举个🌰：

一周内就把这项任务完成了，真了不起。

🎬电影《惊天魔盗团2》（Now You See Me 2）中的台词提到：by performing what he calls an impossible feat. 在这里上演他所谓不可能的奇迹。

After the spacecraft entered orbit around the moon, Chang'e-5 was split into two: the lander now on the surface and an orbiter that awaits its return. The spacecraft braked and successfully entered an elliptical orbit on Saturday, and braked again on Sunday to enter a nearly circular orbit, according to CCTV, the state television network. Additional maneuvers on Monday and Tuesday prepared the landing spacecraft for its descent to the surface.

进入环月轨道后，嫦娥五号会分解成两部分：着陆器已经在月球表面，还有一个轨道飞行器在等待它返回。据国家电视台CCTV的报道，航天器在制动后于周六成功进入椭圆形的轨道，周日再次制动，进入一个接近圆形的轨道。周一和周二的其他动作为着陆器下降到地面作了准备。
