在最后著陸階段,過大推力使“維克拉姆”號失控

 Extra brake thrust may have sent Vikram out of control in home stretch

在最后階段,過大的制動推力使“維克拉姆”號失控

BENGALURU: When silence descended on the Isro mission control and millions of Indian homes minutes before Vikram was to touch down on the Moon at 1.53am on Saturday, many thought the lander had too little thrust to brake to a halt. A day later, Isro scientists are looking at whether Vikram had too much braking thrust, which spun it out of control.

班加羅爾:“維克拉姆”號原計劃在周六凌晨1點53分著陸,最后幾分鐘,ISRO控制中心和無數印度家庭陷入沉默,許多人認為著陸器的推力太小,剎不住。一天后,ISRO的科學家們研究“維克拉姆”號的制動推力是否太大,導致其失控。

"We thought one of the thrusters may have underperformed," said an Isro scientist. "But after some preliminary analysis, it looks like a thruster overperformed."

ISRO的一位科學家表示:““我們認為其中一個推進器可能表現不佳,經過一些初步分析,似乎是推進器運轉過度了。”

Descending from its orbit 30km from the Moon, Vikram had achieved perfect roughbraking for 10 minutes, reducing its velocity from 1,680 metres per second to 146 metres per second. Soon after the fine-braking that signalled Vikram's last 5km descent to the Moon, mission control lost contact with the lander.

“維克拉姆”號從距月球30公里的軌道上降落,在10分鐘內實現了完美的制動,速度從1680米每秒降至146米每秒。“維克拉姆”號最后5公里下降時精細制動,不久之后,地面控制中心與著陸器失去了聯系。

Every failure is a lesson to perfection.

每一次失敗都是為通向完美而積累經驗。

Every failure is a stepping stone to success !. I am sure our scientists will use this experience for much greater success

失敗是成功的墊腳石!

我相信我們的科學家會得到經驗教訓,以后會取得更大成功的

I am no scientist, but a question aries why we lost contact? brakes can send the vehicle out of control. but loss of communication?

我不是科學家,為什么會聯?

剎車會使其失去控制。失聯又是怎么回事?

 

Bhai Sahab

Hats off to the effort. Thats it !! ISRO Well Done.

向ISRO的努力致敬。ISRO做得好.

Aim high to challenge yourself

USA (12 Attempts) Russia (7 Attempts) & China (Attempts)

India’s First Attempt is 95% Successful !!!

Proud of our ISRO Scientists

美國嘗試了12次,俄羅斯嘗試了7次,中國也嘗試了7次

印度首次嘗試就成功了95%!

為我們的ISRO科學家感到驕傲

ISRO''s track record is much better than that of many advanced countries..and they shall overcome this also asap.

ISRO的表現比許多發達國家要好得多。他們會盡快克服困難的。

What caused the signal loss? It is a mystery. I hope no sabotage is there.

是什么導致失聯的?這是一個謎。希望沒有人在上面蓄意搞破壞。

 

Rajeev Goel• 4 hours ago

This is the second time in as many years that the mission got aborted because of communication failure. Our geo satellite was lost because of last minute signal loss. Is this jamming of signals by China that resulted in this fiasco.

這是第二次因通訊中斷而流產。是中國信號的干擾導致了這次失敗嗎?

Few advises from a scientist for future programs

  1. No politicians to attend ISRO during mussion. They distract the jobs.
  2. No publicity till the mission is over.

3.no media to be entertained during mission.

對未來項目的一些建議(來自一位科學家):

  1. 禁止印度政客在執行任務期間進入ISRO參觀。會分散注意力的。
  2. 在任務結束之前不要公開。
  3. 執行任務期間不接待任何媒體。

ARUP MALLIK• 22 mins ago

This is a thought set of advises. I also subscribe this and am sure many Indians feel the same.

好建議。我也同意,相信許多印度人也有同感。

Loss of communication implies extensive damage to the lander Vikram. Normally such extensive damage could only be expected if Vikram had crash-landed on the moon. But ISRO has reported the Lander to be still 2.1 km above the moon surface at the time of communication loss. It is just possible that there may be a flaw in the instant to instant height calculation software. Lander may have reached the moon surface at high speed and crashed when the computation software still showed a distance of 2.1 km to the moon surface. It needs to be investigated.

通訊中斷意味著“維克拉姆”號著陸器受到嚴重損壞。正常情況下,只有迫降了,才會造成如此嚴重的損壞。ISRO報告稱,在通訊中斷時,著陸器仍在月球表面2.1公里以上。可能是瞬間高度計算軟件存在缺陷。著陸器可能已經急速抵達月球表面了,當計算軟件仍然顯示距離月球表面2.1公里,這時候著陸器其實已經墜毀了。好好調查一下吧。

Your guess makes a good sense buddy. I also think so.

伙計,你的猜測很有道理。我也這么認為。

ONE LINE CHALLENGER• 1 hour ago

Excellent point. Who wrote the code? Infy? Or TCS?

說得好。這軟件的代碼是誰寫的?印孚瑟斯?還是塔塔 ?

Person responsible for controlling the thrust knew pm modi was watching from the gallery. Maybe he got nervous at a crucial moment. No VIPs should be allowed in delicate operations.

負責控制推力的人知道莫迪總理正在走廊里觀看。也許他在關鍵時刻緊張了。在精細操作期間應該禁止貴賓觀看。

 

Robert Samuel chandrasekaran• 2 hours ago

Not a failure.so far so good.This is a learning curve.70 percent of moon landing is a failure according to NASA.So let us not get disheartened.

據NASA稱,70%的登月嘗試是失敗的。所以,我們不要灰心喪氣。

 

Ishaq• idupula paya • 2 hours ago

when Modi consoled by hugging, Dr.Sivan,yesterday, I, got the same feeling as if a father is consoling his failed child in an exam.

We are fortunate to have a statesman and a leader like Modi ji.

昨天,當莫迪擁抱安慰ISRO主席時,有一種父親在安慰考試不及格的孩子的感覺。

我們很幸運有莫迪這樣的政治家和領導人。

India is not doing any Fake Missions like US did in 1969 when Americans landed on Moon.

印度沒有像美國1969年登月時那樣作假。

Don''t celebrate before success. Don''t create hype when you have critical missions which can go either way. Success and failure are common in these cases.

成功之前不要慶祝。執行重要任務時,不要大肆宣傳,因為任務有可能成功,也有可能失敗。成功和失敗都是常事。
