China says spacecraft successfully lands on moon for historic sample collection.

A Chinese robot probe landed on the moon Tuesday, touching down on a broad plain known as the Ocean of Storms in a bold attempt to scoop up rocks and soil and return them to Earth for laboratory analysis, the first such lunar sample collection in nearly 45 years.

At 23:11 on December 1 (10:11 a.m. EST), the Change 5 probe successfully landed on the pre-selected landing area near the front of the moon at 51.8 degrees west longitude and 43.1 degrees north latitude," the Chinese space authorities reported in translated remarks.

After touchdown, the agency said, the lander deployed its solar wings and a directional antenna and began preparing for sample collection, a procedure expected to take about two days.

Congratulations to China on the successful landing of Change 5," tweeted Thomas Zurbuchen, NASAs science director. "This is no easy task. When the samples collected on the moon are returned to Earth, we hope everyone will benefit from being able to study this precious cargo."

If the sample collection and return to Earth are successful, China will become only the third nation, after the United States and the former Soviet Union, to bring moon rocks back to Earth, and the first since Russias robotic Luna-24 mission in 1976.

Named after the mythical Chinese goddess of the moon, the 8,335-pound Change 5 spacecraft features four major components: a lunar orbiter and sample return craft; the lander carrying science instruments and sample collection gear; and a small ascent vehicle mounted atop the lander to carry the collected surface samples back up to orbit for return to Earth.

Launched November 23 atop a powerful Long March rocket, the Change 5 spacecraft braked into orbit around the moon on Saturday and released the lander the next day. On Tuesday, the lander fired its main engine at 9:57 a.m. EST to drop out of orbit for the long-awaited descent to the surface.

During the final stages of the descent, the probes flight computer carried out automatic obstacle avoidance procedures before dropping vertically to a gentle touchdown at 10:11 a.m. and beaming back a camera image of the ground below the spacecraft.

The flight plan calls for a short two-day stay on the surface. The lander is expected to photograph its surroundings in detail with high-definition cameras and use a spectrometer and ground-penetrating radar to assess the area near the spacecraft.

A robot arm equipped with a percussive drill and scoop will excavate and pick up loose rock and soil. The arm then will transfer the collected samples up to the ascent vehicle, which is expected to blast off Thursday, using the lower half of the lander as a launch pad.

After a climb back to lunar orbit, the spacecraft will rendezvous and dock with the Change  5 orbiter Saturday and transfer the samples to the return craft for the trip back to Earth. Landing in Inner Mongolia is expected around December 16.

China is executing an incremental approach to its moon program, launching a series of increasingly complex robotic spacecraft to develop and test the propulsion, guidance, navigation and landing systems needed for long-term exploration.

The Change 1 and  2 missions successfully reached lunar orbit in 2007 and 2010 respectively, followed by the Change 3 lunar lander in 2013 and Change 4, which landed on the far side of the moon in 2019. Change 5 is the first of two planned sample return missions and Chinas most ambitious moon mission to date.

CHINA MOON BASE.美國憂慮中國的月球基地,

將佈署終極軍事科技武器.

狂賀中國太空探險工程大突破,嫦娥5號太空船成功登陸月球,採集礦石及土壤返回地球,中國太空探險工程大突破,,中國歷經20年研究有成,創造出可以循環利用的太空船,進行登陸月球進行各式各樣的科學研究,但是美國指責中國進行太空密秘任務.

中國北京時間12月1日23時，嫦娥五號探測器成功著陸於預先選定的月球表面區域，舉世矚目的“五妹”成功“打卡”，標誌著中國科學探測器第三次成功軟著陸於月球表面。中國航天科技集團五院西安分院.,20201202日透露，在這次技術含量極高的科學“打卡”中，西安分院為嫦娥五號探測器研製的微波測距測速敏感器、測控天線、數傳子系統是“五妹”輕盈落月的關鍵。

在嫦娥五號探測器抵達月球軌道後，著陸器攜帶著上升器著陸於月球表面。西安分院為嫦娥五號探測器研製的微波測距測速敏感器相當於在著陸器上安裝了一部“泊車雷達”。嫦娥5號微波測距測速敏感器可以探測落月的速度和距離的信息之外，西安分院為嫦娥五號研製的測控天線和數傳子系統也是成功實現落月的關鍵。安裝在上升器上的測控天線相當於是“五妹”隨身攜帶的“手機”，與月球之間的測控通信主要依靠這部“手機”完成。落月過程中的測控通信的信號都是通過測控天線來發送和接收的。而數傳子系統則在落月的過程中，將著陸器在著陸過程中拍攝的照片實時地傳回地面，為地面的決策提供依據。

在微波測距測速敏感器的研製任務中，西安分院採用了多晶片集裝技術的第四代接收機，加上在設計過程中採用了多晶片的整合封裝和採用新材料，能夠將微波測距測速敏感器的重量減少到14公斤，相比於嫦娥三號減重近10公斤。

China space engineering so great.China will construction military base in the MOON.?

美國太空總署NASA.發言聲稱這樣一來中國,繼美國及蘇聯在45年以後,再度成功派遣無人太空船登陸月球,採取礦石,做科學研究,但是美國的國防部及太空軍總部表示,中國極為可能藉由太空探險工程,進行在月球佈署軍事基地的可能性,我們美國必須加速研究,重新登陸月球,建立永久性的太空基地.

國際戰略專家分析認為20世紀美國與蘇聯的太空爭霸戰中,最後由美國阿波羅太空船登陸月球成功,插上美國的國旗,以及採取月球的礦石返回地球,分別贈予許多多國家,收藏留念,太空爭霸戰而告一段落.

如今21世紀中國強勢崛起,在太空科學領域及太空工程項目方面,有極大的成就,中國不僅發射成功,環繞月球的載人天宮太空船,進行對於太空探險以及對於登陸月球的種種科學實驗,又此番以無人太空船登陸月球成功,比較前次嫦娥3號月球探險太空船登陸月球,又是一項突破太空工程的創舉.根據中國國家太空科學院的計劃,中國計劃於2025年將人類,運抵月球建設月球太空站CHINA MOON BASE. 屆時經電視台轉播中國登陸月球的太空探險旅程.

但是美國的情報顯示出,中國除了加速研究創新太空工程探險活動,指出中國在月球進行密秘任務.他們要在月球搜尋稀有的礦石,作為日後中國的能源替代品,如果中國真的收蒐集到,這樣一來中國在日後的300年,都不愁因為地球的石油及天然氣的耗盡,而影響到中國的生存及發展.

2020年中國嫦娥5號登陸月球,除了科學實驗外,最重要的是密秘搜尋稀有礦石3He.氦-3.重要的資源,由於中國改革開放以來,工業,商業突飛猛進,甚至於軍事科技的發展也躍居於世界第三名,僅次於美國及俄羅斯,對於石油及天然氣已經追逐美國成為消費者第一名,如此一來中國在能源需求量方面是需款孔急,實在是要尋求新的能源替代品,好銜接未來工業,商業甚至於軍事上的需求,傳聞中國已經實驗成功3-He.轉換成商業利用,不僅無任何環境污染的產生,而且效益頗佳,可以使用1000年之久?

價格成本低於石油與天然氣,最重要的是將可以運用於導向飛彈軍事武器,效力與威力將形成無法抵抗的高科技武器,亦可以佈署於月球基地,對於地球任何地區進行打擊,這樣一來為什麼美國得知中國的太空探險工程中,列入極為機密的任務,就是開發掘起月球蘊藏量豐富的稀有礦石3He.氦-3,運回地球提煉,甚至於在月球建設工廠就地解決?

上一世紀美國與蘇聯太空爭霸戰中都有取得月球的礦石及土壤,進行科學分析及研究稀有礦石3He.氦-3.,發現月球蘊藏量極為豐富,在地政幾乎是沒有的,因為開發建設提煉稀有礦石3He.氦-3.成本極高,不符合當時的投資成本及商業運轉效益,因為上一世紀的人類,享受到石油及天然氣的經濟成長,尤其是美國及西方國家尤為售惠如今環境保護高漲石油及天然氣愈來愈少僅供人類未來100年內就消耗殆盡因此美國及西方國家俄羅斯,日本等國家,積極密秘的蒐集與收搜尋鄋稀有礦石3He.

氦-3.不惜任何代價及不擇手段,蒐集情報並且包括科學家及工程師的培訓與儲備,

傳聞中國已經籌劃20年之久,20201201.一舉成功登陸月球挖掘礦石及土壤約2千克的重量是當時45年前美國及蘇聯的3倍有餘.

20世紀美國阿波羅太空船計劃從月球累計帶回380多千克月球樣品，蘇聯依靠無人飛行器分3次共獲得了300餘克月球土壤及礦石;但美國,蘇聯等國家的航天器均未到訪過月球火山胡活動區域呂姆克山脈附近採集礦石及土壤返回地球。

由此觀之美國新成立的太空軍及太空軍總部,川普總統撥出特別預算經費,加速研究及加強太空火箭的製造,期望在2025年之前,再度登陸月球與中國一較高下,國際戰略專家認為,新一輪的太空爭霸戰,由美國和中國雌雄對決,精彩萬分,中國的嫦娥月神(雌)將打敗美國的阿波羅月神(雄).

Chinas Change-5 lunar probe successfully completed its second braking at 8:23 p.m. Sunday (BJT), entering a circular lunar orbit 200 kilometers above the moon and getting ready for the landing operation, according to the Lunar Exploration and Space Program Center of China National Space Administration (CNSA).

This follows its first braking one day earlier, which took place at a position about 400 kilometers above the moon and enabled it to be captured by the moons gravitational field and fly in an elliptical lunar orbit.

The second braking brings it closer to the moon. Over the next week, the probe, composed of four parts – the orbiter, lander, ascender and Earth re-entry module – will perform multiple complicated tasks on a tight schedule. 

The four parts will separate into two pairs. The lander and ascender will head to the moon and collect samples, while the orbiter and Earth re-entry module will continue to fly around the moon and adjust to a designated orbit, getting ready for the docking with the ascender.

The landing operation is expected in three days. Once touched down on the lunar surface, the lander will collect two kilograms of lunar sample. 

It will shovel some surface material, drill a two-meter-deep hole and extract the soil from inside it, which will act as an archive of the moon, with the bottom recording information from a billion years ago, and the top more closely reflecting the present day. 

Once the samples are secured, the ascender will take off from the lunar surface to transfer the moon samples to the re-entry capsule waiting in lunar orbit, which will then carry them back to earth.

The sampling work and the take-off of the ascender from the lunar surface need to be completed within 48 hours, according to Liu Jiangang, chief of the command team in Beijing.
